COVID-19 pandemic in Bulgaria

The COVID-19 pandemic in Bulgaria was a part of the worldwide pandemic of coronavirus disease 2019 ( COVID-19 ) caused by severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2 ). The virus was confirmed to have spread to Bulgaria when the country's first cases, a 27-year-old man from Pleven and a 75-year-old woman from Gabrovo, were confirmed on 8 March 2020. Neither of the two had traveled to areas with known coronavirus cases which is maybe because the PCR test that was used is defective. The man tested positive for the virus after being hospitalized for a respiratory infection, and authorities announced plans to test several people who were in contact with the two individuals. Two other samples in Pleven and Gabrovo were positive on 8 March. Patient zero remains unknown.

After the number of patients in the country had reached 23, the Bulgarian Parliament voted unanimously to declare a state of emergency from 13 March until 13 April. A 14-day preventive house quarantine was introduced for citizens who have been in contact with a COVID-19 patient or have returned from an overseas region with a high number of cases. For patients tested positive for the virus a 21-day house quarantine was introduced. This time span is counted from the day a subsequent test comes out negative after they have been treated in a hospital or at home. After the World Health Organization (WHO) has established that COVID-19 is more resilient than the initial data was showing, the National Crisis-management Staff increased the recovery house quarantine by a week to 28 days. With the continuing increase of COVID-19 cases on a daily basis, the Bulgarian government requested on 1 April that Parliament extend the state of emergency by one month until 13 May.

As of 5 February 2023, a total of 4,612,386 vaccine doses have been administered.

Background
A National Crisis-management Staff was formed by the Bulgarian government on 5 March to deal with the coronavirus pandemic. The Government has appointed Major general professor Doctor Vencislav Mutafchiyski as the Chairman of the Staff. MG Prof. Dr. Mutafchiyski is the Director of the Military Medical Academy and the most senior medical officer of the Bulgarian Armed Forces. He is an abdomen (stomach) surgeon and epidemiology is not among his specialties. The MMA combines the military medical services of the country in their entirety with several hospitals in the capital Sofia and around the country. At the same time it is one of the country's leading medical institutions and possesses large medical treatment capacity and know-how. The Staff fulfills a direct operational role in the management of the crisis and its decisions are implemented through executive orders of Bulgaria's Prime Minister and the country's Minister of Health.

On 23 March a separate Medical Council for dealing with the coronavirus pandemic was appointed by the Prime Minister. The council was chaired by Professor Kosta Kostov, a leading pulmonary disease expert. The council's mission was to provide the government with complementary analysis and action proposals and the general public with professional guidance and information. Unlike the National Crisis-management Staff, which is a formal national institution with executive power and tasks, the council had mostly a knowledge-based advisory role. On 4 April the Medical Council dispersed, having achieved its purpose, according to its chairman.

February
Limited border health monitoring was introduced in February 2020.

8 March
On 8 March 2020, Bulgaria confirmed its first two cases, a 27-year-old man from Pleven and a 75-year-old woman from Gabrovo. Neither of the two reported having traveled to areas with known coronavirus cases. The man tested positive for the virus after being hospitalized for a respiratory infection, and authorities announced plans to test several people who were in contact with the two individuals. Two other samples in Pleven and Gabrovo were found positive on 8 March. Patient zero remains unknown.

On the same day, the hospital in Gabrovo requested additional personnel from other hospitals in the country, as it only had three communicable diseases specialists. All of its internal medicine specialists have been quarantined after one of the four initial cases was confirmed to be a nurse at the hospital. The government issued a nationwide ban on closed-door public events. The origin of the outbreak remains unknown, and the Ministry of Interior is tracking down all individuals who have been in contact with the patients. As of 8 March 254 suspected cases were under quarantine across the country.

10 March
Two additional cases were confirmed in Sofia on 10 March 2020: a 74-year-old man and his 66-year-old wife. Both have arrived from Lom two weeks prior to admission. The woman died on the next day, becoming the first COVID-19 death in the country.

11 March
A suspected case of a 33-year-old man was reported by the Saint George Hospital in Plovdiv on 11 March. The same day, a 40-year-old woman in Varna showed COVID-19 symptoms on CT scan, although regional health authorities have not yet confirmed the case.

12 March
By 12 March, the number of cases had increased to 23, most of them in Sofia. Many of these had been in contact with the elderly couple admitted to the Pirogov Hospital on 10 March.

13 March
On 13 March, after 16 reported cases in one day, Bulgaria declared a state of emergency for one month until 13 April. Schools, shopping centres, cinemas, restaurants, and other places of business were closed. All sports events were suspended. Only supermarkets, food markets, pharmacies, banks and gas stations remain open. Additionally, all arrivals from Italy, Iran, Spain, China and South Korea were placed under a mandatory 14-day quarantine. There were 13 breaches of quarantine; patients involved were returned to treatment facilities and warned of repercussions, including fines and prison sentences.

14 March
On 14 March, a second death and a third case in Pleven were reported. The second death the virus was the 74-year-old husband of the first death. Late in the evening on 31 March a member of parliament was tested positive for the virus. All MPs were urgently tested on the following day. If some of them are also tested positive, the Parliament will be adjourned. Options for the MPs to continue their legislative work (including voting) online from home under isolation are being explored.

15 March
The number of confirmed cases in Bulgaria rose to 51 on 15 March. A total of 83 tests were done at the Military Medical Academy, of which six were positive, and 51 were processed at the National Reference Laboratory, of which two were positive. In Varna, one test out of 12 samples proved positive.

The total number of cases increased to 127 and the first recovery occurred.

21 March
The number of cases increased to 142 by noon, and three patients had recovered. Two cities, Dobrich and Shumen, confirmed their first cases, the latter related to the Bansko cluster. There are 84 male and 58 female patients, the youngest being 4 years old, and the oldest 81 years old. More than 5,000 tests had been carried out, and an additional 10,000 tests would be made available at short notice.

24 March
The cases increased to 218 and the first case in Stara Zagora province was confirmed. A man from the town of Kazanlak was admitted in the Infectious unit in the hospital in Stara Zagora. He is believed to be 60 years old and returned from France on 14 March.

1 April
The province of Ruse reported its first case as part of 23 new infections across the country, bringing the total to 422. In addition to Ruse, 10 new cases were reported in Sofia, two each in Blagoevgrad, Burgas, Dobrich and Plovdiv, and one each in Haskovo, Kardzhali, Sliven and Stara Zagora. Two deaths were registered – a 57-year-old man in Kyustendil and a 40-year-old man in Sofia. Hassan Ademov from the Movement for Rights and Freedoms became the first Bulgarian member of parliament to contract the virus, forcing the announcement of a mass test on 2 April that would cover government staff and all 240 MPs.

14 April
The village of Panicherovo in Stara Zagora Province was placed under quarantine, after a COVID-19 positive man escaped from a hospital where he was being treated and returned to the village.

15 April
The Ministry of Interior established checkpoints limiting movement in and out of the predominantly Roma-populated Sofia neighborhoods of Filipovtsi and Fakulteta. The neighborhoods were categorized as COVID-19 clusters by the National Crisis Management center.

16 April
In a late night emergency joint press conference of the Minister of Interior, the Minister of Health, and the Chairman of the National Crisis Management center, it was announced that entering and exiting Sofia would be severely limited until further notice following increased traffic out of the city before the Easter holidays. Following numerous imported cases from Britain (e.g. a 78-years old Briton whose sister was known to have been infected by the coronavirus and a Bulgarian repatriate from Varna ) the Civil Aviation Authority put a ban on all flights between Britain and Bulgaria. The decree refers to the sharp increase in COVID-19 cases in that country for the last weeks surpassing the level in other concerned countries. Three days before the measure was implemented the Governor of Varna Oblast had expressed his apprehension regarding the flights between Varna and London.

20 April
The ministry of Health announced the renewal of planned surgeries and hospitalizations, immunizations, child and prenatal care. These will be conducted under strict schedule on Tuesday and Thursday of each week.

21 April
The hour limitations on entering and exiting Sofia were lifted.

27 April
The prohibition of the passenger air traffic between Bulgaria and Britain was revoked after 11 days.

1 May
Compulsory mask-wearing in open public spaces was rescinded with a new decree by the Minister of Health. National parks outside municipal boundaries, closed to the public on 20 March, were reopened, with local authorities commissioned to provide the organization for visitors.

2 May
The first case in the province of Razgrad was confirmed, meaning that now 27 out of 28 provinces have proven cases of COVID-19. On this day also, was recorded the first death of a medic. A 43-years-old female doctor from Sliven died after contracting the disease. She worked in the Infectious Diseases Department in the city of Sliven.

4 May
Dr Andrea Ammon, Director of ECDC, listed Bulgaria as the only country monitored by the Centre still seeing an increase in newly registered cases.

6 May
Checkpoints outside provincial centres were removed and restrictions limiting inter-city travel lifted.

9 May
Targovishte, the last Bulgarian province without any registered cases yet, had its first COVID-19 case confirmed.

14 May
As of 14 May at 00:00, the national emergency was lifted, and in its place was declared a state of an emergency epidemic situation. Organ transplantations are allowed again after a 2-month ban. Parks are open for the use of all. Most of the anti-epidemic measures are still valid. The 14-day quarantine for everyone who enters the country remains. Schools and daycares remain closed, as well as shopping centers and indoor restaurants.

21 June
Bulgarian tennis player Grigor Dimitrov announced on his Instagram account that he has tested positive for COVID-19 which lead to the cancellation of Adria Tour, where he had participated the weeks before. Multiple other tennis players tested positive the following days.

1 August
It was announced that Bulgarian tennis player Viktoriya Tomova had tested positive for COVID-19 on the site of a tournament in Palermo, Italy which happened to be the first official pro tennis event after the pandemic began.

23 August
Bulgaria's Minister of Youth and Sports Krasen Kralev tested positive.

25 October
Bulgarian Prime Minister Boyko Borisov tested positive. He said on Facebook that he had "general malaise."

November
By 10 November, Boyko Borisov had recovered from COVID-19.

On 28 November 2020, Bulgaria entered a second lockdown, which was characterized as a "partial" one due to being less strict than the first, and was envisioned to be in place until Christmas. This decision was regarded by many experts as being long overdue because of the huge strain on the country's health system, resulting in many people not being able to receive access to adequate medical care, and the Prime Minister faced strong criticism from other politicians.

December
On 18 December 2020, the government confirmed that the lockdown will be extended until 31 January 2021.

March 2021
From 22 March until 31 March 2021 the country was under another lockdown, the third one since the start of the pandemic.

May 2021
During the second half of the month the weekly positivity rate fell to below 4%, with the number of people testing positive the lowest since early October 2020.

June 2021
In June 2021, genomic sequencing confirmed the presence of the Beta and Delta variants in Bulgaria.

July 2021
By the second half of July 2021, Delta had emerged as the dominant variant (showing up in over 50% of genomic sequencing samples), starting to displace Alpha.

August 2021
By mid August close to 99% of the samples tested positive for Delta.

October 2021
Due to the worsening epidemiological situation, a "green certificate" that could be obtained by showing proof of vaccination, recovery from an infection or a negative COVID-19 test was introduced as a requirement for many public activities from 21 October. It was also regarded as a way of avoiding another lockdown.

November 2021
The presence of the 'Delta Plus' subvariant was confirmed in November 2021.

December 2021
On 22 December 2021, the Cibalab private laboratories signalled that the Omicron variant had been discovered in six virus samples. Iva Hristova, head of the Center for Infectious and Parasitic Diseases, insisted that the presence of Omicron will need to be confirmed through genomic sequencing, for which the private laboratories do not possess the technology, with accurate findings expected to become available after the new year. Mathematician Ognyan Kunchev has stated that the sequencing process in Bulgaria takes around 10 days and needs to be sped up as well as cover more samples. On 29 December 2021, virologist Radka Argirova who serves as an advisor of Prime Minister Kiril Petkov stated that there are strong indications that Omicron is already in Bulgaria, referring to a number of suspected cases, all of them among people who had travelled abroad.

Variant changes
On 2 January 2022, the first 12 cases of the Omicron variant were officially confirmed by the health authorities. 11 of them were in Sofia City Province while 1 was in Sofia Province, with 7 of the cases among non-vaccinated, 5 among vaccinated and none among people with a booster dose. Only one of the people infected with Omicron had recently been abroad. Omicron was found in 4.4% of the 275 sequenced samples with Delta making up the rest. None of the infected required hospitalization. As of 10 January 2022, 52 new cases of Omicron had been discovered, based on 505 sequenced samples for the period up to 3 January, with Omicron accounting for 10.3% of the swabs, with the rest being Delta. As of 19 January 2022, 227 new cases of Omicron had been identified, based on 522 sequenced samples for the period up to 10 January, with the ratio of Omicron to Delta being 43.5% to 56.75%. By mid to late January 2022, Omicron had emerged as the main variant, accounting for 74.5% of cases by 20 January, being found in 249 out of 334 samples.

Rise in cases
On 12 January 2022, 7062 new cases were registered, the most since the start of the pandemic, exceeding the previous record number of 6816 daily positive tests reported on 27 October 2021. After the health authorities reported 9996 positive tests on 18 January 2022, on the next day the number of registered daily cases surpassed 10 000 for the first time, with 11 181 new infections announced for the previous 24 hours. On 26 January 2022, a new high of 12 399 official cases was reported by the Ministry of Health.

Reinfections and coinfections
As of 14 January 2022, there have been 4692 officially recorded reinfections in Bulgaria. According to an academic paper analyzing the period between March 2020 and December 2021, there had been 31 cases of people infected three times and one instance of an individual contracting COVID-19 for a fourth time. In late January 2022, the first instance of COVID-19 and influenza A (strain H3N2) co-infection was confirmed.

Rules regarding COVID-19 positive people
From 11 January 2022, the mandatory isolation requirement for people with a positive COVID-19 test was reduced from 14 to 10 days.

February 2022
On 4 February 2022, the health authorities confirmed the presence of the BA.2 subvariant of Omicron, which had been discovered in 7 samples from Sofia, Bourgas and Targovishte. The BA.3 sublineage was detected as well. According to assessments, the fifth wave of the virus, which had begun without the full subsiding of the fourth, peaked in late January and early February.

April 2022
On 1 April 2022 the emergency epidemiological situation in Bulgaria was lifted by the Council of Ministers, resulting in the abolishment of virtually all non-pharmaceutical interventions such as capacity limits for venues and mask mandates, with protective face coverings continuing to be recommended in indoor spaces and any high risk environments. The decision to drop restrictions has generally been regarded as being in line with the improved epidemiological situation, following the trends in other European countries, though some experts have characterized it as hasty due to the low vaccination coverage of the population and cautioned that it could lead to false sense of calm that the pandemic is over. Concerns have also been expressed about the reduction in the testing for the virus. Members of the business sector have criticized the declaration of an end to the epidemiological situation as an excuse for the government to stop offering financial compensations. According to a law passed by the National Parliament on 13 April 2022, the burden for the introduction of new measures will to an extent shift from the Minister of Health to the regional health authorities, with the restrictions thus envisioned to be regional rather than nationwide. However, the Health Minister retains the prerogative to introduce pandemic control measures. In late April 2022, mathematician Nikolay Vitanov stated that the reproduction number for the virus in Bulgaria is 0.82, characterizing the situation in the country as lacking the diffuse spread of Western Europe, which he believed to have been a factor behind the decision to remove the restrictions.

May 2022
From 1 May 2022, the pandemic-related requirements regarding the entry of foreign citizens, such as proof of vaccination, were dropped.

June 2022
On 29 June 2022, the Ministry of Health announced that the presence of the BA.5 subvariant of Omicron had been confirmed after genomic sequencing of 88 samples from all over the country taken in the period from 5 May to 3 June. BA.2 was by far the dominant subvariant, accounting for more than 75% of the cases.

July 2022
In July 2022, the BA.5 Omicron subvariant began emerging as dominant over the other ones, being the most frequently detected in samples. It had spread the most in the capital Sofia.

On 25 July 2022, face masks once again became compulsory for all citizens using public transport in Sofia.

August 2022
From 4 August 2022 there was a further tightening of the epidemiological control measures in the capital, with face masks starting to be required for most indoor spaces as well as other requirements pertaining to social distancing, disinfection and capacity limits being introduced. Following the appointment of Asen Medzhidiev as caretaker Health Minister, from 11 August 2022, the pandemic-related measures in Sofia, especially those pertaining to masks, were once again relaxed, and a large amount of free rapid antigen tests were provided. From 25 August 2022, the mask requirement for public transport was dropped. Facial coverings remained compulsory in medical settings.

October 2022
In October 2022, two additional Omicron subvariants - BQ.1.1 и BM.1.1 - were confirmed to be present in the country. BA.5x remained the dominant subvariant, being found in around 71% of genomic sequencing samples for the period between 11 September and 12 October.

November 2022
In mid November 2022 it was confirmed that from 17 November all public health measures related to COVID-19 will be lifted.

January 2023
In January 2023 the XBB.1.5 strain was detected for the first time, being discovered in an individual from Sofia.

Response
At the time of the announcement, schools had already been closed until 11 March due to an influenza B epidemic. A massive increase in influenza B cases prompted suspensions of routine medical examinations, and a recommendation by the government for suspension of lectures at universities. According to the latest Ministry of Health data, there were 2063 intensive care and 740 infectious disease hospital beds in the country, with a total of 1605 ventilators across the health system. However, Chief Health Inspector Angel Kunchev stated on 5 March that there is a shortage of medical personnel.

Following the announcement of positive SARS-CoV-2 test results, the Bulgarian government immediately banned the exports of protective equipment and placed orders for masks and protective suits to local manufacturers. In addition, 30,000 masks and 50,000 protective suits will be delivered by Turkey. Some 111,000 suits and masks are required every month and the government plans to distribute them to health workers, social assistants, law enforcement personnel and border guards. Sofia Municipality has increased disinfections to four times daily at public institutions and in public transport. Personnel in all hospitals was reportedly being screened for the disease, but in April a nurse in Vidin reported that she was refused a test after caring for a positive patient, as the hospital in the city had no testing kits.

By mid-March, large-scale imports of protective equipment from China, India and Vietnam had begun. Many volunteers were also signing up to join the handling of the crisis, including Nikola Vaptsarov Naval Academy cadets.

On 30 March, the Minister of Health Kiril Ananiev decreed wearing masks in public mandatory, both outdoors and indoors, despite nationwide protective equipment shortages and soaring prices. The policy seemed to contradict Ananiev's earlier statement from 9 March that producing the needed gear "will take months". Under article 209a of the Health Law, which was passed on 13 March and does not discriminate between offenses, failing to wear a mask in public would result in a fine of BGN 5,000 (EUR 2,555). On 31 March Ananiev rescinded the decree, citing "a lack of public consensus" on the measure. On 6 April 2020 the National Assembly passed amendments to the State of Emergency law from 13 March. The fines for breaking the measures against the pandemic were reduced. As of 6 April, there were 1340 fines worth approximately EUR 3,500,000 imposed, mostly for walking in the park. On 11 April, the Minister of Health reinstated the mask-wearing measure for the period 12–26 April 2020. The new decree included "towels, scarves, et al," despite reports that "[t]here is only limited indirect evidence that non-medical face masks are effective as a means of source control." On 24 April 2020, compulsory mask-wearing in public was extended to 13 May 2020, excluding open public spaces after 1 May 2020.

Nearly BGN 14,000,000 (EUR 7,160,000) had been donated by 3 April, with 48% coming from private companies, 26% from public campaigns, 19% from individual donors and 7% from foundations.





On 10 April, Sofia City Prosecutor's Office indicted Prof. Asena Stoimenova, chairwoman of the Bulgarian Pharmaceutical Union, under article 326 of the Penal Code following "a series of statements inciting fear in the population during the state of emergency." In an interview for Bulgarian National Television, Stoimenova had stated that the market for protective gear appears to be normalizing following the shortages the country experienced at the outbreak of the pandemic, but disruptions in the international pharmaceutical trade might lead to shortages of other medical supplies in Bulgaria.

When interviewed in December 2021, Ventsislav Mutafchiyski stated that Bulgaria had followed a COVID-Zero rather than a "living with COVID" strategy until 13 May 2020.

Testing
As of 24 March, there are 5 laboratories testing for COVID-19 in the country with a capacity of 300 tests per day. The total number of tests done by 26 March was 6,454, with 264 confirmed cases and a rate of infection around 4.1%.

On 27 March, the Ministry of Health announced that the country now has the capacity to process between 1,000 and 1,200 tests per day, at an estimated cost of BGN 930,000 (EUR 475,000) per month. Two additional methods of testing would be introduced at later stages of the pandemic – fluorescence immunochromatographic tests (up to 20,000 per day) and the so-called 'quick' tests (up to 40,000 per day). Major General Ventsislav Mutafchiyski called all three types "equally important", as the PCR ones provided reliable data, while the fluorescence tests could speed up the process before quick ones are applied to establish how many people have acquired immunity. However, Mutafchiyski later added that rapid tests are considered "unreliable" and therefore mass screening would be "meaningless".

Conversely, Prof. Radka Argirova, chairman of the National Expert Board in Virology at the Bulgarian Doctors' Union, urged increased rapid testing to discover asymptomatic cases, avoiding the chance of a future second peak and terminating the epidemic progression. "Aggressive, complete screening" of the population was also advocated by Dr. Rumen Hichev, a Bulgarian medical professional based in the United States and part of a medical advisor team to the White House. According to Hichev, the Bulgarian government had reacted quickly, but without mass screening to establish asymptomatic spreaders, any effort would be behind the course of events.

On 5 April, the Ministry of Health announced a total of 15,599 tests had been performed to date in eight laboratories across the country. The government announced that by 18 April, 26 417 tests had been performed.

As of October 2020, there were 65 laboratories offering PCR testing, the results of which were recognized for travel abroad.

On 22 October 2021, it was announced that the record number of 47,370 tests (both PCR and rapid antigen) had been performed over the last 24 hours, which was attributed to the introduction of the "green certificate" (obtained courtesy of a vaccination, proof of recovery from COVID-19 or a negative test) requirement for many public activities.



Medication
After testing positive for COVID-19, business magnate Kiril Domuschiev announced that his company will procure chloroquine from foreign sources and donate it to the national coronavirus task force. However, chloroquine, a quinine drug, has been proven to provide no benefit for COVID-19 patients. The Bulgarian government is looking into import opportunities from China and domestic production by local pharmaceutical companies. Exports of all quinine-based drugs were prohibited until further notice, and 35,000 doses of quinine-based Metamizole for export have been diverted for domestic consumption. Another 250,000 doses of the drug can reportedly be produced on a short notice by local pharmaceutical companies. On 3 April, the government negotiated the delivery of 171,429 packs of Hydroxychloroquine sulfate and 30,000 packs of azithromycin from the China National Pharmaceutical Group. The shipment was delivered using a NATO Boeing C-17 Globemaster III piloted by a Bulgarian Air Force captain; the cargo also included more than 1,600,000 masks and 50 ventilators.

Bulgarian biotechnology company Micar21 has been developing a general coronavirus vaccine in the past four years, and announced that it will begin clinical trials of a SARS-CoV-2 vaccine based on this research in mid-2020. The company announced that with government support in funding and shorter clinical trial protocols, the drug could be synthesised in two months.

Colchicine has been offered to patients since April 2020 with some promising results, but the degree of effectiveness as well as the precise dosage remains under evaluation.

Some medical practitioners have controversially prescribed ivermectin in an off-label fashion, contrary to international medical guidelines.

Projections
According to a research conducted by the Institute for Health Metrics and Evaluation at the University of Washington, the pandemic was expected to reach its peak in Bulgaria in the end of April. The projections were assuming full social distancing through May 2020. The research listed 856 ICU beds in the country and projected no shortage of medical resources.

Criticism
Georgi Todorov, a Bulgarian doctor with experience in viral breakouts in Ghana, criticised the handling of the COVID-19 threat. In particular, Todorov stated that Bulgaria's health administration is so rife with nepotism that it cannot come up with any coherent response; as a result, infectious disease specialists were not taken into account when formulating response policies, and no specific locations were designated for potential COVID-19 cases. Todorov further assumed that infected individuals may have not been identified because of improper application of testing procedures. Following the end of the first lockdown in Bulgaria, there has been criticism due to the lack of sufficiently strict non-pharmaceutical interventions implemented by the governments.

Discrimination
Some Roma communities, like the one in Burgas, were surveilled with thermal drone cameras. Other communities, from places like Yambol or Kyustendil, were sprayed with disinfectants from helicopters and crop dusters. Ognyan Isaev, a Roma activist, expressed concerns that if the pandemic worsened, discriminatory measures could be reinstated.

Economy
The Bulgarian government has enacted a series of measures aimed at reducing the economic impact of the COVID-19 pandemic to businesses and individuals.

60/40 measure
The so-called "60/40 measure" is a short-term instrument to help businesses retain their employees during the COVID-19 crisis. The state will cover 60% of employees' insurable earnings, as well as the social insurance contributions owed by the employer. The measure is in effect for the duration of the State of Emergency announced on 13 March 2020, but for no longer than 3 months.

State-backed interest-free loans program for individuals
The program provides state-backed, interest-free, zero-fee loans to individuals, deprived of the opportunity to work as an effect of the COVID-19 pandemic. The program is implemented by the Bulgarian Development Bank in partnership with a number of banks from the private sector.

Self-employed individuals and individuals under an employment contract are eligible for an interest-free loan of up to 4,500 BGN (2,300 EUR), with a grace period between six and twenty-four months, paid out in three monthly installments of 1,500 BGN.

Working capital loans for SMEs
The program, financed by the Bulgarian Development Bank, provides working capital loans of up to 300,000 BGN, aiming to provide liquidity to SMEs affected by the COVID-19 pandemic.

Grants for small and micro-enterprises
Small and micro-enterprises are eligible for state grants between 3,000 and 10,000 BGN, provided they have reported at least 20% drop in monthly revenue compared to the same month in 2019.

Moratorium on loan repayments
The board of directors of the Bulgarian National Bank established a private moratorium on loans repayments, as presented by The Association of Banks in Bulgaria, which allows for payments deferral of up to six months.

Impact
Bulgaria recorded 31,643 newly registered unemployed for the period between 13 March to 1 April. From these, 17,793 claimants stated that job losses were a direct consequence of the pandemic, and 12,661 registered in the week 23–27 March alone, compared to 4,561 for the same period in 2019. The number of unemployed continued to rise throughout April. According to a statistic released by the Agency of Employment, as of 28 April 2020, there were 291,426 registered unemployed, a rise of 90,405 since the introduction of the national emergency. A survey conducted by the Bulgarian Industrial Association showed that initially only 8% of the companies were willing to use the government stimulus package, which quickly became colloquially known as 'the 60/40 measure'. The proposal envisions the government paying 60% of the impacted businesses' employee wages for up to three months, as long as the companies refrain from lay-offs.

Views of the general public
A Gallup opinion poll from April 2020 revealed that 77% of the citizens expressed support for the lockdown-related pandemic control measures taken by the authorities in the country. А "Trend" survey between 1 and 5 April 2020 saw 35% demand stronger measures against COVID-19, 39% rating the government policies as sufficiently strict and 23% expressing the opinion that the pandemic controls need to be relaxed. А nation-wide opinion sampling of 1151 adult Bulgarian citizens conducted by the Bulgarian Academy of Sciences, the University of National and World Economy, Bulgarian Sociological Association and the Union of Economists of Bulgaria in mid 2021 showed that the support for a "stay-at-home" order was 60%, with 75% approving of mask mandates and 74% agreeing with bans on public gatherings. According to a Eurobarometer poll conducted between March and April 2021 82% of Bulgarians expressed a wish that the European Union acquires enhanced prerogatives in handling crises such as the COVID-19 pandemic.

Assessments
An April 2022 academic paper characterized Bulgaria as "perhaps the most heavily affected" Eastern European country in terms of excess mortality data, with the late imposition of restrictions on social mobility and the insufficient government control deemed likely to be the major factors behind this statistic. The authors also highlight the generally better health outcomes in major population centers as opposed to more peripheral regions of the country. The high degree of income inequality in Bulgaria has been associated with corruption and lack of institutional trust, contributing to many issues with the country's response to the pandemic.
