COVID-19 pandemic in Chad

The COVID-19 pandemic in Chad was a part of the ongoing 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 reached Chad in March 2020. As the third least developed nation in the world, according to the HDI in 2019, Chad has faced unique economic, social, and political challenges under the strain of the COVID-19 pandemic.

Background
On 12 January 2020, the World Health Organization (WHO) confirmed that a novel coronavirus was the cause of a complex respiratory illness in a cluster of people in Wuhan City, Hubei Province, China, which was reported to the WHO on 31 December 2019.

The case fatality ratio for COVID-19 has been much lower than SARS of 2003, but the transmission has been significantly greater, with a significant total death toll. Model-based simulations for Chad indicate that the 95% confidence interval for the time-varying reproduction number Rt for Chad fluctuated around 1.0 in late 2020 and early 2021. Studies on the ground have illustrated that the country is not adequately equipped to handle a pandemic. With roots tracing back to a violent and recent colonial history, many sectors of the Chadian economy and government are under-developed. Of specific concern regarding a global pandemic, the health sector faces many challenges in Chad. Issues such as geographic accessibility, government and foreign-aid funding conflicts, brain drain emigration, and poor infrastructure shape the scope of care systems. Understanding the context of the Chadian health sector, pre-pandemic, helps to set a foundational understanding for the struggles the nation now faces and paths for the future.

Response
As a preventive measure, the government cancelled all flights into the country, except for cargo flights. Furthermore, the government responded with similar and standard global practices of mandating mask wearing in public spaces, creating a curfew from 8 pm to 5 am, checking temperatures at airports and supporting "quarantine hotels", as well raising public awareness of the viral threat through campaigns and advertisements. Schools, public life such as bars and social clubs, and government work was closed along with social distancing requirements. Of importance to note is the paradox of low corona virus cases in Chad given the strained health systems in place. Researchers have theorized that these low numbers may have a multitude of answers: notably the population's previous exposure and experience with infectious disease, as well the average age of the population, 52.8 years, being under the highest levels of "at-risk ages" for the COVID-19 pandemic, around 65 years old and poor records and/or testing of cases. The IMF details responses the Chadian government has worked to implement such as subsidizing the agricultural sector, tax break plans, focusing on essential imports such as food distribution, suspending household bills, and clearing domestic debt. Of importance to track in response to the pandemic is Chad's increasing ties with China. China has a relationship with the nation through generous loan programs, and throughout the pandemic these ties have increased as China has stepped up to provide food distribution aid as well as medical equipment and support in zones of active violence in Chad.
