January–February 2020
In late January 2020, two students living in Connecticut were monitored for displaying coronavirus-like symptoms. The first student attended Wesleyan University in Middletown and tested negative for COVID-19, and instead had a case of the flu on January 27. The second student monitored for the virus was attending the 2020 Yale Model United Nations Conference at Yale University in New Haven, and was also diagnosed with the flu on January 31. On January 28, a student from Uncasville, who had traveled to China, was suspected to carry the virus, but tested negative and was cleared to return to school the next day.

On February 6, the Connecticut Department of Public Health released a document with information intended for schools to prevent the spread of the virus. The document advocated for those who had been to China recently to self-monitor for 14 days, and that those exhibiting no symptoms after the 14-day period were able to return to their normal lives.

In late February, greater precautions were undertaken by different organizations to be prepared for the potential spread of the virus into Connecticut. On February 25, the University of New Haven suggested that all students in Italy should return to the United States. A laboratory in Rocky Hill was approved by the United States Centers for Disease Control to test for COVID-19.

On March 2, two suspected cases of coronavirus in Connecticut were confirmed to be negative.

March 24: Soldiers from the Connecticut Army National Guard's 102nd Infantry Regiment began distributing personal protective equipment to medical facility personnel at the New Britain Armory.

On March 16, the National Junior College Athletic Association also canceled the remainder of the winter seasons as well as the spring seasons.

Unemployment
Over 30,000 unemployment claims have been filed between Friday, March 13, and Tuesday, March 17 in Connecticut. Many of these unemployment claims have been associated with the laying-off of employees of businesses unable to afford to maintain their entire staff during the outbreak, as well as due to the closure of businesses reliant on public and social interactions such as bars and gyms.

Xenophobia and racism
In response to racism surrounding the COVID-19 pandemic, Connecticut governor Ned Lamont stated during a speech at the Connecticut Department of Public Health's laboratory in Rocky Hill, "there is no link between race or ethnicity and the spread of coronavirus. Viruses do not discriminate."

Education
Governor Ned Lamont signed an executive order requiring the closure of all Connecticut public schools on March 17 until May 20; it was eventually extended for the rest of the school year. Most public schools were already closed. March 13–14 Lamont also encouraged private schools and other non-public schools to follow the same schedule.
