Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), is a single-stranded RNA virus that belongs to the large family Coronaviridae.

COVID-19 was declared a pandemic in March 2020. The COVID-19 pandemic has caused substantial morbidity and mortality, as well as social and economic disruption worldwide.

SARS-CoV-2 is transmitted from person-to-person by airborne particles and droplets. Infection from contaminated surfaces or objects is also possible but a less common source of illness. People with COVID-19 can be infectious from 1–2 days before, and up to 8–10 days after, symptoms begin.

Symptoms of COVID-19 may include fever, sore throat, congestion, cough, headache, body aches, fatigue, and/or loss of taste and smell. Severe disease may include pneumonia, cardiac complications, neurologic complications, and/or blood clotting problems. Risk of severe COVID-19 illness or death is higher in older persons, patients who are immunocompromised, or persons who have other underlying medical conditions.

Vaccines to prevent COVID-19 became available in December 2020. COVID-19 vaccine recommendations change over time, as vaccines are updated to better target evolving variants of SARS-CoV-2 viruses.

Note: FDA and CDC have approved and recommended updated 2024-2025 COVID-19 vaccine formulation. Older formulations of COVID-19 vaccines are no longer authorized for use in the United States.
