COVID-19 is a highly infectious respiratory illness caused by the novel coronavirus, SARS-CoV-2. It was first identified in Wuhan, China in December 2019 and has since spread globally, resulting in a pandemic. Symptoms of COVID-19 can range from mild to severe and may include fever, cough, fatigue, and difficulty breathing. The virus is primarily spread through respiratory droplets when an infected person talks, coughs, or sneezes. Effective measures to prevent the spread of the virus include wearing a mask, social distancing, frequent hand washing, and vaccination.
