COVID-19 is a respiratory illness caused by a new virus. The virus is spread from person to person through close contact, droplets from coughs or sneezes, and contact with surfaces infected by these droplets followed by touching the face or mouth. Symptoms of COVID-19 may include a cough, fever, tiredness, and difficulty breathing (in severe cases). Symptoms can develop between 1 and 14 days after infection. Approximately 80% of people will recover from the virus without the need for special treatment. Elderly people and people with underlying medical conditions are more vulnerable to serious illness.
