COVID-19 can cause fever, cough, congestion, fatigue, shortness of breath, headache, sore throat, nausea or vomiting, loss of smell or taste, and body aches. In some cases, COVID-19 develops into severe respiratory illness, which often is characterized by chest pain and extreme difficulty breathing that require hospitalization. Some hospitalized patients also develop neurological symptoms, such as severe fatigue and altered consciousness. Delirium, depression, and anxiety can complicate and prolong recovery.
