Symptoms of COVID-19 can range from mild to severe, and may include fever, cough, difficulty breathing, and loss of taste or smell. The virus is primarily spread through respiratory droplets when an infected person talks, coughs, or sneezes. Prevention measures include wearing masks, social distancing, frequent hand washing, and vaccination. Treatment options include antiviral medications, oxygen therapy, and supportive care. The COVID-19 pandemic has had a profound impact on global health, economies, and societies.
