Coronaviruses are very tiny germs that can make people sick. They are spread through coughing, sneezing, and touching people or things that have the virus on them. Coronaviruses can cause a number of different diseases, such as the common cold, influenza, and more recently, COVID-19. These diseases can have a range of symptoms, from mild to severe. The symptoms may include fever, a cough, and difficulty breathing, as well as other symptoms. To protect yourself from getting the coronavirus, it is important to wash your hands often, stay away from people who are sick and sick areas, and cover your mouth with your elbow when you sneeze or cough.
