Coronavirus is a type of virus that can cause illness in humans and animals. The most well-known strain, called SARS-CoV-2, emerged in late 2019 and led to the global pandemic known as COVID-19. Symptoms of this disease can range from mild, like a cough or fever, to severe, requiring hospitalization. To prevent the spread of COVID-19, health experts recommend practices such as wearing masks, washing hands frequently, and getting vaccinated. Vaccines have been developed to help protect people from severe illness and reduce the spread of the virus. Staying informed and following guidelines is essential for keeping communities safe.
