Coronavirus disease, also known as COVID-19, is a highly contagious respiratory illness caused by the SARS-CoV-2 virus. It first emerged in Wuhan, China in December 2019 and has since spread globally, resulting in a pandemic.
Symptoms of COVID-19 can range from mild to severe and may include fever, cough, and difficulty breathing. The virus primarily spreads through respiratory droplets when an infected person talks, coughs, or sneezes.
Prevention measures for COVID-19 include wearing a mask, washing hands frequently, and practicing physical distancing. Vaccines are also available to help prevent infection and reduce the severity of illness. Treatment for COVID-19 may include supportive care, such as oxygen therapy or mechanical ventilation, as well as antiviral medications.
It is important to stay informed about the latest guidance from public health authorities and to take necessary precautions to protect oneself and others from COVID-19.
