What is covid 19 disease? - តើជំងឺ covid 19 គឺជាអ្វី? Corona is a virus and it’s something we’re all talking about, it’s new for everyone. The virus causes a disease called Covid-19 or Covid-19. Most people are affected by the virus and can be fatal. The virus begins by infecting the upper respiratory tract, the passage from the nose to the larynx. The virus can spread to the lungs, making it difficult for people to breathe, and it can also cause pneumonia. The virus can enter your body through breathing through your eyes and mouth, so the best thing you can do to prevent it is to wash your hands regularly. Regularly and accurately for at least 20 seconds, and when coughing and sneezing, cover your mouth and nose with a tissue and avoid touching your face with your hands. កូរ៉ូណា គឺជា​ប្រភេទR
