Instructions from the American family physician about the disease caused by Corona virus


  1. Droplets carrying Corona virus are quite large so it can be filtered by any regular mask (not just N95). However, when an infected person sneezes into the environment, the droplet (containing virus) can shoot up to 3m (about 10 feet) away and float in the air before falling to the ground.
  2. When dropped on a metal surface, the virus will live for at least 12 hours. So always remember, if you meet any metal surfaces, wash your hands with soap thoroughly.
  3. Virus can remain active on cloth for 6-12 hours. Regular washing powder can also kill the virus. For winter clothes which you can’t wash everyday, you can dry them in the sun to kill the virus.


Symptoms of corona-virus pneumonia:


  1. The virus will first cause inflammation of the upper respiratory tract, typically sore throat, so the throat will feel painful, dry lasting from 3 to 4 days.
  2. The virus then fuses into the nasal passages and drips into the trachea, invading the lungs, causing pneumonia. This process will take 5 to 6 days.
  3. When pneumonia occurs, the typical symptoms appear as high fever and shortness of breath. At this point, your nasal congestion will not be the same as the common cold or symptoms of allergic rhinitis, and you will feel as if you have a stuffy or drowned nose. If any of the above symptoms appeared, seek medical attention immediately.


Precautionary measures:


  1. The most common form of corona virus infection is by touching things in public places, so wash your hands often. Viruses can only live on your hands for 5-10 minutes, but in those 5-10 minutes there are many activities that can happen (you can accidentally rub your eyes or pick your nose, etc.), these activities allow the virus enter our body.
  2. In addition to regular handwashing, rinse your mouth with a pasteurized mouthwash to remove or minimize the virus while it is still in your throat (before it enters your lungs).
  3. Take care of yourself and don’t forget to drink lots of water!
