Extraordinary advice from Japanese doctors dealing with COVID 19 cases:
Every person should take care that their mouth and throat are always moist. Never dry. Have a sip of water every 15 minutes (and more often).
Why?
Even if the virus reaches the oral cavity, water or other fluid will expel it through the esophagus into the stomach. When the virus reaches it, it will kill the acid from the stomach.
The virus through the nitrogen can enter the lungs if you do not drink water regularly. That is dangerous then.
