I just got off the phone with my neurologist, who said that besides the fact we know this virus is susceptible to soap (thus the need for constant hand washing), there is also some indication it may be susceptible to heat that exceeds 130 degrees Fahrenheit. So place a towel around your heads, put your head above a bowl of steaming water and inhale through your nose. The theory is that the heat will kill anything that settled into your nasal tract before it can get to your lungs.
I don’t know what the CDC or WHO has to say about this, but it certainly could not hurt, makes sense, and is drug free. I know this will become a part of my daily routine.
