*Zhong Nanshan* (a Chinese pulmonologist who discovered the SARS coronavirus in 2003) suggested simple ways to prevent Wuhan pneumonia:

It is recommended that you rinse your throat with light salt water before going to the hospital or other public places (and do the same after you return home). The method is as follows:

a) hold a mouthful of dilute salt water;
b) raise your head; let the salt water stay around your throat area
c) open your mouth slightly and exhale slowly, let air bubbling through the water in your throat and make a "ha" sound
d) spit out the salt water after a few seconds
e) repeat 3-5 times

Because viruses or bacteria lurk in the pharynx through the nasal passage, diluted salt water can kill them on the spot, thereby achieving the purpose of preventing infection. During SARS, I promoted and supervised this method among my students. As a result, none of our students in our class got cold, cough and fever.

This method is simple, effective, easy to do. But requires persevere.
