ok all the media people pushing face masks should at least be truthful about which ones are effective in really protecting you from the WUHAN Virus. Telling people to wear scarves and homemade cloth masks is a false pretense. The only mask that is at all effective is the N95 one. All virus is a miroorganism and passes thru anything porous. Why do you think health care workers are getting sick. They are taking all the precautions.At least be truthful and let people decide, It will prevent coughs and sneezing so if your SICK and need to go out in the public them wear one.
