Please note: Only a fraction of respiratory viruses is transmissible via aerosol. N95 respirators have been assumed to provide more complete protection against respiratory viruses in healthcare settings. Person-to-person spread is thought to come via respiratory droplets from an infected person. A cough or sneeze, as in influenza spread will transmit the virus. This novel coronavirus (just named yesterday) does not require more than the basic face mask and 6 feet of space to protect. Furthermore, it is believed to be contagious prior to an infected person developing a fever and signs of viral illness.
