Knowledge is key to reducing the risk of infection from 2019-nCoV. The information included here is valuable, however developments are made constantly so it is good to monitor official health channels such as the CDC.
Practicing good infection prevention practices, such as frequent hand washing, is also important especially in public buildings. These practices also include; properly cleaning and disinfecting surfaces, respiratory hygiene and avoiding close contact with individuals. Most practices discussed in the media do NOT protect the individual using the practices, but rather protect others in the instance the person is infected. For example, using a mask does prevent airborne droplets from spreading if the individual wearing the mask coughs or sneezes, however the coronavirus is small enough to enter through the mask to the wearer. Properly cleaning and disinfecting surfaces may be one of the only truly preventative measures available.
