How can you spread this disease while not showing symptoms? If you aren't coughing or sneezing you're only releasing fluid by exhaling. When you exhale the moisture in your breath floats up into the air and quickly disperses, not landing on any surfaces like the thicker fluid from a cough or sneeze.

Also what happens during the 2-14 day incubation period? The virus just decides to take a break for a few days after entering a human body, then gets to work taking over cells?
