What I’ve read is that the incubation period is 14 days, that the virus can be transmitted without symptoms, and 1/2 of 10 million people in Wuhan (the epicenter) had already left the city before the quarantine. Given that scenario, it’s easy to see how this virus could spread worldwide quickly and there is pressure on government health organizations to not promote panic and therefore drive down the markets. If you’re traveling, N95 masks are recommended, and perhaps safety that wrap around or have shields. It transmits through any exposed mucous membrane.
