It's not really a couple of weeks at this point... it's just after the 6th or so. That's the end of incubation period for people who would have been infected before the Chinese govt. quarantined Wuhan. New infected after that point will be from person to person contact with infected travelers prior to the quarantine. That's when we'll find out how many people caught the virus that we don't know about, and therefore how many have been spreading it without knowing.
