I thought the incubation period was close to 20 days.
I think the First Guy arrived on Sept 20.
He came in contact with someone, and now, about 10 days later, the second person is in isolation and being tested? Are they showing symptoms? In 10 days?
Why don't I believe anything anyone says about this disease?
Per CDC yesterday, the period of being contagious can be between 2 day and 3 weeks.
Some say it cannot be transmitted unless/until the patient shows symptons. Others seem to disagree. Their symptoms can be mild as cold-like or flu-like. They may even appear to get better and then get worse.
