Not at all. Not pretending anything, it’s quite serious. If I’ve got it and I come in contact with a couple hundred people in the next couple days, I’m rapidly spreading it. Same with the thousands of others that may have it and are going to work tomorrow or will be in public. Until more gets shut down it’s not slowing anything down
Just how contagious do you think this is? Most estimates I've seen have placed the R0 (number of new people infected from each case) somewhere in the 2-3 range. Which fits the data I've seen, cases seem to double about every 6 days so that would be an average incubation period of about 6-9 days.
It's very easy for a lot of people's imagination to run wild and think everybody is spreading a virus to everyone they pass on the street but that's simply not possible. A virus that contagious would likely burn out very quickly.
If people are careful and limit contact, it is very possible people might only infect 1 or even 0 rather than 2 or 3. Any average R0 less than 1 and it goes away over time. But it's really important we not panic or just give up.
