I believe this is true of most such viruses. The flu is also contagious the day before you show symptoms, then most contagious 5-7 days after [1]. [EDIT] Actually, it says as much in the graph in your article. [1] https://www.cdc.gov/flu/about/disease/spread.htm https://www.cdc.gov/flu/about/disease/spread.htm

  You're lying! The reference link says: > People with flu are most contagious in the first 3-4 days after their illness begins. Not "day before". Also the link says: > healthy adults may be able to infect others beginning 1 day before symptoms develop But not that it's most contagious then. Maybe it's like 100x less contagious then. Those two facts don't combine. It can be most contagious on day 3, for example. PS: And using common sense which often (though not always) helps -- the one coughs -- the more they are contagious. If there's no symptoms (cough), then it's probably less contagious.

    Mm, indeed I meant to say "also contagious" in the first part, not "most contagious," pardon me, I've edited to reflect. I mean, I did provide a link that said as much.

    The GP post can be incorrect without lying. Such accusations are not conducive to positive discussion, and run counter the the guidelines under which HN operates.
