I am not sure if you read my comment through. I mentioned sick people being infectious, and urged the discussion to move towards how sick people infect others, and how long they are infectious.

I would love to learn more about how sick people transmit the disease, and when are they the most "infectious". I have heard something related to a period of few days before showing first symptoms, but I have yet to discover more indepth discussion around it.

For example, its pretty hard for me to undertand how you can be "very infectious" when you do not exhibit symptoms such as coughing or sneezing. Would love to learn more!
