Generally speaking, when does a person with a cold become non-infectious?
For example. Let’s assume a seven-day illness. The first day, the person starts to display symptoms. The third day symptoms reach their peak. Symptoms decline for the next few days. When is it safe to be around other people? X days after symptoms start to decline? The day symptoms disappear? X days after symptoms disappear?
Full disclosure: Yes, I have a cold. But this is a general question about colds, and not specific to me. Just something I’ve always wondered.
