Yeah, people who are making claims about social distancing, etc. are wildly leaping to conclusions. There are a number of more plausible / simpler alternatives

Yeah, people who are making claims about social distancing, etc. are wildly leaping to conclusions. There are a number of more plausible / simpler alternatives. For example: the innate immune system gets activated whenever you have an infection. This is the most primitive form of immunity that you have, and is blunt (fever, snot, generic immunoglobulins, etc.) but effective at warding off pathogens of any sort. It's why you don't often get two different upper respiratory infections at the same time.
