Does COVID-19 have a long “incubation period” because we don’t have any immunity to it?
This is a “makes sense to me” idea I merely thought of, and I have 0 medical expertise. So this is probably dumb, but now that I’ve thought of it I keep wondering whether it’s true.
My thinking is that the early symptom onset we feel when we get a cold or flu is partly down to our immune system responding, which causes inflammation etc. With the novel coronavirus, the immune system isn’t responding early on, and the infection itself will be in the slow ramp stage of its exponential growth, so the infection is already well established by the time you start to feel it.
