[FRIAM] covid question

[Prof David West]

Given that 23-30 percent (US estimated numbers) up to 50 percent (Iceland reported numbers) of Covid positives are asymptomatic:

1) if you have the disease, but do not show symptoms, do you still develop an immunity after some period of time?

2) If a pregnant woman recovers from the disease, is her immunity passed along to the fetus?

3) Will a woman who recovers and has immunity, pass that immunity along to any future conceptions?

4) If asymptomatic cases do develop immunity, "herd immunity" will be attained much faster than projected. But what is the trade-off between the number of people who might be infected by an asymptomatic — and what is the window of time when the person is an infectious agent — and the contribution to herd immunity? Not expressing this last question very eloquently, but hope point is clear.
