Only if the virus doesn't beat you first. In the case of COVID-19, large portions of nursing home populations won't have the opportunity to develop herd immunity if they die en masse from a point source introduction. One of the most frustrating things about this disparity in clinical disease/mortality is how young carriers of the agent are entirely unaffected while the most susceptible die with alarming alacrity. Nasty wicked problem.
Did you see Switzerland's studies were children can not carry enough of the virus to actually pass it on someone else?
Although studies may exist, I know of two cases among friends here in London where children did pass it on to adults, their parents. In one, our good friend, the one and a half year old toddler had a mild cough and a moderate temperature, much like a cold. She then caught it and because her brother is a doctor, got a test immediately, which was positive. She's in her late 30s and recovered after some scary days, but nothing that made her go to hospital.
I've be vey interesting to read the Swiss study of course, since I've got one and another on the way, and the 3 yr old will be heading back to nursery soon. There is no distancing of under fives.
I understand your concern, but how is it known the toddler caught the illness first or that they weren't infected by different sources.
This is from April 20th https://patient.info/news-and-features/ ... -they-last :
It is not always possible to know when people were first infected, especially if they may have received several 'doses' of virus.
There seems to be significant variation in the length of time it takes people to develop symptoms.
Some countries only test (and confirm) coronavirus in people with severe infection, and it's not known if the incubation period for people with critical/severe/moderate/mild infection is different.
It's thought that many people do not develop symptoms (they are 'asymptomatic') so there are no symptoms to count back from.
However, one study has looked at confirmed cases from 50 provinces, regions and countries outside Wuhan, where it was possible to identify a single source of infection. They found that:
The median incubation period (half of all cases occur before this time and half after) was 5.1 days.
97.5% of people who develop symptoms will have got them within 11.5 days.

The idea of getting several doses of the virus from different sources seems to have merit.
I seriously question data and numbers provided by China (and Pennsylvania!) and perhaps these doctors do to, and the study is accurate.
