It's far from clear that having it actually provides reliable immunization.

I guess it provide immunization because it's very similar to what happens with a cold, but IANAMD. And this guy "Dr. Anthony Fauci" agree with me https://www.uchealth.org/today/what-you-should-know-about-co... (I'd like to have a direct citation.)

The main problem is that a small amount of the 40%-60% (I'd prefer more, like 70%) of the population will have complications (because they have an undiscover heart problem? they lie in the interview? bad luck?). And some of them will die (perhaps even for unrelated problem). And it doesn't matter how much paperwork they signed, the family will sue you and the press will fall over you.

(And probably the 40%-60% (70%) will not include children and it will propagate in schools, and also not include old people and it will propagate in geriatrics.)

I think I remembered this report about people potentially getting infected repeatedly: https://www.businessinsider.com/wuhan-coronavirus-risk-of-re...

It is strange. Is there more published information about the tourist guide? Perhaps it's a very rare case because she had other health problems.

Perhaps 99% of the people get enough immunity. Vaccines don't have a 100% of immunity protection neither.

The video linked in the article doesn't add much more information. Note that the written description says

> So, they need to prevent infection by increasing their physical activity, says Chinese expert.

that doesn't make any sense, but the translation in the video says

> cured patients should enhance their own health safeguards

Edit: I found https://globalnews.ca/news/6623287/coronavirus-multiple-infe... and https://www.reuters.com/article/us-china-health-japan/japane... . It's not very clear, but it looks like a continuation of the first infection after a few week of no symptoms. Anyway, another reason not to infect 50% of the population on purpose.
