Does anyone have thoughts on why there are so few documented reinfections if the risk is only cut by 84%? For instance this tracker only has 71 cases: https://bnonews.com/index.php/2020/08/covid-19-reinfection-tracker/ https://bnonews.com/index.php/2020/08/covid-19-reinfection-t... If it's that subsequent cases are much less severe then the 84% figure may be significantly understating the protective effect of natural immunity.

Perhaps a localized form of herd immunity? If people are getting it mostly from close contacts, maybe it already ripped through these little populations (families, small workplaces, etc.) pretty well.

It could be that the body is able to fight off the infection better, so they only have mild symptoms. Maybe they don't even know they have it again. The data in this study was based on health care workers who were tested every 2 to 4 weeks (i.e. not just when they felt really sick).
