From the review of a book on pandemics

How pandemics shape social evolution “As Snowden discusses, by restricting the land available to people of colour, apartheid accelerated the growth of a migrant labour system that divided black families. It also encouraged new forms of social and sexual behaviour. Both developments, in turn, hastened the spread of AIDS once it arrived. Young men growing up away from their families, for instance, often developed standards of masculinity that promoted sexual conquest and violence; South Africa now has one of the highest rates of rape in the world (K. Naidoo S. Afr. Med. J. 103, 210–211; 2013). ” This seems to have parallels in some Indian sexual violence cases.
