During my undergrad studies in sociology I came across such theories. It's a bit hazy now but memories and thoughts about illness came flooding back. As an African, many illnesses and general misfortune in life is seen as either witchcraft or upset ancestors. As primitive as it may sound, these notions still hold fast today amongst young people too. I feel like researching this topic again...
