I just watched video this morning from Dr. John Campbell on Youtube that presented pretty head scratching data out of Africa.
The gist is many of the more poor countries in Africa are showing high rated of SARS-CoV-2 in the population, but hardly anyone is getting really sick or dying. What makes it even more bizarre is South Africa is struggling with it on par with Europe, the Americas, and India.
The assumption was poor African countries with poor health systems would be ravaged by the pandemic, but it simply has not happened. Some theories:
- High exposure to other coronaviruses has created cross-immunity
- Exposure to Malaria and Dengue Fever might have created cross-immunity
- Lower median ages for most African countries
- High Vitamin D exposure
But none of these really seem to adequately answer the question as to why poor sub-Saharan countries in Africa are avoiding the scale of complications and death that more developed countries on other continents have. Again, testing has revealed high seroprevalence in the population, just not much damage coming from the infections.
Any of y'all have any ideas?
