Black people have resistive powers to Cryptococcosis, on average four times stronger than white people
“Despite that, it reproduces more slowly in hot surroundings as opposed to the cooler ones, and although it infects White people four times more easily on average than Black people, it was discovered on average six times more frequently in Aids patients from Zaire than patients in the USA.”
The causing agent of the highly rare cryptococcosis is the Cryptococcus neoformans fungus. The type, which occurs in nature, only reproduces at temperatures lower than the body temperature and does not grow in nerve-tissue. Other types, no longer grow at temperatures above 37 degrees Celsius.
