In Haiti, where still in 1981, this protozoan had not appeared, 21 out of 144 children under six months were affected by cryptosporidiosis in 1986. 19 out of 21 had been given the dried milk and only two children were breastfed. In the same year, it affected kindergartens in Cuba.
In Costa Rica, the children who went down were those fed with the dried milk. The creature had already reared its head in 1983 in Liberia and infected 5.9% of all children.
A pre-condition for their contact with the agent had been dried-milk feeds and living in a non-Islamic (i.e. mainly Christian) environment.
In Kigali, Rwanda, 10% of those children included in a study in 1983/1984, were suffering from diarrhea by Cryptosporidia, whilst the rate in Kampala, Uganda, was 25%. The agents must have been transmitted in food, to a certain extent at least.
Their appearance was described especially in the USA kindergartens in Georgia, Pennsylvania, Michigan, California, New Mexico, and Florida. Wherever they appeared, children infected in particular.
For South Africa, with the cooperation of a military officer, it was maintained in 1981 that Cryptosporidia occurred in among calves.
From 1985, Cryptosporidia-infections were then also reported among black South African children. This information, especially from Natal in South Africa, leads one to conclude that Cryptosporidia-infections were systematically spread.
In 1977, 1980, and 1983, for example, no such agents were found there.
In Haiti, Cryptosporidiosis occurred in 46% of Aids patients, in the USA, and among 3.3% in Kinshasa, Congo, among 8% or 30% from among the diarrhea-Aids patients in the Mama Yemo Hospital. In Uganda, it occurred in 48% of slim-disease patients and in Zambia, among 35% of Aids patients.
