Why are there so many "viruses" in Africa?

Africa has many very powerful epidemics. Why do infectious diseases such as AIDS, Ebola, and dengue fever occur? Why is Africa the cause of this epidemic? The first is climate factors. Most of Africa belongs to humid areas of tropical rain forests. The dense tropical rain forests contain huge viruses and bacteria.

Secondly, most sanitary conditions in Africa are unsatisfactory. Except for some cities in South Africa, most cities are almost the same as "dirty, with garbage everywhere, mosquitoes raging, and flies dancing." Statistics show that Africa accounts for a quarter of the global disease burden, but only 3% of health workers have the disease. Poor sanitation does not end there, and the careers of local health workers are unattractive. Medical staff are paid very low wages, so you will have to bear many occupational risks, such as getting infected. Many doctors choose to travel to other countries in search of better working conditions, occupational safety and higher wages.

Third, the eating habits of wild animals greatly increase the possibility of viruses spreading from wild animal hosts to human hosts and causing new epidemics. In the case of Labrador, the Ebola virus first spread from animals to humans in the rainforest when humans came into contact with Ebola-infected blood, body fluids, or dead animals. People in some parts of Africa have access to wild animals such as monkeys or bats, which some use for food and are susceptible to pathogens such as Ebola during the processing of animal carcasses. After the virus breaks through the barrier between humans and animals, human-to-human transmission is through the blood and body fluids of patients, and contact with corpses caused by Ebola virus is very dangerous.

In countries with severe epidemics, the cremation of corpses is inconsistent with local traditional culture, and health experts believe that the burial process will promote the spread of the virus. In some parts of Africa, before the deceased is buried, their loved ones are thoroughly cleaned, and they must suck out any remaining urine and feces from their bodies.
