As gorillas are very closely related to humans, most diseases can be transmitted between the two species. Wherever gorillas live in close proximity to people, their intestines have been found to contain a considerably higher number of human parasites than are present in “wild” gorilla populations.



The most dangerous diseases are those against which gorillas have no antibodies. For example, respiratory diseases are a big problem for mountain gorillas. Scabies can also be dangerous. In the western lowland gorillas, Ebola has recently caused a particularly high number of casualties.



Respiratory diseases are caused by viruses; transmission mostly takes place through droplet infection during sneezing. This is why people who visit the gorillas are required to wear breathing masks in some national parks. The mites that cause scabies are usually transmitted to the gorillas by domestic animals that range close to gorilla habitat. In the case of Ebola, the path of transmission has not yet been fully determined. It is assumed that gorillas catch the disease when they eat fruit on which infected fruit bats have left traces of saliva or faeces.
