Schistosomiasis.

A film made by a behind the scenes army unit involved in sanitation, rubbish and disease control especially with relation to preventing mosquito bourne infections such as malaria.The film appears incomplete and some scenes may be out of sequence although it does have some interesting sequences. It starts with Tai Po Orphanage and sewage disposal at Car Nicobar (an Indian island). There are helpful intertitles throughout ('mosquitoes can breed in the most obscure streams') with illustrative footage. Interestingly the film points not only to poor practice in the local population but also there is a scene of somewhat tidier rubbish of a large pile of boxes discarded by Americans. Diseases mentioned in the film include ankylostomiasis (hookworm) and the dangers presented by scorpions in the desert.
