TROPICAL MEDICINE

1. The first half of the 20^th century witnessed the virtual conquest of three of the major diseases of the tropics: malaria, yellow fever, and leprosy. At the turn of the century, as for the preceding two centuries, quinine was the only known drug to have any appreciable effect on malaria. With the increasing development of tropical countries and rising standards of public health, it became obvious that quinine was not completely satisfactory. Intensive research between World Wars I and II indicated that several synthetic compounds were more effective.

2. The first of these to become available, in 1934, was quinacrine (known as mepacrine, Atabrine, or Atebrin). In World War II it fulfilled the highest expectations and helped to reduce disease among Allied troops in Africa, Southeast Asia, and the Far East. A number of other effective antimalarial drugs subsequently became available, the insecticide DDT among them. The lethal effect of DDT on the mosquito, its relative cheapness, and its ease of use on a widespread scale provided an intensive world-wide campaign, sponsored by the World Health Organisation, bringing malaria under control.

3. Yellow fever is another mosquito-transmitted disease, and the prophylactic value of modern insecticides in its control was almost as great as in the case of malaria. The forest reservoirs of the virus present a more difficult problem, but the combined use of immunisation and insecticides did much to bring this disease under control.

4. Until the 1940s the only drugs available for treating leprosy were the chaulmoogra oils and their derivatives. These, though helpful, were far from satisfactory. In the 1940s the group of drugs known as the sulfones appeared, and it soon became apparent that they were infinitely better than any other group of drugs in the treatment of leprosy. Several other drugs later proved promising. Although there is as yet no known cure for leprosy, the outlook has so changed that there are good grounds for believing that this age-old scourge can be brought under control
