The Prevention and Treatment of Carbon Tetrachloride Intoxication

In the last ten years great advances have been made in the treatment of hookworm disease. These have been due largely to two factors: the campaign carried out by the International Health Board of the Rockefeller Foundation, making it possible to treat very large numbers of cases and to study the best methods of treatment, and the discovery in 1921 by Dr. Maurice C. Hall¹of the anthelmintic properties of carbon tetrachloride, which is relatively so harmless and so effective that it can be given to whole communities in which hookworm is prevalent, with the assurance that it will remove from 95 to 100 per cent of the hookworms harbored by infested individuals.
