Abstract
ACCORDING to the Journal of the American Medical Association of January 10, owing to perfection of control methods initiated by Gorgas and Oswaldo Cruz, there have been no reports of yellow fever in Brazil or in the whole western hemisphere during 1941 or in the previous three years. Attention now centres on jungle yellow fever, which differs from urban yellow fever in that it is not transmitted by Aedes œgypti. Risk of yellow fever, however, will remain so long as the jungle type persists. It is no longer enough to accept clinical opinion, however experienced, for the diagnosis of yellow fever, but laboratory information by viscerotomy and protection tests is necessary. Vaccination has been carried out on a large scale with satisfactory results. The International Health Board of the Rockefeller Foundation continues to co-operate in the epidemiological and laboratory studies of the disease and in the preparation of vaccine.
