No cases of yellow fever have developed in the Canal Zone or the cities of Colon and Panama from 1909 to 1922. A few cases arrived at the quarantine stations and some of these were transferred to Ancon Hospital (Now Gorgas Hospital) for better care and observation. It is only in fairly recent yrs. that laboratory methods have been developed that help in establishing a diagnosis of the disease. The mouse protection test is now available and the viscerotomy service has made it possible to collect more evidence of the presence of the disease. During Nov. and Dec, 1948, a few acute cases of yellow fever occurred in Panama e. of the Canal Zone and one case w. of the Canal Zone. Later another case appeared, on the Atlantic coast near the boundary of Costa Rica. The disease appeared a little later in Costa Rica in a moderate epidemic form on the Atlantic slope. A yellow fever service was organized in Panama in 1949 and as part of this service the Gorgas Mem. Lab. agreed to survey the arboreal forest mammals to determine the wild life reservoir of jungle yellow fever and later in the s. part of Mexico (State of Chiapas). The Panama survey was divided into studies made e. of the Canal Zone and w. of the Canal Zone. A collection of 201 mammals (chiefly monkeys) e. of the Canal Zone was tested by the mouse protection test and 104 were found to be positive. A collection of 224 animals was tested w. of the Canal Zone and 68 were found positive or 30.3%. The survey made in the State of Chiapas, Mexico in Mar. and Apr., 1951, was made on a collection of 77 monkeys taken in 2 localities. This collection was tested by the Gorgas Mem. Lab. and the Servicio Nacional de Febre Amarela in Rio de Janeiro. The reports from Brazil gave a positive rate of 12 % and from the Gorgas Mem. Lab. 12.5 % in one locality and 3.7 % in the other. There is a wild life reservoir of yellow fever throughout Panama and Southern Mexico. All industries using large labor forces in forested regions should vaccinate their employees. The primitive forest, where the larger spp. of monkeys live is disappearing, but the small spp. and the kinkajou will thrive in 2d growth or bush country. At the present time the howler monkey, the spider monkey and the white face monkey are the animals showing the highest rate of positives to the mouse test.
