Abstract
THE March issue of the Boletin de la Oficina Sanitaria Panamericana contains reports concerning Rocky Mountain spotted fever and the typhus group from five members of the Panamerican Sanitary Bureau Committee on Typhus, namely, Dr. Otávio de Magalhães of Brazil, Dr. L. Pãtino-Camago of Colombia, Dr. A. Recco of Cuba, Dr. C. G. Hidalgo of Ecuador and Dr. G. Varela of Mexico. There were, in all, 791 cases of Rocky Mountain spotted fever and 9,625 cases of the typhus group. Brazil reported 663 cases of spotted fever in the fourteen years 1929–42, occurring in thirty-six localities of three States (Rio de Janeiro, Minas Gerais and São Paulo), but the report was admittedly incomplete and consisted only of the severe forms of the disease. In Columbia there were 128 cases of Rocky Mountain spotted fever during 1934–43 in seven localities in two departments. With regard, to typhus fever (type not specified), except for Cuba where all the cases were of the murine type, Brazil reported four cases in 1941, Colombia 882 cases in 1942 and the first quarter of 1943 with a case fatality of 10–17·4 per cent in hospital cases. In Mexico there were 8,198 cases of typhus during 1938–42, with 750 in Mexico City, and a case mortality of 14 per cent. In Ecuador there were 517 cases of Rocky Mountain fever and 18 of typhus.
