EFFECT OF SEASON AND DUST CONTROL ON COCCIDIOIDOMYCOSIS

A complete description of the activities of the Commission on Epidemiological Survey of the Board for the Investigation of Epidemic Diseases, Preventive Medicine Service, will be presented in the Surgeon General's History of World War II. It may be mentioned here that a general consultative service was provided, together with standardized coccidioidin and facilities for serologic tests and Coccidioides identification. In conjunction with the Army Air Forces, a detailed epidemiologic investigation was carried out in four army air fields in the San Joaquin Valley, California (fig. 1). These investigations began in July 1941 at Minter and Gardner fields in Kern County, in February 1942 at Merced Army Air Field in Merced County and in March 1942 at Lemoore Army Air Field in Kings County. They continued until three of the fields closed, Gardner in March 1945, Lemoore in October 1945 and Minter in February 1946. On July 1, 1945, when

NASOPHARYNX IN AN EPIDEMIC OF STREPTOCOCCIC INFECTION

THE RECENT epidemic of throat infection with group A, type 17, beta hemolytic streptococcus at Amarillo Army Air Field, Texas, presented interesting nasopharyngeal findings as seen with the nasopharyngoscope. A brief description of the ear, nose and throat complications that occurred in the epidemic is essential for evaluation of the nasopharyngeal study. The offending organism was almost completely resistant to sulfonamide compounds but was sensitive to penicillin. The infections with the A 17 streptococcus flourished in spite of prophylactic treatment with sulfadiazine of all personnel on the field. Prior to and during the epidemic the sulfadiazine prophylaxis program reduced infections by other strains of streptococcus to near zero. CLINICAL PICTURE During the epidemic most of the patients with throat cultures positive for the A 17 streptococcus who were admitted to the hospital had severe respiratory infections or sore throats. Many of them had scarlet fever. The otitis media, the sinusitis

Observations on the Abatement of Pest Mosquitoes with DDT Residual Sprays

During the investigations on the use of DDT (1-trichloro2,2-bis (p-chlorophenyl) ethane) for the control of mosquitoes, which were conducted in the vicinity of the Stuttgart Army Air Field at Stuttgart, Ark., in the summer of 1944, observations were made on the value of DDT residual sprays as a method of abating the nuisance of pest mosquitoes, such as the Psorophora spp. Studies by Gahan et al. (1, 2) had shown that these sprays were effective against Anopheles quadrimaculatus Say and other mosquitoes when applied to their diurnal resting places. As a result of the alternate drying and reflooding of the surrounding rice fields, enormous numbers of Psorophora mosquitoes invaded the cantonment area of the Stuttgart Army Air Field during the summer of 1944. The annoyance was so great that it became necessary to resort to daily treatment of all halls and corridors in the hospital building by power spraying of regulation Army issue insecticide containing Thanite (a thiocyanate). This situation was undesirable because it disrupted the regular hospital routine and tied up manpower and equipment needed for other mosquito-control work, and because of the rather disagreeable odor produced by the spray. In July a 10 per cent DDT emulsion was applied to the screens on all entranceways and windows with an ordinary decontamination-type spray cylinder. This spray was made from a basic concentrate consisting of 25 per cent of DDT, 7 per cent of Triton X-100 (an aralkyl polyether alcohol), and 68 per cent of xylene. (Less than 2 gallons of liquid were used to treat
