Personal protection is the most important single aspect of the control program against hemorrhagic fever and consists of personally applied insect repellent and impregnating the outer clothing by dipping it into a standard miticide, 1–17 dilution, at least once monthly or after every third washing, preferably at the time of laundering. Bulk laundry from line regiments and clothing from army shower points should be impregnated at quartermaster field laundries. When this service is not available to troops, impregnating should be done locally by hand dipping. It is obvious that the fewer the impregnating stations the more effective will be the program. The other phases of control—spraying outer covers of sleeping bags with 1–10 miticide, spraying 1% Lindane emulsion to tent and bunker floors and walls, and the rodent control program—all add to the completeness of the program.
Control of mites at best is difficult and, during military operations, personal protection against them plus limited environmental control against both mites and possible host reservoirs make a sound approach to reducing the number of non-effectives from this disease to a minimum.
