More than 60 different diseases, some of which are fatal, are spread by ticks, chiggers, insects and other biting arthropods. These include malaria, Dengue (Broken Bone) Fever, West Nile Virus, Lyme Disease and others. The Army Combat Uniform with factory Permethrin treatment can, when worn with other measures, provide over 90 percent bite protection even after 50 washings. This will help protect Soldiers against these diseases. The ACU with Permethrin will be issued to Soldiers serving in the continental United States and elsewhere.
