Disease, werner-his

Named for the german physician Heinrich Werner (who did not describe Werner's syndrome) and the Swiss physician Wilhelm his, Jr. (who did describe the bundle of his in the heart), this is a louse-borne disease first recognised in the trenches of world war i (and so called trench fever), again a major problem in the military in world war II, seen endemically in Mexico, N. Africa, E, Europe, and elsewhere. The cause, rochalimaea quintana, is an unusual rickettsia that multiplies in the gut of the body louse. Transmission to people can occur by rubbing infected louse feces into abraded (scuffed) skin or conjunctiva (whites of the eyes). Onset of symptoms is sudden, with high fever, headache, back and leg pain and a fleeting rash. Recovery takes a month or more. Relapses are common. Also called wolhynia fever, shin bone fever, quintan fever, five-day fever, Meuse fever, his-Werner disease.
