The subject of typhus and its kindred diseases is no longer as simple as it appeared to be shortly after 1916 when the demonstration by Rocha-Lima, that typhus was caused by Rickettsia prowazeki, opened the door to further study. Widening knowledge .has made it evident that typhus or typhus-like diseases occur almost everywhere between the polar circles. These diseases are found under widely varied climatic conditions and in very different racial and social elements of humanity, Moreover, while classical typhus has a clear clinical picture, strains of Rickettsiae vary from one locale to another, even when solely borne from man to man by the louse. The typhus-like diseases, carried by a variety of arthropod vectors, make the study even more complex.
All typhus-like fevers have certain features in common. Each is transmitted by an arthropod, and the portal of entry into man is always the skin. Infection may or may not be marked by a primary ulceration of the skin according to the type of disease. The body is covered .more or less completely with a macular or papular rash. High fever appears suddenly at the onset of the disease, persists for IO to 14 days, and as suddenly subsides. Death rates vary with local conditions and specific strains of Rickettsiae.
