Typhus fever is a serious illness caused by bacteria transmitted through fleas, lice, or ticks. Some common synonyms for typhus fever include epidemic typhus, murine typhus, and scrub typhus. Epidemic typhus, also known as louse-borne typhus, is spread by body lice and can lead to severe illness and even death. Murine typhus, also called flea-borne typhus, is transmitted by fleas and is typically milder than epidemic typhus. Scrub typhus, transmitted by mites, is a less common form of typhus that occurs in rural regions of Asia, Australia, and the Pacific Islands. Regardless of the type, treatment for typhus fever involves antibiotics and supportive care.
