Symptoms of epidemic typhus begin within 2 weeks after contact with infected body lice. Signs and symptoms may include:. Some people can remain infected, without symptoms, for years after they first get sick.
Rarely, these individuals can have a relapse in disease, called Brill-Zinsser disease, months or years following their first illness. The symptoms of Brill-Zinsser disease are similar to the original infection, but are usually milder than the initial illness.

Fleas poop when they feed. The poop also called flea dirt can then be rubbed into the bite wound or other wounds causing infection.
People can also breathe in infected flea dirt or rub it into their eyes. This bacteria is not spread from person to person. Flea-borne typhus occurs in tropical and subtropical climates around the world including areas of the United States southern California, Hawaii, and Texas.
Flea-borne typhus is a rare disease in the United States. Symptoms of flea-borne typhus begin within 2 weeks after contact with infected fleas or flea dirt. Brill-Zinsser disease is a mild form of epidemic typhus. It occurs when the bacteria become active again in a person who was previously infected.
It is more common in older adults. The early rash is a light rose color and fades when you press on it. Later, the rash becomes dull and red and does not fade. People with severe typhus may also develop small areas of bleeding into the skin.
Diagnosis is often based on a physical examination and detailed information about the symptoms. You may be asked if you recall being bit by fleas. If the health care provider suspects typhus, you will be started on medicines right away. Blood tests will be ordered to confirm the diagnosis.
Tetracycline taken by mouth can permanently stain teeth that are still forming. It is usually not prescribed for children until after all of their permanent teeth have grown. When arthropods carrying around rickettsial bacteria bite someone, they transmit the bacteria that causes typhus. Scratching the bite further opens the skin and allows the bacteria greater access to the bloodstream.
Once in the bloodstream, the bacteria continue to reproduce and grow. The type of typhus you are infected with depends on what bit you.
Arthropods are typically carriers of a typhus strain unique to their species. Typhus outbreaks usually only occur in developing countries or in regions of poverty, poor sanitation, and close human contact. Typhus is generally not a problem in the United States, but you may become infected while traveling abroad.
Typhus is not transmitted from person to person like a cold or the flu. There are three different types of typhus, and each type is caused by a different type of bacterium and transmitted by a different type of arthropod. This type is caused by Rickettsia prowazekii and carried by the body louse , and possibly by ticks as well. It can be found around the world, including in the United States, but is typically found in areas of high population and poor sanitation, where conditions promote lice infestation.
Alternatively known as murine typhus, this type is caused by Rickettsia typhi and is carried by the rat flea or cat flea. Endemic typhus can be found worldwide. It may be found among people in close contact with rats. Is it a fleabite? Symptoms and treatments ». This type is caused by Orientia tsutsugamushi and carried by mites in their larval stage when they are chiggers.
The louse, flea, tick , or mite becomes a carrier of the bacteria when they feed on the blood of an infected person epidemic typhus or an infected rodent any of the three typhus forms mentioned above. If you come in contact with these bacterium-carrying arthropods for example, by sleeping on bed sheets infested with lice , you can become infected in a couple ways.
