Frequently Asked Questions (FAQs) Body lice can spread epidemic typhus, trench fever, and louse-borne relapsing fever. Although louse-borne (epidemic) typhus is no longer widespread, outbreaks of this disease still occur during times of war, civil unrest, natural or man-made disasters, and in prisons where people live together in unsanitary conditions.

relapsing fever In louse-borne relapsing fever (LBRF), lice acquire Borrelia from humans who are already infected. These lice can then go on to infect other humans. LBRF is said to be epidemic, as opposed to endemic, meaning that it can occur suddenly in large numbers in specific communities of people.

- The specific type of Rickettsia that causes the disease also varies, as does the specific insect that can pass the bacteria along. Epidemic typhus, which is sometimes called jail fever or louse-borne typhus, is caused by Rickettsia prowazekii, which is carried by body lice.When the lice feed on a human, they may simultaneously defecate. When the person scratches the bite, the feces (which carrys the bacteria) are scratched into the wound.lying squirrel typhus an acute infectious disease similar to epidemic typhus, occurring in the southeastern United States; it is caused by Rickettsia prowazekii and is transmitted by the fleas and lice of the flying squirrel.

- Types of typhus and carriers: 1  epidemic/louse-borne typhus (caused by Rickettsia prowazekii) carried by the body-louse. 2  murine typhus (caused by R. typhi) carried by the rat or cat flea.3  scrub typhus (caused by Orientia tsutsugamushi) carried by mites.yphus fevers are caused by the rickettsiae bacteria and transmitted by arthropod (e.g. flea, mite, tick) bites. When arthropods bite a victim, they leave the rickettsaie bacteria behind. Scratching the bite opens the skin to the bacteria, allowing them to enter the bloodstream.

Overview Head lice. Head lice are tiny insects that feed on blood from the human scalp. An infestation of head lice, called pediculosis capitis, most often affects children and usually results from the direct transfer of lice from the hair of one person to the hair of another. head lice infestation isn't a sign of poor personal hygiene or an unclean living environment. Head lice don't carry bacterial or viral infectious diseases. Over-the-counter and prescription medications are available to treat head lice.

Generally, a disease like this is caused by an infectious agent and not spread between people.Typhus, although infectious, is not a genetic disease. It is not caused by a defective or abnormal gene.ontagion and contagiousness refers to how easily the spread of Typhus is possible from one person to another.

- Disease. Pubic (crab) lice are not known to transmit any disease. Itching (pruritus) in the pubic and groin area is the most common symptom of pubic lice infestation.As with other lice infestations, intense itching leads to scratching which can cause sores and secondary bacterial infection of the skin.ubic lice on the head (eyelashes or eyebrows) of a child may be an indication of sexual exposure or abuse. Persons infested with pubic lice should be evaluated for other sexually transmitted diseases (STDs).

Yet half a century after his death, body lice remain the only species of louse taken seriously as a threat to human health, despite subsequent research backing Zinsser's findings.
