How does typhus spread from person to person?

Answer 1

A louse becomes infected with typhus by taking a blood meal from a fever-ridden human. Once in the louse's gut, the rickettsiae reproduce to such enormous numbers that they cause cells in the insect's gut to rupture. The rickettsiae then are present in the feces of the louse. Humans become infected by rubbing or scratching the lice feces into their skin or into their mucous membranes.

Answer 2

Typhus is a disease caused by bacteria carried by some ticks and lice. They are spread by the bites of these creatures. There are many types, and Tick bite fever is probably the most well known name.

Typhus should not be confused with typhoid fever, caused by Salmonella bacteria.

How is typhus transmitted?

Humans are the only reservoir and are responsible for maintaining the infection during inter-epidemic periods. Outbreaks occur in colder areas where people live in crowded, unhygienic, louse-infested conditions. Milder symptoms of louse-borne typhus can occur years after the primary attack (Brill-Zinsser disease).

The disease is not directly transmitted from person to person. Patients are infective for lice during the febrile illness and possibly for two to three days after the temperature returns to normal. Infected lice pass rickettsiae in their faeces within two to six days after the blood meal; it is infective earlier if crushed. The louse invariably dies within two weeks after infection; rickettsiae may remain viable in the dead louse for weeks.

Susceptibility is general. One attack usually confers long-lasting immunity.

Risk for Travelers

Endemic typhus occurs often in people frequenting rat-infested buildings and houses in harbor or riverine areas. Foci of epidemic typhus exist in impoverished and dislocated populations in the highlands of some parts of Africa and South America, but travelers are rarely at risk of acquiring lice and disease.

Scrub typhus and tick typhus occur in people who engage in occupational or recreational behaviors that bring them inadvertently in contact with mite- or tick-infested habitats that harbor the rodent hosts of these arthropods. Tick typhus infections, often called spotted fevers, occur occasionally in travelers who spend time in nature trekking or camping, or on safari.

Answer 5

Typhoid is a bacterial disease, which spreads through water and spoiled food from an infected person. People need to drink fresh water or boiled water to prevent this..
