How is typhus transmitted carried to humans?
Flea-borne typhus is spread to people through contact with infected fleas. Fleas become infected when they bite infected animals, such as rats, cats, or opossums. When an infected flea bites a person or animal, the bite breaks the skin, causing a wound.
What is transmitted via the louse?
When body lice infestation is long lasting, heavily bitten areas of the skin can become thickened and darkened, particularly in the mid-section of the body. Body lice are known to transmit disease (epidemic typhus, trench fever, and epidemic relapsing fever).
Can typhus be transmitted?
You can catch typhus if you’re bitten by infected lice, mites or fleas. These are often found on small animals like mice, rats, cats and squirrels. People can also carry them on their clothes, skin or hair.
What is the vector for typhus?
Transmission of epidemic typhus occurs by arthropod vectors. The primary vector in person-to-person transmission is the human body louse (Pediculus humanus corporis).
Is typhus caused by rats?
About This Disease. Murine typhus is a disease carried by rodents (rats, mice, mongoose) and spread to humans by fleas. It is caused by a bacteria called Rickettsia typhi.
What is the vector agent for typhus?
The arthropod vector of epidemic typhus is the body louse (Pediculus corporis). This is the only vector of the typhus group in which humans are the usual host. Rickettsia prowazekii, which is the etiologic agent of typhus, lives in the alimentary tract of the louse.
Do mice carry typhus?
Murine typhus is a disease carried by rodents (rats, mice, mongoose) and spread to humans by fleas. It is caused by a bacteria called Rickettsia typhi. The fleas can also live on other small mammals, including pets, such as cats and dogs. Once a flea is infected, it can spread the disease for the rest of its life.

What is louse borne typhus?
Epidemic/louse-borne typhus. 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.
How did typhus spread to North America?
It was carried to North America by the many Irish refugees who fled the famine. In Canada, the 1847 North American typhus epidemic killed more than 20,000 people, mainly Irish immigrants in fever sheds and other forms of quarantine, who had contracted the disease aboard coffin ships.
How do fleas spread typhus?
Fleas, mites, lice, and ticks are types of invertebrate animals known as arthropods. 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.
What is the cause of typhus?
Cause of typhus. 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.
