Typhus 1 Rickettsia prowazekii causes epidemic typhus, the more severe form, and is spread mainly by lice, although sylvatic typhus (also due to R. prowazekii) is found in the USA and associated with bites from the fleas of a flying squirrel.2  Rickettsia typhi causes endemic or murine typhus and is transmitted by fleas. Rickettsia typhi causes endemic or murine typhus and is transmitted by fleas. 2  The term endemic refers to the fact that there is an animal reservoir of disease maintaining the presence of typhus in a particular area. 3  Rickettsia felis is found in cats and has also been linked to endemic typhus.

typhus 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.urine typhus is a less common variety, also known as tabardillo and endemic, rat, or flea typhus. As indicated by the term murine, it is transmitted by rat or mouse fleas. The symptoms are like those of louse-borne typhus but are less severe, and recovery occurs sooner.

Is Typhus Contagious? Transmission of Typhus from Person to Person. Typhus is considered infectious but is not transmitted from person to person. 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. Other words for contagion include infection, infectiousness, transmission or transmissability.

What Is Equine Infectious Anemia (A.K.A. Swamp Fever)? Equine infectious anemia is a contagious illness that is not limited to horse populations in the United States, but is instead found around the globe.Commonly referred to as swamp fever, this disease is aptly named because it occurs most frequently in areas of heightened humidity as well as temperature.he transmission of the virus that causes equine infectious anemia has been known since the year 1904. It was then linked to pests which live on the lifeblood of the horses. Perhaps the most common culprit is the horsefly.

Typhus Occasionally, the bacteria may become dormant in infected cells, and years later, again begin to multiply (causing Brill-Zinsser disease). Generally, typhus follows an animal (rat, mouse) to vector (louse, flea) cycle. Humans are incidentally infected usually when the vectors come in close proximity to humans.
