Louse-borne relapsing fever is more severe than the tick-borne variety. [citation needed] Louse-borne relapsing fever occurs in epidemics amid poor living conditions, famine, and war in the developing world. [6] It is currently prevalent in Ethiopia and Sudan. [citation needed] Mortality rate is 1% with treatment and 30–70% without treatment.
Human granulocytic anaplasmosis (HGA) is a tick-borne, infectious disease caused by Anaplasma phagocytophilum, an obligate intracellular bacterium that is typically transmitted to humans by ticks of the Ixodes ricinus species complex, including Ixodes scapularis and Ixodes pacificus in North America.

Tick-borne relapsing fever is transmitted through the bites of lice or soft-bodied ticks (genus Ornithodoros). [10] Each species of Borrelia is typically associated with a single tick species, with Borrelia duttoni being transmitted by O. moubata , and being responsible for the relapsing fever found in central, eastern, and southern Africa.
For comparison, while it takes a tick carrying Lyme disease nearly 24 hours to pass the infection on to a human host, a tick with POW can transfer the virus in as little as 15 minutes.
The soft tick Ornithodoros carries the species of Borellia that cause relapsing fever. [9] Another species, B. anserina, is carried by the soft tick Argas. [4] Inside the ticks, the bacteria grow in the midgut and then travel to the salivary glands to be transmitted to a new host. [21] Ticks can spread the bacteria to each other when co-feeding ...
The danger posed by ticks increases during the heat of summer.
