The risk of exposure to a tick carrying R. rickettsii is low.

A female tick can transmit R. rickettsii to her eggs in a process called transovarial transmission.

Rickettsiae are transmitted to a vertebrate host through saliva while a tick is feeding.

Once infected, the tick can carry the pathogen for life.

Some zoonotic diseases require a vector (e.g., a mosquito, tick, or mite) to be transmitted from the animal host to the human host.

Other tick species have been shown to be naturally infected with R. rickettsii or serve as experimental vectors in the laboratory.

Ticks can also become infected with R. rickettsii while feeding on blood from the host in either the larval or nymphal stage.

Less commonly, infections may occur following exposure to crushed tick tissues, fluids, or tick feces.

The life cycle of this tick may require up to three years for its completion.

This tick is the most commonly identified species responsible for transmitting R. rickettsii to humans.

After the tick develops into the next stage, the R. rickettsii may be transmitted to the second host during the feeding process.
