What is the portal of exit of rocky mountain spotted fever?

Answer 1

The portal of exit for Rocky Mountain spotted fever (RMSF) primarily involves the bite of an infected tick, specifically the Dermacentor species. When the tick feeds on a host, it introduces the Rickettsia rickettsii bacteria into the bloodstream, which is how the pathogen exits the tick and enters the host. Additionally, the bacteria can also be present in the tick's saliva, aiding in its transmission during the feeding process. Therefore, the primary exit route is through the bite site during the tick's feeding.
