Captured in an unidentified location in China, this image depicts a group of Chinese epidemiologists, who were in the process of collecting data in the form of specimens, during an epidemiologic rickettsial investigation. These field workers were dressed in personal protective equipment (PPE), which covered their heads and bodies, in order to protect them from the possibility of tick bites, and an ensuing rickettsial disease.
“Rickettsial infections are caused by a variety of bacteria from the genera Rickettsia, Orientia, Ehrlichia, Neorickettsia, Neoehrlichia, and Anaplasma. Rickettsia spp. are classically divided into the typhus group, and spotted fever group (SFG). Orientia spp. make up the scrub typhus group. The rickettsial pathogens most likely to be encountered during travel outside the United States include R. africae (African tick-bite fever), R. conorii (Mediterranean spotted fever), R. rickettsii (known as both Rocky Mountain spotted fever and Brazilian spotted fever), O. tsutsugamushi (scrub typhus), and R. typhi (murine typhus).”
