Serologic Evidence of Scrub Typhus in the Peruvian Amazon

Emerg Infect Dis. 2017 Aug;23(8):1389-1391. doi: 10.3201/eid2308.170050.


Using a large, passive, febrile surveillance program in Iquitos, Peru, we retrospectively tested human blood specimens for scrub typhus group orientiae by ELISA, immunofluorescence assay, and PCR. Of 1,124 participants, 60 (5.3%) were seropositive, and 1 showed evidence of recent active infection. Our serologic data indicate that scrub typhus is present in the Peruvian Amazon.
