Seroprevalence of chikungunya virus among military personnel in Papua New Guinea, 2019.

ABSTRACT:

Objectives

The first outbreak of chikungunya virus (CHIKV) was reported in West Sepik, Papua New Guinea (PNG) in June 2012, and spread rapidly throughout PNG. CHIKV imported from PNG to Queensland has been reported occasionally, but transmission of CHIKV in PNG remains unclear due to the lack of testing capability. This study investigated the degree of CHIKV exposure among PNG military personnel (PNGMP) in 2019, 7 years after its first emergence.

Methods

Sera of 204 PNGMP recruited in April 2019 was tested for the presence of anti-CHIKV immunoglobulin G (IgG) antibodies using a commercially available IgG detection kit, and anti-CHIKV neutralizing antibodies against a CHIKV Reunion strain using a neutralizing assay.

Results

Anti-CHIKV seropositivity of the sera was 47%
