Burden of Submicroscopic Plasmodium Infections and Detection of kelch13 Mutant Parasites in Military and Civilian Populations in Papua New Guinea.

Malaria remains a major public health problem in Papua New Guinea (PNG) and an important force health protection issue for both PNG and Australian Defence Forces. To investigate the malaria burden in the military and civilians residing on military bases, a cross-sectional survey was conducted in April 2019 at three military bases in Wewak, Manus Island, and Vanimo, PNG. A total of 1,041 participants were enrolled; 235 military personnel from three bases and 806 civilians from Wewak and Vanimo.

A Health Survey Revealing Prevalence of Vector-Borne Diseases and Tuberculosis in Papua New Guinea Defence Force Personnel and Families.

The Papua New Guinean Defence Force (PNGDF) and the Australian Defence Force (ADF) work and train closely. Infectious diseases pose a health threat to both forces, but recent knowledge about the risk at military bases in Papua New Guinea is limited. To improve understanding, a collaborative cross-sectional survey was conducted (March-April 2019) at Lombrum Naval base (Manus province) and Moem Army barracks (Wewak, East Sepik province) plus its Vanimo outpost (Sandaun province).

Prevalence of Barmah Forest Virus, Chikungunya Virus and Ross River Virus Antibodies among Papua New Guinea Military Personnel before 2019.

Barmah Forest virus (BFV), Chikungunya virus (CHIKV) and Ross River virus (RRV) belong to the genus of the family All three virus infections have been reported in Papua New Guinea (PNG) previously, but the exact prevalence and distribution of these three alphaviruses in PNG has not been established. Sera collected from 204 PNG Military Personnel (PNGMP) study participants in April 2019 was tested for the presence of anti-BFV, anti-CHIKV and anti-RRV immunoglobulin G (IgG) antibodies using commercially available enzyme-linked immunosorbent assay (ELISA) IgG detection kits, as well as for specific neutralizing antibodies (NAb) against individual viruses. Overall, sero-positivity of the sera was anti-BFV IgG 12.

Serological evidence of possible high levels of undetected transmission of Zika virus among Papua New Guinea military personnel, 2019.

Objectives: The Papua New Guinea (PNG) Health Department retrospectively reported six cases of Zika virus (ZIKV) from a cohort of febrile patients during outbreaks of dengue and malaria in 2016. However, the transmission of ZIKV remains unclear due to lack of testing capability. This study aimed to determine the level of immunity to ZIKV among PNG military personnel (PNGMP) in 2019.

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

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.
