Divergent Barmah Forest Virus from Papua New Guinea.

We report a case of Barmah Forest virus infection in a child from Central Province, Papua New Guinea, who had no previous travel history. Genomic characterization of the virus showed divergent origin compared with viruses previously detected, supporting the hypothesis that the range of Barmah Forest virus extends beyond Australia.

Detection of enteric viral and bacterial pathogens associated with paediatric diarrhoea in Goroka, Papua New Guinea.

Objectives: The aim of this study was to investigate the viral and bacterial causes of acute watery diarrhoea in hospitalized children in Papua New Guinea.

Methods: A retrospective analysis was conducted on stool samples collected from 199 children (age <5 years) admitted to the paediatric ward of Goroka General Hospital from August 2009 through November 2010. A large range of viral and bacterial enteric pathogens were targeted using real-time PCR/RT-PCR assays.

An investigation into febrile illnesses of unknown aetiology in Wipim, Papua New Guinea.

In Papua New Guinea the aetiology of febrile illnesses remains poorly characterized, mostly due to poor diagnostic facilities and the inaccessibility of much of the rural areas of the country. We investigated the aetiological agents of febrile illnesses for 136 people presenting to Wipim Health Centre in Western Province, Papua New Guinea. Arboviral and rickettsial real-time polymerase chain reaction (PCR) assays, malaria blood smears and a malaria PCR test were used to identify pathogens associated with a history of fever.

Outbreak of chikungunya virus infection, Vanimo, Papua New Guinea.

In June 2012, health authorities in Papua New Guinea detected an increase in febrile illnesses in Vanimo. Chikungunya virus of the Eastern/Central/Southern African genotype harboring the E1:A226V mutation was identified. This ongoing outbreak has spread to ≥8 other provinces and has had a harmful effect on public health.

Arboviruses of human health significance in Papua New Guinea.

Arboviruses (arthropod-borne viruses) are important emerging pathogens in many tropical and developing countries of the world. The Southeast Asian and Western Pacific regions have recently experienced large outbreaks of dengue, Japanese encephalitis and chikungunya fever. In Papua New Guinea (PNG) serological surveys and mosquito isolation experiments suggest that arboviruses are prevalent throughout the country.
