Transmission of Epidemic Dengue Hemorrhagic Fever in Easternmost Indonesia

Abstract

Abstract. In April 2001, a second suspected outbreak of dengue hemorrhagic fever in the easternmost region of Indonesia was investigated in Merauke, a town located in the southeastern corner of Papua, by the Indonesian Ministry of Health and the U.S. Naval Medical Research Unit No. 2. Principal case criteria of hemorrhagic disease provided for a study enrollment of 15 clinically acute and 37 convalescing subjects. Additionally, 32 comparable age/sex controls were selected from neighboring households. Laboratory diagnosis involved three testing methodologies: virus isolation by cell culture, a reverse transcriptase-polymerase chain reaction (RT-PCR) assay, and serologic assays. Antibody (IgM) to dengue virus was detected in 27% of the acute clinical cases, 30% of the convalescing cases, and only 3% of the matched controls. Dengue 3 was the only viral serotype detected from acute serum samples by the RT-PCR. The mean ± SD age of the acute and convalescing cases was 7.8 ± 5.4 years. Overall hospital records accounted for 172 suspected outbreak cases, all urban residents of Merauke with no recent travel history outside the area. The estimated outbreak-associated case fatality rate among all suspected dengue cases was 1.2%. A seven-year retrospective review of hospital records in Merauke showed negligible disease reporting involving hemorrhagic disease prior to the outbreak.

“…In our study the most common age group affected were above 30 years where as in earlier studies the age group varied from 0 to 30 years (Garg et al, 2011;Kavita, 2007;Sukri et al, 2003;Chakravarti and Kumaria, 2005). As majority of the individual affected in this study are from in patient and above the age of 30 years and majority of them being males in our study.…”

Seasonal factor is a supporting factor in the reproduction and the distribution of dengue vector and it is very potential to cause outbreak (Prasittisuk and Andjapraridze, 1996;Gubler, 1998, Sukri et al, 2003. In this study, an observation towards the fluctuation of Ae.…”
