Abstract

Background: Dengue and chikungunya are mosquito-borne viral diseases that are of public health importance throughout the tropical and subtropical regions of the world. Seasonal variations in transmission of these viruses have been suggested owing to the ecology of their mosquito vectors. However, little is known about the epidemiology of the diseases Tanzania. To address this gap, seasonal community-based cross-sectional surveys were undertaken to identify potential clusters of transmission in Hai district in northern Tanzania. Methods: Epidemiological and entomological data from two cross-sectional surveys were used to examine the spatial pattern of dengue and chikungunya transmission. Six villages namely, Boma Ng’ombe, Magadini, Rundugai, Nshara and Kware were involved in the study. Serological measures of dengue and chikungunya virus infections were derived using enzyme-linked immunosorbent assays, and all participants were geo-referenced to the household level using a global positioning system. Potential clusters of individual exposed to dengue and chikungunya virus, as well as clusters of Aedes mosquitoes in the wet and dry seasons were detected using SaTScan. All significant clusters (with p≤0.05) were mapped using ArcGIS. Results: A large, widely dispersed cluster of chikungunya exposed individuals was detected spanning Rundugai and parts of Magadini villages (RR = 2.58, p= 0.01), while no significant clustering was observed in the dry season. Spatial clusters of Aedes aegypti were detected in Rundugai in both the wet and dry seasons (RR = 2.56, p< 0.001 and RR = 2.24, p=0.05, respectively). In the dry season a small cluster was also detected in Kware (RR = 2.25, p=0.05). No significant clusters of dengue were detected in both seasons. Conclusion: Clusters of chikungunya-exposed individuals and Aedes mosquitoes indicate on-going transmission of chikungunya virus in Hai district of northern Tanzania.

18. Updated Bionomics of Toxorhynchites aurifluus and Toxorhynchites manicatus in Taiwan.

Abstract

The larvae of the genus Toxorhynchites are typically found in sylvatic habitat environments. They have been proposed as potential biocontrol agents against disease vectors such as Aedes, specifically the larvae of Ae. aegypti and Ae. albopictus. The only 2 species of Toxorhynchites identified in Taiwan are Tx. aurifluus and Tx. manicatus, but there have been no published records of either species since 1984. In January 2014, we identified 2 4th-stage Tx. aurifluus larvae and 2 4th-stage Tx. manicatus larvae in artificial habitats close to dwellings in Guichong village, Pingtung County, Taiwan. Here we update the bionomics of the larvae of both species, including coexisting aquatic fauna, the physicochemical parameters of the larval habitats, and developmental time. We further compare the findings with past records. [ABSTRACT FROM AUTHOR]
