Dengue Fever Gravidtrap Index Update The monthly gravidtrap index for aedes albopictus mosquitoes in august 2024 dropped further to 2.5 per cent from 4.5 per cent in july and was at the lowest level 1, indicating that the distribution of aedes albopictus mosquitoes in the areas surveyed was not extensive. in august, all the 64 survey areas were recorded with a gravidtrap index. Eggs can withstand drought very well. breed in small containers such as cans, discarded tyres, tree holes, rock pools and bamboo ends holding small amount of water. adults rest in shrubby area. adult has a white stripe on the dorsal surface of thorax and bands on legs. although exophilic, adults may also enter into houses.
Dengue Fever Gravidtrap Index Update Information of major port areas. the port monthly gravidtrap index and the port monthly density index for aedes albopictus for august 2024 are 1.6% and 1.1 respectively. port gravidtrap indices and port density indices for aedes albopictus in 2024 are provided below: port areas (map) port area. jan. Dengue fever is a notifiable disease in malaysia, and all suspected confirmed dengue fever cases have to be notified. confirmed dengue is defined as a case compatible with clinical description of dengue and laboratory confirmed with any of the following: detection of dengue ns1, dengue igm igg seroconversion in paired sera, detection of dengue. Dengue is the most common mosquito borne disease worldwide. this disease is caused by four distinct but closely related dengue viruses (dengue 1, 2, 3, and 4). dengue viruses are spread by the bites of infected aedes species mosquitoes. in the united states, public health authorities in puerto rico declared an outbreak in march 2024. Cdchan 00511. summary. the centers for disease control and prevention (cdc) is issuing this health alert network (han) health advisory to notify healthcare providers, public health authorities and the public of an increased risk of dengue virus (denv) infections in the united states in 2024. global incidence of dengue in 2024 has been the.

The average gravitrap index (gi) and fan trap index (fi) values were 0.68 and 3.39 respectively at peak catch times from june to august 2019, with consistently higher fi values calculated in all areas studied. we compared trap indices to reported cases of dengue fever and correlated them with weekly fluctuations in temperature and rainfall. This study introduces a new entomological index, gravitrap aegypti index (gai), which estimates the adult female aedes aegypti population in the community and presents its association with dengue cases. gravitraps were deployed across 34 treatment sites in singapore from september 2013 to september 2016.
