Dengue Vector Control

The control of dengue relies on the elimination of vector breeding sites. This study identified the container categories most productive for A. aegypti within the framework of the São Paulo dengue vector control program (DVCP) in São Sebastião, a large city located on the state’s coast where dengue cases have occurred since 2001. Containers were inspected monthly for the occurrence of mosquito immature stages during two consecutive vector-breeding seasons in 2002–2004. Containers were classified by their material, use, and fixed or removable status. Pupal productivity differed significantly among container types, items made of metal and plastic, and boats being those with the highest relative contribution. Significant correlations between traditional indices of A. aegypti abundance (Container Index, House Index, and Breteau Index) and pupal productivity/demographic indices (Pupae/Container, Pupae/House, Pupae/ha, and Pupae/Person) ranged 0.56–0.65; correlations were not statistically significant for any combination involving the Pupae/Container index. The assessment of pupal productivity indices could be incorporated into the DVCP without any additional operational onus, allowing vector control managers to determine appropriate control actions targeting the most productive containers and sites. Further studies are needed to assess whether pupal productivity indices may be used as epidemiological indicators of risk of dengue transmission.

Dengue fever and dengue haemorrhagic fever still becomes public health problems in South Sumatera Province with all of its regencies/cities have infested with Aedes aegypti. This research aimed to determine Aedes entomological indices and its breeding habitats. The research located at 11 regencies/cities, where in every regencies/cities determined two clusters (village) based on incidence rate in the last three years. Survey of preadult mosquito was carried out inside and outside areas of 1181 houses using single larva method with modification. The survey found that the dengue vector indices for house index, breteau index, and container index were at range 22,6% - 60,6%, 26,4 – 154,1 and 8,0% - 36,2%  respectively. The most dominant water holding containers found infested with pre-adults mosquito were cement tanks (33,4%), followed by buckets (18,2%) and drums (14,7%). Inside houses, larva or pupae found dominants in cement tanks (44,3%), buckets (19,5%) and drums (13,9%), while outside of the house were used containers (20,7%), followed by drums (16,7%), buckets (15,0%) and used tires (11,9%). Statistical analysis by chi-square test showed a significant relationship between infested of Aedes pre-adults with characteristic of  containers (colours, volume, location found and containers). Larval survey by visiting houses should carry out routinely and integrated into dengue vector control program.

Dengue Vector Control

Over a past decade, an administrative decentralization model, adopted for local administration development in Thailand, is replacing the prior centralized (top-down) command system. The change offers challenges to local governmental agencies and other public health agencies at all the ministerial, regional, and provincial levels. A public health regulatory and legislative framework for dengue vector control by local governmental agencies is a national topic of interest because dengue control program has been integrated into healthcare services at the provincial level and also has been given priority in health plans of local governmental agencies. The enabling environments of local administrations are unique, so this critical review focuses on the authority of local governmental agencies responsible for disease prevention and control and on the functioning of local legislation with respect to dengue vector control and practices.
