ABSTRACT : The House index and Container Index in the buffer area of ​​the working area of ​​Balikpapan Sepinggan Airport is still above 1%, so the potential for the spread of dengue disease. Mobilization of people, goods and transportation equipment will increasingly affect the transmission of disease in ports and airports, especially for vector-borne diseases. This study aims to analyze the risk factors associated with larvae density of Aedes aegypti and describe the larvae index in the buffer zone of the Sepinggan Balikpapan Airport This study was a descriptive study with a cross sectional design. The sample in this study was 121 houses with a proportionate stratified random sampling, the research location was in the buffer zone of Sepinggan Balikpapan Airport in November 2018. The variables studied were houses with positive larvae containers, breeding sites and PSN behavior and larvasidation. The data was analyzed using the chi square test. There was a relationship between houses with larvae positive Aedes aegypti, behavior of Mosquito Nest Eradication (PSN) and larvasidation with larvae density of Aedes aegypti but not for breeding sites (p = 0.00 and 95% CI = 0.64), and   (p = 0.00 and 95% CI = 0.34). The description of several Aedes aegypti larvae index, namely House Index (HI) = 57.02%, Container Index (CI) = 24.36%, Bruteau Index (BI) = 148.76, and Flick Free Numbers (ABJ) = 42.98 %. Houses with larvae of Aedes aegypti larvae and PSN and larvasidation behavior were associated with larvae density of Aedes aegypti. The index of HI, CI and BI larvae is of high value so there is a risk of DBD transmission

Minimum Infection Rate

Detection of viruses in human sera particularly in endemic areas is cumbersome and laborious. Therefore, an alternative approach, Immuno-fluorescence assay (IFA) was performed to determine dengue virus (DENV) positivity in mosquitoes. A total of 1055 adult Aedes aegypti female mosquitoes were tested for IFA test against DENV. Minimum infection rate (MIR) for DENV was found higher during August to November 2016 ranging from 10.75 to 20.83. The average yearly MIR was about 6.64. Higher MIR for Ae. aegypti was found in Sarfabad, Noida (12.71) and Khoda Colony, Ghaziabad (11.90). Minimum MIR (4.67) was observed in Sanjay colony (Faridabad). The main contribution of this study resides in the development of a more suitable monitoring system for early detection of viral circulation and to prioritize early intervention in the non-transmission season.

Mosquito index study of three ecologically different ecozones of the Thiruvananthapuram district, Kerala showed sharp difference on the proportionate distribution of Aedes aegypti and Aedes albopictus. Human dengue viremia (HDV) was very high in those ecozones where A.aegypti density was high and HDV was low where A.albopictus was high. In a coastal zone of Thiruvananthapuram city, A. aegypti was the most abundant vector and in a hilly, arid suburban zone, A.albopictus was the abundant vector. In the urban zone both species of mosquitoes showed equal distribution. Study on the circulating serotypes in the serum of HDV by Single step single tube Multiplex PCR showed all the four serotypes viz DENV1, DENV2, DENV3 and DENV4 in patients of Thiruvananthapuram city, which indicated the possibility of Dengue Shock Syndrome, unless there is efficient vector management. Among the four dengue serotypes, Type 1 was the most abundant virus. Abundance of microhabitats in Thiruvananthapuram city, which support A. aegypti may be the reason for high prevalence of dengue fever in the urban zone.

A dengue é um dos principais problemas de saúde pública no Brasil e no mundo, tendo como o vetor, o mosquito Aedes aegypti, cuja proliferação apresenta forte relação com fatores sociais. Sabendo – se que o município de Fernandópolis encontra-se entre os 25% dos municípios paulista com maiores números de casos de dengue e os fatores sociais são decisivos neste processo. O presente estudo tem como objetivo avaliar a influência de indicadores sociais nos casos positivos de dengue no município de Fernandópolis – SP. Trata-se de pesquisa exploratória, com dados secundários, por meio de modelos matemáticos, sendo analisada a densidade demográfica e renda bruta per capita, de 40 bairros no de 2011. Nestes bairros observou-se que tanto aqueles de alta, como naqueles de baixa densidade demográfica, houve aumento nos casos positivos de dengue. Também observou- se que os casos de dengue tenderam a reduzir com o aumento da renda bruta per capita.

Primary Vector

Aedes aegypti is the primary vector for the transmission of Dengue Fever (DF)/Dengue Haemorrhagic Fever (DHF). Entomological investigations on breeding habitats and larval prevalence of mosquitoes Aedes aegypti (L.) and Ae. albopictus (Skuse) were conducted from April to June 2009 in Kathmandu district, Nepal. Different water-filled containers were examined for the presence or absence of Aedes larvae. Larval survey techniques were used to obtain the House Index (HI), Container Index (CI) and Breteau Index (BI). The over all HI, CI and BI for Aedes aegypti were 6.25, 4.83, 9.37 and for Aedes albopictus were 6.25, 3.22 and 6.25 respectively. It was also observed that discarded tires lying outdoors were the preferred breeding habitats. No breeding was observed in other containers in April and May during this three months survey. Herewith, we report the first collection and identification of Aedes aegypti in Kathmandu during June, 2009. Indeed, this finding constitutes the first record from the capital of Nepal within the urban agglomeration of Basundhara and Gongabu-Balaju area.Therefore, DF/DHF transmission risk may occur locally if imported cases are introduced.  Key Words: Aedes aegypti; Ae. albopictus;  Kathmandu; First record; Dengue Fever.Journal of Natural History MuseumVol 24, 2009.Page:
