“…And it is ready to transmit the Dengue virus to humans. Transovarial transmission of Dengue virus plays a role in the sustainability of the transmission of Dengue both at the time of epidemic as well as between epidemic because the mosquitoes that have been infected with Dengue virus can transmit the virus throughout their life, although they never suck infected human blood (Ditjen PP & PL, 2013;Espinosa, 2014) ,…”

Dengue is an endemic disease in almost all provinces in Indonesia, including NTT pro-vince and Kupang City. DHF prevention and control efforts need to be accompanied by understanding of the epidemiological and entomological aspects. This study proves the presence of transovarial transmission and serotypes of Dengue virus in Ae. aegypti in areas with different endemics in Kupang City. The study was conducted in endemic, sporadic and Dengue-free villages. Samples from each location were 30 head squash Ae. aegypti females for examination of Dengue virus by IHC methods and 10 Ae. aegypti females for serotypes check of Dengue virus with RTPCR. Data presented in tables and images then analyzed descriptively. This study finds that transovarial infection rates 9.2% with serotype Dengue virus-1. As many 97.5% of respondents have heard about Dengue by most cadres resources (24.5%) and health workers (24%). Transovarial infection is found in endemic, sporadic and free areas so that the Dengue vector control needs to be done in the three regions with different endemicity.

“…The infected mosquito will contain virus for its whole life and it can transmit virus through ovarium (Lee and Rohani, 2005;Espinosa et al, 2014). This transovarian transmission will make the pre-adult stadium contain virus as well, so that it can increase the number of mosquitos that contain virus in mosquito population which eventually will preserve even trigger the epidemy (Hartanti et al, 2010).…”

Background: Dengue is a disease related to the environment that spreads rapidly. Prevention movement is considered ineffective; therefore, a more efficient early warning system is required. It is required strongly correlated variables to as predictor in early warning system. This study aims to identify the environmental conditions associated with dengue. Materials and methods: This ecological study was conducted on five sub-districts selected based on the trend of the incidence. Data land cover and elevation obtained using GIS. Climate data were obtained from Meteorology and Climatology and Geophysics Agency of Yogyakarta. Results: There were 1.150 dengue cases from 2008-2013 obtained from District Health Office. The spatial pattern is clustered in all sub-districts (Z-score < -2.58). There is a positive correlation between land cover and dengue (p 0.000; r 0.284) and a negative correlation between elevation areas and dengue (p 0.000; r -0.127). Multiple Regression Test shows the effect of humidity (p 0.000) and rainfall (p 0.002) with a contribution of 13.5% -27.4% (r 2 0.135 -0.274), while temperature has no effect in all sub-districts (p > 0.05). There is no effect of climate parameters in sporadic dengue areas (p > 0.05). Conclusion: It is concluded that dengue in Sleman is clustered and associated with the environment parameter, even though it does not have close correlation. High elevated and small building area is consistent with the lower dengue cases. Humidity and rainfall affect dengue, but temperature does not affect dengue.

27 Background 28 Three arthorpod-borne viruses (arboviruses) causing human disease have been the focus 29 of a large number of studies in the Americas since 2013 due to their global spread and 30 epidemiological impacts: Zika, dengue, and chikungunya viruses. A large proportion of 31 infections by these viruses are asymptomatic. However, all three viruses are associated with 32 moderate to severe health consequences in a small proportion of cases. Two mosquito species, 33 Aedes aegypti and Aedes albopictus, are among the world's most prominent arboviral vectors, 34 and are known primary vectors for all three viruses in the Americas. 35 Objectives 2 36 This review summarizes the state of the entomological literature surrounding the biology 37 and ecology of vectors of Zika, dengue and chikungunya viruses and factors affecting virus 38 transmission. The rationale of the review was to elucidate consensus and discord between 39 studies, and guide future research based on identified knowledge gaps. 40 Results 41 A total of 196 studies were included in the scoping review after initial screening and 42 subsequent exclusion of out-of-scope studies, secondary data publications, duplicate records, and 43 studies unavailable in English language. 44 Key findings 45 Temperature and humidity have the strongest impact on mosquito distribution and 46 dynamics, development of immatures and arborviral infection rates. Low socioeconomic status 47 and related factors, including poor infrastructure, inconsistent access to water, and high 48 household resident density, have been consistently associated with arbovirus vector occurrence. 49 Effects of interspecific competition on arboviral vector species is currently poorly understood. 50 Vector competence for Zika virus is well established for Ae. aegypti and Ae. albopictus. 51 Information on Zika virus vector transmission dynamics is sparse in contrast to the wealth of 52 research available for dengue and chikungunya viruses. 53 Conclusions 54Based on the internationally recognized urgency of Zika virus infection as a public health 55 concern, further research on arbovirus vectors and transmission dynamics is of pressing need. 56 57
