Dengue hemorrhagic fever is a severe and fatal infection that occurs in tropical regions such as Indonesia. In 2014, recorded that dengue morbidity rate was 5.17 per 100,000 inhabitants (approximately 13031 cases) with mortality rate of 0.84% (110 deaths). Demographic and societal changes such as population growth, urbanization, and modern transportation appear to play an important role in the increased incidence and geographical spread of dengue virus. Aedes aegypti, the urban yellow fever mosquito, is also the principal dengue-carrying vector. The Aedes aegypti mosquitoes as a vector of dengue virus normally live and breed in clean water reservoirs that are not directly related to the land such as: bath, bird drinks, water pot, water jars / barrel, cans, old tires, etc. In Indonesia, dengue outbreaks often occur when the seasons change from dry to rain hor vice versa. This study aimed to figure out the influence of natural environment and the existence of the vector’s larva. A logistic regression was performed to ascertain the effects of temperature, humidity, water replacement and the existence of water reservoir on the likelihood of the existence of the vector’s larva . The logistic regression model was statistically significant, p < .005 and the model explained 69% (Nagelkerke R2). This finding shows that the existence of the mosquito’s larva, influenced by temperature, water replacement activity and the existence of water reservoir. Health education about vector control and environmental engineering are necessary to break the chain of mosquito breeding.

Background: The incidence rate (IR) of Dengue Hemorrhagic Fever per 100,000 population in Central Java has increased dramatically in five years. Banyumas Regency is an endemic area of ​​dengue hemorrhagic fever in Central Java Province. The cause of dengue hemorrhagic fever is four dengue viruses known as DEN-1, DEN-2, DEN-3, and DEN-4. The purpose of this research is to detect transovarial dengue virus in Aedes aegypti mosquito in Banyumas Regency. Methods: The study was conducted by installing ovitrap in Mersi Village, East Purwokerto District, and in Pliken Village, Kembaran District, Banyumas Regency. The study was conducted by installing ovitrap in Mersi Village (9 samples) and Pliken Village (3 samples). The eggs obtained are hatched into larvae in the laboratory. The 3rd and 4th instar larvae were examined for the presence of dengue virus using the Elisa method. Result: The results showed that in Mersi Village, there were two positive samples, and in Pliken Village, there was one positive sample containing dengue virus. The presence of the dengue virus found in the hatched Aedes aegypti larvae (F1) indicates that there has been a transovarial dengue virus from the parent mosquito in its offspring. Conclusion: The study concluded that in Banyumas District, a dengue virus transovarial had occurred in Aedes aegypti mosquitoes. The government and the community should increase efforts to eradicate mosquito nests (dengue hemorrhagic fever) to reduce the vector population of dengue hemorrhagic fever so that cases of dengue hemorrhagic fever can be eliminated.    Keyword: Transovarial dengue virus, Aedes aegypti, Dengue Hemorrhagic Fever

TRANSOVARIAL TRANSMISSION OF DENV IN AEDES AEGYPTI Background: Transovarial transmission of dengue virus in Aedes aegypti mosquitoes is a vertical transmission of dengue virus infection in female Ae. aegypti mosquitoes to the offspring. The phenomenon of transovarial dengue virus transmission in Dengue Hemorrhagic Fever (DHF) vectors has been proven by laboratory and nature, which indicates the transovarial transmission of dengue virus has an important role in maintaining the dengue epidemic. DHF vector control especially Ae. aegypti mosquitoes is an effective method of stopping transmission and expansion of dengue cases.Purpose: This scientific article aims to understand the spread of dengue virus transovarially in dengue mosquito vectors, and its relation to the prediction of outbreak dengue cases as information on DHF vector surveillance so that it can make the appropriate control program.Methods: Collecting several scientific articles to obtain information on the studies that have been done and summarizing the results of the study.Results: Several result of study are proving that transovarial transmission of dengue virus in Aedes spp. mosquitoes  can predict dengue outbreaks case by monitoring the stadium immature Aedes sp., but it need further comprehension statistically about occurrence of dengue outbreaks and the increasing of dengue virus infections in immature stadium of mosquitoes.Discussion: Transovarial transmission rates from Ae. aegypti mosquito sample obtained from nature may be lower than in the laboratory, because laboratory condition can be controlled in accordande with the development of viruses in mosquito bodies. The dengue virus is proven to be able to spread between stages from eggs, larvae, pupae to imago and Ae. aegypti mosquitoes can act as reservoirs for  dengue virus until the 7th progeni.Conclusion: Dispersion dengue virus through transovarial in Ae. aegypti mosquito playing important role in viruses maintained in nature during absence of viremic vertebrata host or when the climate condition are not favorable for that viruses. Continuous monitoring of Ae. aegypti mosquitoes population vector related the early detection of virus circulation may contribute to the prediction models for dengue outbreaks, so that DHF control can be more effective.Pendahuluan: Penularan virus dengue secara transovarial pada nyamuk Aedes aegypti adalah transmisi secara vertikal dari nyamuk Ae. aegypti betina yang infektif virus dengue kepada keturunannya. Fenomena penularan transovarial virus dengue pada vektor Demam Berdarah Dengue (DBD) telah banyak dibuktikan skala laboratorium dan secara natural di alam, yang mengindikasikan penularan transovarial virus dengue memiliki peranan penting dalam mempertahankan epidemik DBD. Pengendalian vektor DBD khususnya nyamuk Ae. aegypti merupakan salah satu metode efektif dalam menghentikan penularan dan perluasan kasus DBD.Tujuan: Studi ini untuk memahami penyebaran virus dengue secara transovarial  pada vektor nyamuk DBD, serta kaitannya  terhadap prediksi kasus luar biasa (KLB) DBD sebagai informasi surveilans vektor DBD sehingga dapat membuat program pengendalian yang tepat.Metode: Dengan mengumpulkan beberapa artikel ilmiah untuk mendapatkan informasi studi yang telah dilakukan sebelumnya dan membuat ringkasan dari hasil studi tersebut.Hasil: Beberapa studi membuktikan penelitian transovarial virus dengue pada nyamuk Aedes spp. dapat memprediksi kasus KLB DBD dengan cara memonitoring stadium immature Aedes sp., namun perlu dilakukan studi statistik lebih lanjut untuk membuktikan hubungan terjadinya KLB DBD dan meningkatnya infeksi virus dengue pada stadium immature nyamuk.Pembahasan: Angka infeksi penularan transovarial virus dengue dari sampel nyamuk Ae. aegypti yang didapatkan langsung dari alam lebih rendah dari skala laboratorium, dikarenakan kondisi laboratorium dapat dikendalikan sesuai dengan perkembangan virus ditubuh nyamuk. Virus dengue terbukti dapat menyebar antar stadium dari telur, larva, pupa, sampai imago dan nyamuk Ae. aegypti dapat menjadi reservoir virus dengue sampai progeni ke 7.Kesimpulan: Penyebaran virus dengue secara transovarial pada nyamuk Ae. aegypti berperan penting dalam mempertahankan keberadaan virus di alam khususnya dimana tidak ada hospes vertebrata yang viremik atau ketika  keadaan (kondisi iklim) yang tidak menguntungkan virus tersebut di alam. Pemantauan berkelanjutan pada vektor demam berdarah nyamuk Ae. aegypti terkait deteksi dini sirkulasi virus dengue dapat berkontribusi pada pengembangan model prediksi KLB DBD, sehingga pengendalian DBD dapat lebih efektif.

Dengue hemorrhagic fever (DHF) is an infectious disease caused by dengue virus with the widest spread in the Asian region. In Indonesia, every year is always an outbreak in some provinces, the largest occurred in 1998 and 2004 with the number of patient mortality by 79 480 people with 800 people. To know the risk factor for dengue transmission in Cirebon District that had a high DHF cases, had been conducted the research with calculating the number and density of humans at the houses and also survey of density of Aedes aegypti pre-adult and adult stages.The research was resulting that the house index (HI) of Ae. aegypti is 58%, while homes found Ae. aegypti adults is 46%, 6 of which house is the house that is not found larvae / pupae of mosquitoes. The laboratory tests found that the frequency of biting Ae. aegypti mosquitoes average 4.5 times per day, at least 2 times and no more than 7 times per day. Number of people bitten by adult mosquitoes average of 3.1 people per day, is at least 2 people and maximum 5 people per day. Based on the statistically test, it is known that there is significant correlation between the number of inhabitants of the house and the presence of mosquito larvae / pupa of Ae. aegypti mosquito with biting frequency, whereas the most dominant variable was the presence of larvae / pupae of mosquitoes. Furthermore, it is advisable to do the cleaning intensification of Aedes breeding places inand outside the home including those hidden. It is also necessary to place residential settings so that the number of occupants per house so less.
