Abstract: Dengue Hemorrhagic Fever (DHF) is one of the most serious health problems in Indonesia which often causes outbreaks with numerous deaths. The disease is transmitted byAedes sp.females. Generally, dengue virus transmission occurs horizontally from human carriers, and the dengue viruses are passed on bytheir vectors through blood sucking activity. After propagation in the mosquito, the viruses are transmitted to human recipients. In addition, there is a vertical transmission (transovarial) of dengue virusesin the ova of Aedes sp.females. The viruses propagate in the ova that undergo  metamorphosis to become larvae, pupae, and imagoes. The transovarial transmission of dengue virusesin its vectors in endemic areas could be a causative key which is responsible for the phenomenon of increasing cases of DHF. Any effort to prevent and control DHF requires a thorough understanding about virDen transmission, including this transovarial transmission in Aedes spfemales. Keywords: DHF, transovarial transmission, Aedes sp.     Abstrak: Penyakit Demam Berdarah Dengue (DBD) merupakan salah satu masalah kesehatan yang semakin serius di Indonesia dan sering menimbulkan suatu Kejadian Luar Biasa (KLB) dengan jumlah kematian tinggi. Penyakit ditularkan melalui Aedes sp.betina. Transmisi virus dengue umumnya terjadi secara horizontal, yaitu dari manusia pembawa virus dengue ke nyamuk vektor Aedes sp. melalui aktivitasnya mengisap darahSetelah mengalami propagasi  dalam  tubuh nyamuk, virus dengue ditularkan ke  manusia penerima. Selain itu, transmisi virus dapat terjadi secara vertikal (transovarial) yaitu virus dengue dalam tubuh nyamuk vektorAedes sp. betinake ovum, kemudian berpropagasi dalam ovum, larva, pupa, dan imago. Transmisi transovarial virus dengueke vektornya di daerah endemik bisa menjadi kunci penyebab yang bertanggung jawab terhadap fenomena peningkatan kasus deman berdarah dengue. Upaya pencegahan dan penanggulangan DBD memerlukan pengetahuan yang matang tentang adanya infeksi transovarial virDen pada nyamuk Aedes sp. Kata kunci : DBD, transmisi transovarial,  Aedes sp.

Background: The higher incidence of dengue fever in Pakistan demands additional efforts in order to limit the disease. Despite active public health campaigns, low public awareness is one of the factors facilitating dengue virus transmission. For effective preventive measures, the assessment of the knowledge gap and then taking appropriate steps to fill the gap is required.The objective of this study is to assess knowledge about dengue fever prevention among people visiting Benazir Bhutto Hospital, Rawalpindi.Methods: The descriptive cross-sectional study of 6 months duration was conducted with 280 participants selected via nonprobability convenience sampling. After informed consent, an interview was conducted based on a questionnaire that assessed socio-demographic parameters and knowledge about dengue virus transmission and prevention. Data were analyzed through SPSS v. 22. The study was approved by the Ethical Review Board (ERB) of Rawalpindi Medical University and Allied hospitals.Results: Out of 280 respondents, 54.6% were males and 45.4% females and the mean age was 35.0 ± 13.1 years. The respondents having high knowledge scores were 66(23.6%) while those having moderate and low scores were 159 (56.8%) and 55 (19.6%) respectively. Educated respondents (p=0.03) and urban residents (p=0.05) had higher knowledge scores.Conclusion: The majority of the participants know about dengue fever. However, only one out of every four respondents has good knowledge scores for dengue fever prevention.

The wMel strain of Wolbachia can reduce the permissiveness of Aedes aegypti mosquitoes to disseminated arboviral infections. Here, we report that wMel-infected Ae. aegypti (Ho Chi Minh City background), when directly blood-fed on 141 viremic dengue patients, have lower dengue virus (DENV) transmission potential and have a longer extrinsic incubation period than their wild-type counterparts. The wMel-infected mosquitoes that are field-reared have even greater relative resistance to DENV infection when fed on patient-derived viremic blood meals. This is explained by an increased susceptibility of field-reared wild-type mosquitoes to infection than laboratory-reared counterparts. Collectively, these field- and clinically relevant findings support the continued careful field-testing of wMel introgression for the biocontrol of Ae. aegypti-born arboviruses.
