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.

Hasmiwati, Rusjdi SR, Nofita E. 2018. Detection of Ace-1 gene with insecticides resistance in Aedes aegypti populations from DHF-endemic areas in Padang, Indonesia. Biodiversitas 19: 31-36. Aedes aegypti is distributed widely in West Sumatra as a primary vector of Dengue hemorrhagic fever, especially in Padang City. Synthetic insecticide control is one currently used method to prevent mosquito-borne diseases. The extensive, long-term application of Temephos along with inappropriate dosages, have resulted in the development of resistance in Ae. aegypti populations. Mutation of the Ace-1 gene, encoding an acetyl cholinesterase, is one of the mechanisms that confer resistance to organophosphate (OP). The Temephos resistance status of Ae. aegypti in Padang city has not yet been studied. This study aimed to investigate the resistance status of Ae. aegypti and identify any possible mutation (s) of the Ace-1 gene in Padang city. Ae. aegypti samples were collected in five population in Padang city (Jati (JT), Gunung Pangilun (GP), Lubuk Minturun (LM), Korong Gadang (KG), and Bandar Buat (BB)). The larval susceptibility to Temephos was tested by larval bioassays with Temephos pestanal at 0.02 mg/L dosages. Larval susceptibility was determined by mortality percentage values. The relationship between Ace-1 genotypes and the resistant phenotype was analyzed by percentage of genotype frequency. Out of five populations, assessed by larval bioassays, JT and GP were resistant to Temephos; LM, KG, and BB were tolerant. A total of 50 individuals from larval bioassays were genotyped for Ace-1 gene. Our findings showed that Ace-1 was 495 bp in length. Mutation was not found in the G119S location but in the T506T location. Three alleles in T506T location were detected, including a wild type allele, TT (65.21%), and two mutant alleles, TA (26.08%), AA (8.69%). The use of Temephos showed that some Ae. aegypti populations were resistant, others were tolerant, but no population was vulnerable to Temephos. A novel mutation was detected as substitution in T506T location (ACT>ACA).

Abstract Dengue Hemorrhagic Fever (DHF) in Indonesia has spread in 34 provinces and 463 districts/cities. The Incidence Rate (IR) of DHF in East Sumba Regency in 2016 was 28.84 and 2017 increased to 55.28/100,000 population. The descriptive research was to describe the pattern of the spread of DHF cases and the habitat for the proliferation of DHF vectors and index pupae in the DHF endemic and non-endemic areas.The results showed that the Nearest Neighbor Ratio value in endemic areas was 0.292003 and in non-endemic areas was 0.718375. Moreover, the house pupae index was 53.3% and 41.0%, respectively The number of pupae/houses in endemic areas was 16.9 pupae/house, and in non-endemic areas was 11.9 pupae per house. The average pupae in each container in endemic areas were 3.6 pupae/container and sporadic areas were 2.2 pupae/container. The pupae/person value in endemic areas was 3.5 pupae/person and non-endemic areas was 2.2 pupae/person. The study concluded that there was a spatial relationship between DHF cases and DHF vector habitat with cluster distribution patterns. The number of pupae per house and pupae per person is still above the threshold value for DHF transmission in both endemic and non endemic areas.

The pathogenicity of the shrew-borne Imjin virus (MJNV) is unknown. The objective of our study was to find serological evidence of MJNV infection in humans. Partial MJNV nucleocapsid protein (NP) was cloned and expressed as an antigen for double-antigen sandwich ELISA, IgM capture ELISA, and dot blot to detect MJNV specific antibodies in hemorrhagic fever with renal syndrome (HFRS) patients’ and healthy persons’ sera from endemic areas in China. The purified recombinant NP reacted with neither the 90 healthy individuals’ sera from non-endemic areas of MJNV nor the 100 antisera to HFRS-causing virus, indicating that the MJNV NP had no cross-reaction with normal human sera and HFRS-causing viral antibodies. As determined by screening ELISA and dot blot analysis, IgG antibodies against MJNV NP were detected in sera from two of 385 healthy individuals from MJNV-endemic areas, suggesting infection with MJNV or MJNV-like thottimvirus. Based on the suggestive evidence, healthcare workers should be alert to febrile diseases occurring among individuals with exposure to shrew-infested habitats.

Severe fever with thrombocytopenia syndrome (SFTS), a newly emerging tick-borne viral disease, has been detected in Asia since 2009, and person-to-person transmission is possible. SFTS is characterized by atypical signs, including mild to severe febrile illness similar to that associated with hemorrhagic fever, with 16.2 to 30% mortality. We found that the titers of neutralizing antibodies, play an important role in protective immunity, to SFTS virus (SFTSV) in survivors and healthy residents who lived in endemic areas and who were positive for SFTSV IgG, were higher than those in non-survivor patients. Moreover, the titers were maintained in surviving patients and healthy residents but not in non-surviving patients in South Korea.

Knowledge Attitude And Practice

Dengue hemorrhagic fever (DHF) is an infectious disease caused by dengue virus, which is one of the serious public health problems in Indonesia, particularly Pekanbaru City, Riau Province, Indonesia. One of the DHF endemic locations in Pekanbaru City is Payung Sekaki Health Centre, where 52 DHF cases and no deaths were reported in 2018. The number of DHF cases has increased to 53 and caused 1 death in January-August 2019 period (CFR = 1.89%). Karya Wanita Rumbai Health Centre is one of the DHF non-endemic areas in Pekanbaru City, where only 10 DHF cases and no deaths were reported in January-August 2019 period. The purpose of this study was to compare the knowledge, attitude, and practice of DHF prevention between mothers in endemic and non-endemic areas of Pekanbaru City, Riau Province, Indonesia. The design of this study was observational, with a cross-sectional approach. The sampling technique used in this study was accidental sampling, which included 100 respondents from each region. The data source of this study consisted of primary and secondary data. Data analysis was performed using bivariate analysis with Mann Whitney statistical test because the data were not normally distributed. The results of the study showed that there were no differences in knowledge (p-value = 0.912) and attitude (p-value = 0.065) of DHF prevention between mothers living in the endemic and non-endemic areas of Pekanbaru City, Riau Province, Indonesia. However, there were differences in practice of DHF prevention between mothers (p-value = 0.002) living in the endemic and non-endemic areas of Pekanbaru City, Riau Province, Indonesia. The conclusion of this study is that there is no difference in knowledge and attitude of DHF prevention between mothers living in the endemic and non-endemic areas, but there are differences in DHF prevention practice between mothers living in the endemic and non-endemic areas of Pekanbaru City, Riau Province, Indonesia.

The Relationship

Background: Community vulnerability is influenced by the low participation of the community in Pemberantasan Sarang Nyamuk (PSN). PSN is an activity done by society independently in their respective environment to eliminate mosquito-breeding places by 3 M (Menguras, Menutup, Mengubur). We aimed to prove the relationship between knowledge and practice of the community in PSN with the incidence of Dengue Hemorrhagic Fever (DHF), beside to describe the map of vulnerability of the community in endemic areas of DHF. Methods: This study used case control design. The population of this research is the community in the area of Puskesmas Kembaran 1 and 2. The samples were taken from Bojongsari villageas, Banyumas districtis, Indonesia one of the endemic areas of DHF from Jan 2014- Dec 2015. The number of samples was 62 respondents. Results: The community in endemic areas of knowledge about dengue was mostly good (55%) but in practice PSN was mostly less (56%). There was no correlation of knowledge with the incidence of DHF (P=0.444) and there was an association of DHF occurrence with PSN practice (P=0.010) and the vulnerability map showing many negative DHF residents living close to dengue cases. Conclusion: Community vulnerability in DHF endemic areas is dominated by densely populated settlements, Slum environmental conditions, and PSN practices are lacking. Mobilization of all components of the communityis required to participate in prevention of DHF.
