Dengue is one of the infectious diseases which is endemic in the tropical and sub-tropical country. The disease found in IndonesiaÂ Surabaya, 1968. The symptoms of Dengue virus infections are two kinds, first DF (Dengue Fever), second DHF (Dengue HemorrhagicÂ Fever). This infectious disease transmitted by Aedes aegypti mosquito. Mosquitoes breed in clean water areas. More than 100,000 casesÂ of DF/DHF ccurred in Indonesia every year. The purpose of this study were to provide information and the spread of dengue virusÂ types in Surabaya from January 2013 to September 2013. The nalysis technique used to determine the type of dengue virus nfectionwas used PCR (Polymerase Chain Reaction). The results obtained 69% DENV-1, 27% DENV-2 isolates, 4% isolates DENV-3, andÂ 0% DENV-4 isolates.

Introduction: Aedes aegypti is the main dengue vector in Indonesia. One of the dengue controls is through insecticides use. The plant-based insecticide is one alternative that can be used to minimize the impact of chemical insecticides. Ocimum basilicum is one of the plants that have the potency to be used as insecticides. The aims of this study were to analyze the insecticide activity of Ocimum basilicum essential oil against Aedes aegypti as well as its Lethal Concentration (LC50 and LC90) and Knockdown Time ( KT50 and KT90).Methods: Treatment groups were given Ocimum basilicum essential oil of 100 ppm, 50 ppm, and 25 ppm. The tests were performed four times with 10 mosquitoes per test.Results: The mortality rate of the mosquito on the extract with a concentration of 100 ppm was 100%, 50 ppm was 10% and 25 ppm was 0% and the value of LC50 = 62.9 ppm and LC90 = 78.7 ppm. KT50 of this study was 19.4 minutes and KT90 was 8.07 minutes.Conclusion: Ocimum basilicum essential oil has a mosquitocidal effect on Aedes aegypti. Further studies to investigate the substances of Ocimum basilicum against Aedes aegypti are needed.

This research was aimed to describe the density pattern and the fluctuation of Aedes aegypti larval based on the season in dengue haemorrhagic fever (DHF) endemic area in Surabaya city. The population of the research was the house of people together with its breeding sites either inside and outside the house. The 55 houses were randomly chosen in 11 RWs in Nginden Subdistrict. The sample of this research was Aedes aegypti larva obtained from its breeding sites. The sample sizes were all of the larval in the containers existed in the chosen houses. The samples of the larval were taken and carried for identification and documentation of the species. This research was applied in the same houses in January, March, and May 2008 in rainy season. The results indicated that the highest larval index occurred in January with House Index (HI) 76.8%, Container Index (CI) 40.5%, and Breteau Index (BI) 137.5%. There was a decrease in March with HI 63.3%, CI 31.3%, and BI 92.7%. It continued to decrease in May with HI 42.6%, CI 21.1%, and BI 57.4%. All of those larval indices in the three observed months showed a high percentage of larval which was much higher than the safe limit or the critical threshold (5%) as defined by WHO. It implied that people in Nginden Subdistrict were threaten by the infection of DHF. The three indices achieved the peak in January, which was also the peak of the rainy season. It gradually decreased in March and May as the rainy season decreased its intensity of rain. Larval Density Index (LDI) also showed a high value. There were 173 larval/house in January, 187 larval/house in March, and 84.8 larval/house in May. The containers or breeding sites of Aedes were mostly found in January then their existences gradually decreased in March and May. Traditional bath tub was the most productive container inside the house, while drum and bucket were the most productive containers outside the house. Other containers which contributed abundance of larval were refrigerator, flower pot, well, and PDAM meter box.

Dengue virus (DENV) is a significant pathogen emerging worldwide as a cause of infectious disease. Antidengue treatments are urgently required to control the emergence of dengue. DENV is a mosquito-borne disease responsible for acute systemic diseases and serious health conditions. DENVs were distributed in the tropical and sub-tropical areas and transmitted to humans by Aedes agypty and Aedes albopictus. Dengue vaccine or antiviral has not yet been clinically approved for humans, even though there have been great efforts toward this end. Antiviral activity against DENV is an important alternative for the characterization and development of drugs. Metal–organic compounds were reported to exhibit fungicidal, bactericidal, and antiviral activities its inhibitory activity was not significant, at high concentration it was more toxic to replicating cells than to stationary cell monolayers of Vero cells. The aim of this study is to investigate the antiviral effects of Cobalt(II)–Morin complex. This compound was further investigated for its inhibitory effect on the replication of DENV-2 in Vero cells. The replication of DENV was measured by enzyme-linked immunosorbent assay and the value of selectivity index (SI). SI was determined as the ratio of the 50% cytotoxic concentration (CC50) to the 50% inhibitory concentration (IC50). The IC50 value of the Cobalt(II)–Morin complex for DENV-2 was 3.08 µg/ml, and the CC50 value of the complex for Vero cells was 3.36 µg/ml; thus, the SI value was 1.09. The results of this study demonstrate the antidengue serotype 2 inhibitory activity of Cobalt(II)–Morin complex and its high toxicity in Vero cells. Further studies are not required before Co(II)–Morin can be applied in the treatment of DENV-2 infections.

Dengue virus (DENV) is mosquito-borne viral diseases, transmitted by the vector mosquitoes such as Aedes sp. Infection with four serotypes of DENV-1 to 4. Indonesia, dengue haemorrhagic fever (DHF) was first recognized in 1968 in the cities of Jakarta and Surabaya. In 2007, we started DENV surveillance in Surabaya supported by the joined program of the Japan Initiative for Global Research Network on Infectious Disease (J-GRID) established the Indonesia-Kobe University Collaborative Research Center for Emerging and Reemerging Infectious Diseases (CRC-ERID). The results of serotype and genotype, in Surabaya and Bangkalan are similar with previous result in Indonesia, but especially in Bogor similar with Japan 2014. This study showed the importance of continuous virus surveillance in dengue endemic areas, in order to understand the dynamic of dengue infection disease in Indonesia.
