Abstract

Zika virus can be transmitted through mosquitoes such as Aedes aegypti and Ae. albopictus. During the transition period of 2014–2015, an outbreak of dengue was reported in Jambi City, during which several sufferers were screened positive for Zika virus infection by the Eijkman Institute. It was interesting to note that all of those positive for Zika virus infection were indigenous residents and none of them had a history of international travel. This descriptive analytic study with a cross-sectional design study was conducted to present an overview of Aedes spp. Population using ovitrap and egg colonization methods and to detect the presence of Zika virus. Samples were analyzed using reverse transcription polymerase chain reaction for detection of Zika “like” virus and the mapping results were described. The Ovitrap Index was 44.74%, and examination of egg colonization collected from 40 neighborhoods revealed the presence of Zika “like” virus in samples obtained from the fourth neighborhood in Talang Bakung village. This result indicates the occurrence of natural vertical transmission of Zika “like” virus in A. aegypti mosquito in Jambi City, which potentially resulted in an outbreak.

Abstract

Elementary school is a place that can result in increase of dengue disease among children because of environmental factors, potential transmission, the absence of good environmental management system and some control efforts which are no longer effective. This study aimed to determine factors that potentially against transmission of dengue hemorrhagic fever in state elementary school, so the early warning system can be enforced. Type of study was analytic with cross-sectional design. The study was conducted in 91 state elementary schools in Yogyakarta City in 2014. Variables in the observation are virus serotype DEN, insecticide resistance, the density of vector and physical condition of schools. Data analysis used descriptive and correlation-regression (a = 5%). Results showed that there were eight schools with dengue virus serotype 2 and 3 mosquitoes declared to have mild and moderate resistance to organophosphate, the school environment was susceptible to transmission of dengue hemorrhagic fever based on the container index, house index, breteau index and ovitrap index, temperature and humidity inside and outside were potential to the high density of eggs, wire netting was not installed on ventilation and the very close distance between the buildings could lead to transmission.AbstrakSekolah dasar merupakan tempat yang dapat mengakibatkan peningkatan penyakit dengue pada anak karena faktor lingkungan, adanya potensi penularan, belum adanya system manajemen lingkungan yang baik dan beberapa upaya pengendalian yang tidak lagi efektif. Penelitian ini bertujuan untuk mengetahui faktor yang berpotensi terhadap penularan demam berdarah dengue bagi anak, sehingga sistem kewaspadaan dini dapat ditegakkan. Jenis penelitian ini adalah analitik dengan rancangan potong lintang. Penelitian dilaksanakan pada 91 sekolah dasar negeri di Kota Yogyakarta. Variabel yang diobservasi adalah serotype virus DEN, resistensi insektisida, kepadatan vektor,dan kondisi fisik sekolah. Analisis data menggunakan analisis deskriptif dan korelasi-regresi (a = 0.05). Hasil menunjukkan bahwa terdapat delapan sekolah dengan virus dengue serotip 2 and 3, terjadi resistensi insektisida organofosfat tingkat ringan dan sedang, lingkungan sekolah telah rentan terhadap penularan demam berdarah berdasarkan container index, house index, breteau index dan ovitrap index, suhu dan kelembaban di dalam dan luar ruangan berpotensi terhadap tingginya kepadatan telur, ventilasi tidak terpasang kawat kasa, dan jarak antara bangunan sangat dekat dapat menyebabkan penularan menjadi sangat cepat.

Abstract

Indonesia is a member of Southeast Asia Regional Office (SEARO) ranked the first in dengue hemorrhagic fever (DHF) problem based on incidence rate (IR) and case fatality rate (CFR). Several provinces in Indonesia experience an outbreak, one of which is the Mataram City in West Nusa Tenggara Province. Mataram City is an endemic area of DHF because the DHF cases are always found in three consecutive years with the number of cases that fluctuate and tend to increase. This study aimed to obtain factors that could be used to improve early warning systems in controlling DHF. This study used a case control design with a ratio of 1:1 to 180 house holds. The results showed that home environmental factors, such as no ceiling, indoor and outdoor temperature that had the potential for breeding places for mosquitoes, no wire net in ventilation, low lighting and high humidity, related to DHF transmission. Vector distibution with entomology index showed that the existence of larvae, eggs and mosquitoes played a role in dengue transmission. The dominant factors affecting the transmission of dengue in Mataram City are the condition of the ceiling and the existence of mosquito eggs in the house.
