Kepadatan Larva Nyamuk Vektor sebagai Indikator Penularan Demam Berdarah Dengue di Daerah Endemis di Jawa Timur

Dengue Hemorrhagic Fever (DHF) is one of the serious health problems in Indonesia.There are always DHF cases every year. East Java is a province with high cases of DHFevery year, with the peak of burden was 86,52 cases per 100.000 people in 2010. Thisstudy, conducted in 2011, was aimed to know the larval density figure and key container inthe dengue endemic areas in East Java. In total, there were 10 villages from three districts(Tulungagung, Malang and Kediri) were surveied. One hundred houses were visualysurveied to count the larvae indices: House Index (HI), Container Index (CI), and BreteauIndex (BI) based on the WHO regulation. Larvae-Free Index based on the IndonesianMinistry of Health regulation was also measured. The larvae indices measured indicatedthat eight villages were categorized as middle risk (density figure 5) and two villages(Bago Village from Tulungagung and Mojoroto Village from Kediri) were categorized ashigh risk (density figure 6). Cement bath tub was the key container of all location. Basedon these results known that three districts were potential for dengue transmission.
