VECTOR DYNAMICS SURVEY FOR MALARIA IN CENTRAL KALIMANTAN ,INDONESIA 2011
Malaria is a major health problem in Indonesia with 15 million cases every year and with an estimeted 300,000 death. Kapuas District in Central Kalimantan is considered malaria endemic. There were 2,830 cases notified in 2010 alone. The notification rate for 2010 was 8,36 per 1,000 population. The aim of the survey was to determine the vector dynamics in the District including mosquito type, Main House Density (MHD), biting times and mosquito habitat.
METHODS:
An entamological survey was conducted in two Villages A (rural) and B (semi urban) both had many palm plantation, high rainfall, many migrant worker and high incident rate of malaria infection. Survey had never been conducted in this two villages before. The research instrument to collect mosguitos were a slide, an aspirator, anemometer, hygrometer, PH meters and others.
RESULTS:
Village A had anopeles subpictus species which is a bitting species of low density (MHD = 0.042) with biting time 18:00 and 22:00 hrs. Mosquito habitat were pot holes, fisesh ponds and resting places included inside homes on walls, cupboard and table.Village B had a number of mosquito species, but mainly Anopeles umbrosus (MHD= 0,063), with biting hours of18:00 pm. to 19:00 pm.Mosquito habitat in Village B were similar to Village A,but fewer mosquitos were found.
CONCLUSIONS:
The village in one district had differing entomological dynamics, with differing species and mosquito biting times. This will guide the control measures for larvae control, health promotion for the affected populations and case management. Instruction was given to local health care centres to follow the control measures and to respond to outbreaks.
