Abstract

Background: Malaria, caused by the genus Plasmodium, is still a global health problem. Its transmission and spread are strongly influenced by the presence of the Anopheles vector. One of the efforts to reduce cases is the distribution of long-lasting insecticide-treated nets to the residents of malaria-endemic areas. This study aims to measure the density of mosquitoes perched on insecticide-treated bed nets after three years of usage. Method: A cross-sectional study was conducted to observe mosquitoes perching on insecticide-treated bed nets at night and calculation of mosquito density data in units of mosquitoes/LLINs/hour. Results: The number of mosquito bites before bedtime in respondents reached 72.5%, while the number of bed nets infested with mosquitoes reached 74.4%. The density of mosquitoes perched varied between 1 and 10 mosquitoes/LLINs/hour with the highest density proportion of 3 mosquitoes/LLINs/hour. Conclusion: LLINs that have been used for three years were found to be less effective at killing and preventing mosquitoes. It is advisable to re-dip with the insecticide doses to match the local vector susceptibility level by officer assistance so that the mosquito nets still function properly

印度尼西亚Purworejo区Ngadirejo村疟疾再消除地区使用三年长效驱虫蚊帐后的蚊帐小时密度

背景：由疟原虫属引起的疟疾仍然是一个全球性的健康问题。它的传播和传播受到传播媒介按蚊的强烈影响。减少病例的努力之一是向疟疾流行地区的居民分发长效驱虫蚊帐。这项研究旨在测量使用三年后栖息在经过杀虫剂处理的蚊帐上的蚊子的密度。方法：进行一项横断面研究，观察蚊子夜间栖息在经过杀虫剂处理的蚊帐上，并计算蚊子密度数据，单位为蚊子/LLINs/小时。结果：被调查者睡前被蚊虫叮咬的次数达到72.5%，蚊帐被蚊虫侵扰的次数达到74.4%。栖息的蚊子密度在1至10只蚊子/LIN/小时之间，最高密度比例为3只蚊子/LIN/小时。结论：使用三年的LLIN在杀灭和预防蚊子方面效果较差。建议在官员的协助下重新浸泡杀虫剂剂量，以匹配当地媒介的易感性水平，从而使蚊帐仍能正常工作

期刊介绍： Journal of Communicable Diseases (E-ISSN: 0019-5138 & P-ISSN: 2394-7047) is published by ADR Publications and is the official publication of Indian Society of Malaria and Other Communicable Diseases. Journal of Communicable Diseases covers scientific researches in the field of communicable diseases. Accept articles with scientific excellence in the form of (1) Original articles in basic and field research (2) Critical reviews, (3) surveys, (4) Case studies, (5) opinions/Correspondence/letters to editor, etc. The first issue of the publication entitled “Bulletin of the National Society of India for Malaria and Other Mosquito-Borne Diseases” the precursor of “Journal of Communicable Disease” (J Commun Dis) was brought out in 1953. The objects and purposes of J Commun Dis are: • to advance knowledge regarding the cause, prevalence, epidemiology, treatment, prevention and control of malaria and other-mosquito-borne diseases and other communicable diseases, • to stimulate scientific and practical interest among individuals and organizations in the prompt and effective application of treatment and control methods, • to integrate scientific and field activities and co-ordinate various scientific investigations, • to disseminate such knowledge both to scientists and to the general public.
