在印度东北部阿萨姆邦研究了经杀虫剂处理的蚊帐 (ITMN) 对猪和人类乙型脑炎 (JE) 病毒血清转化的影响。干预后，在治疗地点发现人和猪的血清转化率急剧下降。与其他两个地区 Athabari 和 Rajmai 相比，在 Kollolua 地区，ITMN 对人和猪都使用，人类（风险比 [RR] = 0.28。95% 置信区间 [CI] = 0.16-0.49）和猪（RR = 0.21，CI = 0.11-0.40）显着降低，ITMN 只覆盖人类或猪。黄昏期间对牛棚内和周围蚊子种群的监测显示，在研究地点的干预后期间，媒介密度没有显着下降（P > 0.05）。尽管在干预后期间户外潜在的乙型脑炎媒介占很大比例，但通过使用ITMN可以在流行地区实现令人鼓舞的防止乙型脑炎病毒传播的防线。
The effect of insecticide-treated mosquito nets (ITMNs) on Japanese Encephalitis (JE) virus seroconversion in pigs and humans was studied in Assam, Northeast India. A sharp reduction of seroconversion rate in human and pig was found in treated localities after intervention. A marked reduction was achieved in humans (risk ratio [RR] = 0.28. 95% confidence interval [CI] = 0.16-0.49) and pigs (RR = 0.21, CI = 0.11-0.40) in the Kollolua locality where ITMNs were used on both humans and pigs compared with the other two area, Athabari and Rajmai, where ITMNs were covering only either humans or pigs. Monitoring of the mosquito population in and around cattle sheds during dusk revealed no significant decline (P > 0.05) of vector density during the post-intervention period in study localities. In spite of the high preponderance of potential JE vector outdoors during the post-intervention period, an encouraging line of defense against circulation of JE virus through the use of ITMNs can be achieved in endemic areas.
