在巴布亚新几内亚高流行区的一个村庄，研究了未经处理的蚊帐对人类疟疾和丝虫病传播的影响。 在按蚊中，引入蚊帐后恶性疟原虫子孢子抗原阳性率、丝虫感染率和人体血液指标均显著下降。 人与病媒接触的减少并没有影响蚊子的密度，因为无论是在着陆率还是室内休息捕获量方面都没有发现显著差异，房屋中蚊帐的数量和狗的主人是与室内休息蚊子数量减少显著相关的因素。 然而，蚊子中恶性疟原虫子孢子抗原率的降低并不伴随着疟疾寄生虫或针对恶性疟原虫环子孢子蛋白的抗体流行率或滴度的降低。
The impact of untreated bed nets on the transmission of human malaria and filariasis in a village in a hyperendemic area of Papua New Guinea was studied. In anopheline mosquitoes, the Plasmodium falciparum sporozoite antigen positivity rate, filarial infection rates and human blood indices dropped significantly after bed nets were introduced. This reduction in human-vector contact did not affect mosquito density as no significant difference in either landing rates or indoor resting catches was found. The number of bed nets in a house and ownership of dogs were factors significantly associated with a reduction in the number of indoor resting mosquitoes. However, the reduction in the P. falciparum sporozoite antigen rate in mosquitoes was not accompanied by a reduction in either malaria parasite or antibody prevalences' or titres against the P. falciparum circumsporozoite protein.
