Mosquito net use is an essential part of malaria prevention. Although previous research has shown that many people sleep under a mosquito net in endemic areas, it is unknown whether people underestimate how common it is to sleep under a net every night. Furthermore, perceived social norms about whether most others sleep under a mosquito net every night may contribute to personally sleeping under a net, given decades of research showing that people often mimic others’ behaviours.
This modelling framework is appropriate and provides useful approaches to understanding the effect of mosquito nets for targeting malaria control intervention.
Papua New Guinea (PNG) is a highly malaria endemic country in the South-West Pacific with a population of approximately 6.6 million (2009). In 2004, the country intensified its malaria control activities with support from the Global Fund.
The results of this study suggest that net use would increase in Ghana if coloured nets were made available in mass distributions as well as in the commercial market;
The model describes the ITN market in a typical developing country and is applied to the situation in Tanzania, where the Tanzania National Voucher Scheme (TNVS) provides a targeted subsidy to vulnerable population groups by means of a discount voucher.
Four rounds of MDA with diethylcarbamazine citrate (DEC) and albendazole were given to 8 study villages over an 8-year period. Although annual MDA was not administered for several years the overall prevalence of microfilariae declined significantly from 20.9% in 2002 to 0.9% in 2009.
The findings of this review should be considered highly tentative until such time as greater quantities of dedicated, well-designed and reported studies are available in the published literature.
Whilst household income is the strongest determinant of mosquito net ownership, selected knowledge elements are associated with net use. It is necessary to improve financial accessibility to nets and to communicate that malaria is a disease transmitted by mosquitoes that could be fatal in children.
