Timeline of mosquito net distribution
This is a timeline of bed net distribution, a strategy deployed widely to reduce the incidence of malaria in tropical countries.
|Ancient times <||Use of mosquito nets is documented in the Mediterranean world. Evidence also indicates their use in Japan.|
|19th century||British colonists in India adopt sleeping under nets (likely inspired by the example of Punjabi fishermen).|
|1940s||Textiles and insecticides start to be combined, during World War II.|
|1970s–1980s||Contemporary with the decline of DDT-based indoor residual spraying, interest in insecticide-impregnated nets as a malaria control tool reemerges.|
|1990s||Insecticide treated nets (ITN) start to be used early in the decade. By the mid-1990s, ITNs already become an important component of global and national malaria control policies.|
|2000s||Mosquito net distribution develops at a large scale. The number of ITNs delivered by manufacturers to malaria endemic countries in Sub-Saharan Africa increases from 6 million to 145 million between 2004 and 2010. Between 2000 and 2011, the share of households owning at least one treated net in SSA is estimated to have risen from 3% to 50%.|
