The use of PCR to help quantify the protection provided by impregnated bednets.
Bednets impregnated with a pyrethroid insecticide are an important recent advance in malaria vector control. Here, Suzanne Gokool, Deborah Smith and Chris Curtis describe how a combination of field work with specially designed huts and DNA fingerprinting of mosquito bloodmeals can be used to help assess whether impregnated bednets would give sufficient protection to prevent infection in areas of intense malaria transmission.
