Curtains with insecticide reduce rates of cutaneous leishmaniasis

Pyrethroid impregnated curtains provide good protection against indoor transmission of leishmaniasis in urban Venezuela. Kroeger and colleagues (p 810) carried out a community randomised trial in urban areas, where indoor transmission of cutaneous leishmaniasis is common. The intervention households were provided with curtains impregnated with insecticide, and the controls had ordinary curtains or none at all. After 12 months, the cumulative incidence of leishmaniasis in the intervention group had fallen from 4% to 0%, whereas in the control group it had increased to 9%. The number of sandflies entering houses was reduced in houses with impregnated curtains.
