WHO recommends Indoor Residual Spraying (IRS) for the prevention and control of malaria in children and adults living in areas with ongoing malaria transmission.
Notes and Remarks
- 1.WHO recommends IRS with a product that has been prequalified by WHO for deployment in most malaria-endemic locations. DDT, which has not been prequalified, may be used for IRS if no equally effective and efficient alternative is available, and if it is used in line with the Stockholm Convention on Persistent Organic Pollutants. IRS is considered an appropriate intervention where:
- the majority of the vector population feeds and rests inside houses;
- the vectors are susceptible to the insecticide that is being deployed;
- people mainly sleep indoors at night;
- the malaria transmission pattern is such that the population can be protected by one or two rounds of IRS per year;
- the majority of structures are suitable for spraying; and
- structures are not scattered over a wide area, resulting in high transportation and other logistical costs.
