The use of insecticides to control disease vectors is one of the principal strategies currently employed by public health ministries. Diseases such as malaria, dengue, Zika, chikungunya, yellow fever, and Chagas disease have become important public health problems; the successful use of pesticides depends on their appropriate use in controlling these diseases. It is necessary for operational personnel to understand all the steps in insecticide fogging.
Application of the correct dose of insecticides is an essential factor not only in successfully eliminating vectors, but also in reducing the risk that these vectors will develop resistance to insecticides. The implementation of WHOPES recommendations depends on detailed knowledge of the equipment that should be used during application of insecticides, as well as correct operation, calibration, and maintenance.
To strengthen these actions, PAHO/WHO has produced a series of training videos for vector control program workers in the Region of the Americas. These videos cover personal protective measures and biosafety (before, during, and after insecticide fogging); operation, calibration, and maintenance of public health equipment used for hot and cold fogging; and communication with communities.
