background and reasoning
Vector control by the NHS includes the rational use of insecticides in prevention, control and emergency situations. Public health use of insecticides involves establishing a surveillance program to monitor resistance levels of local vector populations.
Therefore, monitoring of insecticide resistance is an essential part of entomological surveillance, and together with information on the abundance of adult and immature mosquitoes, as well as on the ecology and habits of vector populations, it helps to make decisions for effective vector control.
Countries in the Region of the Americas face transmission of important vector-borne diseases such as dengue, Zika, chikungunya, leishmaniasis and malaria viruses.
Thus, to ensure the best efficacy of the insecticides used, systematic monitoring of their vector sensitivity must be maintained through standardized methodologies, which have been developed by the World Health Organization (WHO) and the US Centers for Disease Control (CDC). Resistance assessment methodologies.
