Most feasible nursing-led intervention to reduce mosquito-borne illness transmission:

Mosquito-borne illnesses such as dengue, Zika, West Nile virus, and malaria are transmitted by mosquitoes that breed in standing water. Removing standing water — from containers, tires, gutters, flower pots, and other receptacles — directly eliminates breeding sites and is one of the most evidence-based, cost-effective, and immediately actionable environmental interventions available. It can be taught to individuals, families, and communities by a nurse without special equipment or governmental authorization, making it the most feasible nursing-led intervention. Community advocacy for spraying may be effective but requires coordination with public health agencies and is not nurse-led on its own. Recommending that people stay indoors from dusk to dawn is a behavioral intervention with limited feasibility because many people must work or cannot realistically remain indoors, and it does not eliminate the vector. A universal malaria immunization does not currently exist for widespread use in most endemic regions, and vaccine availability is still limited, making this option infeasible at a community nursing level. Source reduction through eliminating standing water remains the cornerstone of community-based mosquito control and is well within the scope of nursing health education and advocacy.
