Mosquito surveillance is a critical component of public health efforts to monitor and control mosquito-borne diseases such as malaria, dengue fever, Zika virus, and West Nile virus. Surveillance activities involve monitoring the population density, distribution, and species composition of mosquitoes in a particular area. This information helps public health authorities to identify high-risk areas, track the spread of diseases, and implement targeted control measures such as insecticide spraying or larviciding. Surveillance data can also inform risk assessments and guide decisions on resource allocation for disease prevention and control efforts. Mosquito surveillance may involve trapping and collecting mosquitoes in different habitats, identifying species, testing them for pathogens, and analyzing data to identify trends and patterns related to disease transmission. Surveillance efforts often rely on a combination of traditional methods such as trapping and counting mosquitoes, as well as newer technologies such as molecular techniques and geographic information systems (GIS) mapping. Overall, mosquito surveillance plays a crucial role in protecting public health by providing early warning of disease outbreaks and guiding effective control strategies to reduce mosquito-borne illness transmission.
