What is one purpose of mosquito testing?

• A. It provides early indication of activity and information on vector species and infection rates
• B. It replaces clinical surveillance
• C. It eliminates the need for traps
• D. It is always quick and inexpensive

Answer: (A)

Mosquito testing is used to monitor when and where mosquitoes are active and to learn which species are present and whether they carry pathogens. This gives an early signal of transmission risk, allowing targeted actions before human cases appear. The information from testing helps identify which habitats or species to focus on, guides the design of control measures, and tracks how vector populations and infection rates change over time to evaluate interventions. It does not replace clinical surveillance—the data from people who become ill are still essential for understanding disease impact. It also doesn’t eliminate the need for traps, since collecting mosquitoes is how testing is done. And it isn’t always quick or inexpensive; lab processing takes time and resources, so testing is one component of a broader surveillance strategy.
