Hypothesis
The risks from infection by West Nile virus exceed the risks from exposure to mosquito insecticides.
Conclusion
The risks from West Nile virus infection are greater than those from mosquito insecticides, contrary to some perceptions.
Supporting Evidence
- The risks from infection by WNV exceed the risks from exposure to mosquito insecticides.
- Adulticiding is unlikely to be completely effective.
- Upstream interventions can reduce the effectiveness of adulticiding.
Takeaway
Getting sick from West Nile virus is more dangerous than the chemicals used to kill mosquitoes, even if some people think the chemicals are more harmful.
Limitations
The analysis may be misinterpreted and lacks data to support the risk-benefit comparison.
