Suffolk monitors mosquito populations for disease threats

Suffolk County has reported a significant increase in West Nile virus activity this year, with 229 positive mosquito samples and 16 human cases, marking one of the highest years since 2000. The health department has been actively monitoring mosquito populations to identify potential disease carriers. The presence of mosquitoes in late September indicates ongoing risks for the community, particularly for individuals over 50 years old, who are at greater risk of severe illness. Surveillance efforts include trapping and testing mosquitoes, with a focus on species that can transmit the virus from birds to humans. Entomologist Christopher Romano has been instrumental in separating and identifying mosquito species collected from traps. The samples are sent to the Wadsworth Center lab in Albany for testing. The results inform decisions on whether to implement spraying measures to control mosquito populations. The county has utilized trucks for spraying in specific areas to mitigate the risk of disease transmission. Experts warn that the changing behavior of mosquitoes could lead to increased risks in the future, as they adapt to environmental changes. The Culiseta melanura species, prevalent in red maple swamps, plays a crucial role in the virus's lifecycle, highlighting the interconnectedness of wildlife and human health. The ongoing monitoring and response efforts are vital in managing the public health threat posed by these insects. Overall, the situation underscores the importance of continued vigilance and public awareness regarding mosquito-borne diseases, especially as the season extends into the fall months.
