“The results we received this week were from collections that were taken before the county conducted aerial spraying last Saturday,” said Oswego County Public Health Director Jiancheng Huang.
“Although the aerial spray was very effective in reducing some of the targeted mosquito populations, recent surveillance shows that mosquitoes are still there which means that viruses might still be present. We are working closely with the state health department to monitor the situation.”
Huang added that everyone still needs to be vigilant to prevent exposure to mosquitoes. “It is very important that people continue to follow personal protection measures.”
