In early August, the Health Department launched its annual larvicide application program to reduce the mosquito population and prevent West Nile Virus (WNV) and other mosquito-borne diseases. Through this program, larvicide is applied to storm drains and various standing water locations around the city to prevent mosquito eggs from hatching.
This step is important in preventing WNV, because people get the virus through mosquito bites. Chances are low that a person would become ill from a single mosquito bite. In fact, most people who are infected with WNV experience no symptoms at all. Still, the virus can cause serious illness in some people, especially those older than 50 years old. Symptoms include high fever, headache, neck stiffness, vomiting, diarrhea, rash, and/or disorientation. According to state officials, there were six reported cases of WNV infection in Connecticut residents last year.
The larvicide program is just one part of the Health Department’s WNV protection strategy: reduce sources of mosquitoes, control mosquito larvae (mosquitoes that haven’t yet grown into adults), work with the state to monitor the mosquito population, and spread the word to Norwalk residents about ways to protect themselves.
