How do I know if the mosquitoes at my house have Zika, West Nile or St. Louis Encephalitis or some other virus?
- Unless mosquitoes are trapped by Vector Surveillance and tested at the Department of Agriculture, it would be impossible to determine if they are infected with the virus that causes illnesses such as Zika, St. Louis Encephalitis, West Nile or other mosquito-borne viruses.
- Not all mosquitoes are infected but since many can transmit disease it is important to prevent mosquito bites. Use insect repellants and eliminate standing water and mosquito breeding spaces around your home.
- The CDC www.cdc.gov and the Health District www.SNHD.info have information about eliminating mosquito breeding sites and other prevention measures on their websites.
