The risk of EEE transmission will continue to decrease as we move towards a hard frost. Only a hard frost will eliminate the risk of EEE and WNV within your community. A hard, or killing frost, is defined meteorologically as two consecutive hours of temperatures below 28 degrees Fahrenheit or three hours below 32 degrees. This will occur at different times for different communities, and there may even be variation within communities based on local geography. MDPH has provided a low temperature map to assist communities in their decision making processes for determination of evening fall activities. MDPH will routinely update this resource and provide guidance messaging. Please visit: https://www.mass.gov/info-details/massachusetts-arbovirus-update#tempera...
