"We have seen quite a bit of West Nile virus activity and human illnesses in our neighboring states, so we just want to remind people to make sure that they're taking precautions against mosquito bites," said Beth Daly, of the Bureau of Infectious Disease Control. EEE and West Nile virus can cause flu-like symptoms. There have been no cases of either disease in humans in New Hampshire this year. So far in 2018, 29 mosquito batches have tested positive for West Nile virus. “Now is a very high-risk time of the year for these types of infections,” Daly said. “So people should be using insect repellant. They should be wearing long-sleeve shirts and long pants when they go outside.”At the Sandown selectmen meeting Monday night, the board approved spraying for mosquitoes in town. “It's tough this time of year, because you think that it's over until you slap one of them,” said Chairman Steve Brown.It's unclear if Newton will be spraying, but several surrounding towns are said to be considering it.“And the school board is reacting very well to it, too, by sending that notice home to all the parents, giving the parents the option of letting all the kids stay in school during recess if they feel uncomfortable being outside, and we're always cautioning our kids, through recreation and through the town, use mosquito spray,” Brown said.Health officials said it will take two hard frosts to kill off the mosquitoes and eliminate the threat for the year.
