Although mosquitos might not be flying around right now, West Nile virus peaks at the end of the summer and early fall. Spread through mosquito bites, symptoms can range from a mild headache to disorientation.

There remains only one recorded case of Eastern equine encephalitis, the rare but potentially deadly disease known as EEE, first reported last month.

Two women who’ve contracted West Nile virus have brought the total number of cases in Massachusetts to 15 this year, officials announced Friday afternoon. One woman is in her 60s, the Massachusetts Department of Public Health said. She was most likely exposed in Middlesex County.

Over the summer, cases of EEE spread across New Hampshire, Massachusetts, and other New England states, each also breaking records for the region.

A woman in her 60s was exposed to the mosquito-borne illness in Middlesex County, and a woman in her 70s was probably exposed while out-of-state, officials said.

Health and environmental officials in Rhode Island and Massachusetts are reminding people to keep protecting themselves from mosquito bites, as the risk of transmitted diseases remains.

Since Aug. 7, 16 Suffolk residents have tested positive for West Nile, the second highest number of human cases in a single year since the county began reporting cases in 2000, the county said.

The Massachusetts Department of Public Health is reporting that two women have been diagnosed with West Nile Virus in Massachusetts.
