Sun-loving humans aren't the only species basking in the unseasonably warm March weather.
Health officials say the high temperatures are allowing ticks and mosquitoes, which are usually kept in check at this time of year by freezing weather, to activate much earlier than usual.
The combination of more ticks and more people outdoors has led to some early cases of tick-related diseases and is prompting health officials to urge precautions.
They are expecting a bad season for tick-related illnesses this year, said Dr. Lucas Wolf, an infectious disease specialist at Beverly (Mass.) Hospital.
Tick-related illnesses don't usually arise until May in the Northeast or upper Midwest.
