WASHINGTON — Health experts are warning about the potential spread of a tick-borne disease called the Powassan virus in the summer, as warmer winters have increased the tick population. <br /> <br />The Powassan virus is a potentially life-threatening disease transmitted by ticks, including the deer tick, which is also the primary vector of Lyme disease. <br /> <br />Although most people will not develop symptoms, about 15% of those who do will die, at least 50% of the survivors will have long-term neurological damage, and the rest may have symptoms including fever and headache. <br /> <br />According to the Centers of Disease Control and Prevention, there are no vaccines to prevent or medications to cure an infection of the Powassan virus.
