This tick-borne disease, similar to Lyme disease, is transmitted through infected ticks and can cause severe illness in some individuals.

While Powassan virus remains rare, there has been a notable increase in the number of reported cases in recent years, alerting public health authorities. The Centers for Disease Control and Prevention (CDC) has stated that cases in the United States are primarily reported in northeastern states and the Great Lakes region, with the highest activity occurring in late spring, early summer, and mid-fall when ticks are most active.

The CDC emphasizes that all residents and visitors to areas with identified Powassan virus activity are at risk of infection, particularly those engaged in outdoor work and recreational activities. In 2023, there were 44 cases of Powassan virus disease reported in the United States, with Massachusetts accounting for 10 cases, while New Hampshire, Maine, Rhode Island, and Vermont recorded smaller numbers.

Most individuals exposed to Powassan virus may not experience any symptoms, but for some, the disease can lead to severe conditions such as meningitis or encephalitis. Symptoms typically appear within one week to one month after a tick bite and include fever, headache, vomiting, weakness, confusion, loss of coordination, speech difficulties, and seizures. The CDC cautions that approximately one in ten people with severe disease may die, and survivors can experience long-term health issues such as recurring headaches, muscle weakness, and memory problems.

Unfortunately, there are currently no medications available to prevent or treat Powassan virus infection, as antibiotics are ineffective against viruses. Instead, rest, fluids, and over-the-counter pain medications can help alleviate symptoms. Severe cases often require hospitalization for breathing support, hydration, and to reduce brain swelling.

To help prevent contracting the virus, the Massachusetts Department of Public Health advises residents to use repellents containing DEET, wear long, light-colored clothing tucked into socks or boots, stay on designated trails while walking or hiking, and shower immediately after potential tick exposure. Pet owners should also consult with veterinarians regarding tick control options for their pets. Additionally, residents are urged to check themselves, their children, and their pets for ticks after spending time in tick-prone areas.

For further information and guidance, residents can visit the state website, the CDC website, or the Town of Sharon Health Department website. Local residents can also reach out to the Sharon Health Department at 781-784-1500 ext. 1205.

With the emergence of the Powassan virus case in Sharon, it is crucial for individuals to remain vigilant about tick safety and take appropriate precautions to avoid contracting this potentially dangerous disease.
