I often write about Lyme disease, the most widely-known tick-borne illness. Central Mass residents also face another serious threat. Potentially deadly, Powassan is on the rise in Massachusetts.
The CDC reports that Massachusetts had 22 confirmed cases of Powassan virus from 2009-2018, third highest in the nation. Only Minnesota and Wisconsin had higher reported cases in that time span. In August, another Powassan case was reported in Massachusetts. Neighboring Connecticut has had four confirmed cases of Powassan so far in 2019. The most recent was October 11.
How is Powassan spread?
The black-legged tick, also known as the deer tick, spreads Powassan. Deer ticks feed on the blood of mice and birds, and even our cats and dogs. This makes Powassan virus a true threat to our pets, as well as our human family members. It is reported that mice can even carry infected ticks into our homes. We must remain vigilant, even in the cool autumn weather, in keeping our tick control treatments going. Your family’s health could depend on it!
What are symptoms of Powassan? Are there treatments?
Symptoms of Powassan can take on those of encephalitis or meningitis – brain or spinal cord infections. If you have found a tick on your skin or clothing, or on your pets, and begin to see symptoms of lethargy, headache, fever, confusion, or seizures, seek medical help immediate. There is no treatment for Powassan. Patients typically require respiratory assistance, and treatment for infection of the brain or spinal cord. There is no vaccine to prevent Powassan. Approximately 10% of those infected will die of the disease.
What tick control and prevention measures should you take to prevent Powassan?
If you are going to be outdoors, wear long sleeves and pants in light colors, so you can spot a tick easily if it gets onto your clothing. Use personal tick protection measures – repellents with DEET or permethrin are essential if you are hunting, hiking, performing yard work, or other outdoor activities we love in the fall, such as attending or hosting bonfires. Ticks are still lurking, ready to latch on for their blood meals.
Continued tick control in Central Mass
As I mentioned before, now is not the time to halt the tick control efforts around your home. Even though fall has brought cool temps, it has not eliminated the tick population. Nor are they becoming dormant, as they do in the winter. Tick control around your Central Mass home should continue until the immediate threat is gone – when temps fall consistently below 45°F.
Once ticks become dormant, yard sprays are not essential, but it is wise for Central Massachusetts residents to employ additional tick control with tick tubes. Tick tubes are placed around your property, and are filled with cotton that has been coated with insecticide. Mice will use the treated cotton to build their nests. While the insecticide doesn’t hurt the mice, it will eliminate ticks that try to feed on them – or ticks that are lying dormant in their nests. Tick tubes can greatly reduce the ticks in your yard next spring by breaking their life cycle.
