New Research Methods - Powassan Virus

There is a rare but potentially life-threatening tick borne disease called the Powassan virus and researchers at the University of Massachusetts Amherst have developed a more accurate method of detecting it in ticks. 

Conducting a survey in regions of Cape Cod and Martha’s Vineyard, the researchers used a new "Triplex Real-Time PCR" technology, which proved to be more effective than standard testing. The virus was detected in 33 out of 819 ticks collected, with Truro on Cape Cod showing the highest incidence at about 10%. This heightened accuracy in detection is crucial for assessing the risk of exposure to Powassan virus, which can lead to severe brain infections and meningitis in humans.

While Massachusetts has seen a significant number of Powassan cases compared to other states, human infections have been rare. The new testing method, which reduces the risk of false positives and negatives, offers a more precise understanding of the virus's distribution and prevalence among tick populations. Despite the rarity of Powassan cases, preventive measures such as wearing insect repellent and checking for ticks after outdoor activities remain essential in reducing the risk of transmission.
