Powassan Virus Spreading in Concentrated Clusters in New England, Experts Warn
A new study by the Yale School of Public Health finds that the tick-borne Powassan virus is being transmitted in concentrated community clusters throughout New England. The virus now appears to be moving slowly or staying put, simmering in specific hotspots, and evolving independently in each one. This new information could help health officials to target hotspots—where Powassan is more likely to spill over into humans—for education and eradication efforts.
