Powassan Virus Emerges as a Severe Threat Amid Tick Season: What Thais Need to Know
As the annual tick season approaches in North America, a rare but dangerous virus is attracting mounting attention: Powassan virus. While this tick-borne illness remains uncommon, recent research and rising case reports point to growing concerns that reverberate beyond Western borders—and carry valuable warnings for Thailand as well.
Powassan virus, primarily transmitted by blacklegged ticks, has been recognized as one of the most serious tick-borne diseases in the United States, despite its rarity. Last year, Minnesota reported a record 14 cases, the highest count since 2008 when official recordkeeping began. According to Minnesota Department of Health data, while most years saw fewer than five cases, a slow but concerning uptick has prompted both local and national action. “The risks are relatively low, however, all the tick prevention that you would do to keep yourself from getting one of those more common diseases will also help keep you safe from getting Powassan,” Elizabeth Schiffman, an epidemiologist supervisor at the Minnesota Department of Health, emphasized in a recent interview (Star Tribune).
