The Powassan virus, a rare tick-borne illness, is spreading rapidly across the United States, with diagnoses reaching a record high, posing significant public health concerns.

❓ WHAT HAPPENED: The United States has experienced a significant rise in cases related to arare tick-borne disease, with a record number of over 70 diagnoses. 📰 DETAIL: The number of cases related to the Powassan virus, a rare tick-borne and potentially fatal disease, has spiked in the United States. According to the Centers for Disease Control and Prevention (CDC), 76 people have been diagnosed with the disease in the United States, a record high. Prior to 2025, only around seven or eight people were diagnosed each year in the country. The virus, first identified in 1958 in a town near Ontario, Canada, is transmitted through the bite of infected woodchuck or deer ticks. The Powassan virus is most active during late spring and through mid-fall, coinciding with the seasonal increase in ticks. Powassan incubates between one and four weeks and transmits in a matter of minutes, making it particularly dangerous and hard to contain. Early symptoms include weakness, fever, headache, and vomiting. The virus is also known to cause loss of coordination, confusion, speaking difficulties, and even seizures. Powassan can also lead to severe neurological issues such as meningitis and encephalitis. Approximately 10 percent of Powassan cases involving severe neurological problems are fatal. However, some patients are entirely asymptomatic, making it even harder to track. 💬 KEY QUOTE: “One of the most dangerous aspects is its rapid transmission… Powassan can be transmitted in as little as 15 minutes after the infected tick bites, while Lyme disease usually requires a 36- to 48-hour attachment time for transmission,” said Dr. Jorge P. Parada, a medical advisor at the National Pest Management Association. 🎯 IMPACT: There are currently no vaccines or medications for the Powassan virus. While it can infect anyone, children, older adults, and immunocompromised individuals are particularly vulnerable to the virus. The rise in Powassan coincides with a rise in cases related to the flesh-eating New World screwworm. In early June, four new cases involving the flesh-eating parasite, once thought to have been eradicated in the United States in the 1960s, were confirmed. The increase in once-seemingly eradicated diseases will require a multi-front initiative from the Department of Health and Human Services. |
