New Stony Brook Study Shows More Powassan Virus Risk for Elderly, Highlights Potential Need for Targeted Vaccine
Tick-Borne Disease on the Rise, Study Emphasizes Need for Awareness
Stony Brook University researchers have published a new study in the journal Emerging Infectious Diseases that raises concerns about the increased risk of Powassan virus (POWV) infection for elderly individuals. POWV is a tick-borne flavivirus that can cause severe neurological diseases, including encephalitis and meningitis, and can be fatal in up to 10% of cases.
Key Findings of the Study:
- Researchers analyzed data from 136 POWV cases reported in New York State from 2000 to 2020.
- They found that people over the age of 65 accounted for 64% of all cases, despite representing only 16% of the state's population.
- The study also found that elderly individuals were more likely to experience severe neurological complications and death from POWV infection.
Implications for Public Health
The findings of the Stony Brook study highlight the need for increased awareness about POWV, especially among elderly individuals. The study suggests that targeted vaccination efforts may be necessary to protect this vulnerable population.
Recommendations for Prevention:
- Use insect repellent containing DEET or picaridin when spending time outdoors.
- Wear long sleeves and pants when in wooded areas.
- Check for ticks after being outdoors and remove them promptly.
- Get vaccinated against POWV if you live in an area where the virus is known to be present.
Conclusion
The Stony Brook study provides valuable insights into the risk of POWV infection for elderly individuals. The findings emphasize the need for increased awareness, prevention measures, and potential targeted vaccination efforts to protect this vulnerable population from this serious tick-borne disease.
