Upsurge of Powassan virus disease in northeastern United States: a public health concern-a short communication.

Powassan virus (POWV) is a tick-borne Flavivirus primarily transmitted through ticks in North America which is a significant public health threat in the northeastern United States. POWV infection spans from Ontario to the Mid-Atlantic, Northeast, and Midwest regions in the USA. Climate change, ecological factors, and human-related changes, including shifts in migration and agriculture, contribute to the dissemination of POWV. Symptoms include sore throat, fatigue, headache, and severe neuroinvasive conditions. Specialized attention is required for diagnosing and managing. MRI scans detect central nervous system abnormalities, while neuromonitoring identifies metabolic distress. Severe cases may necessitate ICU hospitalisation with continuous monitoring. Prevention measures, such as awareness, controlling mammals, and protecting pets, reduce POWV infection risk. The recent outbreak of POWV in Maine, USA, highlights the importance of worldwide collaboration for prevention. With the global prevalence of POWV increasing due to climate and socioeconomic changes, implementing preventative measures and promoting awareness are crucial in reducing infection risk.
