Record Rise in Rare Tick-Borne Virus Cases

Powassan Virus Cases Reach Record High

Fox News senior medical analyst Dr. Marc Siegel recently discussed the significant increase in Powassan virus cases. This rare tick-borne disease has seen 15 reported cases this year, a notable rise following a record 76 cases in 2025. Dr. Siegel emphasizes the importance of checking children for ticks post-summer camp as tick season peaks. Unfortunately, there is no specific treatment or vaccine available for Powassan virus.

Prevention Tips for Tick Season

Dr. Siegel provides practical advice to mitigate tick risks during peak season. These include using insect repellent and wearing protective clothing. It is vital to take preventive measures due to the lack of vaccines and treatments.

Emergence of Bourbon Virus

A new challenge has emerged as Bourbon virus cases have been confirmed in New York for the first time.

This virus, transmitted through the common lone star tick, poses diagnostic challenges. Stony Brook Medicine reports that if the virus becomes more prevalent, diagnosing tick-borne diseases will become more complicated.

History and Impact of Bourbon Virus

Bourbon virus was first identified in Bourbon County, Kansas, in 2014. Only six human cases have been documented since then, with two associated deaths including the original case. Researchers suspect more infections may be undiagnosed due to the lack of commercially available diagnostic tests.

Symptoms and Diagnosis Challenges

Symptoms include fever, fatigue, rash, headache, body aches, and nausea. These symptoms resemble those of other tick-borne infections, complicating diagnosis further. Many healthcare providers are unfamiliar with the virus, increasing the risk of misdiagnosis.

Case Study in New York

Stony Brook Medicine confirmed the first case of Bourbon virus in New York in a patient from Long Island. The patient exhibited severe symptoms, including a significant rise in antibody titers, and was hospitalized. Dense tick populations in the Northeast suggest more cases may be undiagnosed.

Call for Enhanced Surveillance

Researchers underscore the need for expanded surveillance and improved testing to track the spread of Bourbon virus. Accurate diagnosis is critical to developing effective treatments.

Tick Prevention Measures

The Centers for Disease Control (CDC) reports the lone star tick is widespread in the Northeast, South, and Midwest. Experts recommend wearing long pants and sleeves, using insect repellent, and avoiding overgrown areas to prevent tick bites.

Key measures include wearing protective clothing like long pants and boots, applying insect repellent to clothing and gear, and staying on well-beaten trails. Check for ticks after outdoor activities and seek medical attention if symptoms develop post-bite.
