A rare tick-borne illness known as Bourbon virus has been identified for the first time in New York after a Suffolk County resident contracted the virus through tick bites while working outdoors. Michael Larkin, 67, was bitten by two lone star ticks, which transmitted the infection.

Bourbon virus is a viral disease transmitted by ticks, with symptoms that closely resemble those of other tick-borne illnesses such as Lyme disease. Due to its rarity and symptom overlap, it can be difficult to diagnose accurately. In Larkin’s case, initial treatment targeted Lyme disease, involving antibiotics that proved ineffective against the Bourbon virus. As the infection progressed, he experienced symptoms including rash, fever, night sweats, and intense headaches.

Other common symptoms of Bourbon virus infection may include fatigue, body aches, nausea, and vomiting. Larkin required a five-day hospitalization before making a full recovery. However, the illness has been associated with severe outcomes in some cases.

Bourbon virus remains uncommon, with the greatest number of reported cases occurring in Midwestern states including Kansas, Oklahoma, and Missouri, averaging fewer than one case annually. Despite its rarity, two confirmed cases in that region have resulted in fatalities. There is currently no vaccine to prevent Bourbon virus infection, no commercial diagnostic test, and no approved antiviral treatment.

Health officials emphasize the challenges posed by the disease due to its nonspecific symptoms and the absence of targeted therapies. The emergence of Bourbon virus in New York underscores the importance of awareness among healthcare providers and the public about tick-borne illnesses beyond the more widely recognized diseases.
