Bourbon virus detections and first human NY case confirmed in New York
Scientists at Following the July 2026 confirmation of the state’s first human Bourbon virus infection in Suffolk County, health officials have continued to document the pathogen’s presence in New York. On 24 July, Stony Brook Medicine first reported the first detection of Bourbon virus RNA in a lone‑star tick on Long Island, warning collected elsewhere in the state, prompting renewed warnings that expanding tick ranges could increase human exposure. In July 2026, New York health officials confirmed the state’s first human case: 67‑year‑old Michael Larkin, a Suffolk County landscaper, was bitten by two lone‑star ticks in 2021, initially treated for Lyme disease, and later diagnosed with Bourbon virus after specialized testing in 2024. Larkin experienced fever, rash, severe headaches, night sweats and low platelet counts, requiring a five‑day hospital stay before fully recovering. A review of 107 suspected tick‑borne cases from 2019‑2024 found serologic evidence of at least one acute Bourbon virus infection, suggesting the pathogen may be more common prevalent than previously recognized. The virus remains without a vaccine, specific antiviral therapy, or commercial diagnostic test, and its spread is linked to the northward expansion of lone‑star ticks driven by climate and wildlife changes. Authorities continue to call for expanded surveillance, development of clinical testing, and heightened public awareness to prevent further undiagnosed cases. Later in July 2026, same week, Suffolk County officials reiterated the confirmation of Larkin’s Larkin case and highlighted concurrent announced three probable tularemia cases, infections, including a child with a tick‑bite ulcer, underscoring an unusually severe tick season. Public‑health advisories emphasized By 3 August, the use Long Island case was confirmed as the first Northeast U.S. occurrence, and researchers highlighted the parallel emergence of the Asian longhorned tick, whose rapid spread and capacity to transmit multiple pathogens adds further concern for tick‑borne disease surveillance. Authorities continue to call for expanded tick monitoring, development of clinical diagnostics, and public‑health messaging on repellents, protective clothing, and thorough tick checks for people and pets as lone‑star tick populations expand. pets.
