Soft tick relapsing fever cases identified in 11 US states over a decade

A surveillance report describes cases of soft tick relapsing fever identified in the United States. The report covers cases found in 11 states during the period from 2012 to 2021. The specific number of cases, the exact states involved, and the methods of case identification are not reported. No information is provided regarding patient demographics, clinical presentation, treatment, or outcomes. The report does not include data on safety, tolerability, or adverse events. Key limitations include the lack of detailed epidemiological data, case definitions, and confirmation methods. The absence of a comparator group or intervention analysis prevents assessment of risk factors or treatment efficacy. This report serves primarily to document the known geographic presence of this condition over a specific timeframe. For clinicians, it reinforces awareness that soft tick relapsing fever has been reported in multiple states, though the clinical relevance for individual patient management is not established by this report alone.
