Scientists in China report finding a previously described tick-borne virus, Asian longhorned tick nairovirus, after testing people with mysterious illnesses.

According to the research described by multiple outlets, investigators examined thousands of patients who had tick bites and found the virus in a minority of cases. Fox News reports positivity in more than 10% of tick-bitten patients studied, while the Post cites a specific figure of 10.4% among more than 3,000 such patients.

The reported illness associated with the detection includes flu-like symptoms, and the studies also describe blood-related findings, including thrombocytopenia in some patients. The outlets focus on the overall discovery and the proportion of positive cases, without detailing clinical management or broader implications beyond the identification of the virus and its apparent association with symptoms in tick-bitten patients.
