Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by SFTS virus (SFTSV). SFTS patients were prone to invasive pulmonary aspergillosis (IPA), which was directly related to increased mortality. Here, we present a critical case of SFTS complicated by IPA in a previously healthy 58-year-old woman. On day 1, SFTSV and three different Aspergillus species were both detected in the patient's bronchoalveolar lavage fluid and blood through metagenomic next-generation sequencing (mNGS). After 17 days of treatment, the patient was still in poor condition and A. fumigatus was once again detected in her blood through mNGS. Then her family decided to give up treatment because of financial problems and grave prognosis. She was discharged home and died the next day. Medical personnel should be alter to the possibility of IPA in SFTS patients due to its high mortality. mNGS may be used as an auxiliary diagnostic tool and efficacy-monitoring method for suspected SFTS complicated by IPA.
