A case report of acute Q fever with low-read detection of Coxiella burnetii genome by next-generation metagenomic sequencing

The case presents a 47-year-old man with sudden abdominal pain and fever, but the cause was uncertain. Through metagenomic next-generation sequencing (mNGS) and detecting Q fever antibodies in serum, along with the patient's clinical and epidemiological history, a precise diagnosis was made, enabling timely and proper treatment.
