What is "typhoid fever" in ancient medicine in China?

The so-called "typhoid fever" in ancient Chinese medicine and "intestinal typhoid fever" in modern medicine are completely different concepts. "Typhoid fever" in ancient Chinese medicine refers to acute diseases (including some acute infectious diseases) with fever as the first symptom. Su Wen Re Lun once said: "Those who are hot today are all typhoid fever and the like." "Difficult Classics" records: "There are five types of typhoid fever: stroke, typhoid fever, damp heat, fever and fever." It shows that the "typhoid fever" referred to by the ancients includes a wide range.
