Abstract：Fever is a common pathophysiological response of the body to foreign pathogens or substances,and it is also one of the most important clinical manifestations in the progression of diseases.The diagnosis of fever of unknown origin(FUO)is a clinical challenge,and infectious diseases(ID)are among the most common causes of FUO.Through diagnostic techniques in microbiology,the occurrence and nature of infections can be rapidly determined.The latest diagnostic technologies have accelerated the identification of pathogenic microorganisms and antimicrobial susceptibility analysis,enabling early disease assessment,precise treatment,and facilitating the rapid recovery of patients.This article reviews the causes of FUO,infectious diseases that cause fever,microbio-logical diagnostic methods,and research progress,aiming to provide reference for the accurate and rapid diagnosis of FUO.
