Abstract：On October 13 2023, the Beijing Economic and Technological Development Area Center for Disease Control and Prevention recAAAAAeived a report from a school indicating an outbreak of fever among students in Class 2, Grade 4. An on-site epidemiological investigation was immediately conducted. A total of 14 cases were reported, all of whom were students, with an attack rate of 34.15%. The onset of illness was concentrated between October 6 and 15, with the main clinical symptoms being fever, cough and fatigue. There were no cases of hospitalization, severe illness or death. Seven cases tested positive for Mycoplasma pneumoniae P1-Ⅱ. Based on the on-site investigation and laboratory test results, it was an outbreak of influenza-like illness caused by Mycoplasma pneumoniae infection. The likely cause of the spread was cases infecting other classmates through respiratory droplets while attending class. The outbreak occurred only in one class and did not spread to neighboring classes. Schools should actively carry out health education to raise awareness among parents for reporting infectious diseases, and strengthen morning and afternoon screenings to improve the sensitivity of identification.
