Investigation and management of a campus Hemophilus influenzae clus-ter epidemic
Objective This study analyzed the epidemic characteristics of a campus cluster epidemic caused by Haemophilus influenzae,and explored prevention and control measures,to provide a reference for the prevention and control of such epidemics.Methods We developed case definitions and conducted case searches;conducted case investigations and on-site epidemiological investigations;collected throat swabs for common respiratory pathogen testing;and analyzed the effects of epidemic prevention and control measures and vaccination.Results From June 6 to 19 of 2023,a cluster epi-demic caused by H.influenzae occurred in a primary school in Longgang District,with a total of 15 cases,all in Class 1 stu-dents.The school's incidence rate was 0.67％(15/2 232),and the class's incidence rate was 31.91％(15/47).The cases were in six males and nine females,and no statistically significant difference in incidence rate was observed by gender(x2=1.079,P=0.299).The main clinical symptoms were fever(100％)and cough(80％);the highest fever temperature was 40.0 ℃,and the lowest was 37.4 ℃.The main clinical diagnoses were pneumonia(26.67％)and bronchitis(46.67％).Throat swabs from five cases were collected for RT-PCR testing,and the nucleic acid tests for Haemophilus influenzae were positive in four cases.After implementation of suspension measures,no new cases were observed starting from the fifth day.Conclu-sion Campus cluster outbreaks caused by Haemophilus influenzae are relatively rare.improving awareness and adopting reasonable prevention and control measures can are effective responses for prevention and control of the overall epidemic.
