A case of clustered influenza A in a pediatric ward.

Children with low immunity and weak resistance are at high risk for influenza, and infection with the influenza virus can be life-threatening in severe cases. This article reported on the investigation and management of a clustered of influenza A cases in a pediatric ward. The clustered influenza A cases were caused by a community-infected influenza A chaperone who was the source of infection, and was most likely spread in close proximity through droplets or aerosols in the same hospital ward. This person caused the influenza A hospital-acquired infections in 2 children (aged 11 months and 12 months, respectively) in the hospital. After taking timely case management and ward management, the prognosis of the three infected patients was good and there was no outbreak of influenza-like illness in the pediatric ward. It is recommended that during the peak of the influenza season, air disinfection should be strengthened and windows should be opened for ventilation in medical institutions, while patients and accompanying staff should be strengthened to wear masks and other publicity, and influenza vaccination should be encouraged, so as to reduce cross-transmission and prevent outbreaks of hospital-acquired infections.
