Analysis of Influenza Viruses in 78 Imported Cases at Guangxi Ports
This study presents a statistical analysis of the epidemiological characteristics of imported influenza cases detected at Guangxi ports from February 2023 to February 2024,aiming to inform surveillance,prevention,and control strategies for influenza viruses at these ports.A total of 286 inbound individuals exhibiting flu-like symptoms,including cough,sore throat,and fever(≥37.3℃),were sampled for oral and pharyngeal swabs at various Guangxi ports.Influenza was identified in 78 cases,yielding a detection rate of 27.27%.Influenza A was predominant,representing 75.64%of the cases(59 individuals),while influenza B accounted for the remaining 24.36%(19 individuals).The majority of cases were traced back to Thailand,contributing to 64.10%of the total(50 cases).Influenza cases were observed across all age groups,with a notable concentration in the 16-30 and 31-45 age brackets,where 26(33.33%)and 23(29.49%)cases were identified,respectively.No significant gender disparity in influenza virus infection rates was observed.The findings indicate a gradual increase in the incidence of imported influenza cases at Guangxi ports from February 2023 to February 2024,with a primary peak in the winter and spring seasons.Given the predominance of the A H3N2 subtype,it is imperative to enhance health education and awareness campaigns,particularly targeting the demographic groups with higher influenza prevalence.
