摘要
Coronavirus disease 2019(COVID-19)occurs in the influenza season and has become a global pandemic.The present study aimed to examine severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)co-infection with influenza A virus(IAV)in an attempt to provide clues for the antiviral interventions of co-infected patients.We described two patients who were co-infected with SARS-CoV-2 and IAV treated at Wuhan Union Hospital,China.In addition,we performed a review in PubMed,Web of Science and CNKI(from January 1 up to November 1,2020)with combinations of the following key words:“COVID-19,SARS-COV-2,influenza A and co-infection”.A total of 28 co-infected patients were enrolled in the analysis.Of the 28 patients,the median age was 54.5 years(IQR,34.25–67.5)and 14 cases(50.0%)were classified as severe types.The most common symptoms were fever(85.71%),cough(82.14%)and dyspnea(60.71%).Sixteen patients had lymphocytopenia on admission and 23 patients exhibited abnormal radiological changes.The median time from symptom onset to hospital admission was 4 days(IQR,3–6),and the median time of hospital stay was 14 days(IQR,8.5–16.75).In conclusion,patients with SARSCOV-2 and IAV co-infection were similar to those infected with SARS-COV-2 alone in symptoms and radiological images.SARS-COV-2 co-infection with IAV could lead to more severe clinical condition but did not experience longer hospital stay compared with patients infected with SARSCOV-2 alone.
