COVID-19 is caused by the Severe Acute Respiratory Syndrome (SARS) coronavirus (Cov)-2, an enveloped virus with a positive-polarity, single-stranded RNA genome. The initial outbreak of the pandemic began in December 2019, and it is affecting the human health of the global community. In common with previous pandemics (Influenza H1N1 and SARS-CoV) and the epidemics of Middle east respiratory syndrome (MERS)-CoV, CoVs target bronchial and alveolar epithelial cells.

In this Journal, Tang et al. have report the symptoms of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection appear very similar to influenza (1). We would like to share our findings for co-infection of SARS-CoV-2 and influenza virus. In December, 2019, a novel coronavirus (SARS-CoV-2) caused Coronavirus disease 2019 (COVID-19) in Wuhan City, Hubei province, China (2, 3).
