Historical Perspective

• COVID-19, also called Sever Acute Respiratory Distress Syndrome Coronavirus 2 (SARS-CoV-2) originated in Wuhan, China in late December 2019. It has caused a significant morbidity and mortality worldwide and has been declared a global pandemic by the WHO.
• Influenza occurs mainly during the winter, it is a highly contagious acute viral respiratory infection that causes significant morbidity and mortality worldwide.

Differentiating COVID-19 and Influenza co-infection from other Diseases

• Influenza and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. Influenza is caused by infection with influenza viruses and COVID-19 is caused by infection with the coronavirus (SARS-CoV-2). Testing may be needed to help confirm a diagnosis because some of the symptoms of flu and COVID-19 are similar. Influenza and COVID-19 share many characteristics, but there are some key differences between the two.
