- Influenza virus and COVID-19 co-infection clinical diagnostic may be difficult as they appear to have similar transmission patterns, clinical manifestations and radiological aspect1.
- Nasal congestion (Nasal tampon) and pharyngalgia, which are not common symptoms of COVID-19, were more prone to appear with co-infected patients1.
- Co-infected patients seemed to have similar outcomes1.
- There is no significant difference in rates of SARS-CoV2 infection in patients with or without other pathogens2.
- Presence of other pathogens may not provide reassurance that patient does not also have SARS-CoV22.
This article comes from 2 articles. First is a case series study published by the Department of Gastroenterology in Tongji Hospital in China on March 20th 2020 in the ‘’Journal of Medical Virology’’. 115 patients were included and confirmed with COVID-19. 5 of them were also infected by influenza virus. They studied the clinical characteristics of those 5 patients; symptoms, laboratory results, duration of stay in the hospital and complications. Second is a research letter done in Stanford Health Care to determine rates of co-infection between SARS-CoV-2 and other respiratory pathogens.
