COVID-۱۹ and respiratory tract viral co-infections: Choosing the screening method

The new pandemic pathogen, severe acute respiratory syndrome coronavirus ۲ (SARS-CoV-۲) or Coronavirus disease ۲۰۱۹ (COVID-۱۹), causes a wide range of symptoms that differ from mild cold‐like symptoms to pneumonia and death. This virus has been an international public health emergency since December, ۲۰۱۹ due to its high infectious rate. Beyond the pathogenesis of COVID-۱۹, viral co-infections play a vital role in the occurrence and development of this pandemic by increasing the difficulties of diagnosis, treatment and even the disease symptoms and mortality. Regarding clinical presentation, transmission and coincidence this disease is very similar to Middle East respiratory syndrome (MERS), severe acute respiratory syndrome (SARS) and seasonal influenza which makes it difficult to accurately detect [۱-۳].
