ABSTRACT
The StudySARS-CoV-2 has generated over 122 million cases worldwide. Non-pharmaceuticals interventions such as confinements and lockdowns started in Chile on March 18th 2020. In Europe, confinements and lockdowns have been accompanied by a decrease in the circulation of other respiratory viruses such as Influenza A virus(IAV), Influenza B virus(IBV) or respiratory syncytial virus(RSV) (1). Although changes in circulation patterns of respiratory viruses have been reported, limited information regarding the southern hemisphere is available where the SARS-CoV-2 pandemic merged with the winter season. We conducted viral surveillance of respiratory viruses and we evaluated their presence and establishing whether they were co-circulating with SARS-CoV-2.
