Introduction: The COVID-19 pandemic has caused unprecedented-scale global disruptions in our daily lives. With more than 6 million deaths worldwide, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-caused coronavirus disease 2019 (COVID-19) has had a devastating impact on the world's demography and is now the most significant global health disaster since the 1918 influenza pandemic. Since the beginning of 2020, adjustments to contact and transportation patterns have impacted the seasonal patterns of several infectious diseases around the world, including influenza. The impact of these perturbations can help clarify important epidemiological mechanisms that, after decades of study, remain obscure. The potency and mechanisms that underlie seasonality in transmission, immunity to natural infection's persistence, evolutionary bottlenecks operating during low transmission seasons, and the effect of non-pharmaceutical interventions (NPI) that might be used in influenza pandemics in the future are some of these.

Aim of the Study: The aim of the present study is to understand the severity, morbidity, and variation associated with viral infection influenza post-COVID-19 pandemic.

Methodology: The review is a comprehensive research of PUBMED since the year 2011 to 2022.

Conclusion: Influenza is thought to cause more serious outcomes and complications more frequently. Although it was first believed that our newest foe, COVID-19, would have more severe effects than previous respiratory tract viruses, recent research has once again shown that influenza is not such a benign virus, particularly in youngsters. Despite the fact that social isolation and mask use have reduced the spread of other respiratory viruses, including influenza, influenza vaccination, especially for the elderly, is highly advised following COVID-19 due to the significance of the issue and the potential for serious complications in a population of high-risk or hospitalized patients.
