Seasonal influenza is a highly contagious airborne disease that manifests as an acute febrile illness with variable degrees of systemic symptoms, ranging from mild fatigue to respiratory failure and death. Influenza causes significant loss of work days, human suffering, and mortality. This year, the flu season's overlapping with the ongoing COVID-19 pandemic represents a major concern.
Worldwide, influenza causes as many as 650,000 deaths annually. The US Centers for Disease Control and Prevention (CDC) documented that seasonal influenza was responsible for 24,000-62,000 deaths during the 2019-2020 season.
