Abstract: Influenza, a highly contagious viral infection, affects mainly the nose, throat, bronchi and lungs. It is easily transmitted via droplets through coughing or sneezing. Most will recover within one to two weeks without medical care after infection. For older people and those with certain health conditions, however, it may result in hospitalization or even death. Receiving an annual vaccination is the best way to prevent influenza. This study aims to describe the burden of disease and vaccine prevention among these higher risk groups.
