Influenza is responsible for several thousand deaths each year. Individuals over the age of 65, residents of long-term care facilities, and patients with long-term health problems (i.e., diabetes, HIV or AIDS, heart dis-ease, kidney disease, lung disease, cancer) are at highest risk for severe influenza and complications. Yearly vaccination can prevent influenza infection and minimize the severity of symptoms in those who do contract this disease. However, infection can occur in immunized persons, because influenza viruses mutate rapidly and may not be covered by a particular year’s vaccine. The following drugs are used in the treatment of influenza strains A and B and in some cases other viral infections.
