    Area of Science:

    • Geriatric Medicine
    • Infectious Diseases
    • Epidemiology

    Background:

    • Influenza A outbreaks pose a significant risk to vulnerable elderly populations in long-term care settings.
    • A specific outbreak of influenza A, resembling A/Victoria/3/75, impacted two geriatric wards in February 1976.

    Purpose of the Study:

    • To document the impact of an influenza A outbreak in geriatric wards.
    • To evaluate the effectiveness of influenza immunization and antiviral treatments in the elderly.

    Main Methods:

    • Retrospective analysis of an influenza A outbreak in two geriatric wards.
    • Observation of patient outcomes, including mortality and morbidity.

    Main Results:

    • Out of 19 patients at risk, 30% were affected by the influenza A outbreak.
    • Three patient deaths occurred during the outbreak.

    Conclusions:

    • Influenza immunization for the elderly, administered before winter, is a simple, inexpensive, and recommended preventive measure.
    • Repeated immunization with inactivated influenza vaccine is a suitable treatment.
    • Amantadine may be effective in the elderly and warrants further investigation.
