An 85-year-old man is transferred from an acute care hospital to your long-term care (LTC)...

This elderly resident presents with symptoms suggestive of influenza or another respiratory viral illness shortly after admission to a long-term care (LTC) facility. MCCQE population health objectives emphasize early outbreak prevention in institutional settings. The first and most immediate step when a potentially contagious illness is identified is to isolate the symptomatic individual using appropriate droplet and contact precautions.

Prompt isolation reduces the risk of transmission to other vulnerable LTC residents, who are at high risk of severe complications. Additional steps—such as notifying public health authorities or closing the facility—are considered if an outbreak is confirmed or multiple cases occur. At this stage, there is only a single symptomatic patient.

Immunization during an acute febrile illness is not appropriate and would not provide immediate protection. Therefore, immediate isolation while arranging diagnostic testing and monitoring for additional cases is the correct infection prevention and control measure.
