About this tool

This tool helps clinicians choose isolation precautions for a hospitalized child. You pick the infection group (respiratory, rash or skin, gastrointestinal, meningitis or sepsis, or resistant organisms) and then the infection.

Each result shows the precaution type to add to standard precautions (contact, droplet, airborne, or enhanced contact for C. difficile), how long to keep it, the room needed, and notes for staff and visitors, such as immune staff only and N95 use for measles and chickenpox.

It also covers exposed patients without immunity, the screening of visitors for children with tuberculosis, and when to notify public health. Facility infection prevention policies may be stricter, especially for resistant organisms and COVID-19.

Common questions

How long is a child with measles kept in airborne isolation?

Until 4 days after rash onset, or for the whole illness if immunocompromised. Only immune staff enter, and everyone wears an N95.

How long do pertussis patients need droplet precautions?

Until 5 days of effective antibiotics, or 3 weeks after cough onset if untreated.

Does a child with pulmonary tuberculosis need airborne isolation?

Usually not. Young children with typical pulmonary TB are rarely contagious. Airborne precautions are for cavitary, smear-positive, laryngeal or extensive disease. Visitors should be screened, since an adult is often the source.

Why soap and water for C. difficile?

Alcohol rub does not kill C. difficile spores. Use soap and water and sporicidal cleaning.
