Isolation Measures for Rhinovirus
Contact precautions are the primary isolation measures recommended for rhinovirus infections, including hand hygiene, gloves, and gowns when direct contact with respiratory secretions is anticipated.
Transmission Mechanisms
Rhinoviruses are primarily transmitted through:
- Aerosols generated by coughing, sneezing, and nose blowing 1
- Direct contact with respiratory secretions
- Contaminated hands and fomites
Understanding these transmission routes is essential for implementing effective isolation measures.
Recommended Isolation Precautions
Hand Hygiene
- Decontaminate hands after contact with patients or their respiratory secretions
- Use soap and water when hands are visibly soiled
- Use alcohol-based hand rub when hands are not visibly soiled 2
- Hand hygiene is critical as rhinoviruses can persist on hands and surfaces
Personal Protective Equipment
Gloves:
- Wear gloves when entering the room of patients with confirmed or suspected rhinovirus infection
- Change gloves between patients or after handling respiratory secretions
- Decontaminate hands after removing gloves 2
Gowns:
- Wear a gown when entering the patient's room and when contact with respiratory secretions is anticipated
- Change the gown after contact and before providing care to another patient 2
Masks and Eye Protection:
- Wear a surgical mask and eye protection when performing procedures that might generate sprays of respiratory secretions 2
Patient Placement
- Place patients in a private room when possible
- Alternatively, cohort patients with the same viral infection together
- Limit patient movement or transport to essential purposes only 2
Additional Control Measures
- Maintain good personal hygiene, including covering the mouth when coughing and sneezing
- Dispose of oral and nasal secretions safely 2
- Restrict visits from young children due to higher risk of virus transmission
- Restrict healthcare workers with respiratory tract infections from accessing patients 2
Special Considerations
Healthcare Workers
- Healthcare workers should adhere strictly to hand hygiene protocols
- Compliance with hand hygiene is critical but often poor in practice, necessitating additional preventive measures 2
High-Risk Patients
- Implement more stringent isolation measures for immunocompromised patients
- Consider additional precautions for patients at high risk for serious complications from respiratory infections 2
Duration of Precautions
- Maintain precautions for the duration of symptomatic illness
- Rhinoviruses can be shed for prolonged periods, especially in immunocompromised patients
Common Pitfalls and Caveats
Underestimating Transmission Risk: Despite being considered "just a common cold," rhinoviruses can cause significant morbidity in vulnerable populations.
Relying Solely on Hand Hygiene: While important, hand hygiene alone may not be sufficient to prevent transmission. A comprehensive approach including PPE and patient isolation is necessary.
Inadequate Attention to Environmental Cleaning: Rhinoviruses can persist on environmental surfaces, requiring thorough cleaning and disinfection.
Failing to Recognize Severity in Special Populations: Rhinoviruses can cause severe lower respiratory tract infections in immunocompromised patients, infants, and those with underlying respiratory conditions 3, 4.
By implementing these isolation measures consistently, healthcare facilities can reduce the transmission of rhinovirus infections and protect vulnerable patients from potential complications.
