Clinical Scorecard: Persistence of Monkeypox Virus on Frequently Touched Surfaces in Healthcare Environments
At a Glance
Category
Detail
Condition
Mpox (Monkeypox) caused by Monkeypox virus (MPXV)
Key Mechanisms
MPXV is an enveloped DNA virus with high environmental stability; persistence on surfaces varies by surface type and temperature, influencing fomite-mediated transmission
Target Population
Healthcare workers and patients in clinical settings
Care Setting
Healthcare environments including clinical and diagnostic laboratory settings
Key Highlights
MPXV viability is longer on nonporous surfaces (e.g., intravenous tubing, nitrile gloves) and at lower temperatures (4 °C) with infectious virus detected up to 21 days.
Porous materials like cotton show rapid loss of MPXV infectivity, especially at room temperature (22 °C).
Viral DNA detection does not correlate with infectious virus presence, indicating molecular assays may overestimate fomite transmission risk.
Guideline-Based Recommendations
Diagnosis
Use viral culture or infectivity assays to confirm presence of viable MPXV rather than relying solely on molecular detection of viral DNA.
Management
Implement stringent decontamination protocols targeting nonporous surfaces in healthcare environments to reduce MPXV transmission risk.
Handle and transport clinical specimens with caution considering MPXV stability on surfaces.
Monitoring & Follow-up
Regularly monitor high-touch nonporous surfaces for contamination in healthcare settings, especially at lower temperatures.
Assess environmental contamination using methods that distinguish viable virus from viral DNA.
Risks
Recognize that fomites, particularly nonporous surfaces, can harbor infectious MPXV for extended periods, posing transmission risk to healthcare workers.
Understand that molecular detection alone may overestimate risk due to persistence of viral DNA without viable virus.
Patient & Prescribing Data
Healthcare workers and patients exposed to contaminated clinical surfaces
No direct treatment data provided; emphasis on infection prevention through environmental control and protective measures.
Clinical Best Practices
Prioritize cleaning and disinfection of nonporous surfaces such as intravenous tubing and nitrile gloves in healthcare settings.
Maintain lower temperature storage for specimens to preserve virus viability for diagnostic purposes but ensure safe handling to prevent transmission.
Use combined approaches including viral culture to assess infectious risk rather than relying solely on PCR-based detection.
Educate healthcare workers on the potential for fomite transmission and appropriate use of personal protective equipment (PPE).
