[Survival of Marburg virus infectivity on contaminated surfaces and in aerosols]
Voprosy Virusologii
|January 1, 1996
Abstract:
Marburg virus was shown to survive for up to 4-5 days on contaminated surfaces. In aerosol it was not stable, the specific rate of its inactivation being 0.05 min-1. This brought the authors to a conclusion that a relatively close contact is needed for virus transmission from man to man, although the possibility of aerosol transmission of the infection may be appreciably increased in case of the hemorrhagic syndrome with a high level of viremia.
Insights
Marburg virus can survive on surfaces for days but is unstable in aerosols. Close contact is likely needed for transmission, though aerosol spread may increase with severe illness and high viral load.
Area of Science:
- Virology
- Infectious Disease Epidemiology
Context:
- Understanding Marburg virus (MARV) transmission dynamics is critical for public health interventions.
- Previous studies have focused on direct contact, but environmental and aerosol transmission require further investigation.
Purpose:
- To assess the environmental stability and aerosol inactivation rate of Marburg virus.
- To evaluate the implications of these findings for Marburg virus transmission routes.
Summary:
- Marburg virus demonstrated significant survival (4-5 days) on contaminated surfaces.
- The virus exhibited instability in aerosol form, with a specific inactivation rate of 0.05 min-1.
- Transmission likely requires close contact, but aerosol transmission risk may rise with hemorrhagic syndrome and high viremia.
Impact:
- Findings suggest environmental contamination is a potential, albeit secondary, transmission route.
- Highlights the importance of surface disinfection and contact precautions.
- Indicates that aerosol transmission, while less likely, can be amplified during severe symptomatic phases of Marburg virus disease.
