The Zaire strain of the virus survives the longest on glass surfaces stored at 39 fahrenheit, up to 50 days, and can remain alive on dry surfaces such as doorknobs and tables for several hours. The survival period is extended in moist environments, such as mucus. Researchers:
This study has demonstrated that ﬁloviruses are able to survive and remain infectious, for extended periods when suspended within liquid and dried onto surfaces. Data from this study extend the knowledge on the survival of filoviruses under different conditions and provide a basis with which to inform risk assessments and manage exposure.
