Ebola virus retains infectious viability on contaminated surfaces for multiple days
Scientific evidence confirms that the Ebola virus can maintain infectious viability on certain contaminated nonporous surfaces for multiple days (up to 192 hours).
The claim is specific, empirical, and testable. Paper [0] directly evaluates the environmental persistence of the Ebola virus Makona variant and finds that it persists on steel and plastic surfaces for 192 hours (8 days), which directly supports the claim that it retains infectious viability for multiple days. Paper [3] also confirms persistence up to nearly 72 hours (3 days) on certain materials. Papers [1], [2], [4], [5], [6], [7], [8], [9], [10], and [11] concern either different viruses, general reviews, or non-Ebola pathogens, rendering them tangential.

The study demonstrates that the Ebola virus Makona variant persists on steel and plastic surfaces for up to 192 hours (8 days), which is multiple days.

The research shows that Ebola-Makona virus can persist on personal protective equipment and materials for up to nearly 72 hours under specific temperature and humidity conditions.
