Key result
Post-Ebola surveillance strengthening activities in Liberia improved the non-polio acute flaccid paralysis rate from 1.2 per 100,000 in 2015 to 4.3 per 100,000 in 2017.
Why the study?
During the Ebola outbreak, Liberia experienced a significant drop in acute flaccid paralysis surveillance indicators, putting the country at high risk of poliovirus outbreaks.

Absolute Event Rate: 4.3% vs 1.2%
Implementation of enhanced surveillance strategies and new technologies successfully restored acute flaccid paralysis surveillance indicators in Liberia post-Ebola outbreak.
Clarke et al. (2019) conducted an observational in Acute flaccid paralysis. Post-Ebola AFP surveillance strengthening activities vs. 2015 baseline was evaluated on Non-polio AFP rate per 100,000 population under 15 years. Post-Ebola surveillance strengthening activities in Liberia improved the non-polio acute flaccid paralysis rate from 1.2 per 100,000 in 2015 to 4.3 per 100,000 in 2017.
