Today, the Republic of Liberia reached the important milestone of 42 days without reporting a new Ebola case, and we are pleased the World Health Organization was able to declare the end of the country’s current outbreak. We congratulate the people of Liberia on reaching this important marker, and once again pledge our commitment to ending the Ebola outbreak in West Africa and helping to rebuild Liberia and other affected nations. As President Obama said when Liberian President Ellen Johnson Sirleaf visited the White House last month, “We’re proud to partner with you and we intend to see this through until the job is done.” While this milestone is important, the world must not forget that the Ebola outbreak still persists in neighboring Sierra Leone and Guinea. We must not let down our guard until the entire region reaches and stays at zero Ebola cases. And we must all work together to strengthen capacity around the world to prevent, detect, and rapidly respond to outbreaks before they become epidemics.
