The World Health Organization reported West Africa free of the Ebola virus on Jan. 14, 2016, bringing an end to the outbreak that began in 2013.

NOTE: One day later, on Jan. 15th, a new case was reported in Sierra Leone and was categorized as a “flare-up” and was not unexpected by the health care community.

Since Sept. 2014, the Tackle Ebola campaign – funded by philanthropist and entrepreneur Paul G. Allen — has worked to mobilize public, corporate, humanitarian and political support for getting to zero cases of Ebola in West Africa. Celebrities, sports stars, health and advocacy organizations, governments and corporations have joined and supported the campaign.

And by thousands of people who donated their time and money to the campaign and supported our efforts by sharing our messages and wearing the Ebola ribbon.

Thank you to all those who helped get to zero cases of Ebola.

In the coming months, we will be ending the campaign and closing down our digital and social platforms.

Tackle Ebola has been just one part of Paul G. Allen’s commitment to end the outbreak. Mr. Allen has been a leader in the fight against Ebola, committing $100 million and developing a program that brought strategic and targeted solutions to the global response to the outbreak.

While this outbreak has ended, there is still more work to be done to predict and prevent epidemics in the future. Learn more about the Paul G. Allen Ebola Program >>
