The UN has been reforming parts of the emergency health system for years, including its health agency -- the World Health Organization (WHO). The Ebola epidemic in West Africa showed that WHO’s response to emergencies needed to be improved quickly. Ebola was discovered in Guinea in March 2014. But it was not until five months -- and many deaths -- later that WHO said Ebola was an international public-health emergency. The aid group Doctors Without Borders has been sharply critical of WHO’s response to Ebola. More than 11,000 people were killed by the disease before December 2015. Joanne Liu is the president of Doctors Without Borders. She said she is pleased that a new plan has been announced. But, she says, it must be followed by action. “The creation of the new WHO Health Emergencies Program is a positive step forward, but we know there is no quick fix,” she said. “There is no cheap fix.”
