It took three months for the WHO to find out there was an Ebola outbreak and five months to declare this a state of emergency.

Authorities in Guinea and the WHO declared on March 24, 2014 that since January the west African country had recorded 87 suspected cases of viral hemorrhagic fever, including 61 deaths. Scientists who were studying samples in the French city of Lyon also confirmed it was Ebola. However, the WHO did not declare the outbreak a ‘public health emergency of international concern’ until August 8, 2014.
In Piot’s opinion the response to Ebola needed to address both the lack of robust healthcare systems and the cultural habits and belief systems prevalent in the affected countries. He also blamed the mass hysteria in North America which led to quarantine of people returning from west Africa as a major deterrent and disincentive for supporting the countries in west Africa.
The Ebola outbreak has claimed 6,070 lives, according to the latest WHO update, with the vast majority of deaths in Liberia, Guinea and Sierra Leone.
