After two tele-conferences of the emergency committee by the WHO's Director-General under the International Health Regulations, the committee advised that the Ebola outbreak in West Africa constitutes an "extraordinary event" and a public health risk to other states.
The committee warned that the possible consequences of further international spread are particularly serious in view of the virulence of the virus, the intensive community and health facility transmission patterns, and the weak health systems in the currently affected and most at-risk countries.
It urged a coordinated international response to stop and reverse the international spread of Ebola. The committee advised the states with Ebola transmission to declare a national emergency, ensure immediate and timely information on the situation, take steps to address the outbreak, and provide immediate access to emergency financing to initiate and sustain response operations. Affected states were also advised to establish an emergency operation center to coordinate support across all partners to ensure efficient and effective implementation and monitoring of comprehensive Ebola control measures.
The WHO also required the affected states to conduct exit screening of all persons at international airports, seaports and major land crossings, for unexplained febrile illness consistent with potential Ebola infection, saying that any person with an illness consistent with Ebola should not be allowed to travel unless the travel was part of an appropriate medical evacuation.
The WHO said that any state newly detecting a suspect or confirmed Ebola case or contact, or clusters of unexplained deaths due to febrile illness, should treat this as a health emergency, and take immediate measures to prevent a potential Ebola outbreak. The largest Ebola outbreak ever recorded at present began in Guinea in December 2013, and now involves transmission in Guinea, Liberia, Nigeria, and Sierra Leone.
Statistics from the WHO showed that as of August 4, countries have reported 1,711 cases (1,070 confirmed, 436 probable, 205 suspect), including 932 deaths.
