31 July 2014-Ebola virus disease update, West Africa

Epidemiology and surveillance

Between 24 and 27 July 2014, a total of 122 new cases of Ebola virus disease (EVD; laboratory-confirmed, probable, and suspect cases) as well as 57 deaths were reported from Guinea, Liberia, Nigeria, and Sierra Leone. The Ebola epidemic trend in Guinea, Liberia, and Sierra Leone remains precarious with ongoing community and health-facility transmissions of infection. The surge in the number of new EVD cases calls for concentrated efforts by all to address the identified problems, such as health facility transmission and effective contact tracing.

Health sector response

In an effort to accelerate the response to the current EVD outbreak in West Africa, the Director General of WHO and other senior managers continue to hold discussions with the donor community, development partners, and international agencies at a global level. Focus of the discussion has centered on the need to rapidly deploy additional human and financial resources that will help interrupt Ebola transmission and end the outbreak.

Efforts are currently ongoing to scale up and strengthen all aspects of the response in the four countries, including epidemiologic investigations, contact tracing, public information and community mobilization, case management and infection prevention and control, coordination, and staff security. WHO is also working closely with various partners to finalize the national response plans that define urgent response needs in line with the Accra strategy adopted by Member States.

WHO does not recommend any travel or trade restrictions is applied to Guinea, Liberia, Nigeria, or Sierra Leone based on the current information available for this event.>
