BRUSSELS — Thousands more physicians, especially epidemiologists, and other health professionals are needed to halt and eradicate Ebola, European Union officials said Tuesday after returning from countries in West Africa hit by the deadly epidemic.

EU Health Commissioner Vytenis Andriukaitis said the requirements include paramedics, nurses and health care volunteers.

“We need these people to provide treatment and also to locate Ebola victims, guide them toward clinics, train local personnel, perform contact tracing, implement awareness programs,” Andriukaitis said.

He said other pressing needs include mobile laboratories, leaflets showing people how to stem the spread of the virus and thousands of portable toilets to improve sanitation and the purity of the water supply.

The trade bloc’s Ebola coordinator, Christos Stylianides, said greater help is required “today, not tomorrow – it’s very crucial.”

The EU officials spoke to journalists after returning to Brussels from the countries most affected by Ebola: Liberia, Sierra Leone and Guinea.

Stylianides said the trip left him shaken and his immediate priority will be drafting an EU “action program.” The program will specify exactly how many doctors, nurses, hygienists and other professionals are needed in West Africa, what specialties they should possess, and what training they will require.

After meeting with officials in the affected countries, Stylianides said he felt more reassured that people leaving there for Europe or other destinations will be checked for Ebola symptoms.
