ADDIS ABABA: Ten African countries are at risk of being affected by the Ebola virus, in addition to the Democratic Republic of Congo and Uganda, the African Union’s health agency warned on Saturday.

“We have 10 countries at risk,” said Jean Kaseya, head of the Africa Centers for Disease Control and Prevention, listing Angola, Burundi, the Central African Republic, the Republic of Congo, Ethiopia, Kenya, Rwanda, South Sudan, Tanzania, and Zambia.

The World Health Organization has declared the outbreak of the highly contagious hemorrhagic fever an international emergency.

Uganda confirmed three new Ebola cases on Saturday and the Red Cross said three volunteers died in the neighboring Democratic Republic of Congo, amid warnings the deadly virus could spread to several more African countries.

Kaseya said “high mobility and insecurity” in the region were helping spread the disease.
