US authorities on Monday were to begin enhanced Ebola screenings of travelers from Mali upon arrival in the United States amid fears of a surge in cases in the African country.
  
The special measures are already in place in for travelers arriving from three other West African nations -- Liberia, Sierra Leone, and Guinea.
  
The US Centers of Disease Control and Prevention, in a joint statement with the Department of Homeland Security, said Mali was being added to the list "because there have been a number of confirmed cases of Ebola" there in recent days.
  
"A large number of individuals may have been exposed to those cases," the statement said. "The action is warranted as a precaution due to the possibility that other cases of Ebola may emerge in Mali in the coming days," the statement said, adding that CDC will continue to reassess the measure.
 
The United States said there are about 15-20 travelers who depart Mali each day en route to the United States. Officials said travelers entering the United States from Mali also will be subject to the 21-day monitoring and movement protocols already in effect for travelers from Liberia, Sierra Leone and Guinea, with mandatory twice daily temperature and symptom checks in coordination with state and local public health authorities.
