Ebola Crisis: Mali places almost 600 under Ebola surveillance Fearful of a surge of Ebola cases, Mali has placed nearly 600 people under surveillance, as the country battles to contain the spread of the deadly virus. Malian officials met to consider increasing security at the border following two confirmed cases of Ebola due to infection in neighbouring Guinea. US airports also announced plans to begin enhanced screening of travellers from Mali. Mali has been struggling to prevent a minor outbreak from turning into a major crisis after the deaths of a Guinean imam and the Malian nurse who treated him, in the capital Bamako. News 24
