Mali has been scrambling 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.
"The number of contacts followed by health services amounts to 442. They have all been placed under observation for health control," Samba Sow, of the Ebola emergency operations center, said in a statement late Sunday.
Teams of investigators have been tracking health workers and scouring Bamako and the imam's village of Kouremale, which straddles the Mali-Guinea border, for people who could have been exposed.
