A WHO mission investigated the situation in Kenema District from 14 to 21 February to redirect control activities, review existing surveillance activities identify future needs and prepare a plan of action. The cooperation of NGOs based in the area such as MERLIN, UK, have resulted in improved communications for a rapid patient referral.
