The survivors risk life-long neurological deficit and other serious problems. Accurate diagnosis and injectable treatment are urgently needed to deal with the condition. Yet, children with signs of severe malaria often reside in remote locations. Professor Karim Hirji of Muhimbili University in Tanzania describes the significance of his own research.
