Health authorities have introduced a new treatment for trypanosomiasis, also known as sleeping sickness, in the eastern province of Haut Mbomou in the Central African Republic (CAR), an official told IRIN on Saturday. Dr Carlos Recio, the coordinator of Medecins Sans Frontieres (MSF) in the CAR, said the new drug had been introduced after a significant percentage of patients developed resistance to Melarsoprol, the drug that had previously been used.
