On 27 October, WHO supported Borno State Ministry of Health to train 37 health workers as part of its scale up plan for the Hard to Reach Teams (HTR) programme in Borno State. Those trained were selected from six newly liberated Local Government Areas including Dikwa, Gwoza, Kukawa, Mafa, Munguno and Ngala.

From 16 to 22 October, WHO through the HTR programme supported Borno State Ministry of Health (SMOH) to vaccinate 9,870 children less than five years against polio using Oral Polio Vaccine (OPV) and 754 using Inactivated Polio Virus. A total of 965 children were also vaccinated against measles.
