Abuja, 08 July, 2014 - The Stop Transmission of Polio (STOP) program started in 1998 with the primary aim to strengthen acute flaccid paralysis (AFP) surveillance, support national immunization days, and conduct polio case investigation and follow-up. These activities remain today but the program has grown to include strengthening routine immunization, measles mortality reduction, supportive supervision, and strengthening the Integrated Disease Surveillance program.
