Following two successful rounds of integrated biological and behavioural surveillance (IBBS) surveys in 2008 and 2014 in Somaliland, the International Organization for Migration (IOM) undertook a third survey in 2017. In collaboration with the AIDS Commission, Ministries of Health and UNICEF, IOM undertook the survey with sex workers and clients, including uniformed personnel, port workers and truckers across three cities in Somalia – Hargeisa, Bossaso and Mogadishu.
