Latest figures on Integrated Management of Childhood Health (IMCI) implementation in Yemen for 2009 confirm significant results of the Ministry of Public Health and Population initiatives in reaching out to children. By the end of 2009, 57% of health facilities in the country had staff trained in IMCI to provide primary child health care services, with an estimated 1 291 129 under-five children living in areas served by those facilities. A further step forward was reaching out to an additional under-five population estimated at 1 528 913 in more remote areas through primary health care (PHC) mobile teams, including staff trained in IMCI. The mobile teams were established on a trial basis in 2007. These services, also supported by the GAVI-health system strengthening initiative, WHO, UNICEF and other partners, are currently serving 76 districts through 537 mobile teams. The estimated total under-five population living in areas where IMCI health services are available is thus about two thirds (65.5%) of the total under-five population in the country. These efforts are likely to contribute to accelerating progress towards Millennium Development Goal #4 to reduce under-five deaths in the country by two-thirds between 1990 and 2015.
