Nearly 1,800 people under the age of 15 are infected with HIV around the world every day. Now, in an extension of its Unite for Children, Unite Against AIDS campaign, UNICEF is partnering with Family Health International to tackle mother-to-child transmission and improve pediatric care. The groups will work in Guyana, India, Malawi, Nigeria and Zambia to address such challenges as the shortage of medical workers and rural women’s limited access to clinics. The initiative will push UNICEF toward its goal of providing services to 80 percent of HIV-positive women and children in need by 2010. It should also help the U.N. Millennium Development quest to halt and reverse the spread of  HIV/AIDS by 2015. Jimmy Kolker, UNICEF chief of HIV/AIDS, says the partnership is “a good example of how if we’re actually going to make an impact, UNICEF alone has no hope of doing that.” Ready, team?
