According to a press release, Rostropovich will advocate for "HIV prevention, treatment, care, and support for children and youth," making use of his "network in politics, humanitarian affairs, and culture." He will also assist UNAIDS in its efforts to integrate institutionalized children into society.
"HIV poses a serious health risk to everyone—particularly to children", Rostropovich said in a statement. "Every day children die, because they do not have access to prevention, treatment, care, and support that could have saved their lives. This is not only a health issue, it is an issue of fundamental equity and human rights."
In 1991, Rostropovich and his wife, soprano Galina Vishnevskaya, created the Vishnevskaya-Rostropovich Foundation, a non-profit organization dedicated to children's health in the former Soviet Union.
