The World Health Organization (WHO) on Monday appealed for greater attention to AIDS patients' nutrition problems, an issue particularly deteriorated by food shortage in sub-Saharan Africa. Health specialists and social workers from 20 eastern and southern African countries opened a three-day WHO meeting in Durban on Monday, with aims to develop feasible strategies to help improve the health status of people living with HIV/AIDS. Nutrition is one of the critical aspects of the care and support for people living with HIV/AIDS, which, however, has been largely ignored, said WHO's Director General Lee Jong-wook.
