Health care and welfare resources generally are believed to be poor, although reliable information about conditions is often difficult to obtain. In 2001, the most recent year for which figures are available, the Eritrean government spent 5.7 percent of gross domestic product on national health accounts. The World Bank's World DataBank estimated that in 2004 there were only 50 physicians per 100,000 people in Eritrea, while the World Health Organization (WHO) estimated only 3. The two-year war with Ethiopia, coming on the heels of a 30-year struggle for independence, negatively affected the health sector and the general welfare. The rate of prevalence of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), although low by sub-Saharan African standards, was high enough at 2.7 percent in 2003 to be considered a generalized epidemic.
