The Influence of AIDS

The rise of acquired immune deficiency syndrome (AIDS) around the earth has represented a major challenge to medical progress both in developed and in less - developed countries. The past forty years saw great success in the control of spreading diseases and great strides toward achieving "health for all by the year 2000" (a major WHO goal) through improved basic health care, food, cleanliness, and immunization(免疫) programs.

Yet, because of its sudden start and rapid spread, AIDS could soon wipe out this progress. By the end of 1988, more than 130,000 cases of AIDS were reported, but, because of under reporting, there may actually be more than 350,000 cases. Also, at least five million persons likely have the human immunodeficiency virus (HIV) (艾滋病病毒), which causes AIDS. That means as many as 400,000 new cases of AIDS could occur in the next few years - more than doubling the present total. Caring for AIDS patients could seriously stress economic resources even in richer countries.

Preventing one case of AIDS means preventing many future cases, while preventing a case of measles(麻疹) or malaria(疟疾) in Africa would have little effect on its spreading, since those diseases are already common in many countries. Resources devoted to AIDS testing, care, and education could also be used to battle other, more-known diseases in developing countries.
