Aids Worse than Thought; Prevention Paying Off
Updated federal estimates of the annual number of new HIV infections in the United States, released yesterday, reveal that although the AIDS epidemic here is worse than previously thought, prevention efforts appear to be having some effect.Even though the number of Americans living with HIV has risen by more than a quarter-million people since 1998 -- largely because of life-extending antiretroviral drugs -- the number of new cases each year has declined slightly over that period. That suggests that a person's likelihood of transmitting the virus to someone else is substantially lower now than it was a decade ago. In December, The Washington Post reported that the CDC was revising HIV incidence upward to 50,000 to 60,000 cases a year. Yesterday's announcement -- and the publication of a paper in the Journal of the American Medical Association -- is the first official acknowledgment of the new, higher estimate.
