When: December 2, 2007
Where: United States of America
Who: U.S. citizens
What: More people in the United States are infected each year with the AIDS virus than previously thought in a finding that could affect the debate over how much money should be spent on prevention efforts.
Why: For 14 years, the Center for Disease and Prevention used informal methods to estimate that about 40,000 people annually in the United States are newly infected with H.I.V. In recent years, federal officials have worked to set up a more accurate assessment technique.
