Millions of pleasantly plump Americans were stepping a little lighter. A study from the Centers for Disease Control and Prevention (CDC) had just concluded that folks who are overweight but not obese are at no greater risk of dying prematurely than people of normal weight. You could almost hear the national sigh of relief in the newspaper articles, radio talk shows and monologues of late-night comedians that followed. "I can't tell you how happy this makes me," David Brooks wrote in the New York Times, which devoted a front-page story, an editorial and two Op-Ed pieces...
Kelli's tale is no longer unusual.

According to the CDC, antiretroviral-drug therapy can lead to premature birth or mitochondrial misfunction, a lethal defect, but such problems are extremely rare...

Curran thinks it may prove significant that "about 15% of the men whose cases remain...
...keep tainted blood away from the donor centers, the CDC is setting up alternative sites where people at high risk for AIDS can take the test with assurance that the results will remain confidential. Whether tests are administered there or at donor centers, one dilemma remains: how to relate the frightening news to someone whose blood has tested positive, and to interpret that finding...
