Everyone knows that when your kids get the flu, they stay home from school.
But what does it take to justify closing the school down entirely? That's a question we should probably answer before the next big pandemic hits.
At one point during the swine flu outbreak in 2009, the Centers for Disease Control and Prevention said, "The potential benefits of preemptively dismissing students from school are often outweighed by negative consequences," such as disruption of classes and hassles for parents.
This week's meeting of the International AIDS Society Conference comes with a CDC study showing a major advance in sexual health. Correspondingly, Botswana trials showed the drug Truvada prevented HIV transmissions in more than 60 percent of heterosexuals. The study's author Dr. Michael Thigpen and host Michel Martin discuss how much Truvada costs, why HIV is so pervasive among women in Botswana, and how much people must take the drug for it to be effective.
