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.
The national birth rate fell 4 percent between 2007 and 2009 — more than it had in any two-year period in the past 30 years. With a national average of 66.7 births per 1,000 women between the ages of 15 and 44, nearly every demographic group had lower birth rates, with the sole exception being women over 40.
By age, the largest decline was 9 percent, among women between 20 and 24. Fertility rates among Hispanic women also dropped by 9 percent.
