STDs continue to spread

U.S. researchers reported this week that the reluctance to talk about sex and protection has led to an increase in STD infections, especially among vulnerable teens.

Chlamydia, gonorrhea and syphilis infections continue to spread in the United States, according to the latest statistics.

John Douglas, director of the division of sexually transmitted diseases at the U.S. Centers for Disease Control and Prevention, said the U.S. has among the highest rates of STDs of any developed country in the world.
