Officials at the Centers for Disease Control are calling for cheaper and wider access to birth control because of the outbreak of the Zika virus.

“Because contraception is the primary means to prevent unintended pregnancy for women at risk for Zika virus infection, sexually active nonpregnant women of reproductive age and their sex partners need to have access to all approved contraceptive methods, and these methods need to be readily available and accessible,” the CDC said in a report released Tuesday.
