Among New Yorkers, the herpes rate is higher among women, black people and gay men

A city Health Department study finds that more than a fourth of adult New Yorkers are infected with the virus that causes genital herpes. The study, released Monday, says about 26% of New York City adults have genital herpes, compared to about 19% nationwide. The department says genital herpes can double a person's risk for contracting HIV/AIDS.
