Health officials say the rate of people infected with gonorrhea in Cincinnati is declining. For the first time in five years, the city is not expected to have the state's highest rate of infection for the sexually transmitted disease. The city's chlamydia infection rate is also dropping, but it's expected to remain the worst in Ohio. The STDs are the two most common in Ohio and the nation. State health department officials say the drops in Cincinnati infection rates are tough to explain. They say more people could be using condoms or practicing abstinence. Or, more people could just be avoiding getting tested. Health officials say they'll have a better idea of the trend at the end of the year. Their projections are based on cases reported through March 31st.
