(CNN) There were more reported cases of sexually transmitted diseases last year than ever before in the United States, according to the latest STD surveillance report by the Centers for Disease Control and Prevention. The annual report, which was released on Wednesday, showed that the rates of chlamydia, gonorrhea, and syphilis -- the three most commonly reported STDs in the nation -- increased between 2014 and 2015, reaching an all-time high. Reported cases of primary and secondary syphilis rose by 19%, gonorrhea cases rose by 12.8%, and chlamydia cases rose by 5.9%, from 2014. All three STDs are curable with antibiotics, but most infections go undiagnosed and untreated, according to the CDC.Chlamydia, gonorrhea and syphilis rates hit an all-time high last year, new report shows"We have reached a decisive moment for the nation," CDC official says
Scientists at the _ warned in July that the bacterium that causes gonorrhea, called Neisseria gonorrhoeae, is developing resistance to the antibiotic drugs used to treat it. It's estimated that about half of the nearly 20 million new _ cases reported annually are among 15 to 24 year olds. In a foreword to the new report, Bolan wrote that some 21 health department _ clinics across the country have closed due to many state and local programs experiencing budget cuts. To address the recent _ upsurge, Bolan recommended that surveillance systems that collect data on new STD cases should be improved and people with new diagnoses should be provided access to treatment.
