MEDFORD, Ore. -- Sexually transmitted diseases are on the rise across the United States, according to the latest numbers from the U.S. Centers for Disease Control.
There were more than 2 million new cases of gonorrhea, syphilis and chlamydia across the U.S. in 2016 -- the highest number of new cases yet.
The latest "Sexually Transmitted Disease Surveillance Report" report from the CDC says there were more than 1.6 million cases of chlamydia, 470,000 new cases of gonorrhea, and nearly 28,000 new cases of primary and secondary syphilis.
CDC officials say funding cutbacks for prevention, education, and healthcare programs are a big part of the reason STDs are on rise.
Chlamydia is the most common STD. It's often called the "silent" infection, because many carriers don't have symptoms, which means it often goes untreated. However, it can lead to pelvic inflammatory disease, which can leave scars and affect fertility.
Gonorrhea often includes symptoms like discharge, or burning during urination, and can lead to severe and permanent health problems.
Syphilis is the most serious STDs caused by bacteria. Symptoms can mimic other diseases, but if it's left untreated, it can affect the brain, heart and other organs. It can also be deadly.
