Paragraph: More than 336,000 cases of chlamydia, gonorrhea and syphilis were reported last year, as rates of all three STDs continued to increase across the state, the California Department of Public Health reported. Officials said they are particularly concerned by the number of congenital syphilis cases, which were 14% higher than the previous year and nearly 900% higher than in 2012. There were 22 stillbirths or neonatal deaths because of syphilis last year, the report said. If left untreated, syphilis can result in blindness, hearing loss and neurological problems. Chlamydia and gonorrhea can lead to infertility, ectopic pregnancy and chronic pelvic pain. Many STDs can be cured with antibiotics. The highest rates of STDs are among young people ages 15 to 24, officials said. The department's acting director, Dr. Charity Dean, urged sexually active people to use condoms and get tested. "Regular testing and treatment are essential prevention strategies, even for people who have no symptoms," Dean said in a statement. "Most people infected with an STD do not know it." State officials are collaborating with local agencies to coordinate efforts to control STDs, the health department said. Claim: Report finds cases of STDs reach 30-year high in California.
The number of cases of three major sexually transmitted diseases in California reached a 30-year high in 2018, according to a state report released Tuesday.
