STDs proliferate 45 percent over five years in California
Reported sexually transmitted diseases reach a new high in California according to 2017 statistics
SACRAMENTO – The need to be careful when engaging in sex with a partner is the highest it has ever been according to the latest numbers released by the California Department of Public Health (CDPH). According to the CDPH the number of Californians diagnosed with a sexually transmitted disease (STD) in 2017 hit a record high.
More than 300,000 cases of chlamydia, gonorrhea, and early syphilis were reported: a 45 percent increase compared to five years ago. In chlamydia cases in California alone, the rate was 552.1 cases per 100,000 Californians amounting to a 9% increase over 2016’s numbers. As well, 218,710 chlamydia cases reported in 2017 was the highest number since reporting began in 1990 and 54% of cases were among people under the age of 25.

In 2017, for gonorrhea cases alone there were 190.5 cases per 100,000 Californians, amounting to a 16% increase over 2016. The 75,450 gonorrhea cases reported in 2017 was the highest number since 1988. And cases of gonorrhea rates among males were two-fold higher than among females, while Chlamydia rates among females were 60% higher than among males. A third of all gonorrhea cases in California were among people under the age of 25.
Syphilis in 2017 had a startling increase in cases compared to 2016. Last year the rate of early syphilis cases was 34.3 cases per 100,000 Californians, amounting to an increase of 20% over 2016. The 13,605 early syphilis cases reported in 2017 (6,633 primary/secondary and 6,972 early latent) was the highest number since 1987. Since 2012, females cases increased nearly seven-fold from 250 cases of early syphilis reported. Also interesting is African-American early syphilis rates were over two times higher than their white Californian counterparts.
Particularly concerning, in 2017, there were 30 stillbirths due to congenital syphilis in California. This is the highest number reported since 1995.
The CDPH notes STDs can cause a number of serious health problems. If left untreated, chlamydia and gonorrhea can cause pelvic inflammatory disease and lead to infertility, ectopic pregnancy, and chronic pelvic pain. Syphilis can cause permanent loss of vision, hearing and other neurologic problems.
Chlamydia and gonorrhea rates are highest among people under age 30. Rates of chlamydia are highest among young women, and males account for the majority of syphilis and gonorrhea cases.
“STDs are preventable by consistently using condoms, and many STDs can be cured with antibiotics,” said CDPH Director and State Public Health Officer Dr. Karen Smith. “Regular testing and treatment are very important for people who are sexually active, even for people who have no symptoms. Most people infected with an STD do not know it.”
CDPH is collaborating with local health departments and organizations throughout the state
to raise awareness. CDPH is working with the California Department of Education and community groups to implement the newly enacted California Healthy Youth Act, which mandates comprehensive STD/HIV prevention education in schools.
