Gonorrhea is one of the most common sexually transmitted infections in the world. The World Health Organization estimated 82.4 million new infections among adults aged 15 to 49 globally in 2020 alone. In the United States, provisional CDC data for 2024 counted 543,409 reported cases, a rate of about 160 per 100,000 people. And because a large share of infections produce no symptoms, the true number is almost certainly higher.
U.S. Cases: Recent Trends
After nearly a decade of climbing numbers, gonorrhea rates in the U.S. have started to decline. The national rate dropped from 214 per 100,000 in 2021 to about 180 per 100,000 in 2023, with the sharpest decreases among young adults. The 2024 provisional figure of roughly 160 per 100,000 suggests that downward trend is continuing, though researchers are still investigating what’s driving it. Possible factors include changes in testing patterns, shifts in sexual behavior, and expanded access to prevention resources.
To put the numbers in perspective, gonorrhea is the second most commonly reported notifiable infection in the country, behind chlamydia. Even with the recent decline, current rates remain substantially higher than they were a decade ago.
Who Gets Gonorrhea Most Often
Young adults carry a disproportionate share of infections. Rates are highest among people in their late teens through their twenties, and this age group has also seen some of the steepest recent declines.
Gay, bisexual, and other men who have sex with men (MSM) are affected at especially high rates. A CDC surveillance study across five U.S. cities found that about 13% of MSM tested positive for chlamydia, gonorrhea, or both at one or more body sites. Rectal gonorrhea was detected in roughly 4.5% of participants, and pharyngeal (throat) gonorrhea in about 4.6%. Among MSM living with HIV, rectal gonorrhea prevalence was more than double the rate seen in HIV-negative men (8.2% versus 3.3%). A broader systematic review of studies from 2000 to 2016 placed rectal gonorrhea prevalence among MSM at around 6%.
Racial and ethnic disparities are also significant. Black and Hispanic MSM had higher rates of pharyngeal gonorrhea compared to white MSM in the same surveillance data, reflecting longstanding inequities in STI burden that are shaped by access to healthcare, screening availability, and social determinants of health rather than biology.
Most Infections Cause No Symptoms
One reason gonorrhea spreads so easily is that the majority of infected people don’t know they have it. Approximately 90% of women with urogenital gonorrhea have no symptoms at all. Among men, asymptomatic rates are also high, ranging from about 56% to 87% depending on the study. Infections in the throat and rectum are particularly likely to be silent, which is why routine screening rather than symptom-based testing is so important for people at higher risk.
This silent spread also explains why reported case counts underestimate the true burden. Many infections are never diagnosed, never treated, and never counted in surveillance data.
Reinfection Is Common
Getting treated for gonorrhea doesn’t protect you from catching it again. Research from the California Department of Public Health found that as many as 20% of women tested positive for chlamydia or gonorrhea again within just six months of their initial diagnosis and treatment. This is why the CDC recommends retesting about three months after treatment, regardless of whether your sexual partners were also treated. Reinfection carries the same risks as a first infection, including complications that can affect fertility.
What Happens If It Goes Untreated
Untreated gonorrhea can lead to pelvic inflammatory disease (PID) in women, an infection of the uterus, fallopian tubes, or ovaries. When gonorrhea and chlamydia are present together, which is common, as many as 30% of women develop PID. Once PID occurs, 15% to 20% of those women go on to experience infertility. PID can also cause chronic pelvic pain and increase the risk of ectopic pregnancy.
In men, untreated gonorrhea can cause a painful infection of the tubes near the testicles, which in rare cases also leads to fertility problems. In anyone, the infection can occasionally spread to the bloodstream and joints, causing a serious condition that requires hospitalization.
Antibiotic Resistance Is Growing
One of the biggest public health concerns around gonorrhea isn’t just how common it is, but how hard it’s becoming to treat. Between 2022 and 2024, resistance to the two primary antibiotics used against gonorrhea rose sharply. Resistance to the injectable antibiotic most commonly used as first-line treatment jumped from 0.8% to 5% of tested samples worldwide, according to WHO surveillance data published in late 2025. Resistance to the oral alternative climbed from 1.7% to 11%. An older class of antibiotics (fluoroquinolones) is now essentially useless, with 95% resistance.
For now, first-line treatment still works in the vast majority of cases. But the trend is accelerating, and resistant strains are being detected in more countries every year. This makes prevention, screening, and prompt treatment more important than ever, because every untreated or inadequately treated infection gives the bacteria another chance to evolve.
