Chlamydia is most common among young people. Two-thirds of new chlamydial infections occur among youth aged 15-24 years. Estimates show that 1 in 20 sexually active young women aged 14-24 years has chlamydia. Disparities persist among racial and ethnic minority groups.
In nine of the twenty-five studies there was a statistically significant sex difference in the chlamydia prevalence. In all nine studies the prevalence of chlamydia was higher in women than in men. The prevalence for women varied from 1.1% to 10.6% and for men from 0.1% to 12.1%.
A woman's anatomy is more exposed and vulnerable to STDs than male anatomy, as her vagina is thinner and more delicate, making it easier for bacteria and viruses to penetrate.
Because the vagina is moist and has a thin lining, it's easier for a woman to get an STI than it is for a man to get one. Also, a woman is less likely to have symptoms of common STIs — such as chlamydia and gonorrhea — compared with a man.
Sexually active young people are at a higher risk of getting chlamydia. This is due to behaviors and biological factors common among young people. Gay and bisexual men are also at risk since chlamydia can spread through oral and anal sex.
Queensland has more cases of the sexually transmitted infection (STI) than any other state, with 15,197 reported chlamydia infections last year, followed by New South Wales and Victoria with 14,023 and 12,225 respectively. Chlamydia cases have risen almost four-fold in Queensland in the past 10 years.
Between 2016 and 2017, notification rates increased by 9% in New South Wales and by 8% in South Australia and Victoria. Notification rates of chlamydia have been highest and remained stable in remote and very remote regions in the 5-year period from 2013 to 2017 (824.6 per 100,000 in 2017) (Kirby Institute 2018a).
Chlamydia is the most common sexually transmitted infection (STI) in Australia, particularly among young people aged between 15 and 25 years. You can reduce your risk of getting chlamydia by practising safe sex, and limiting your sexual partners.
According to the CDC , chlamydia is typically transmitted through sexual contact, but it can occur whenever the bacteria enters another person's body. Transmission usually takes place during penetrative sex, whether vaginal or anal. However, it can also spread through oral sex or the sharing of sex toys.
Previous data suggest that females are more likely to contract Chlamydia trachomatis from infected males than males are likely to contract it from females.
Myth: You can't catch chlamydia if you've only had sex once. Fact: If you have sex once with a partner who's got chlamydia, you've got around a 30% chance that you'll pick up the infection from that one time.
One in six Australians has had a notable STI in their lifetime, and knowing what the risks are – and how to prevent them – is crucial for maintaining good sexual health.
More testing means more diagnosis
Experts agree that for chlamydia, most of the increase can be attributed to diagnostic testing. Advances in technology have created more accurate tests, which have helped to identify more infection. The number of tests conducted has increased over time as well.
About 16 per cent of Australians report having an STI at some point in their lifetime — that's roughly 4 million people. With the exceptions of hepatitis and HIV, Australia's most common STIs are on the rise.
Retesting 3 months after diagnosis of chlamydia, gonorrhea, or trichomoniasis can detect repeat infection and potentially can be used to enhance population-based prevention (136,137).
About half of these infections are in people between the ages of 15 and 24. Young people are at greater risk of getting an STD for several reasons: Young women's bodies are biologically more prone to STDs. Some young people do not get the recommended STD tests.
Chlamydia is a SUPER common bacterial infection that you can get from sexual contact with another person. Close to 3 million Americans get it every year, most commonly among 14-24-year-olds. Chlamydia is spread through vaginal, anal, and oral sex. The infection is carried in semen (cum), pre-cum, and vaginal fluids.
Using condoms for oral, anal or vaginal sex. Condoms, when used consistently and correctly, can reduce the risk of transmission of gonorrhea and chlamydia. Use a condom or latex barrier for oral sex on a vagina or anus.
The initial damage that chlamydia causes is often unnoticed. However, infections can lead to serious health problems with both short- and long-term effects. If a woman does not receive treatment, chlamydia can spread into the uterus or fallopian tubes, causing PID.
As most people do not have symptoms, it is possible the person (who tested positive) could have had chlamydia/gonorrhea from a previous relationship, and has not passed it to their partner yet. It is never 100% that you will pass an STI when you have sex.
