You can't tell if someone has an STI just by looking at them. Many infections don't cause any symptoms, so the only way to know for sure is to get tested. Even if you use birth control, you should still think about STI prevention.
Symptoms can occur within 2-14 days after infection. However, a person may have chlamydia for months, or even years, without knowing it.
Symptoms in women
an unusual vaginal discharge, which may be thin or watery and green or yellow in colour. pain or a burning sensation when passing urine. pain or tenderness in the lower abdominal area – this is less common. bleeding between periods, heavier periods and bleeding after sex – this is less common.
Symptoms usually appear after 1 to 3 weeks but can start much later. Symptoms include: discharge from the vagina or penis. pain when peeing.
Many STIs have no signs or symptoms (asymptomatic). Even with no symptoms, however, you can pass the infection to your sex partners. So it's important to use protection, such as a condom, during sex.
People with STDs/STIs may feel ill and notice some of the following signs and symptoms: Unusual discharge from the penis or vagina. Sores or warts on the genital area. Painful or frequent urination.
Yeast infections that occur in the same places as STDs—the mouth, vagina, and penis—are the infections most often confused with STIs.
HPV is the most common STI in the United States, but most people with the infection have no symptoms.
Chlamydia bacteria often cause symptoms that are similar to cervicitis or a urinary tract infection (UTI). You may notice: White, yellow or gray discharge from your vagina that may be smelly. Pus in your urine (pyuria).
STD stands for “sexually transmitted disease,” and STI stands for “sexually transmitted infection.” But no matter which term people use, they're talking about the same thing: infections that get passed from one person to another during sex.
Repeat testing may be needed in some cases. All sexually active gay, bisexual, and other men who have sex with men should be tested: At least once a year for syphilis, chlamydia, and gonorrhea. Those who have multiple or anonymous partners should be tested more frequently (e.g., every 3 to 6 months).
Treatment of STIs
Effective treatment is currently available for several STIs. Three bacterial (chlamydia, gonorrhoea and syphilis) and one parasitic STIs (trichomoniasis) are generally curable with existing single-dose regimens of antibiotics.
Cloudy urine. Abnormal vaginal discharge. Abnormal vaginal bleeding with intercourse or between periods.
Although chlamydia is highly contagious, it does not always transmit to a person's sexual partners. It is also possible to have a false-negative test result. Having more frequent sex with a partner who has chlamydia may increase a person's risk of contracting it.
Other symptoms can include fever, swollen lymph glands, sore throat, wart like lesions, condyloma lata, may develop in warm moist areas, patchy hair loss, headaches, weight loss, muscle aches, and fatigue or feeling very tired. The symptoms will go away with or without treatment.
Signs and Symptoms of Syphilis in Females. The characteristic sign of syphilis is the appearance of a sore, known as a chancre, on the infected area. These sores are firm, round, and painless, though they can potentially burst and become open and wet. This is also when the bacterial infection is at its most contagious.
The characteristic rash of secondary syphilis may appear as rough, red, or reddish brown spots both on the palms of the hands and the bottoms of the feet. However, rashes with a different appearance may occur on other parts of the body, sometimes resembling rashes caused by other diseases.
