STD symptoms, and why many infections have none.

Many sexually transmitted infections cause no symptoms, especially early on. Symptoms can be a clue, but testing is the only way to know.

Symptoms to look out for

  • Pain or burning when passing urine
  • Unusual discharge from the penis, vagina or rectum
  • Sores, blisters, lumps or ulcers on the genitals, anus or mouth
  • Itching or irritation around the genitals
  • Bleeding between periods or after sex
  • Pain in the testicles or lower abdomen
  • A rash, often on the palms or soles, or flu-like symptoms weeks after sex

Why no symptoms does not mean no infection

Chlamydia, gonorrhoea, syphilis, HIV and hepatitis can all be present for months with no symptoms, and can still be passed on. If you have had a new partner, a condom failure or any concern, testing is the reliable answer.

Early HIV symptoms

Some people have a flu-like illness with fever, sore throat, rash or swollen glands two to four weeks after HIV infection. Many have none. If you had a possible exposure in the last 72 hours, do not wait for symptoms: call about PEP now.
