STI Symptoms: Getting Aware About Sexual Transmitted Infections in the UK

Sexually transmitted infections (STIs) are generally caused by bacteria, parasites, or viruses when a person gets in sexual contact with an infected person. Bacteria or viruses that cause STIs can typically get transmitted by engaging in unprotected sexual intercourse, including vaginal, oral, and anal sex.

There are several common sexually transmitted infections you might have heard of, such as Chlamydia, Gonorrhea, Genital Herpes, Genital Warts, Pubic Lice, and Scabies, among others. 

Many STIs, like Chlamydia and Gonorrhea, do not often show symptoms, which means you can unknowingly infect your sexual partner during sex if you have an STI.

That’s why it is crucial for you to be aware of the common STIs and their symptoms. We are going to list down some of the most common sexually transmitted infections (STIs) along with their symptoms to promote not only the awareness of STI symptoms but also the essential knowledge for early detection and treatment of such STIs. 

Let us explore various popular STIs in the UK and their associated symptoms. 

Scabies Symptoms

Human scabies is a parasitic infestation caused by Sarcoptes scabiei var hominis, which are tiny mites that can burrow into the skin to let the individual experience intense itching and rashes. In this condition, you can notice pimple-like rashes anywhere on your body. The symptoms of scabies usually appear after 4 to 6 weeks of parasitic infestation. Here are some common symptoms of scabies you may experience:

  • Severe itching

  • Rashes in infants and children on the palm, soles of the feet, and scalp. 

  • Itchy lines or rashes on the fingers, wrists, arms, legs, and hands.

  • Bumps or Papules on male genitalia and female breasts

Medications for the treatment of Scabies:

  • Permethrin Cream is a widely prescribed topical treatment for scabies, effectively combating the infestation caused by mites by disrupting their nervous system.
  • Eurax Cream is also utilized for scabies treatment, providing relief by alleviating itching and eradicating mites through its active ingredient, crotamiton.

Chlamydia Symptoms
