An STI is a sexually transmitted infection. Sexually transmitted means that the infection is passed on during sex or when infected areas of the body, usually the genitals, come into contact with someone else. Sometimes STIs are also called STDs, in which case the D refers to disease.
Most common STIs: gonorrhoea, chlamydia, genital herpes, genital warts, syphilis
Effects from STIs: warts, rashes, itch, infertility, discharges and more
Chlamydia is a very common STI. It does not cause any symptoms in most people but its effects can be devastating. When left untreated, chlamydia causes infertility in women.
A herpes infection which causes painful blisters and sores on the genitalia, anus or thighs. Once you have had an outbreak, the virus will come back, this might occur in weeks but could also take years. Herpes can not be cured but its symptoms can be controlled and eased.
Genital warts is an STI which causes small wart-like, bumpy growths around the genitals or anus. This STI is usually easily noticable and might cause embarrassment or stress. As it is passed on by skin-on-skin contact, it is very contagious, it is however also very treatable.
Women are usually unaware they have gonorrhoea but might experience pain or discomfort around the vagina or with urinating. Men may have white, yellow or green discharge from the penis when infected with gonorrhoea. Gonorrhoea is an STI which can be successfully treated but can have serious consequences when left untreated, such as infertility.
Trichomonas vaginalis is an STI caused by a parasite. In women it might cause a white or yellow smelly discharge, and pain or discomfort around the vagina. Men usually don’t experience symptoms.
