Frequently asked questions about sexual health & STIs
What is a sexually transmitted infection (STI)?
Sexually transmitted infections (STIs) are diseases caused by viruses, bacteria, fungi or parasites that are transmitted mainly through vaginal, anal or oral sexual contact. Many can be prevented, diagnosed early and treated effectively.
What is the human papillomavirus (HPV)?
HPV is the most common sexually transmitted infection in the world. There are more than 200 types of the virus; some cause genital warts and others can increase the risk of developing certain cancers, such as cancer of the cervix, penis, anus, vulva, vagina and oropharynx.
How is HPV transmitted?
HPV is transmitted mainly by direct skin-to-skin contact during sexual activity, even without penetration. It can also be transmitted through oral sex and genital contact.
Is HPV common?
Yes. It is estimated that most sexually active people will contract HPV at some point in their lives. In most cases, the infection clears spontaneously thanks to the immune system.
Does HPV always cause symptoms?
No. Most infected people have no symptoms and are unaware that they carry the virus. This is why medical follow-up and screening programmes, when indicated, are important.
What are condylomas or genital warts?
They are benign lesions caused by certain types of HPV, generally types 6 and 11. They can appear on the genitals, anal or perineal area and are usually treated with medical treatments or in-office procedures.
