Sexually active adolescents face serious health risks associated with unprotected sexual intercourse including HPV and other sexually transmited diseases as well as unwanted pregnancy. Behaviours particularly relevant to HPV transmission are: early age of sexuall debut, poor contraceptiv/condom use, multiple sexual partners, certain sexual practices and the use of substances such as alcohol and drugs. Adolescents may not have sufficient cognitive skills to foresee risks in sexual relationships and this may be compounded by unrealistic perceptions of themselves as relatively invurnerable.Methodology We want to do something for that young population for education of Human Papillomavirus and sexuall responsible behaviour, so we organized multemedia presentations Name of the project „Knowledge is pleasure’.
