“Changing risky sexual behaviour of the population is the main task in the prevention of sexually transmitted infections”.

Sexually transmitted infections (hereinafter referred to as STIs) are a group of diseases that are primarily transmitted during sexual contact. STIs are extremely widespread throughout the world. WHO experts estimate that every sixth inhabitant of the planet suffers from some form of sexually transmitted disease. There are over 30 infections in total. In addition to long-known diseases (syphilis, gonorrhea, trichomoniasis, pubic pediculosis), new diseases have recently been discovered: genital herpes, chlamydia, human papillomavirus (hereinafter referred to as HPV), and ureaplasmosis. These diseases often have no obvious clinical manifestations, hence they are also called "hidden" infections.

According to the causative agent, STIs are divided into 4 groups:

1. Viral (HPV, herpes, hepatitis);

2. Fungal ("thrush" or candidiasis);

3. Bacterial (gonorrhea, chlamydia, syphilis, and others);

4. Parasitic (pubic lice).

In the Vitebsk region, over the past year, 71 cases of syphilis, 128 cases of gonorrhea, and 120 cases of HIV have been registered. The highest incidence among STIs is caused by 8 pathogens of 4 infections: syphilis, gonorrhea, chlamydia, and trichomoniasis are currently curable; the rest, which are viral in nature, are difficult to cure (HIV, HSV – herpes simplex virus, HPV, hepatitis B). 70% of those infected are young people under 29 years of age. However, with HIV infection in 2023, 28.3% were registered in the age group of 30-39 years and 35.8% in the age group of 40-49 years.

STIs directly affect sexual and reproductive health, lead to infertility, oncological diseases, and complications during pregnancy, and also increase the risk of HIV infection. Worldwide, over 311,000 deaths from cervical cancer occur each year as a result of human papillomavirus infection. Every day, there are over 1 million new STI infections, most of which are asymptomatic.

We conducted a survey of students in secondary schools in Vitebsk. To the question: "Did you use a condom during sexual contact?" – 70% of respondents answered sometimes or never. By the age of 16, 53.3%
