Introduction Sexually Transmitted Infections are widespread, and have effects on the reproductive and sexual health of the general population particularly youths and adolescents. The study was done to assess the level of knowledge, perception and attitudes towards STI’s by undergraduate students. The objective was to understand and describe the drivers of sexual behaviour amongst university undergraduates and gain an insight into their perception of sexually transmitted infections.

Methods This was a cross-sectional study. A structured self-administered questionnaire on risk factors for STI’s was given to respondents to answer. The study was conducted in October 2016.

Results The mean age of the students (n=310) was 17.8 years+/-1.77 SD.: males were 0.39 times more likely to be sexually active than females [p=<0.001, X²=15.0, CI=0.23–0.69], females were 2.18 times more likely to join an abstinence club [p=0.005, X²=7.6, CI=1.24–3.81]. Males were 0.3 times more likely to believe condoms protect against all STI’s [p =<0.001, X²=10.93, CI=0.14–0.63] and were 2.61 times more likely to use condoms regularly [p=0.002, X²=8.94, CI=1.38–4.94].

Conclusion The rates of sexual exposure and unprotected sex are still high among our youths. We need to invest in treatment and prevention programs regarding STI’s in the young and identify the barriers that prevent access to care such as a lack of appropriate and effective STI control programs. STIs are preventable and significant reductions in new infections are possible and needed. Prevention can minimise their negative impact and reduce healthcare costs.
