HIV/AIDS is a major health concern in Africa with half of new infections occurring in young people. This study aimed at assessing knowledge and attitude of Nigerian undergraduate towards voluntary HIV counseling and testing (VHCT) with the null hypothesis that knowledge and personal characteristics do not influence attitude. Descriptive study design was used. Information were collected from 174 undergraduates (from selected University) using structured questionnaire (78% reliability). All analyses were at p?0.05. Result showed that most of the respondents (53%) visited the health counselor for VHCT only once particularly to fulfill admission procedure. Moderate level of knowledge of HIV/AIDS was observed among the respondents and poor attitudes toward VHCT. Factors responsible for the poor attitudes includes: peer influence and assumed public stigmatization. Positive and significant relationship was found between knowledge level and attitudes towards VHCT. The study concludes by emphasizing that HIV awareness drive by Nigerian institutions should be more intentional about increasing the knowledge of the youth especially as regards risky sexual behaviour and need for routine testing. Furthermore, Institutional policy framework combining parental and institutional guardians and counseling in combating HIV/AIDS in Nigeria should be explored.
