In order to amalgamate research findings on HIV/AIDS in Nigeria as well as the trend of the infection in a concise manner, we reviewed published articles on the HIV/AIDS situation in Nigeria. We categorized this review into several subheadings. The HIV prevalence rate has continued to rise steadily from less than 0.1% in 1987, to 5.8% in 2001, with a slight decrease in 2003 to 5.0%. Although the knowledge about HIV and its mode of transmission is widespread, it is however disheartening to note that this did not result into appreciable attitudinal change and behavior modification among Nigerians. Both HIV-1 and HIV-2 have been identified in Nigeria, with HIV-1 being the predominant type. Furthermore, several subtypes like subtypes A, B, C, G and J have been identified in Nigeria, with several recombinant forms like the CRF02_AG; the major ones being A, G and CRF02_AG. HIV-infected patients in Nigeria are also co-infected with other viral and bacterial infections, the commonly reported ones being co infections with hepatitis B and C. Although treatment of infected patients has increased recently, more effort is needed, especially in the area of patients monitoring, to maximize the benefits of ART in Nigeria. Finally, Nigeria has made appreciable efforts in vaccine development and candidate HIV DNA vaccines have been developed utilizing the sequences from predominant subtypes, and these candidates have been shown to be immunogenic in animal models. It is therefore clear that only the integration of prevention and antiretroviral research programmes into a coherent programme that is needed to address the public health needs that HIV/AIDS crisis represents for Nigeria.
