In health education on utilizationof ITNs in Bayelsa and Rivers states; as well as on HIV/AIDS infection in Northern Nigeria. Statistically, the studies followed a quantitative method.

On HIV, community-based television, and radio awareness programs on the use of condom influenced the reduction of HIV/AIDS infection by up to 30%. In conclusion, the preliminary reports indicatethatantioxidant vitamins and iron supplementation ameliorated anaemia and VI. Public health awarenesscampaign influenced behavioural change wheel on use of ITNs as well asuse of condom for the reduction of HIV/AIDS infection in Nigeria.
