This chapter examines mass media and the promotion of sustainable health in Nigeria, using the COVID-19 experience as a focus. Anchored on the agenda setting theory, the chapter observes that media played an active role in creating awareness at the early stages of the COVID-19 pandemic, but after some time, the media did not pay much attention to sustaining the awareness. The chapter concludes that the media are vital to the promotion of sustainable health in Nigeria and recommends that the mass media must ensure that promotion of sustainable health in Nigeria continues by using all known media platforms to communicate to the people.
