There has been some progress over the past three decades in the fight against HIV/AIDS and the incidence rate has declined trend from 3.1% in 2010 to 2.23% in 2013, to 1.94% in 2015, but the HIV prevalence of 26% among 15-49 year olds is among the highest in the world. This has translated into increased health spending and high numbers of orphaned and vulnerable children requiring social protection. It is projected that the share of the population living in towns and cities will rise to 26.5% by 2030.
