The health attitudes, attributes and behaviours that are developed and cemented during adolescence, which begins at age 10, will define a girl’s health outcomes throughout her life. Positive choices during this critical period in a girl’s life, and access to youth-friendly health services, have lifelong effects. Strikingly, an adolescent girl is more likely to die from AIDS than any other cause (World Health Organization, n.d.). In 2013, two thirds of the 250,000 new HIV infections among adolescents between the ages of 15 and 19 were among girls.
