Standards of healthcare in Afghanistan have improved significantly since the fall of the Taliban, but security continues to play a large role in determining access to and quality of care provided.

In the last 10 years, child mortality rates have fallen by half, with about one in 10 children dying before their fifth birthday.

In 2003 there were 450 health facilities, including hospitals, in the Central Asian nation. Today that number has tripled to 1,800.
