Life expectancy has increased dramatically with the introduction of effective HIV treatment, but the impact has varied in different parts of the world.
Life expectancy in rural Kwazulu-Natal, South Africa, has increased dramatically with the roll out of antiretroviral (HIV) therapy.
The province has a high HIV prevalence (28%).
Investigators measured life expectancy at a population level between 2000 and 2011. Between 2000 and 2003, life expectancy fell from 59 to 52 years.
A programme rolling out antiretroviral therapy started in 2003. By 2011, average life expectancy had increased to 60 years.
