AIDS, tuberculosis, malaria: the situation in figures

Significant progress has been made against the major epidemics but the situation remains fragile.

AIDS

Although almost 60% of the 37 million people living with HIV worldwide now have access to antiretroviral treatment and AIDS-related deaths have halved since 2005, the disease still kills over one million people per year.

AIDS is the leading cause of death among women aged 15-44 around the world and among adolescents (aged 10-19) in Sub-Saharan Africa, and the number of people living with HIV continues to climb each year.

Tuberculosis

According to the WHO, multidrug-resistant tuberculosis (MDR-TB) is one of the biggest threats to global health security. While the number of tuberculosis-related deaths has fallen by 37% since 2000, it is currently the leading cause of death from a single infectious agent, with 1.6 million victims in 2016. In 2017, 25% of tuberculosis cases and 75% of MDR-TB cases went undiagnosed.

Malaria

Half of the world’s population, about 3.2 billion people, live in regions in which there is a risk of malaria transmission. Pregnant woman and children continue to be the most affected subgroups. Sub-Saharan Africa remains the hardest-hit region, accounting for 91% of all malaria deaths in 2017 (WHO, 2017). In 2016, the WHO warned about the risk of a further outbreak of the pandemic, with the number of cases up by five million on 2015.
