UN agency coordinating international public health, including the Framework Convention on Tobacco Control and the Cervical Cancer Elimination Initiative. - Leading global cancer prevention strategy

Four in ten cancer cases worldwide could be prevented. That finding, from the World Health Organization's International Agency for Research on Cancer, marks the first time researchers have quantified the combined burden of behavioral, environmental, occupational, and infectious causes of cancer using global data from 185 countries. The analysis, published in Nature Medicine ahead of World Cancer Day, estimates that 7.1 million cancer cases in 2022 were linked to just 30 modifiable risk factors.

Global health authority setting trachoma elimination targets and validating country achievements. - Coordinating global elimination campaign

For the first time since records began, fewer than 100 million people need treatment for trachoma—a bacterial eye disease that's been blinding humans since ancient Egyptian times. The number at risk has cratered 94% since 2002, from 1.5 billion to 97 million. Twenty-seven countries have eliminated it entirely, making trachoma one of the success stories celebrated at World NTD Day 2026 on January 30.

UN agency responsible for international public health, disease surveillance, and coordinating pandemic response. - Primary coordinator of global health efforts

In 1950, the average human lived 47 years. Today, it's 73. The global age-standardized mortality rate has dropped 67% over that span—driven not by a single breakthrough but by the compounding effects of vaccines, clean water, antibiotics, and basic sanitation reaching billions of people who previously lacked access. Lower respiratory infections (LRIs)—once the leading cause of infectious disease death—killed 2.5 million people in 2023, down 33% among children under five since 2010.

Coordinates the UN Maternal Mortality Estimation Inter-Agency Group and sets global health targets. - Lead agency for maternal mortality estimation and target-setting

In 1990, approximately 532,000 women died each year from pregnancy and childbirth complications. By 2015, that number had fallen to 303,000—a 44% reduction in the maternal mortality ratio, from 385 to 216 deaths per 100,000 live births. The decline represents one of the largest coordinated public health efforts in history, driven by expanded access to skilled birth attendants, emergency obstetric care, and basic medical interventions like antibiotics and blood transfusions.

UN agency coordinating international public health, setting standards, and tracking global health statistics. - Primary global health coordinating body

For most of human history, the average person could expect to live about 30 years. Two centuries of accumulated advances—clean water, sanitation, vaccines, antibiotics, nutrition, and poverty reduction—have more than doubled that figure to 72 years globally. The change is so comprehensive that the global average today exceeds what the healthiest country achieved in 1950.

UN specialized agency leading global health initiatives including immunization expansion and child mortality reduction. - Active; coordinates global immunization and child health programs

In 1900, one in seven babies born in the United States or United Kingdom died before their first birthday. By 2017, the rate had fallen to roughly 4-6 per 1,000—a decline exceeding 95%. This transformation ranks among the most consequential achievements in human history, fundamentally altering how families experience childbirth and early childhood.

UN agency coordinating global health responses and setting vaccine efficacy targets. - Set 75% efficacy target; approved two vaccines for rollout

NIH researchers discovered a new class of antibodies that attack malaria parasites at a never-before-targeted site. The antibody MAD21-101 protected four out of five mice from infection and works differently than existing vaccines, binding to a cryptic protein fragment exposed only after the parasite undergoes a specific chemical transformation called pyroglutamylation. The breakthrough opens a fresh avenue in the decades-long hunt for a highly effective malaria vaccine.
