Global health organisations are celebrating a big victory: measles mortality fell by 88% between 2000 and 2024, saving approximately 59 million lives. However, a concerning increase in new infections offsets the respite, revealing major flaws in the world's immunisation defences. The World Health Organisation (WHO) says that an estimated 95,000 people—mostly children under the age of five—died from measles in 2024, a disease that can be avoided with a low-cost, highly effective vaccination. 

The number of infections is rapidly increasing and spreading. The World Health Organisation (WHO) predicts that the pandemic in 2019 will affect 11 million individuals in 2024, an increase of over 800,000 from before. The development reveals a concerning paradox: fewer deaths overall, but considerably more potential for the virus to spread and create outbreaks. 

"Measles is the world's most contagious virus, and these data show once again how it will exploit any gaps in our collective defences against it," said WHO Director-General Dr. Tedros Adhanom Ghebreyesus. "Measles does not respect borders, but when every child in every community is vaccinated against it, costly outbreaks can be avoided, lives can be saved, and this disease can be eliminated from entire nations." 

Measles spreads through the air whenever an infected person breathes, coughs, or sneezes. Because the virus is extremely contagious, even a small number of unvaccinated youngsters can create widespread epidemics. While most children survive the infection, significant complications are nevertheless common. These include pneumonia, blindness, and encephalitis, a deadly brain swelling that can result in permanent impairment. 

Regional data provide a mixed picture. Cases increased by 86% in the Eastern Mediterranean, 47% in Europe, and 42% in Southeast Asia compared to 2019. In contrast, the African region recorded a 40% decrease in incidence and a 50% decrease in deaths, thanks in part to higher vaccination coverage. However, Africa and the Eastern Mediterranean continue to contain the majority of the 30 million children who are underprotected. 

The underlying issue remains poor vaccination. In 2024, just 84% of children received their first measles vaccination, and 76% received the essential second dose. The WHO recommends 95% coverage with two doses to prevent transmission. Falling coverage has left healthcare systems vulnerable, and measles is frequently the first disease to resurface when vaccinations fail. 

The number of nations reporting significant outbreaks is rapidly increasing—59 countries by 2024, nearly double the number seen in 2021. Surveillance systems are being pushed. Although the World Health Organization's Global Measles and Rubella Laboratory Network screened over 500,000 samples in 2024, funding shortages threaten to increase immunity gaps and delay outbreak response. 

Despite setbacks, the movement towards elimination continues. By the end of 2025, 96 countries had eradicated measles, including numerous Pacific nations and the first confirmed African country. Nevertheless, the globe is still a long way from meeting the Immunisation Agenda 2030 targets, which call for increased political commitment, steady finance, and high-coverage vaccination programs.
