In 2023, the world saw an increase in measles cases, with an estimated 10.3 million people infected, showing a 20% rise from the previous year
This new surge, caused by gaps in immunisation coverage, has left communities vulnerable to one of the world’s most contagious viruses, which remains preventable through vaccination.
Protecting people from measles through vaccination
Despite the availability of a highly effective vaccine, over 22 million children missed their first dose of the measles vaccine in 2023. Around 83% of children globally received their first dose, but only 74% received the second, which is necessary to provide full protection, the World Health Organisation reported.
Experts say a vaccination coverage of at least 95% is needed worldwide to prevent widespread outbreaks and safeguard populations, especially the most vulnerable children.
Measles outbreak
Measles outbreaks have been particularly severe in countries with lower immunisation rates. In 2023, 57 countries reported significant outbreaks, nearly 60% more than in the previous year.
The African region was hit hardest, with nearly half of all large outbreaks occurring there. The disease has affected countries across the globe, except the Americas, which have seen progress in eliminating measles.
The rise in measles cases has led to a tragic increase in deaths, especially among young children. An estimated 107,500 people, mostly children under five, died from measles in 2023, although this represents an 8% decline from the previous year.
Complications caused by measles
While this decrease is a hopeful sign, experts warn that too many children are still dying from this entirely preventable disease. Even among survivors, serious complications such as blindness, pneumonia, and brain damage can occur.
With the goal of measles elimination still in sight, the WHO’s Immunisation Agenda 2030 faces significant challenges. Some countries, however, including Brazil, have successfully eliminated measles. Global health leaders urge all countries, particularly in high-risk regions like Africa and the Eastern Mediterranean, to urgently ramp up vaccination efforts, strengthen disease surveillance, and ensure that every child receives both doses of the measles vaccine.
To prevent further loss of life and protect children worldwide, investment in vaccination and immunisation programs is important.
