Measles Cases Surge in Conflict Zones Amid Vaccine Misinformation and Aid Cuts

According to Save the Children, measles cases increased over 25% in conflict zones last year, driven by attacks on healthcare, aid cuts, vaccine misinformation, and disruption to health systems.

The organization analyzed World Health Organization data and found that in 2025, 18 countries in conflict recorded over 74,340 cases of measles, compared to about 57,800 in 2024.

These countries, representing only 15% of the child population in the total number of countries reporting measles cases, accounted for 30% of global measles cases, showing how countries in conflict are disproportionately impacted by measles outbreaks.

Save the Children warned that the actual number of cases is estimated to be higher still due to underreporting from disrupted and destroyed health systems.

With World Immunization Week beginning this Friday, the aid agency is calling for renewed global efforts to help vaccines reach children.

As of 2026, more than 14,360 cases of the deadly measles virus have been confirmed across 15 countries facing conflict.

Understanding the Drivers Behind the Surge

Vaccine misinformation and political instability fuel vaccine hesitancy, while armed groups sometimes obstruct immunization efforts for strategic purposes.

These effects extend beyond war zones, as displacement and inadequate healthcare access increase the risk of cross-border outbreaks.

The Role of Misinformation in Vaccine Hesitancy

Misinformation is undoubtedly a major threat in spreading killer childhood diseases like measles, particularly when vaccination rates fall in many parts of the world.

In 2016, the UK had a major public health win when the World Health Organization declared it had eliminated measles. But two years later this status was revoked as cases doubled. Now, the UK is in the midst of a measles emergency with 140 cases reported so far in 2024 alone.

Global Implications and the Need for Action

The increasing rate of misinformation around the measles outbreak and the resurgence of discussions on the origins of the COVID-19 Pandemic call for urgent policy action that helps regulate public health distribution and the ethical and factual distribution of medical information.

Globally, such trends already exist, underscoring the need for coordinated efforts to combat vaccine hesitancy and ensure equitable access to immunization services.

Save the Children’s analysis highlights the urgent need for renewed global efforts to help vaccines reach children in conflict zones, especially during World Immunization Week.

Frequently Asked Questions

What is driving the increase in measles cases in conflict zones?

The increase is driven by attacks on healthcare, aid cuts, vaccine misinformation, and disruption to health systems, as reported by Save the Children.

How does vaccine misinformation contribute to measles outbreaks?

Vaccine misinformation fuels vaccine hesitancy, which reduces vaccination rates and allows measles to spread, particularly when combined with political instability and healthcare access issues.

Why are conflict zones disproportionately affected by measles outbreaks?

Conflict zones account for 30% of global measles cases despite representing only 15% of the child population, due to disrupted health systems, underreporting, and barriers to vaccination access.

What is being done to address the measles surge in conflict zones?

Save the Children is calling for renewed global efforts to help vaccines reach children during World Immunization Week, emphasizing the need for coordinated action to combat vaccine hesitancy and ensure equitable access to immunization services.
