Bangladesh once stood as a global example in reducing measles-related deaths through strong immunization programs. For decades, sustained vaccination campaigns under the Expanded Programme on Immunisation (EPI) brought the disease under control. However, in 2026, the country is facing a troubling resurgence of measles—one of the most contagious viral diseases known to humanity.
Since mid-March 2026, thousands of suspected cases and over a hundred child deaths have been reported across the country. The outbreak has spread rapidly, affecting a majority of districts and overwhelming healthcare facilities. What makes this situation more alarming is that measles is entirely preventable through vaccination.
This article explores the causes behind the recent measles outbreak in Bangladesh and examines the steps taken by the government, including a nationwide emergency vaccination campaign, to combat this public health crisis.
Understanding Measles: A Highly Contagious Threat
Measles is a viral disease that spreads through respiratory droplets and airborne transmission. It is so contagious that even brief exposure can lead to infection, especially among unvaccinated individuals. Children under five years of age are particularly vulnerable, often suffering severe complications such as pneumonia, encephalitis, and even death.
The disease is preventable with two doses of the measles-containing vaccine, which can provide up to 97% protection. Yet, as recent events in Bangladesh demonstrate, even small gaps in vaccination coverage can lead to large-scale outbreaks.
Current state
Bangladesh is currently experiencing one of its worst measles outbreaks in over a decade. Reports indicate:
- Over 8,500 suspected cases nationwide since March 2026
- More than 100 deaths, mostly among children
- Thousands of hospitalizations across the country
In addition, earlier estimates suggested more than 6,400 affected children across dozens of districts. The outbreak has spread to nearly the entire country, signaling a widespread public health emergency.
Causes of the Measles Outbreak
The resurgence of measles in Bangladesh did not happen overnight. It is the result of multiple systemic failures and gaps that accumulated over several years.
- Decline in Vaccination Coverage
One of the primary causes of the outbreak is the decline in routine immunization coverage. Between 2024 and 2025, Bangladesh experienced a significant drop in measles vaccination rates due to a nationwide shortage of measles-rubella (MR) vaccines.
In fact, vaccination coverage dropped dramatically—from around 90% in 2020 to nearly 57% in 2025. This created a large population of unprotected children, making the country vulnerable to an outbreak.
- Immunization Gaps and Missed Children
Even before the vaccine shortage, gaps in immunization coverage were emerging. Many children missed routine vaccinations due to logistical challenges, lack of awareness, or healthcare access issues.
Experts warn that “even small gaps in immunization coverage can trigger outbreaks.” These gaps accumulate over time, eventually reaching a tipping point where herd immunity breaks down.
- Absence of Supplementary Immunization Campaigns
Bangladesh had previously conducted nationwide supplementary immunization campaigns to ensure that no child was left behind. However, no such large-scale campaign was conducted after 2020.
This absence allowed immunity gaps to widen, especially among older children who may have missed earlier doses.
- Impact of COVID-19 Pandemic
The COVID-19 pandemic disrupted healthcare systems worldwide, and Bangladesh was no exception. Resources and attention were diverted toward pandemic response, leading to interruptions in routine immunization services.
Globally, millions of children missed essential vaccines during this period, increasing the risk of outbreaks like measles.
- Policy Missteps and Governance Issues
Health experts have pointed to policy failures and mismanagement as contributing factors. Delays in procurement, lack of planning for vaccination campaigns, and administrative disruptions weakened the immunization system.
Additionally, political instability and funding constraints further hampered vaccination efforts in recent years.
- Vulnerability of Infants
A significant number of cases have been reported among infants below nine months of age—children who are not yet eligible for routine measles vaccination.
This highlights the importance of herd immunity: when vaccination coverage is high, even those who cannot be vaccinated are protected. When coverage drops, these vulnerable groups are the first to suffer.
Government Response: Emergency Vaccination Campaign
In response to the rapidly escalating outbreak, the Government of Bangladesh has launched an emergency measles-rubella vaccination campaign in collaboration with international partners such as UNICEF, WHO, and Gavi.
- Target Population
The campaign aims to vaccinate over 1.2 million children aged 6 months to 5 years—those most at risk of infection and severe disease.
Importantly, the vaccine is being provided free of charge, regardless of previous vaccination status.
- Phased Implementation
The campaign is being rolled out in phases:
- Phase 1: 30 high-risk upazilas in 18 districts
- Phase 2: Expansion to major city corporations
- Phase 3: Nationwide rollout starting in May 2026
This phased approach allows authorities to prioritize hotspots while gradually scaling up efforts.
- Identification of High-Risk Areas
The government identified 30 “hotspots” where infection rates were particularly high. These areas were prioritized for immediate intervention, ensuring that limited resources are used effectively.
- Strengthening Health Workforce
To address the crisis, the government has mobilized healthcare workers across the country. In some cases, leave for medical staff has been cancelled to ensure adequate manpower for vaccination and treatment efforts.
- Public Awareness Campaigns
Authorities are urging parents to vaccinate their children and seek medical care at the first sign of symptoms. Public awareness campaigns are being conducted through media, community outreach, and healthcare facilities.
- Collaboration with International Partners
The involvement of organizations like UNICEF, WHO, and Gavi has been crucial. These partners provide technical support, funding, and vaccine supplies, helping Bangladesh mount a rapid response to the outbreak.
Early Impact of the Campaign
Initial reports indicate a strong response to the vaccination campaign. On the first day alone, tens of thousands of children were vaccinated, achieving over 95% of the daily target in some areas.
This suggests that public trust in vaccines remains high, which is a positive sign for the success of the campaign.
Challenges Ahead
Despite the government’s swift action, several challenges remain:
- Reaching remote and underserved populations
- Ensuring vaccine supply continuity
- Combating misinformation and vaccine hesitancy
- Strengthening routine immunization systems
Experts warn that emergency campaigns alone are not enough. Long-term solutions are needed to prevent future outbreaks.
Lessons for the Future
The measles outbreak in Bangladesh serves as a stark reminder of the importance of sustained investment in public health. Key lessons include:
- Routine immunization must never be neglected
- Vaccine supply chains need to be resilient
- Supplementary campaigns should be conducted regularly
- Public health systems must be prepared for crises
As one expert noted, measles deaths are not just a medical issue—they reflect broader weaknesses in the healthcare system.
Conclusion
The ongoing measles outbreak is both a tragedy and an opportunity. It has exposed critical gaps in Bangladesh’s immunization system, but it has also prompted decisive action from the government and its partners.
If the current vaccination campaign succeeds and is followed by sustained improvements in routine immunization, Bangladesh can once again regain control over measles. However, failure to address the root causes of the outbreak may lead to repeated crises in the future.
Ultimately, the fight against measles is not just about vaccines—it is about commitment, coordination, and the collective will to protect every child.
