Bangladesh Measles Cases Rising Warning Signs Vaccine & Protection Tips
Circumstance at a Glance
On 4 April 2026, the National International Health Regulations (IHR) Focal Point for Bangladesh informed WHO about a nationwide increase in measles cases. The outbreak affected 58 out of 64 districts across all eight divisions of Bangladesh.
Between 15 March and 14 April 2026:
- 19,161 suspected measles cases were reported
- 2,973 laboratory-confirmed measles cases were identified
- 166 suspected measles-related deaths occurred
- 30 confirmed measles-related deaths were recorded
- The Case Fatality Rate (CFR) remained around 1%
Most affected children are under 5 years of age, especially:
- Children under 2 years
- Infants below 9 months
- Unvaccinated children
WHO has assessed the national risk level as High due to widespread transmission and immunity gaps.
Description of the Situation
Nationwide Spread of Measles
Bangladesh has witnessed a sharp rise in measles infections since January 2026. Cases have now been reported in:
- 58 out of 64 districts
- All 8 divisions nationwide
The outbreak shows sustained community transmission throughout the country.

- Dhaka: 8,263 cases
- Rajshahi: 3,747 cases
- Chattogram: 2,514 cases
- Khulna: 1,568 cases
In Dhaka, major hotspots include:
- Demra
- Jatrabari
- Kamrangirchar
- Korail
- Mirpur
- Tejgaon industrial and slum areas
Hospitalizations and Deaths
The outbreak has placed major pressure on healthcare systems.
- 12,318 hospital admissions
- 9,772 hospital discharges
- 166 suspected deaths
- 30 confirmed measles deaths
Most deaths occurred among unvaccinated children younger than 2 years.
Epidemiology of Measles
What is Measles?
Measles is a highly contagious viral disease that affects people of all ages. It remains one of the leading causes of death among young children worldwide.
The virus spreads through:
- Airborne transmission
- Respiratory droplets from coughing or sneezing
Common Symptoms of Measles
Symptoms usually appear 10–14 days after exposure and may include:
- High fever
- Runny nose
- Red eyes
- Persistent cough
- Small white spots inside the mouth
- Skin rash spreading from head to lower body
An infected person can spread the virus:
- 4 days before the rash appears
- Up to 4 days after the rash develops
Possible Complications
Although measles is often mild, it can lead to serious complications such as:
- Pneumonia
- Diarrhea
- Ear infections
- Brain inflammation (encephalitis)
- Blindness
- Death
Children suffering from malnutrition or Vitamin A deficiency are at greater risk.
Importance of Measles Vaccination
Measles Vaccine Protection
The measles-containing vaccine (MCV) is safe and highly effective.
WHO recommends:
- Two doses of measles vaccine
- Strong routine immunization systems
- High vaccination coverage in every district
Vaccination protects children from:
- Severe illness
- Complications
- Hospitalization
- Death
Supplementary Immunization Activities (SIAs)
WHO also recommends mass vaccination campaigns to reach children who missed routine immunization services.
These campaigns help:
- Reduce the number of vulnerable children
- Increase population immunity
- Control outbreaks quickly
Public Health Response in Bangladesh
Nationwide Vaccination Campaign
A nationwide Measles-Rubella (MR) vaccination campaign was approved on 30 March 2026.
Campaign Details:
- Started on 5 April 2026
- Initially launched in 30 upazilas
- Covered 18 priority districts
- Expanded nationwide on 20 April
The campaign targets:
- Children aged 6–59 months
- Expanded protection for infants aged 6–8 months
Additional Response Measures
Bangladesh health authorities and WHO implemented several emergency measures:
- Activation of Rapid Response Teams (RRTs)
- Fast-tracked vaccine procurement
- Strengthening routine immunization
- Improving hospital preparedness
- Providing Vitamin A supplementation
- Enhancing infection prevention and control
- Increasing surveillance and case reporting
- Conducting epidemiological investigations
Vitamin A Supplementation
Vitamin A is being provided to all suspected and confirmed measles patients because it helps reduce:
- Severe complications
- Vision problems
- Mortality risk
WHO Risk Assessment
Why the Risk is High
WHO classified the outbreak risk as high because of:
- Ongoing nationwide transmission
- Large immunity gaps
- High numbers of unvaccinated children
- Recent vaccine shortages
- Measles-related deaths
Most infected children were either:
- Unvaccinated
- Partially vaccinated
- Too young to receive the vaccine
Decline in Vaccination Coverage
Bangladesh had previously made major progress toward measles elimination.
Earlier Achievements:
- High MR1 and MR2 vaccination coverage
- Significant reduction in measles cases
However, several factors contributed to the current outbreak:
- Nationwide MR vaccine stockouts during 2024–2025
- Gaps in routine immunization
- Lack of nationwide MR campaigns since 2020
Regional and Global Risk
Cross-Border Transmission Risks
WHO warns about increased risks of international spread because Bangladesh shares borders with:
- India
- Myanmar
Major cities acting as travel hubs include:
- Dhaka
- Chattogram
- Sylhet
- Cox’s Bazar
Situation in Neighboring Countries
Myanmar:
- Large numbers of unvaccinated children
- Ongoing humanitarian crisis
- Weak surveillance systems
India:
- Rising measles cases over recent months
- Active border movement with Bangladesh
Border districts at higher risk include:
- Jashore
- Chapainawabganj
WHO Recommendations
Vaccination Coverage
WHO recommends maintaining at least:
- 95% coverage for the first vaccine dose
- 95% coverage for the second vaccine dose
Stronger Surveillance
- Detect suspected cases quickly
- Improve laboratory testing
- Strengthen border surveillance
- Ensure rapid outbreak response
Protection of High-Risk Groups
WHO advises vaccination for:
- Healthcare workers
- International travelers
- Border workers
- Tourism and transportation staff
- Migrant populations
Hospital Infection Control
- Isolate measles patients
- Prevent overcrowding
- Reduce hospital-based transmission
- Strengthen infection prevention measures
WHO Travel Advice
WHO currently does not recommend restrictions on:
- International travel
- Trade activities
Conclusion
The 2026 measles outbreak in Bangladesh highlights the dangers of declining vaccination coverage and immunity gaps. The rapid spread of the virus among young unvaccinated children has created a major public health emergency.
WHO and Bangladesh health authorities continue strengthening vaccination campaigns, surveillance, and emergency response measures to control the outbreak and prevent further deaths.
