Rubia Akhtar Brishti, 18, spent hours rocking her one-year-old son, Minhaz, trying to soothe the searing pain and gasping breaths that had overtaken him. He had arrived at the hospital with a high fever and a rash that covered his entire body, struggling for every breath.
Brishti is one of thousands of parents who have flooded the capital city of Dhaka seeking urgent care as a severe Bangladesh measles crisis unfolds. At the DNCC Hospital in Mohakhali—a facility originally established to handle Covid-19 patients—the pediatric wards are now filled with the sounds of coughing and the cries of children battling one of the world’s most infectious diseases.
Since March 15, at least 143 people have died in the outbreak, the vast majority of whom were children. With more than 12,000 suspected cases, health officials describe this as the worst surge the South Asian nation has seen in two decades.
The crisis is not merely a medical failure but a systemic one. A critical measles vaccination drive scheduled for 2024 was delayed following the violent uprising that toppled the autocratic government of Sheikh Hasina. This political instability created a vacuum in public health delivery, leaving thousands of infants unprotected and paving the way for the virus to tear through densely populated areas.
The Science of a Super-Spreader
As a physician, it is important to understand that measles is not a simple childhood rash. It is a highly contagious viral infection transmitted through respiratory droplets—coughs and sneezes—that can linger in the air for hours. For an unvaccinated child, the risk of infection upon exposure is nearly 90%.
While the hallmark of the disease is the characteristic red rash, the true danger lies in the complications. The virus can lead to severe pneumonia, permanent hearing loss, and brain swelling (encephalitis). In the wards in Dhaka, the sight of mothers holding nebulizers over their children’s mouths underscores the prevalence of severe respiratory distress, a common and often fatal complication in malnourished or unvaccinated populations.
The tragedy is compounded for families like that of Nusrat Jahan. Having lost her vaccination cards, Jahan missed the window for her infants’ shots. Now, both of her children are hospitalized in different wards—one on the first floor and one on the second—leaving her torn between two crying babies.
The Herd Immunity Gap
Vaccines are most effective when they achieve “herd immunity,” a threshold where enough of the population is immune to stop the virus from spreading to those who cannot be vaccinated. For measles, the World Health Organization (WHO) states that a 95% coverage rate is required to prevent outbreaks.
Bangladesh has fallen dangerously short of this mark. According to government health services spokesperson Zahid Raihan, vaccination coverage last year plummeted to just 59%.
The current infection data reveals a frightening lack of protection among the sick. Raihan noted that among the children currently affected by the outbreak, only 17% had received a single dose of the vaccine, and a mere 11% had received the necessary second dose. This lack of coverage means that even those with a single dose remain vulnerable when the surrounding community lacks immunity.
| Metric | Current Status / Value | Required for Herd Immunity |
|---|---|---|
| Overall National Coverage (Last Year) | 59% | 95% |
| Affected Children (Single Dose) | 17% | N/A |
| Affected Children (Two Doses) | 11% | N/A |
High-Risk Zones and Systemic Failures
The outbreak has hit the hardest in areas where overcrowding meets limited healthcare access. Golam Mothabbir of Save the Children Bangladesh identified the capital, Dhaka, and the refugee camps of Cox’s Bazar as the primary epicenters. The camps, which house more than a million people in cramped conditions, provide an ideal environment for an airborne virus to spread rapidly.
For many, the gap in coverage was not a choice but a failure of supply. Yasmin Khatun, the grandmother of one-year-old Safwan, recounted her attempts to protect her grandson. She stated that when she took the baby to the local health center, there were no measles vaccines available.
This shortage, combined with the administrative collapse during the political transition in 2024, has left a generation of children exposed. When vaccine campaigns are not sustained, the “immunity gap” grows, creating a reservoir of susceptible hosts that ensures the outbreak continues to spread.
Emergency Response and Next Steps
In an effort to contain the surge, health authorities, in collaboration with UN agencies, launched an emergency measles-rubella campaign on April 5. The initiative aims to protect more than 1.2 million children in the hardest-hit regions.
Although, the success of this campaign depends on reaching the most marginalized populations—those in rural villages and the displaced persons in Cox’s Bazar—who have historically been overlooked by centralized health drives. Without a sustained, nationwide effort to restore the 95% coverage threshold, pediatric wards are expected to remain overwhelmed.

Public health officials are expected to provide the next update on vaccination rates and case numbers following the completion of the current emergency phase of the rubella-measles campaign. Monitoring will focus on whether the 1.2 million target is met and if new clusters emerge in the refugee settlements.
