Level 1 — Absolute Beginner

Measles is a very bad illness. It is killing children in Bangladesh. More than 1,000 children have died since March.

Almost 190,000 people are sick. Doctors say this is the biggest measles problem in the world right now.

A vaccine can stop measles. Nurses gave the vaccine to 18 million children. But about 4 million children did not get it.

Health workers will start again on 25 September. They want to find every child.

Level 2 — Elementary

Bangladesh is fighting the largest measles outbreak in the world. Since March, the disease has killed more than 1,000 children and made almost 190,000 people sick. The country has about 178 million people.

Measles spreads very easily through the air. A child with measles gets a high fever and a red rash. Most children recover, but some become very ill and do not survive.

In April, the government started an emergency vaccination campaign. Teams gave the vaccine to 18 million children. However, official numbers show that around 4 million children were never reached. Teams are still looking for them.

A new round of vaccination will begin on 25 September. Doctors hope it will finally stop the outbreak.

Level 3 — Intermediate

Bangladesh is in the grip of what the US Centers for Disease Control and Prevention describes as the largest measles outbreak anywhere in the world. Since March, the virus has killed more than 1,000 children and infected close to 190,000 people in a nation of roughly 178 million.

The outbreak did not appear from nowhere. Routine childhood immunisation and vaccine supply were disrupted across 2024 and 2025, while the country went through political turmoil following the uprising that removed former prime minister Sheikh Hasina. Millions of infants missed their scheduled doses during those two years, leaving a large pool of children with no protection at all.

The pattern of deaths shows who is most at risk. At one hospital, 49 of the 57 children who died were younger than 15 months, and 31 were younger than nine months, which is the age at which children in Bangladesh normally receive their first measles and rubella dose. Bangladesh also has one of the highest rates of childhood malnutrition in Asia, and malnutrition sharply raises the chance that measles turns severe.

An emergency campaign launched in April vaccinated 18 million children, but official figures show that roughly 4 million were never reached. Teams are still searching for those children, and a fresh nationwide round is due to start on 25 September.

severe

Very serious or very bad.

Level 4 — Advanced

The measles epidemic now unfolding across Bangladesh has passed a grim threshold: more than a thousand children dead since March, with close to 190,000 recorded infections in a country of some 178 million. American disease investigators rank it as the largest measles outbreak currently under way anywhere on earth, and its arithmetic is less a story about a virus than a story about an interrupted system.

Measles is unforgiving of gaps. It is among the most transmissible pathogens known to medicine, and epidemiologists generally hold that immunisation coverage must sit above ninety per cent to keep it from circulating freely. Bangladesh fell beneath that line during 2024 and 2025, when routine childhood immunisation and vaccine supply chains were disrupted amid the political turmoil that followed the uprising against former prime minister Sheikh Hasina. Each month of interrupted coverage deposited another cohort of unprotected infants into the population, and the virus eventually found them.

The demographic signature of the dead makes the mechanism painfully legible. At a single hospital, forty-nine of fifty-seven fatalities were children under fifteen months, and thirty-one were under nine months, the age at which the first measles and rubella dose is scheduled in Bangladesh. These are children who were, by design, too young to be protected, and who would ordinarily have been shielded by the immunity of everyone around them. Compounding the danger, Bangladesh carries one of Asia's heaviest burdens of childhood malnutrition, a condition that markedly increases both the likelihood of severe complications and the probability that those complications prove fatal.

The state's response has been substantial without being sufficient. An emergency drive launched in April delivered vaccine to eighteen million children, an undertaking of genuine scale; yet official figures concede that roughly four million were never reached, and outreach teams remain in the field searching for them. A renewed nationwide round is scheduled to begin on 25 September. Whether it closes the remaining gap will determine not merely how this outbreak ends, but how quickly the country can rebuild the routine coverage whose collapse made the epidemic possible.
