Experts have warned Bangladesh that deadly outbreaks of diphtheria, whooping cough and polio could follow an ongoing measles epidemic that has already killed over 1,200 children, according to a report seen by AFP on Monday.
"The measles outbreak is a litmus test and a warning sign of a deteriorating immunization system," said the report by an independent committee of national and international experts, which carried out its research earlier in October.
Bangladesh has struggled since March to contain the outbreak, which has killed more than 1,200 children and infected 220,000 people, making it the country's deadliest in decades, according to the Directorate General of Health Services (DGHS).
"If no urgent mitigation measures are taken, it is only a matter of time before there are large outbreaks of pertussis (whooping cough), diphtheria and even vaccine-derived poliovirus," added the report, which has been submitted to the government.
The health ministry pledged action on Monday.
"We are going to recruit vaccinators as quickly as possible as the first step towards implementing the recommendations," spokesman Zahid Raihan told AFP.
The government, supported by the World Health Organization (WHO), UNICEF, the Gavi vaccine alliance and other partners, deployed a 70-member team earlier this month to assess the country's immunisation programme.
The review found that just 82 percent of children were fully immunised, well below the national target of 95 percent. Around 40 percent of vaccinator posts remain vacant.
Bangladesh was long considered an immunisation success story. Since its programme began in 1979, the country has eliminated polio and neonatal tetanus and controlled rubella and hepatitis B.
A measles vaccination campaign planned for 2024 was delayed by the revolution that toppled former prime minister Sheikh Hasina, while strikes and political instability further disrupted a campaign in 2025.
Authorities have since launched a mass vaccination drive, but cases continue to climb.
Measles spreads easily through coughs and sneezes and has no specific treatment. Complications include brain swelling and severe breathing problems, with young children particularly vulnerable.
Whooping cough can cause severe illness and death in infants. Diphtheria can obstruct breathing and damage the heart and nerves, while vaccine-derived poliovirus can cause paralysis in under-immunised populations.
