Bangladesh dengue outbreak accelerates as hospitals come under strain

Bangladesh’s dengue outbreak is accelerating, with hospitals facing a sharp September surge and health experts warning that the peak may still lie ahead.

Health Ministry data recorded 42,590 hospitalisations and 117 deaths in 2026. In the latest 24-hour period, at least four dengue patients died and 1,558 others were admitted, the highest daily admission figure recorded this year.

The peak has not been reached yet. If the current trajectory continues, September may become the worst month of the year for dengue infections.

Professor Kabirul Bashar, a medical entomologist at Jahangirnagar University, said his surveillance and forecasting model suggested September hospitalisations could exceed 30,000 if current trends continued. Weather conditions could support transmission into October, he said. “The peak has not been reached yet,” Bashar said. “If the current trajectory continues, September may become the worst month of the year for dengue infections.”

The surge has revived concerns after Bangladesh’s deadliest dengue outbreak in 2023. It is also placing additional pressure on a healthcare system already dealing with a nationwide measles outbreak that has killed nearly 1,000 children in 2026.

I was terrified. As a father, it was unbearable to watch my child getting worse without knowing where he could be admitted.

For Zahid Hasan, the crisis became personal when his four-year-old son developed a high fever and was diagnosed with dengue. Hasan took the child to three government hospitals but could not find a bed. He eventually secured one at a private hospital with help from a relative. The boy received seven bags of blood and plasma and remains weak as he recovers.

Those days were a nightmare for us. We were constantly afraid something could happen to him.

Professor Tarek Alam, a Dhaka physician treating dengue patients, warned that people should not ignore abdominal pain, dizziness or unusual lethargy. Patients can deteriorate rapidly after their fever falls, suffering plasma leakage, low blood pressure, shock or severe bleeding.

Experts say Aedes mosquitoes are spreading beyond Dhaka and other major cities. Cases have now been reported in all 64 districts, although the capital still accounts for the largest share. Prime Minister Tarique Rahman has ordered nationwide clean-up and awareness campaigns, urging residents to remove stagnant water.

Patients are flooding hospitals, and warning signs such as abdominal pain, dizziness and unusual lethargy must not be ignored.
