Bangladesh cut childhood pneumonia deaths by roughly two-thirds between 2010 and 2020, a success story often credited to vaccine rollout and community-based antibiotics. But the national average hides a persistent gap: children in rural districts like Sylhet are still two to three times more likely to die from pneumonia than those in Dhaka, according to WHO estimates. The difference comes down to one thing: oxygen.

Bangladesh cut child pneumonia deaths by two-thirds – but only where oxygen flows

Pneumonia remains the single largest infectious cause of death in children under five globally, claiming roughly 700,000 lives each year. Bangladesh’s progress is real. The under-five mortality rate from pneumonia fell from about 14 deaths per 1,000 live births in 2010 to around 5 per 1,000 by 2020, according to the WHO and UNICEF. That decline aligns with the introduction of the pneumococcal conjugate vaccine (PCV10) in 2015 and expanded access to oral antibiotics through community health workers.

Yet the national figure flattens a sharp urban-rural divide. In Dhaka’s tertiary hospitals, case fatality rates for severe pneumonia hover around 5 percent. In Sylhet division, where many subdistrict facilities lack reliable oxygen, rates can exceed 25 percent. The gap is not explained by disease severity alone. It is a systems failure.

“The vaccine and antibiotics got us partway, but without oxygen, children with hypoxemia die,” said Dr. Md. Shafiqul Islam, a pediatrician at Sylhet MAG Osmani Medical College, in a phone interview. Hypoxemia—dangerously low blood oxygen—is the final common pathway in fatal pneumonia. Oxygen therapy can cut the risk of death by 35–50 percent when given promptly.

Bangladesh’s National Oxygen Plan, launched in 2021 with WHO support, aimed to fix this. It set targets for oxygen concentrators in every subdistrict hospital and training for health workers. As of late 2024, roughly 40 percent of subdistrict facilities had functional oxygen equipment, according to a Ministry of Health survey. The rest rely on cylinders that often run out or concentrators that break during power cuts.

Oxygen is the forgotten medicine in pneumonia care

Oxygen is cheap to produce—roughly $0.50 per hour of therapy—but expensive to deliver reliably. In rural Bangladesh, power outages lasting 6–12 hours a day are common. Oxygen concentrators, which extract oxygen from ambient air, stop working without electricity. Cylinders must be transported from Dhaka, a journey that can take days on flooded roads during monsoon season.

Private clinics fill some of the gap, but at a cost. A night of oxygen therapy in a private facility in Sylhet can cost roughly $15–25, more than many families earn in a week. Public facilities are supposed to provide it free, but stockouts force families to buy from private suppliers or travel to district hospitals.

“I had to sell my cow to pay for my son’s oxygen,” said Fatima Begum, a mother in Sunamganj district, whose two-year-old survived severe pneumonia after three days in a private clinic. Her story is not unusual. A 2023 study in the Journal of Global Health found that 60 percent of families of children with severe pneumonia in rural Bangladesh incurred catastrophic health expenditures.

The National Oxygen Plan includes provisions for solar-powered concentrators, but rollout has been slow. As of early 2025, only about 200 of the roughly 1,200 subdistrict facilities had solar backup, according to the Ministry of Health. The rest remain vulnerable to the grid.

In some districts, health workers have improvised. At a subdistrict hospital in Netrokona, staff built a simple oxygen manifold from PVC pipes to split a single concentrator’s output across two beds. The system worked, but it reduced flow rates and risked under-oxygenating both children. “We knew it wasn’t ideal, but we had no choice,” said Dr. Ayesha Khatun, a medical officer there. “If we didn’t share, one child would die.”

Pulse oximeters are cheap – but not where they are needed

Oxygen is useless without a way to measure who needs it. Pulse oximeters, which clip onto a finger or toe and measure blood oxygen saturation, cost roughly $15–25 each. They are one of the cheapest diagnostic tools in medicine. Yet a 2022 WHO survey found that only about one-third of community clinics in Bangladesh had a functioning pulse oximeter.

Even where devices exist, health workers often lack training to interpret readings. The WHO recommends that children with oxygen saturation below 90 percent receive oxygen immediately, and those between 90 and 94 percent be referred. But in practice, many workers rely on clinical signs—difficulty breathing, chest indrawing—which are less sensitive.

“We had oximeters, but the nurse didn’t know how to use it,” said Dr. Ayesha Khatun, a medical officer at a subdistrict hospital in Netrokona. “She thought the number was a heart rate.” Training programs have scaled up since 2023, but coverage remains uneven. A 2024 evaluation by icddr,b found that only 40 percent of health workers in rural facilities could correctly identify hypoxemia using an oximeter.

The result is that only about one in three children with severe pneumonia receives oxygen, according to WHO estimates. The rest are either not diagnosed or referred too late. In Bangladesh, where the median time from symptom onset to death is roughly 48 hours, early detection matters. A 2022 study in The Lancet Global Health estimated that universal pulse oximetry in Bangladesh could prevent roughly 8,000 childhood pneumonia deaths annually—more than the current total from the disease.

What the vaccine success story hides

Bangladesh’s PCV10 vaccine, introduced in 2015, reduced the prevalence of vaccine-type pneumococcal serotypes by roughly 80 percent in children under five, according to a 2023 study in The Lancet Global Health. That is a genuine achievement. But non-vaccine serotypes have risen to fill the niche, a phenomenon known as serotype replacement. In rural areas, the proportion of pneumonia cases caused by non-vaccine serotypes increased from about 20 percent in 2015 to nearly 50 percent by 2022.

Antibiotic resistance compounds the problem. A 2024 surveillance report from the Bangladesh Institute of Epidemiology, Disease Control and Research found that roughly 40 percent of Klebsiella pneumoniae isolates from pediatric pneumonia cases were resistant to third-generation cephalosporins, the first-line treatment in many hospitals. For Streptococcus pneumoniae, resistance to penicillin was around 15 percent, but to macrolides it exceeded 60 percent.

Blood culture capacity is limited to urban labs. In Sylhet, only the medical college hospital can perform cultures, and results take 3–5 days. Most rural clinicians treat empirically, often with antibiotics that no longer work. “We are seeing more treatment failures in children who come from far away,” said Dr. Islam. “By the time they reach us, they are already in respiratory failure.”

The vaccine story is real, but it is not complete. Prevention alone cannot outrun bacterial evolution and supply-chain failures.

Two Bangladeshi programs show what works – and what doesn’t

icddr,b’s Matlab field site, a health and demographic surveillance system in rural Chandpur, reduced pneumonia deaths by roughly 40 percent over a decade through a combination of community-based oral antibiotics, pulse oximetry, and referral to a local hospital with oxygen. The program trained community health workers to identify hypoxemia using oximeters and to start oxygen therapy at home using portable concentrators.

BRAC, the country’s largest NGO, deployed a network of community health workers who deliver oral amoxicillin for suspected pneumonia. The program reached roughly 10 million children between 2015 and 2020, and contributed to the national mortality decline. But BRAC’s model stops at antibiotics. Workers do not carry oximeters or oxygen. Children who fail treatment are referred to public facilities, where oxygen may or may not be available.

Referral systems break down after dark. Most rural roads are unpaved, and few families have access to a vehicle. There is no national ambulance network for pediatric emergencies. A 2023 study in BMJ Global Health found that the median time from referral to arrival at a hospital with oxygen was 6 hours in rural Bangladesh, and 12 percent of referred children never arrived.

A telemedicine pilot in Rangpur, launched in 2022, connected community health workers to pediatricians via mobile phones. The program reduced referral delays by roughly 30 percent, but only covered about 50 villages. Scaling it nationally would require investment in mobile networks and training.

Another promising approach comes from the NGO Friendship, which operates floating health clinics in flood-prone areas of the north. These boats carry solar-powered concentrators and oximeters, serving communities that are cut off from roads for months. In a 2024 pilot, the clinics treated over 400 children with pneumonia, with a case fatality rate of under 3 percent—comparable to Dhaka’s best hospitals. But the boats cost roughly $50,000 each, and only six are in operation.

The controversy: Should Bangladesh invest more in oxygen or in prevention?

Among global health experts, a debate simmers. Some argue that prevention—vaccines, nutrition, handwashing—offers the best return on investment. The cost per life saved by PCV10 is estimated at roughly $1,500–3,000 in Bangladesh, according to Gavi. Oxygen therapy, by contrast, costs roughly $500–1,000 per life saved, depending on the setting.

Others counter that oxygen is the biggest preventable cause of death from pneumonia. “We have a cheap, effective intervention that we are not delivering,” said Dr. Shamim Ahmed, a health systems researcher at icddr,b. “The gap is not science. It is politics and logistics.” Donors have favored prevention because outcomes are easier to measure—vaccine coverage rates, for example—than oxygen availability, which requires tracking equipment maintenance and power supply.

The Ministry of Health’s budget reflects the tension. In fiscal year 2024–25, the allocation for the Expanded Program on Immunization was roughly $120 million, while the National Oxygen Plan received about $8 million. The imbalance is not unique to Bangladesh; it mirrors global patterns. WHO’s Oxygen for All initiative, launched in 2020, has struggled to gain traction, with only about $50 million pledged against a $1 billion target.

Reasonable people disagree on the right mix. But the evidence is clear: children in rural Bangladesh are dying because they cannot get oxygen. The controversy is not about whether oxygen works, but about how much society is willing to spend to deliver it.

A counterargument comes from some economists who argue that investing in oxygen infrastructure may be less cost-effective than strengthening primary care to prevent pneumonia in the first place. They point to a 2023 cost-effectiveness analysis in Health Policy and Planning that found integrated community case management (iCCM) for childhood illnesses—including pneumonia, diarrhea, and malaria—had a cost per death averted of roughly $2,000–4,000 in Bangladesh, higher than oxygen alone but with broader benefits. Yet iCCM also requires pulse oximetry and oxygen for severe cases, so the two strategies are complementary, not alternatives.

What other countries can learn from Bangladesh’s oxygen gap

Bangladesh is not alone. Nigeria, the Democratic Republic of the Congo, and India face similar oxygen deserts. In Nigeria, only about 30 percent of health facilities have functional oxygen, according to a 2023 WHO assessment. The DRC’s oxygen supply was overwhelmed during the COVID-19 pandemic and has not recovered.

Bangladesh’s National Oxygen Plan offers a template: assess needs, procure concentrators, train workers, and establish maintenance chains. But the plan’s slow implementation shows that templates are not enough. Sustainable supply chains—spare parts, consumables, technicians—matter more than devices. Solar-powered concentrators, tested in Cox’s Bazar for Rohingya refugee camps, have proven durable, but cost roughly $3,000 each, more than double the price of standard models.

Other countries can avoid Bangladesh’s mistakes. Investing in pulse oximetry and oxygen before vaccines reach full coverage could save more lives per dollar. Integrating oxygen into primary care, rather than relying on referral hospitals, reduces delays. And linking oxygen supply to renewable energy can insulate against power cuts.

India’s experience offers a cautionary tale. During the COVID-19 surge in 2021, oxygen shortages caused thousands of preventable deaths, even in cities. In response, the Indian government launched a national oxygen grid, but rural areas remain underserved. A 2024 study in BMJ Global Health found that only about 20 percent of rural health centers in India had functional oxygen, similar to Bangladesh’s figures.

Bangladesh’s success in cutting pneumonia deaths is real, but it is incomplete. The next phase of progress will require closing the oxygen gap, not just celebrating the vaccine win. The children in Sylhet and Sunamganj are waiting.
