In the shadow of a global pandemic, a study from Minia University in Egypt has surfaced a quiet but grave consequence for the youngest among us: children arriving at intensive care units not only burdened by COVID-19, but by a sudden and dangerous onset of diabetes. Between April and October of 2021, researchers observed that seven in ten children who tested positive for the virus were simultaneously experiencing diabetic ketoacidosis — a metabolic crisis that, left untreated, can claim a life.

COVID-19 linked to surge in severe diabetes cases in children, study finds
Children with severe diabetic ketoacidosis faced 10% mortality rate; 58% required intensive care admission; 63% experienced disease recurrence within 3 months.
Seven out of ten children with COVID-19 and new diabetes were in crisis

Why would a respiratory virus like COVID-19 trigger diabetes in children who had no signs of it before?
Mimi
The virus appears to activate the immune system in ways that make it attack the pancreas. In genetically susceptible kids, something about the infection—or the stress of the pandemic itself—tips the balance. The body starts destroying its own insulin-producing cells.
Mark
But 70 percent is a staggering number. Is that normal for children with COVID-19?
Mimi
No. This study found that rate specifically among children who had COVID-19 and newly diagnosed type 1 diabetes. It's the overlap that's unusual. The question is whether COVID-19 is causing the diabetes, or whether the pandemic disrupted care so badly that kids who would have been diagnosed anyway went undiagnosed until they crashed into ketoacidosis.
Mark
What does ketoacidosis actually do to a child's body?
Mimi
It's a cascade. Without insulin, blood sugar climbs dangerously high. The body breaks down fat for energy instead, producing acids that poison the blood. The child becomes confused, exhausted, can stop breathing properly. It's a medical emergency. A 10 percent mortality rate means one in ten of these kids didn't make it.
Mark
The study mentions 63 percent had disease recurrence within three months. Does that mean they weren't cured?
Mimi
It means the diabetes came back or never fully resolved. Type 1 diabetes is chronic—you don't cure it, you manage it. But the fact that it recurred so quickly in most of these children suggests their immune systems remained activated, still attacking the pancreas.
Mark
If this study isn't peer-reviewed yet, how confident should we be in these numbers?
Mimi
Cautiously. The data is real—61 children, documented cases, lab tests. But peer review will ask hard questions about whether the findings hold up, whether there are confounding factors, whether the same pattern appears in other countries. Right now it's a warning signal, not a proven fact.
The Pulse
- A 70% rate of diabetic ketoacidosis among COVID-19-positive children signals that the virus may be doing something far more insidious than causing respiratory illness — it may be dismantling the pancreas's ability to produce insulin.
- Nearly 58% of affected children required intensive care, and the mortality rate among those with both COVID-19 and ketoacidosis reached 10% — more than double the rate seen in children without the virus.
- Pandemic lockdowns likely delayed diagnoses, pushing children past the threshold of manageable illness into life-threatening crisis before families sought care.
- Three months after discharge, 63% of patients saw their diabetes symptoms return, suggesting the damage wrought — whether by the virus or by delayed treatment — was not easily undone.
- The study remains in preprint and has not yet been peer-reviewed, meaning its urgency is real but its conclusions must be held with scientific caution as the review process unfolds.
In the shadow of a global pandemic, a study from Minia University in Egypt has surfaced a quiet but grave consequence for the youngest among us: children arriving at intensive care units not only burdened by COVID-19, but by a sudden and dangerous onset of diabetes. Between April and October of 2021, researchers observed that seven in ten children who tested positive for the virus were simultaneously experiencing diabetic ketoacidosis — a metabolic crisis that, left untreated, can claim a life. The findings invite a deeper reckoning with how a virus reshapes not only the lungs, but the immune system's relationship with the body it was meant to protect.
Between April and October of 2021, pediatric intensive care units in Egypt began filling with children carrying a troubling dual burden: a new diagnosis of type 1 diabetes arriving alongside diabetic ketoacidosis, a condition in which the body's inability to produce insulin allows toxic acids to accumulate in the blood. Researchers at Minia University examined 61 such children, testing each for SARS-CoV-2 and analyzing their bloodwork for the markers of metabolic crisis. What they found was difficult to ignore — seven out of ten children who tested positive for COVID-19 were in ketoacidosis, and nearly two-thirds of those cases represented a first-ever diabetes diagnosis.
The severity of what these children faced was reflected in the numbers. Nearly 58% required intensive care unit admission, and the mortality rate among those with both COVID-19 and ketoacidosis reached 10%, compared to 4% among children with ketoacidosis but no viral infection. Three months after leaving the hospital, 63% experienced a return of their diabetes symptoms — a sign that recovery was incomplete and the underlying damage persistent.
Researchers offered several explanations for the surge. Pandemic restrictions likely kept families away from routine medical visits, allowing conditions to worsen undetected until they became critical. Beyond delayed access, the virus itself may be provoking the immune system to attack the insulin-producing cells of the pancreas in children who carry a genetic predisposition — a hypothesis supported by other studies linking COVID-19 to new-onset diabetes.
The study was posted as a preprint on Research Square while under review at BMC Pediatrics, meaning its findings are preliminary and not yet validated through peer review. Even so, the data poses a question that pediatricians and public health officials cannot easily set aside: as the virus continues to circulate, what systems must be built to identify and treat these children before the window for intervention closes?
Between April and October of 2021, researchers at Minia University in Egypt documented something troubling: a sharp rise in children arriving at pediatric intensive care units with a dangerous combination—newly diagnosed type 1 diabetes paired with diabetic ketoacidosis, a life-threatening metabolic crisis. The study, which examined 61 children admitted during this period, found that seven out of ten of those who tested positive for COVID-19 were experiencing ketoacidosis. For context, ketoacidosis occurs when the body cannot produce enough insulin to regulate blood sugar, causing acids to build up in the bloodstream to toxic levels. Without swift treatment, the condition can lead to unconsciousness, coma, and death.
The researchers tested all 61 children for SARS-CoV-2 infection and analyzed their blood work—measuring glucose levels, oxygen saturation, white blood cell counts, and the chemical markers that indicate ketoacidosis. What emerged from the data was stark: among the children who had both COVID-19 and type 1 diabetes, roughly 70 percent were in ketoacidosis. Of those in crisis, nearly two-thirds were experiencing diabetes for the first time. This matters because it suggests the virus itself, or the disruption it caused to medical care, may be triggering the immune system to attack the insulin-producing cells of the pancreas in children who carry genetic vulnerability to the disease.
The severity of these cases was reflected in hospital admissions. Nearly 58 percent of the children with ketoacidosis required intensive care unit placement. The mortality rate among this group—those with both COVID-19 and ketoacidosis—reached 10 percent, compared to 4 percent among children with diabetes and ketoacidosis but no COVID-19 infection. Three months after discharge, 63 percent of the patients experienced a return of their diabetes symptoms, suggesting the condition did not simply resolve with treatment.
Why the surge? The researchers point to several possibilities. During lockdowns and pandemic restrictions, families may have avoided routine medical visits out of fear of exposure to the virus, delaying diagnosis and treatment. Access to regular clinic appointments became harder. Some children may have gone undiagnosed until their condition became critical. There may also be psychological factors at play—the stress and disruption of the pandemic itself could influence immune function in susceptible children. The virus itself has been linked in other studies to new-onset diabetes, possibly by triggering autoimmune responses.
The study carries an important caveat: it has not yet been peer-reviewed. It was posted on the Research Square preprint server while under review at BMC Pediatrics, meaning the findings are preliminary and should not yet guide clinical practice. Still, the data raises an urgent question for pediatricians and public health officials: as COVID-19 continues to circulate, how many more children will present with this dangerous combination of new-onset diabetes and ketoacidosis? And what systems need to be in place to catch and treat them quickly? The 10 percent mortality rate among the most severely affected children suggests that speed and access to intensive care may be the difference between recovery and tragedy.
