In the United States alone, at least 821 children and young people aged 0 to 19 died from COVID-19 in the single year spanning August 2021 through July 2022, making the virus the leading infectious-disease killer in that age group and the eighth-leading cause of death overall for American children during that period. Globally, exact numbers are harder to pin down because surveillance systems vary enormously from country to country and because distinguishing deaths truly caused by COVID-19 from deaths that merely coincided with a positive test proved surprisingly difficult. The toll was far smaller than among adults, but the notion that children were immune to serious harm was never accurate.
The US Numbers and What They Mean
The most rigorous US estimate comes from a study that examined death certificates with COVID-19 listed as the underlying cause among people aged 0 to 19. In that one-year window, the 821 deaths translated to a crude death rate of 1.0 per 100,000 children. Broken down by age, infants under one year faced the steepest rate at 4.3 per 100,000, followed by teenagers aged 15 to 19 at 1.8 per 100,000. The school-age groups in between had somewhat lower rates, around 0.4 to 0.6 per 100,000. COVID-19 accounted for roughly 2% of all deaths among Americans under 20 during that period, but it ranked first among deaths from infectious or respiratory disease when compared against pre-pandemic 2019 figures.1JAMA Network Open. Assessment of COVID-19 as the Underlying Cause of Death Among Children and Young People Aged 0 to 19 Years in the US
Those numbers cover only one year and only one country. Cumulative US pediatric deaths across the entire pandemic were higher, and the global total higher still. But precise worldwide figures remain elusive because many low- and middle-income countries lacked the testing infrastructure to confirm pediatric COVID-19 deaths reliably. Research has shown that differences in pediatric COVID mortality between countries tracked closely with each country’s baseline neonatal mortality rate, suggesting that the quality of a nation’s healthcare system and its social conditions shaped pediatric death counts at least as much as the virus itself.2medRxiv. COVID-19 pediatric mortality rates are heterogeneous between countries
The Problem of Counting Deaths “From” Versus “With” COVID
One of the most persistent controversies around pediatric COVID deaths concerned whether the numbers were inflated. Early in the pandemic, the CDC’s data tracker drew from case reports submitted to local health departments. Any hospitalized patient who tested positive for SARS-CoV-2 generated a report, and if that patient died, the death was recorded in the tracker regardless of whether COVID was actually the cause. A child admitted for a head injury who happened to test positive, for instance, could be counted. The CDC’s own mortality-statistics chief acknowledged that this amounted to accidentally capturing deaths “with” rather than “from” COVID.3BMJ. Covid-19: US tracker overestimated deaths among children
Researchers studying pediatric deaths directly have echoed this concern. In descriptive studies, it is not always possible to determine whether a child died because of COVID-19 or died of another condition while carrying an active SARS-CoV-2 infection.4Pediatrics. Deaths in Children and Adolescents Associated With COVID-19 and MIS-C in the United States The JAMA Network Open analysis mentioned above tried to address this by limiting its count to death certificates where COVID-19 was listed as the underlying cause of death, a more conservative approach than simply tallying every death that occurred with a positive test. That distinction matters when you encounter different numbers from different agencies. Broadly, the death-certificate-based analyses produce lower, more defensible counts than the earlier surveillance trackers did.
Which Children Were Most Vulnerable
COVID-19 did not strike all children equally. Age mattered in a U-shaped way: infants had roughly double the odds of dying compared with children aged one to four, and those over ten also had increased mortality risk compared with the same reference group.5medRxiv. Which children and young people are at higher risk of severe disease and death after SARS-CoV-2 infection: a systematic review and individual patient meta-analysis The very youngest lacked mature immune defenses, while older adolescents’ physiology begins to resemble adults’, making them more susceptible to the inflammatory cascades that drive severe COVID.
Underlying health conditions were the strongest predictor of a bad outcome. Among children hospitalized for COVID-19 between 2022 and 2024, about 59% had at least one pre-existing condition. The most common varied by age. In infants, prematurity topped the list, followed by neurologic disorders and chronic lung disease. In children two years and older, the most prevalent conditions were neurologic disorders, asthma, chronic lung disease, obesity, and feeding-tube dependence.6Pediatrics. Hospitalization for COVID-19 and Risk Factors for Severe Disease Among Children: 2022–2024 A separate two-center cohort study found that every child who died of COVID-19 in their sample had an underlying chronic disease, compared with 57% of those who survived. These children had been in stable condition before catching the virus; their deaths resulted from COVID-19 itself, not from flare-ups of their pre-existing illnesses.7Archives of Medical Science. Risk factors of severe course and fatality in children hospitalized for COVID-19: a two-center cohort study
That finding cuts both ways. It means that COVID-19 was vanishingly unlikely to kill an otherwise healthy child, but it also means that children with chronic conditions, who were already medically fragile, faced a genuinely dangerous virus.
MIS-C as a Distinct Pathway to Death
Some pediatric deaths did not come from the acute infection at all. Multisystem inflammatory syndrome in children, or MIS-C, is a delayed inflammatory reaction that typically strikes two to six weeks after a SARS-CoV-2 infection, often one so mild the child never knew they had it. MIS-C can cause fever, rash, gastrointestinal symptoms, and dangerous inflammation of the heart and blood vessels.
Among nearly 2,800 US MIS-C cases reported between February 2020 and March 2021, 35 children died, a fatality rate of about 1.2%. Deaths disproportionately affected racial and ethnic minority children and were associated with being 16 to 20 years old or having pre-existing conditions.8PubMed Central. Demographic and Clinical Factors Associated With Death Among Persons <21 Years Old With Multisystem Inflammatory Syndrome in Children-United States, February 2020-March 2021 In lower-resource settings, MIS-C mortality was considerably worse. A multicenter study of critically ill MIS-C patients in middle-income countries reported a 9% death rate, compared with around 1.8% in high-income countries, with cardiovascular complications and extremely elevated ferritin levels found in all non-survivors.9PubMed Central. Mortality and clinical characteristics of multisystem inflammatory syndrome in children (MIS-C) associated with covid-19 in critically ill patients: an observational multicenter study (MISCO study)
MIS-C cases dropped dramatically once Omicron replaced Delta and once vaccination became available. But during the earlier pandemic waves, it was a genuinely frightening complication for families, and it added meaningfully to the pediatric death toll in a way that straightforward infection counts could miss.
How COVID Compared With Other Childhood Respiratory Infections
Context helps. Parents naturally want to know how dangerous COVID-19 was for children compared with more familiar threats like the flu or RSV. The answer depends on how you measure it. A large US study of more than 56,000 hospitalized children under five found that in-hospital mortality ran about 0.1% for RSV, 0.3% for COVID-19, and 0.4% for influenza. RSV, however, sent more children to the ICU (28% versus 22% for COVID) and required supplemental oxygen far more often (46% versus 20%).10PubMed Central. Clinical Outcomes in Children <5 Years of Age Hospitalized for Respiratory Syncytial Virus, COVID-19 or Influenza in the United States
Another study comparing all three viruses across both children and adults found that pediatric hospital admissions for COVID-19 were nearly ten times higher than for influenza during the study period, largely reflecting how much more transmissible SARS-CoV-2 was.11PubMed Central. COVID-19, Influenza, and RSV in Children and Adults: A Clinical Comparative Study of 12,000 Cases After adjusting for patient characteristics, in-hospital mortality and serious cardiac events showed no significant differences between the three viruses.12PubMed Central. Comparison of mortality and cardiovascular complications due to COVID-19, RSV, and influenza in hospitalized children and young adults In other words, COVID-19 was not dramatically more lethal per hospitalized child than flu or RSV, but it infected so many more children simultaneously that the absolute death count climbed higher.
Why Children Generally Fared Better Than Adults
The relatively low pediatric death rate was not luck. Children’s biology genuinely protects them from the worst of SARS-CoV-2 through several overlapping mechanisms. They tend to have lower baseline levels of the cell-surface receptor ACE2 that the virus uses to enter cells, and lower levels of the enzyme TMPRSS2 that helps the virus fuse with those cells. Their immune systems mount a more effective early interferon response, which helps contain the virus before it spreads widely in the body. They also carry fewer of the chronic conditions (hypertension, diabetes, obesity, cardiovascular disease) that amplify the dangerous inflammatory overreaction adults are prone to. Some researchers have pointed to an additional factor: children’s recent exposure to routine childhood vaccinations and common cold coronaviruses may prime a degree of cross-reactive immunity that older adults lack.13PubMed Central. The underlying mechanism behind the different outcomes of COVID-19 in children and adults
These protective factors explain why the vast majority of pediatric infections were mild or asymptomatic. They do not, however, make children invulnerable. Hundreds still died, and the virus found its way past these defenses in children with underlying conditions or in populations with limited access to healthcare.
How Variants and Vaccination Changed the Trajectory
Pediatric severity was not static. As the virus evolved and as vaccines rolled out, the picture shifted substantially. Data from Germany comparing different variant periods showed that the relative risk of COVID-related hospitalization and ICU admission in children dropped during the Delta wave compared with earlier strains, and then fell much further during Omicron. ICU admissions during the Omicron period were about 94% lower than during the Alpha period, and case fatality rates also decreased substantially, though children under five were an exception to the falling hospitalization trend.14PubMed Central. Comparing SARS-CoV-2 variants among children and adolescents in Germany: relative risk of COVID-19-related hospitalization, ICU admission and mortality
An international study covering more than 31,000 hospitalized children across multiple countries confirmed the pattern. ICU admissions dropped from about 13.5% of hospitalized pediatric patients in the earliest pandemic period to 5.5% in the Omicron era. The need for ventilatory support and oxygen therapy followed the same downward curve.15JAMA Pediatrics. International Pediatric COVID-19 Severity Over the Course of the Pandemic
Vaccination played a role in this decline alongside the shift to less virulent variants. A meta-analysis of mRNA vaccine studies in children aged five to eleven found that two doses cut the risk of hospitalization by about two-thirds and reduced the risk of MIS-C by roughly 95%.16PubMed Central. Assessment of Efficacy and Safety of mRNA COVID-19 Vaccines in Children Aged 5 to 11 Years: A Systematic Review and Meta-analysis Among adolescents in England, vaccination reduced COVID-related hospitalizations by about 40% after the first dose and about 40% more after the second, although these events were rare in absolute terms even among the unvaccinated.17PubMed Central. OpenSAFELY: Effectiveness of COVID-19 Vaccination in Children and Adolescents A Japanese cohort study found that vaccine-derived protection against severe infection was stronger and longer-lasting than protection against any infection, persisting well beyond the ten months at which protection against milder disease waned to near zero. Children who had both vaccination and a prior infection (hybrid immunity) had protection estimated at 83 to 97%.18PubMed. COVID-19 vaccine effectiveness and duration of protection among children and adolescents: A retrospective cohort study in 11 large cities in Japan
In Taiwan, researchers saw concrete evidence that updated clinical guidelines for pediatric COVID combined with expanded vaccination drove down disease severity, intubation rates, and ICU stays among children admitted to pediatric intensive care units during the Omicron wave.19Journal of the Formosan Medical Association. Clinical characteristics and outcomes of children with COVID-19 in pediatric intensive care units during the Omicron wave in Taiwan
Complications That Did Not Kill but Left a Mark
Death is the starkest outcome, but it was not the only one that worried pediatricians. Cardiovascular involvement was one of the more alarming complications in children who survived. A systematic review found that heart-rhythm abnormalities and left ventricular dysfunction were the most common cardiac consequences among children with COVID-19 or MIS-C, though no deaths from cardiovascular involvement were reported in previously healthy children in the studies reviewed.20PubMed Central. Cardiovascular Complications in Children Post COVID-19: A Systematic Review Echocardiographic studies found that pericardial effusion (fluid around the heart) occurred in about 23% of MIS-C patients, and various degrees of valve dysfunction were documented in both MIS-C and acute COVID groups.21PubMed Central. Echocardiographic assessment of cardiac involvement in pediatric COVID-19 patients: a cross-sectional study
The encouraging news is that most of these cardiovascular abnormalities resolved. A multicenter follow-up study found that cardiovascular problems associated with MIS-C were usually transient. However, in about 10% of cases, mild abnormalities were still detectable on imaging in the long term, without any clear connection to how severe the initial illness had been.22PubMed Central. Cardiovascular Involvement of Multisystem Inflammatory Syndrome in Children: A Multicentric Observational Study on Mid- and Long-term Follow-up with Cardiovascular Imaging
Neurological complications were rarer but sometimes severe. Case reports documented cerebrovascular events (strokes) in children with MIS-C, including one case of an eight-year-old girl who developed left-side paralysis during hospitalization for MIS-C that had followed an asymptomatic COVID-19 infection.23Srpski arhiv za celokupno lekarstvo. Severe neurological complications in a child with multisystem inflammatory syndrome in children after asymptomatic COVID-19 These events were uncommon, but they underscored that even children who seemed barely affected by the initial infection could face delayed and serious consequences.
The Indirect Toll on Children Who Did Not Get Sick
Perhaps the most underappreciated part of the pediatric COVID story is what happened not to children’s lungs but to their families. By May 2022, an estimated 10.5 million children worldwide had lost a parent or caregiver to COVID-19, and roughly 7.5 million had been orphaned (lost at least one parent). These estimates used the WHO’s relatively conservative excess-mortality figures; other modeling approaches suggested even higher numbers.24PubMed Central. Orphanhood and Caregiver Loss Among Children Based on New Global Excess COVID-19 Death Estimates An earlier modeling study covering just the first thirteen months of the pandemic, through April 2021, had already estimated that over 1.1 million children had experienced the death of a primary caregiver and 1.5 million had lost a primary or secondary caregiver.25PubMed Central. Global minimum estimates of children affected by COVID-19-associated orphanhood and deaths of caregivers: a modelling study
Losing a parent in childhood is one of the strongest predictors of poor outcomes in education, mental health, and economic stability later in life. These millions of newly orphaned children represent a slow-moving crisis whose effects will unfold over decades, long after the pandemic itself recedes from public attention. In this sense, the full cost of COVID-19 to children cannot be captured by counting pediatric deaths alone. The virus killed relatively few children directly, but it reshaped the lives of millions more by taking away the adults they depended on.
What Schools and Masking Policies Showed
School policies became one of the most heated debates of the pandemic, with parents and policymakers arguing over whether mask mandates and closures were justified given the relatively low pediatric death rate. The evidence on masking in schools is genuinely mixed. One widely cited early analysis suggested that US counties without school mask mandates had about 30 additional daily pediatric cases per 100,000 children compared with mandated counties. But a longer follow-up of the same data showed that this gap reversed within weeks: by the ninth week after schools reopened, counties without mandates actually had slightly lower case rates, and the difference was not statistically significant.26Journal of Infection. Lack of correlation between school mask mandates and paediatric COVID-19 cases in a large cohort
A separate retrospective study examining the community-wide effects of lifting school mask mandates found small, statistically significant increases in hospitalizations across all age groups in the weeks following the policy change, but no increase in deaths was identified among people aged 19 and under. The largest impacts on deaths were concentrated among adults over 70.27PubMed Central. Impact of lifting school mask mandates on community SARS-CoV-2 cases, hospitalizations, and deaths: a retrospective observational study In practical terms, school policies may have helped slow community transmission that ultimately harmed vulnerable adults more than children themselves. The debate about whether those policies were proportionate to the pediatric risk will likely continue for years, but the mortality data suggest the direct risk to children from school attendance was small.
