How Many People Die From Pneumonia Every Day
Pneumonia and other lung infections kill around 7,100 people a day, mostly toddlers and the over-70s. The full breakdown by age, country, cause and trend.
Picture two hospital beds, thousands of miles apart, on the same winter night. In one, on a children's ward in northern India, a 14-month-old boy is breathing so fast that his ribs pull inward with every breath. His mother brought him in after three days of cough and fever. In the other, in a care home in the north of England, an 88-year-old woman has stopped eating and become confused. Her family assumed she was just tired. Her chest X-ray shows a shadow across the lower part of her right lung.
They are separated by eight decades and two continents, but they have the same illness. Pneumonia is the great infectious killer of both ends of life. It takes the very young before their immune systems are ready and the very old once their immune systems have started to fade.
The headline number
Lower respiratory infections, the group of illnesses dominated by pneumonia, kill about 2.6 million people per year according to the World Health Organization's Global Health Estimates. That works out to roughly 7,100 deaths every day, or about five deaths every minute. It makes lung infection the deadliest infectious disease on earth, and one of the leading causes of death overall.
Those deaths are part of the roughly 62 million people who die each year, which you can watch happening second by second on our live death counter.
| Time period | Pneumonia and lower respiratory infection deaths (approx.) |
|---|---|
| Per second | 0.08 |
| Per minute | 4.9 |
| Per hour | 300 |
| Per day | 7,100 |
| Per week | 50,000 |
| Per month | 217,000 |
| Per year | 2,600,000 |
Different research groups use slightly different methods. The Global Burden of Disease study at the University of Washington puts the most recent figure a little lower, at around 2.2 million, partly because it counts COVID-19 separately. Either way, lung infections kill more people every year than tuberculosis, HIV and malaria combined. You can see where they sit among all the big causes on our lower respiratory infections page.
What pneumonia actually is
Pneumonia is an infection of the lungs that fills the tiny air sacs, the alveoli, with fluid and pus. Healthy alveoli fill with air every time you breathe in, and oxygen passes from them into the blood. When they fill with fluid instead, breathing becomes painful and oxygen levels in the blood fall.
The term "lower respiratory infection" covers pneumonia plus bronchiolitis and serious bronchitis. In practice, pneumonia does most of the killing.
| Main cause | Who it affects most | Notes |
|---|---|---|
| Streptococcus pneumoniae (pneumococcus) | All ages, especially young children and older adults | The single deadliest cause of pneumonia worldwide |
| Respiratory syncytial virus (RSV) | Babies under 6 months, frail older adults | About 100,000 deaths a year in children under 5 |
| Influenza | Older adults, people with chronic illness | Often leads to bacterial pneumonia |
| Haemophilus influenzae type b (Hib) | Young children | Largely controlled where vaccination is routine |
| Staphylococcus aureus | All ages | Often follows flu; can be drug resistant |
| COVID-19 | Older adults | Counted separately in most global estimates |
| Aspiration (food or saliva entering the lungs) | Frail elderly, people after stroke | A common final illness in old age |
The RSV estimate comes from a large analysis published in The Lancet in 2022, which found that roughly half of those child deaths happen in babies under six months old. The flu link is important too, and we explore it in how many people die from the flu every year.
Who pneumonia kills: the two ends of life
Pneumonia deaths do not fall evenly across the population. They pile up at the very start of life and again at the end.
| Age group | Approx. share of lower respiratory infection deaths |
|---|---|
| Under 5 | ~27% |
| 5 to 49 | ~10% |
| 50 to 69 | ~18% |
| 70 and over | ~45% |
These shares are rounded from Global Burden of Disease estimates. Their story is clear. In rich countries, pneumonia is overwhelmingly a disease of old age. In poor countries, it remains one of the biggest killers of small children.
Children
UNICEF estimates that pneumonia kills more than 700,000 children under five every year, around 2,000 a day. That is roughly one child every 43 seconds, and it makes pneumonia the leading infectious cause of death in young children worldwide. Many of those children are newborns, which links pneumonia closely to the story told in how many newborn babies die every day.
The risk factors are the same ones that drive almost all child deaths in poor countries.
| Risk factor for child pneumonia | Why it matters |
|---|---|
| Malnutrition and wasting | A starved immune system cannot fight infection |
| Household air pollution | Smoke from cooking fires damages small lungs |
| Not being exclusively breastfed | Breast milk passes on protective antibodies |
| Missing vaccines | Pneumococcal, Hib, measles and whooping cough jabs all prevent pneumonia |
| Crowded housing | Infections spread quickly between family members |
| Living far from a clinic | Treatment is delayed until the child is critically ill |
Household air pollution deserves special mention. The World Health Organization links cooking smoke to more than 3 million deaths a year, including over 200,000 children under five, many of them from pneumonia. We cover that hidden killer in how many people die from air pollution every day and on our air pollution page.
Older adults
At the other end of life, pneumonia is often the final event rather than the whole story. An 85-year-old with heart failure, dementia or a recent stroke is far more likely to develop pneumonia, and far less likely to survive it. Doctors used to call pneumonia "the old man's friend", because it often brought a relatively quick and peaceful end to a long final illness.
In older people, pneumonia does not always look like pneumonia. There may be no high fever and no dramatic cough. The first signs are often confusion, falls, loss of appetite or simply not being themselves. That is one reason it is so often caught late. It is also why pneumonia deaths rise so sharply in winter, a pattern we explore in why winter kills more people than summer. Our 85 and over age group page shows how infections and frailty shape mortality in the oldest age band.
Where pneumonia kills
The child deaths are highly concentrated. Save the Children and UNICEF have estimated that around half of all child pneumonia deaths happen in just five countries.
| Country | Why the toll is high |
|---|---|
| Nigeria | Large child population, low vaccine coverage, high malnutrition |
| India | Huge population; burden falling fast but still large |
| Pakistan | Household air pollution, limited oxygen in clinics |
| DR Congo | Conflict, weak health system, very high child mortality |
| Ethiopia | Rural distances to care, malnutrition |
Among adults, the pattern is different. Countries with the oldest populations, such as Japan, the UK and much of Europe, have large numbers of pneumonia deaths simply because so many people live into their late 80s and 90s. In Japan, pneumonia and aspiration pneumonia together rank among the top causes of death. In the United States, the CDC lists influenza and pneumonia together among the leading causes, with roughly 40,000 to 50,000 deaths a year in recent years.
Why it can be stopped
Here is what makes the child death toll so hard to accept. Most pneumonia is preventable, and most bacterial pneumonia is treatable with cheap antibiotics.
A course of amoxicillin for a child with pneumonia costs well under a dollar. A child with severe pneumonia may also need oxygen, which is far harder to provide in a clinic without reliable electricity. Before the COVID-19 pandemic, a lack of medical oxygen was one of the most neglected problems in global health. The pandemic exposed it, and investment in oxygen supply has grown since.
| Intervention | What it does |
|---|---|
| Pneumococcal conjugate vaccine (PCV) | Protects against the deadliest bacterial cause |
| Hib vaccine | Has nearly eliminated Hib pneumonia where it is used |
| Measles vaccine | Measles often kills through pneumonia |
| RSV protection for infants | New antibody shots and maternal vaccines protect babies in their first months |
| Flu vaccine for older adults | Reduces flu and the bacterial pneumonia that follows it |
| Clean cookstoves | Cut exposure to household smoke |
| Amoxicillin | Cures most bacterial pneumonia in children |
| Pulse oximeters and oxygen | Spot and treat low oxygen before it kills |
Measles is a particularly important link. Many of the children who die "of measles" actually die of pneumonia that follows it, which is why falling measles vaccination is so dangerous. We cover that in how many people die from measles every year.
The trend: falling for children, rising for the old
Global deaths of children from pneumonia have fallen by more than half since 2000, thanks to vaccines, better nutrition, cleaner fuels and wider access to antibiotics. That is real progress, and it is a big part of why overall child mortality has fallen so far.
At the same time, the number of older adults dying of pneumonia has been creeping up, simply because the world is ageing. More people living into their 80s and 90s means more people vulnerable to lung infections at the end of life.
| Group | Trend since 2000 | Main driver |
|---|---|---|
| Children under 5 | Falling steeply | Vaccines, nutrition, treatment |
| Working-age adults | Falling slowly | Better health care, HIV treatment |
| Adults over 70 | Rising in total numbers | Population ageing |
There is also a growing threat in the background. Antibiotic resistance is making some bacterial pneumonias harder to treat. Lung infections are among the biggest contributors to deaths linked to drug-resistant bacteria, and many of those deaths end in sepsis, when infection spreads through the body.
How pneumonia compares
| Cause | Approx. deaths per day |
|---|---|
| Cardiovascular disease | ~51,000 |
| Cancer | ~27,400 |
| Chronic respiratory disease (mostly COPD) | ~10,700 |
| Pneumonia and lower respiratory infections | ~7,100 |
| Diabetes | ~5,500 |
| Tuberculosis | ~3,400 |
Lung infections are the fourth biggest line on that table and the only infectious one in the top tier. You can compare them directly with any other cause using our compare causes tool.
Warning signs worth knowing
Pneumonia is not always obvious, especially in babies and older people. The World Health Organization teaches health workers to look for fast breathing and the chest pulling in below the ribs as the key signs in young children. In adults, warning signs include:
- A cough with fever that gets worse instead of better
- Shortness of breath at rest
- Sharp chest pain when breathing in
- Confusion or drowsiness, especially in older people
- Blue or grey lips
- A fast heart rate
Anyone with these signs, particularly a baby, a frail older person or someone with a long-term illness, should get medical help quickly.
Every year on 12 November, World Pneumonia Day highlights the children still dying of a disease that a dollar's worth of medicine and a vaccine could prevent.
While you were reading this
You have spent about 12 minutes with this article. In that time, roughly 59 people have died of pneumonia or another lung infection. Around 16 of them were children under five. Most of the rest were older adults, many of them in their 80s and 90s, for whom a chest infection was the last thing a tired body could not overcome.
You can see those deaths inside the full picture of global mortality on our live death counter and on the deaths today page. If you want to see how your own risk profile looks, try the risk calculator.
Pneumonia will always be with us, because some lung infections at the end of a long life are a natural part of dying. But the 2,000 children a day are not. They are dying of a disease we have known how to prevent and treat for decades, and every one of those deaths is a sign of a vaccine, a course of antibiotics or a cylinder of oxygen that did not arrive in time.
