Quick Answer: What Is hMPV?
Human metapneumovirus (hMPV) is a viral infection that mainly affects the upper respiratory tract but can spread to the lungs [1] [2]. It belongs to the same family as RSV and causes similar symptoms [1] [2]. Most people are exposed before the age of five [1] [3]. It usually resembles a common cold but can cause pneumonia and bronchiolitis in high-risk people [1] [3].
What the research says
hMPV is a major cause of lung infections in young children worldwide, and infants carry the highest risk. In a systematic review and modelling study of 119 published studies plus 40 unpublished ones, researchers estimated 14.2 million hMPV-associated acute lower respiratory infections, 643,000 hospital admissions, and 16,100 deaths (hospital and community) in children under 5 in 2018. About 58% of hospital admissions were in infants under 12 months, and 64% of in-hospital deaths occurred in infants under 6 months. (Wang et al., Lancet Glob Health, 2020 [4])
Most hMPV hospital stays in young children are short, but they add up. In a Scottish retrospective analysis of 1,462 laboratory-confirmed hMPV hospitalizations in children under 5 (2017 to 2023), about 10% of admissions needed a hospital stay of 5 days or more, while fewer than 1% required intensive care or ended in in-hospital death. RSV hospital incidence appeared substantially higher than hMPV hospital incidence in the same age group. (Kulkarni et al., Open Forum Infect Dis, 2026 [5])
In hospitalized children, hMPV can look a lot like RSV. In a surveillance study of 8,822 hospitalized children in Vietnam, 278 (3.2%) tested positive for hMPV. The proportions with clinical pneumonia and wheezing were similar to those in children with RSV and higher than in children with neither virus. (Otomaru et al., Sci Rep, 2023 [6])

What is human metapneumovirus (hMPV)?
Human Metapneumovirus (hMPV) is a significant contributor to respiratory illnesses worldwide. Discovered in 2001, it is now recognized as a leading cause of upper and lower respiratory tract infections, particularly in children. Researchers estimate that about 10% to 12% of respiratory illnesses in children are caused by hMPV [1].
While the virus is most famous for its impact on children, it can reinfect individuals throughout their lives [2] [3]. Subsequent infections are usually much milder than the initial one [1] due to the development of partial immunity. However, the virus remains a serious threat to the elderly and those with underlying lung conditions like asthma or COPD [1].
What are the symptoms and warning signs of hMPV?
The symptoms of hMPV often mirror those of the common cold or the flu, making it difficult to distinguish without medical testing.
Common Upper Respiratory Symptoms
Signs of Lower Respiratory Involvement
In more severe cases, the virus can move into the lungs, causing:
How does hMPV spread?
Human Metapneumovirus is highly contagious and spreads in ways similar to other respiratory viruses.
Transmission Method | Description |
Respiratory Droplets | |
Direct Contact | Shaking hands, hugging, or kissing someone who is infected [1]. |
Surface Contamination |
Who is at risk for severe hMPV illness?
Anyone can get hMPV, but young children, older adults, people with weakened immune systems and those with chronic lung conditions face a much higher risk of complications [1] [2].
Young Children: Especially premature infants and those under one year old [1] [4].
Older Adults: Individuals aged 65 and older often experience more severe symptoms [1] [3].
Immunocompromised: People with HIV, cancer [1], or those taking immunosuppressant medications.
Chronic Conditions: Those with pre-existing lung diseases like asthma or COPD are prone to severe flare-ups triggered by the virus [1] [3].
What complications can hMPV cause?
hMPV can lead to serious complications such as pneumonia, bronchiolitis, bronchitis and middle ear infections [1] [2] when it progresses beyond a simple cold.
Pneumonia: Infection and inflammation of the air sacs in the lungs.
Bronchiolitis: Inflammation of the small airways in the lungs, common in infants.
Bronchitis: Inflammation of the lining of the bronchial tubes.
Otitis Media: Middle ear infections, frequently seen in children following a viral respiratory illness.
How is hMPV diagnosed and tested?
A specific hMPV diagnosis is usually unnecessary in mild cases, but doctors may use swab tests, chest X-rays or bronchoscopy for hospitalized or high-risk patients [1] [3]. However, for hospitalized patients or those at high risk, doctors may use:
How is hMPV managed and treated?
hMPV has no specific cure or antiviral medicine, so treatment is supportive and focuses on comfort while the body fights the virus [1] [2]. Treatment is "supportive," meaning it focuses on keeping the patient comfortable while the body fights the virus.
At-Home Care for Mild Cases
Hospital Treatment for Severe Cases
If hospitalization is required, medical professionals may provide:
How can you prevent hMPV?
Since there is currently no vaccine for hMPV [2] [3], prevention relies on standard hygiene practices.
Hand Washing: Frequent washing with soap and water [1] [3] for at least 20 seconds [3].
Cough Etiquette: Covering your mouth and nose with a tissue or your elbow when coughing or sneezing [2].
Surface Disinfection: Regularly cleaning high-touch surfaces [2] [3] like toys and doorknobs.
Staying Home When Sick: Avoiding close contact with others who have respiratory symptoms [1].
Conclusion
Human Metapneumovirus is a nearly universal part of early childhood that continues to affect us throughout our lives. While usually manageable at home, its potential for severity in vulnerable populations makes awareness and early intervention critical. By practicing good hygiene and monitoring for severe symptoms, you can protect yourself and your family from the worst effects of this common virus. Seek emergency care right away for trouble breathing, very fast breathing, bluish lips or skin, signs of dehydration, or a baby who is unusually sleepy or hard to wake.
Frequently Asked Questions
Is hMPV the same as the flu?
No. While they share similar symptoms, they are caused by entirely different viruses. The flu (influenza) has a vaccine, while hMPV does not [2].
Can adults get hMPV?
Yes. While most common in children, adults can be reinfected throughout their lives, usually with milder symptoms [1] [2].
How long is the incubation period for hMPV?
It typically takes 3 to 6 days after exposure for symptoms to appear [3].
Is hMPV dangerous for pregnant women?
While not specifically linked to birth defects, any severe respiratory illness during pregnancy should be monitored closely by a doctor.
How long does hMPV stay on surfaces?
Like similar viruses, it can likely survive on hard surfaces for several hours.
Can you get hMPV twice?
Yes. Immunity is not permanent, though second infections are often less severe [1].
Does hMPV cause a rash?
It is not the most common symptom, but a mild skin rash can accompany the respiratory symptoms [1] [3], especially in children.
Is there a vaccine for hMPV?
Can antibiotics treat hMPV?
No. Antibiotics only kill bacteria. hMPV is a virus and will not respond to antibiotic treatment [1] [3].
When is hMPV season?
How is hMPV different from RSV?
They are very similar and both cause the most severe illness in infants [4]. RSV is generally more common and drives a higher hospital burden in young children [5].
Can hMPV cause asthma?
It doesn't cause asthma, but it is a very common trigger for asthma attacks in people who already have the condition [1] [2].
How long does the fever last?
A fever from hMPV usually lasts a few days, but if it persists longer than three days, you should contact a doctor [1].
Is hMPV contagious?
Can hMPV cause an ear infection?
Yes, it is a common complication, especially in young children [3]. Learn more about ear infections.
What does "metapneumovirus" mean?
It refers to the virus's scientific classification: the genus Metapneumovirus, within the Pneumoviridae family [2].
Can hMPV be fatal?
It is rarely fatal in healthy individuals, but it can be life-threatening for the very young, the very old, or the severely immunocompromised.
Should I stay home if I have hMPV?
Yes, you should stay home until you are fever-free and your symptoms are improving to avoid spreading the virus.
Does a humidifier help with hMPV?
A cool-mist humidifier can help soothe a sore throat and loosen congestion.
Can hMPV be detected in a standard flu test?
No. It requires a specific viral panel or PCR test to be identified.
Is hMPV more common than RSV?
Generally, RSV is more common, but hMPV is a significant and frequent cause of similar illnesses.
Can pets get hMPV?
No. Human Metapneumovirus is specific to humans and is not known to infect pets.
What is bronchiolitis?
It is the inflammation of the smallest air passages in the lungs, often caused by viruses like hMPV in infants. Read more in our bronchiolitis guide.
Can hMPV cause a "barking" cough?
While more common with croup, hMPV can sometimes cause a harsh, barking cough in children.
Is hMPV a new virus?
It was first identified by scientists in 2001 [2], but it has likely been circulating in the human population for decades [3].
How do I prevent my baby from getting hMPV?
Washing hands before handling the baby, avoiding sick people, and cleaning toys are the best preventive measures.
Can hMPV cause dehydration?
Yes, especially if a fever or sore throat makes a child reluctant to drink fluids.
Does hMPV affect the heart?
It primarily affects the respiratory system, but severe infections can put strain on the heart, especially in the elderly.
Can I use a nebulizer for hMPV?
A doctor may prescribe nebulized medications if the virus is causing significant wheezing or an asthma flare-up.
Is hMPV common in daycare settings?
Yes, like many respiratory viruses, it spreads quickly in environments where children are in close contact.
What is the difference between hMPV and a cold?
hMPV is one specific type of virus that causes cold symptoms, but it has a higher potential for lung complications than the average "cold" virus.
Can hMPV cause pneumonia in both lungs?
Yes, viral pneumonia can affect one or both lungs.
Is hMPV seasonal like the flu?
Yes, it follows a very predictable seasonal pattern, peaking in late winter.
Can hMPV be spread through food?
It is not a foodborne illness, but it could be spread if an infected person coughs on food or shares utensils.
Does honey help a cough from hMPV?
For children over one year old, a spoonful of honey can help soothe a viral cough.
Can hMPV cause a sore throat?
Yes, a sore throat is a very common early symptom of the infection.
How long are you contagious with hMPV?
You are usually most contagious for the first few days of symptoms, but children may shed the virus for longer.
Can hMPV cause sinus infections?
Yes, it can lead to secondary bacterial sinus infections in some cases.
What is PCR testing?
Polymerase Chain Reaction (PCR) is a highly sensitive lab technique used to detect the genetic material of the virus.
Does hMPV cause shortness of breath?
Yes, if the infection spreads to the lower respiratory tract, it can make breathing difficult.
Can hMPV be treated with steroids?
Doctors may use corticosteroids in severe cases to reduce inflammation in the airways [1].
Is hMPV dangerous for people with COPD?
Yes, it is a frequent cause of COPD exacerbations (flare-ups) [1] [2] that can lead to hospitalization.
Can hMPV cause wheezing in adults?
Yes, particularly in those with underlying lung conditions or severe infections.
Does vitamin C prevent hMPV?
There is no evidence that vitamin C prevents hMPV infection, though a healthy immune system is always beneficial.
Can hMPV be spread by kissing?
Yes, direct contact with respiratory secretions is a primary way the virus spreads [1].
What is the "peak age" for severe hMPV?
While it affects all ages, infants under 12 months have the highest risk of severe illness, and in-hospital deaths in young children are concentrated in infants under 6 months [4].
Can hMPV cause a high fever?
Yes, fevers over 102°F are possible, especially in young children.
Does hMPV cause body aches?
Like many viral infections, it can cause general malaise and mild body aches.
Is hMPV a type of coronavirus?
No. It belongs to the Pneumoviridae family (the same family as RSV) [2], which is different from the Coronaviridae family that includes the coronavirus behind COVID-19.
Where can I get tested for hMPV?
Most urgent care centers and hospitals can perform viral respiratory panels that include hMPV.
