Explore symptoms, assessment and rehabilitation considerations for respiratory.
Human metapneumovirus (HMPV) is a respiratory virus that can cause cold-like symptoms and, in some people, more serious breathing illness. It is not a newly discovered virus. The severity of symptoms and a person's health matter more than identifying the virus at home.
HMPV symptoms in adults and children
CDC HMPV information describes cough, fever, nasal congestion and shortness of breath. Illness can progress to bronchitis or pneumonia. Older adults, young children and people with weakened immunity can have more serious illness.
HMPV can also worsen existing airway conditions. Our asthma and COPD guide explains why symptoms and treatment plans differ. Follow your existing medical action plan and seek advice when breathing changes.
HMPV, flu and RSV cannot reliably be distinguished by symptoms
HMPV symptoms overlap with other respiratory infections. A clinician may use a respiratory sample to help identify the cause when it affects care decisions. Testing is not needed for every mild cold-like illness.
Tell the clinician about symptom severity, current medicines and any underlying condition. Do not delay medical care while trying to decide which virus caused a cough. An HMPV result also does not remove the need to investigate a person who is getting worse.
Treatment and home care
Current CDC guidance describes supportive care: there is no specific antiviral treatment or vaccine for HMPV. Rest, fluids and appropriate symptom relief may be enough for a mild illness, while severe illness can require hospital care. Follow existing fluid restrictions if your medical team has given them.
Ask a clinician or pharmacist which symptom-relief medicine is suitable, particularly for a child or someone taking other medicines. Avoid copying an adult medicine routine for a baby or child. Monitor breathing, drinking and whether the person is becoming more unwell.
A breathing-exercise programme does not treat the viral infection or replace assessment of worsening breathlessness. Follow medical advice before returning to exercise if the illness has affected breathing or your usual activity.
How HMPV spreads and how to reduce spread
WHO HMPV guidance explains spread through infectious respiratory particles, close contact and contaminated surfaces. HMPV has circulated for decades; its presence alone does not establish a new outbreak.
- Stay at home when ill and avoid close contact with people at greater risk.
- Improve ventilation where possible.
- Clean your hands and cover coughs and sneezes.
- Consider a mask in crowded or poorly ventilated spaces and when ill around others.
- Clean frequently touched surfaces and follow clinical advice for protecting vulnerable household members.
Respiratory infections can occur throughout the year. Seasonal patterns observed in one region do not establish the current level of HMPV in your area.
Symptoms needing urgent medical attention
NHS breathlessness advice recommends emergency care for severe breathing difficulty, inability to speak, blue or grey lips or sudden confusion.
NHS bronchiolitis guidance for babies and young children identifies breathing pauses, grunting or ribs pulling in, blue or grey colour, and being floppy or difficult to wake as emergency signs. These need care regardless of which virus is suspected.
Seek urgent advice for a child who is getting worse, feeding much less or showing dehydration. A baby under three months with a temperature of 38°C or higher needs urgent assessment. Adults with worsening breathlessness or difficulty maintaining hydration should also seek prompt medical advice.
Follow-up when symptoms continue
Persistent or worsening symptoms need medical review before being assigned an exercise routine. If an underlying lung condition limits activity, ask your treating team whether rehabilitation would help after the acute illness is assessed.
Our respiratory rehabilitation service can discuss that ongoing rehabilitation need alongside your medical plan. The home physiotherapy guide helps you prepare for a suitable follow-up consultation. Acute infection assessment and emergency care should not wait for an online rehabilitation appointment.
