RSV is a common virus that causes cold-like symptoms in most people, but can lead to serious chest infections (bronchiolitis and pneumonia) in babies, older adults and those with weak lungs or immunity.
Most cases settle at home with fluids, rest and fever control
Saline nose drops and gentle suction for blocked noses in babies
Oxygen and hospital support for severe breathing difficulty
Protective antibody injections for high-risk infants in some settings
Good hand hygiene to prevent spread
When to see a doctor urgently
Fast, difficult or noisy breathing, or pauses in breathing
A baby feeding poorly or with fewer wet nappies
Bluish lips or skin, or grunting with each breath
High fever or symptoms getting worse rather than better

Frequently asked questions
Who is most at risk from RSV?
Premature and very young babies, older adults, and people with heart, lung or immune conditions are most likely to develop serious illness from RSV.
How is RSV different from a cold?
In most people RSV feels like a cold, but it more often spreads to the small airways and lungs in vulnerable groups, causing bronchiolitis or pneumonia.
Is there a vaccine for RSV?
Vaccines and protective antibody injections are available in some countries for older adults, pregnant women and high-risk infants. Ask your doctor what is available locally.
