Respiratory Syncytial Virus (RSV) is best known for causing cold-like symptoms, especially in young children. However, many parents and adults are surprised when vomiting occurs alongside respiratory symptoms. This often leads to an important question: Does RSV cause vomiting? While vomiting is not the most common symptom of RSV, it can occur in certain cases, particularly in infants, young children, and individuals with more severe infections. Understanding how RSV affects the body and when vomiting may be a concern can help you know when to seek medical care.

How RSV Affects the Body
RSV primarily infects the respiratory tract, affecting the nose, throat, and lungs. It spreads easily through respiratory droplets and direct contact with contaminated surfaces. Symptoms typically begin mild and may worsen over several days.
Common RSV symptoms include:
- Runny or stuffy nose
- Cough
- Fever
- Wheezing or rapid breathing
- Decreased appetite
While these symptoms are mainly respiratory, RSV can also impact feeding and digestion, especially in young children.
Why Vomiting Can Occur With RSV
Vomiting associated with RSV is usually not caused by a stomach infection. Instead, it often occurs as a secondary effect of the illness. Frequent coughing can trigger a gag reflex, leading to vomiting, particularly in infants and toddlers. Swallowing mucus from heavy congestion can also irritate the stomach and cause nausea or vomiting. Fever and dehydration may further contribute to stomach upset. In infants, reduced feeding combined with mucus buildup can make vomiting more likely during RSV infections.
Who is Most Likely to Experience Vomiting With RSV?
Vomiting is more commonly seen in:
- Infants and young children
- Children with severe cough or congestion
- Individuals with sensitive gag reflexes
- Patients with more intense RSV symptoms
Adults with RSV may experience nausea, but vomiting is less common unless symptoms are more severe or accompanied by dehydration.
Managing Nausea and Vomiting During an RSV Infection
If vomiting is mild and infrequent, supportive care at home may help:
- Offer small, frequent sips of fluids to prevent dehydration
- Clear nasal congestion before feeding in infants
- Keep the head elevated when resting
- Monitor urine output and hydration status
Avoid forcing large meals until vomiting improves, and focus on maintaining hydration.
When to Seek Urgent Care
Vomiting can become concerning if it leads to dehydration or worsens respiratory symptoms. Visit an urgent care center if you or your child experiences:
- Persistent or frequent vomiting
- Signs of dehydration, such as dry mouth or reduced urine output
- Difficulty breathing or worsening cough
- High or persistent fever
- Lethargy or inability to keep fluids down
Urgent care providers can assess symptoms, check oxygen levels, and determine whether further treatment or monitoring is needed.
