Symptoms and Care
Symptoms of RSV infection usually include
- Runny nose
- Decrease in appetite
These symptoms usually appear in stages and not all at once. In very young infants with RSV, the only symptoms may be irritability, decreased activity, and breathing difficulties.
RSV can also cause more severe infections such as bronchiolitis, an inflammation of the small airways in the lung, and pneumonia, an infection of the lungs. It is the most common cause of bronchiolitis and pneumonia in children younger than 1 year of age.
Almost all children will have had an RSV infection by their second birthday. People infected with RSV usually show symptoms within 4 to 6 days after getting infected.
Most RSV infections go away on their own in a week or two. You can manage fever and pain with over-the-counter fever reducers and pain relievers, such as acetaminophen or ibuprofen. Talk to your healthcare provider before giving your child nonprescription cold medicines, since some medicines contain ingredients that are not recommended for children. It is important for people with RSV infection to drink enough fluids to prevent dehydration (loss of body fluids).
Healthy infants and adults infected with RSV do not usually need to be hospitalized. But some people with RSV infection, especially infants younger than 6 months of age and older adults, may need to be hospitalized if they are having trouble breathing or are dehydrated. In most of these cases, hospitalization only lasts a few days.
Visits to a healthcare provider for an RSV infection are very common. During such visits, the healthcare provider will evaluate how severe the person’s RSV infection is to determine if the patient should be hospitalized. In the most severe cases, a person may require additional oxygen or intubation (have a breathing tube inserted through the mouth and down to the airway) with mechanical ventilation (a machine to help a person breathe).
There is no specific treatment for RSV infection, though researchers are working to develop vaccines and antivirals (medicines that fight viruses).
