Respiratory Syncytial Virus (RSV) is a common virus that primarily affects the lungs and airways. This highly contagious virus can cause infections in people of all ages, though it is often more severe in infants and older adults. While RSV is recognized for its respiratory effects, it can lead to vomiting in some individuals.
Understanding Common RSV Symptoms
RSV typically presents with symptoms similar to a common cold, usually appearing four to six days after exposure to the virus. Common indicators include a runny or congested nose, sneezing, and a cough. Many individuals may also experience a low-grade fever and wheezing, which is a high-pitched sound during breathing.
Why Vomiting Can Occur with RSV
Vomiting can occur with RSV, though it is often an indirect result of the illness rather than a primary gastrointestinal infection. One reason is severe or persistent coughing, which can trigger the gag reflex and lead to vomiting. Excessive mucus production, common with RSV, may also be swallowed, irritating the stomach and causing vomiting. This is particularly relevant for infants and young children who may not effectively clear their nasal passages and throats.
The body’s response to a viral illness can also contribute to vomiting. General malaise, decreased appetite, and dehydration can all upset the digestive system.
Recognizing When RSV Symptoms Are Serious
Certain symptoms indicate a more severe RSV infection that requires prompt medical attention. Signs of breathing difficulty include rapid, shallow breathing, flaring nostrils, or the skin pulling inward between or under the ribs with each breath. A bluish tint to the skin, particularly around the mouth or fingernails, signals a lack of oxygen. Dehydration is another serious concern. Signs of dehydration can include a decrease in wet diapers for infants, poor feeding, or unusual lethargy and irritability. A high fever that does not respond to medication, or a fever in very young infants, also warrants medical evaluation.
Caring for Someone with RSV at Home
Most RSV infections are mild and can be managed at home with supportive care. Adequate fluid intake is important to prevent dehydration; offer small, frequent sips of fluids like water, broth, or electrolyte solutions, and for infants, continue with breast milk or formula. Fever and discomfort can be managed with over-the-counter medications such as acetaminophen or ibuprofen, as appropriate for age. Never give aspirin to children due to the risk of Reye’s syndrome. Clearing nasal passages using saline drops and a nasal aspirator, particularly for babies, can help ease congestion, and a cool-mist humidifier can moisten the air.
