RSV in Kids

· ·

Contributor Dr. Elise Herman

We are definitely in the sick season and Respiratory Syncytial Virus (RSV), a common fall/wintertime virus, is very prevalent right now. Most kids have had RSV at least once by age 2 years and usually it just causes a mild cold. In some children, especially preemies, young infants, and those with heart, lung, or immune system problems, RSV can be more serious. It can cause pneumonia (lung infection) and bronchiolitis (inflammation of the small airways). Adults also get RSV, though as with most kids, they usually just have mild cold symptoms. Elderly adults or those with compromised immune systems or underlying health problems can develop more severe RSV.

RSV spreads by direct contact with the virus by kissing, sharing drinks, or touching a contaminated surface). Airborne droplets from a cough or sneeze are also infectious. People are contagious for a day or two before signs of illness and then for 3-8 days after becoming sick.

RSV symptoms include runny nose, cough, sneezing, fever, and decreased appetite. There may be mild wheezing, which is a high-pitched musical sound heard with breathing out. RSV typically lasts 1-2 weeks.

If RSV is more severe, there may be signs of difficulty breathing such as rapid breathing and sucking or pulling in between the ribs or just below the neck (“retractions”). Other warning signs include grunting respirations, and the lips or tongue appearing pale or bluish. Trouble breast or bottle feeding and pauses in breathing are worrisome signs sometimes seen in young infants.

Testing for RSV (done with a nasal swab) is not needed if your child is mildly affected. If the illness seems more severe, RSV testing may be ordered.  Kids can test positive for RSV for days to weeks, even once they appear recovered. There is no need to do testing to see if a child is “over” their infection.

There is no cure for RSV and most kids just need basic at-home care. Ensuring your child gets enough fluids is important. Small frequent feedings may be better tolerated and using saltwater nasal drops and suctioning prior to infant feedings can help. Breast milk can be expressed and put in a cup or bottle if feeding at the breast is too difficult.

Tylenol (over 2 months) or Advil (over 6 months) for discomfort is fine, but do not worry about “getting a fever down”, as the fever may be helping your child fight the infection. Severely ill kids may need oxygen and IV fluids in the hospital to treat dehydration, but this is uncommon and usually is just for a few days. Only 1-2% of infants under 6 months of age need to be hospitalized with RSV.

To decrease the risk of kids and adults getting and spreading RSV, practice good handwashing with soap for 20 seconds. Teach your child to cover coughs and sneezes with tissue or their elbow. Avoid sharing drinks and utensils.  If your child is at high risk of severe RSV, you may want to avoid childcare and crowded settings if RSV activity is high. Masks in kids over age 2 years are effective at decreasing spread of the virus. Avoid smoke exposure which is harmful to lungs in general.

There is no vaccine for RSV yet, though some are in the works. If your child is 6 months or older, it is vital to vaccinate them against influenza and COVID-19 since these can make RSV more serious. There is an injected monoclonal antibody medication to prevent severe RSV only in very high-risk kids.

Remember that most kids with RSV will have a mild illness. You should call your child’s provider, however, if there are signs of dehydration (not drinking well, poor urination, or looking pale or weak), extreme fatigue, or difficulty breathing.

Respiratory Virus Season and Children

· ·

As cooler weather approaches, the “sick” season does, too. For kids, this usually means respiratory illnesses, ranging from cold to croup or pneumonia. While these sicknesses are usually mild, more severe cases are rapidly increasing, with more kids going to the ER and being hospitalized. The viruses responsible include Respiratory Syncytial Virus (RSV), rhinovirus, adenovirus, and enterovirus. To complicate things, influenza season typically starts in October, and with COVID-19 currently spiking in Europe, a surge is predicted to hit the US soon.

Children are walking in nature, fall leaves.

This earlier and more severe start to the respiratory season for kids is felt to be related to gathering again (without masks) in schools and social settings. Kids do not have much immunity from last year when the respiratory season was milder due to social distancing and other anti-COVID measures. Wildfire smoke exposure may also be a contributing factor.

Most kids who contract these viruses will get a simple cold (“upper respiratory infection”), nasal congestion, mild cough, and mild fatigue. A low-grade fever is common for the first three days of illness. Kids may be sick for 1-2 weeks but remain fairly active with good fluid intake though overall eating is often decreased.

Younger or premature infants and children with lung problems like asthma are at increased risk of more severe illnesses like pneumonia. General warning signs include the pale or dusky color of the lips or skin, and increased work of breathing—rapid breathing with the ribs showing on inspiration (“retractions”). Unusually noisy breathing, such as wheezing (high-pitched musical noise with breathing out) or stridor (crowing noise with breathing in), is concerning. An infant who cannot feed well from a breast or bottle is worrisome. Extreme lethargy or limb weakness at any age is very concerning.

For mild respiratory illnesses, the diagnosis is usually based on symptoms and examination alone. Checking respiratory rate, heart rate, and oxygen level are routine when the child is seen by a medical provider. Testing for viruses with a ‘respiratory panel’ can be done but is expensive and usually reserved for those more severely ill since there are few specific anti-viral treatments available. Specific testing for COVID-19 and RSV may be done, given that the implications of having these viruses are more significant regarding attending school, childcare, etc.

If your child has typical cold symptoms, it is essential to ensure they stay well-hydrated; solid food intake is less important. Offer infants extra breast milk or formula. Saltwater nose drops and nasal suction for infants can be helpful in terms of clearing mucous which interferes with breathing through the nose. Fever control with Tylenol (over age two months, though talk to a provider first) or Advil (over age six months) is primarily for comfort since fever, as part of the immune response, may help fight the virus.

No cold medications are recommended under the age of four years and should be used with caution for those 4-6 years old. These meds are usually not helpful and may have harmful side effects in younger kids. Honey (1/2 to 1 tsp by mouth) may help to cough but is safe only for those over one year of age.

To help prevent respiratory illnesses, keep up the frequent handwashing we have all gotten good at during the pandemic. In addition, kids should be reminded not to touch their faces and not to share food or drinks. Although not easy, masking (especially if your child will be in a large group) does help prevent illness. Lastly, it is vital to get your child vaccinated against those respiratory viruses for which we have safe, effective vaccines—COVID-19 and influenza.
