Respiratory Syncytial Virus (RSV): What Parents Need to Know
A triple epidemic is upon us. Occurring all at the same time and earlier than in past years, the flu and respiratory syncytial virus (RSV) have joined forces with COVID-19 to create new layers of stress for parents and families in our region and across the country. These respiratory viral infections have also stretched the capacities of emergency rooms, resulting in shortages of hospital beds and staff alike.听
Most of us are familiar with the flu鈥攁 disease whose symptoms can range from mild to severe, depending on the viral strain that comes along in any particular year. And even though COVID-19 is still a new disease for humans, we have been learning to deal with it and live with it for nearly 3 years. But for many of us, RSV is much less familiar.听
So, let鈥檚 get familiar with it. That鈥檚 the best way to keep our children safe from a common infection that can occasionally turn dangerous, especially in newborns and infants less than 2 months old.听
What is RSV?听
RSV is a common respiratory virus that usually causes mild, cold-like symptoms, but in a small number of children, it can develop into bronchiolitis or even pneumonia. Unlike COVID-19 and the flu, there is no vaccine for RSV just yet, but one may well become available in 2023.听听
Why has RSV come back with a vengeance this year?听
Because of masking and social distancing to contain the spread of COVID-19, there were far fewer cases of RSV in 2020 than usual. However, the arrival of COVID vaccines in early 2021 led some people to discontinue these anti-COVID measures鈥攅specially wearing masks. Predictably, RSV cases began to rise in the spring of 2021. RSV and the flu also started earlier than usual this year.听听
What are the main symptoms of RSV?听听
An RSV infection usually comes with the following symptoms:听
- Runny nose听
- Decrease in appetite听
- Coughing听
- Sneezing听
- Fever听
According to the (CDC), these symptoms usually appear in stages鈥攏ot all at once. In very young infants, the only symptoms may be irritability, decreased activity and breathing difficulties.听
In a small number of infants, RSV can turn from mild to more serious, morphing from an upper respiratory tract infection to a lower one: bronchiolitis, an infection of the bronchioles (the smallest passageways leading to the airways in the lungs), or, rarely, pneumonia.听
Flu, COVID and RSV have the potential to lead to an infection of the lower respiratory tract, such as bronchiolitis or pneumonia. Infants under 6 months old are especially vulnerable to having more severe infections.听
鈥淎lmost all children will have had an RSV infection by their second birthday,鈥 says Dr. Chloe Rowe, Assistant Professor of Clinical Pediatrics at Weill Cornell Medical College and Assistant Attending Pediatrician at NewYork-Presbyterian Hospital. 鈥淥nly 1 to 2 percent of babies younger than 6 months with an RSV infection will require a hospital stay. Most of them can go home after 2 or 3 days. Rarely, a child may need care in a pediatric intensive care unit (PICU).鈥听
Which children are at greatest risk for serious illness?听
- Infants 12 weeks old or younger at the start of RSV season听
- Premature or low birth weight infants (especially those born before 29 weeks of gestation)听
- Infants with chronic lung disease听
- Babies with certain types of heart defects听
- Those with weak immune systems due to illness or treatments听
What are the best ways for parents to take care of their children at home?听
Although specific treatments for RSV are not on offer, parents can manage their children鈥檚 symptoms as follows, per the recommendations of 麻豆高清鈥檚 pediatricians:听
- Relieve congestion听
- Use steam from a warm shower, cool-mist humidifier or nasal saline drops or spray听
- Limit your use of suctioning to instances where nasal congestion is interfering with feedings, as overzealous use can irritate the nasal passages and lead to worsening mucus accumulation.听
- Use homeopathic remedies听
- Over-the-counter cough and cold medications are not recommended for children under 4 to 6, but there are homeopathic remedies that may help. Medications such as Zarbees and Hyland鈥檚 can help relieve symptoms with all-natural ingredients.听听听
- Note: Honey and products containing honey should not be given to infants under 12 months old.听
- Use antipyretics (children鈥檚 acetaminophen or ibuprofen)听
- Give acetaminophen (Tylenol) to children over 2 months old or ibuprofen (Motrin or Advil) to children over 6 months old as needed for fever or discomfort. In children over 6 months, you can alternate between these two medications, making sure there are no fewer than 4 hours between Tylenol doses and no more than 5 doses in a 24-hour period. Allow no fewer than 6 hours between Advil/Motrin doses.
- Keep your child hydrated
- For infants, breast milk or formula are the best forms of hydration as they also provide nutrition. For toddlers and older children, you can offer water, diluted juice or Pedialyte. Bland foods like broth and oatmeal may be helpful, but focus on ensuring that your child is drinking well rather than consuming solid foods.
When should you seek medical care?听听
RSV symptoms typically peak on days 3 through 5 after infection. Fortunately, almost all children recover from an RSV infection on their own.听
However, call your pediatrician right away if your child exhibits any of the following:听
- Persistent fever for more than 48 to 72 hours, including fevers that return after Tylenol dehydration or difficulty breathing. Also look out for decreased activity and alertness. If your baby鈥檚 lips, tongue or skin turn gray or blue, pick up the phone and call your doctor immediately.听
- Severe cough, especially one that interferes with the ability to stay hydrated.听
- Any new symptoms: All cold viruses can lead to bacterial infections, such as ear or sinus infections or pneumonia. Pay attention to complaints of ear pain or chest pain.听
- Underlying health conditions: Viral illnesses can be more severe in children with asthma or with other underlying conditions.听
Red flags: Signs of serious distress听
Breathing trouble: If your child exhibits fast breathing or increased work with breathing, this can be a sign of respiratory distress. 鈥淎lso watch for the skin at the bottom of the neck or in between the ribs being sucked in or "retracted". Notice grunting, flaring nostrils or congestion in infants that interfere with their ability to drink and stay-hydrated. Dusky or blue color changes to the skin are also a signs of serious breathing problems,鈥 says Dr. Corey Wasserman, Assistant Professor of Clinical Pediatrics at Weill Cornell Medical College and Assistant Attending Pediatrician at NewYork-Presbyterian Hospital.听
Dehydration: Look out for the absence of tears with crying, sunken soft spots in infants or a dry or tacky tongue. 鈥淚nfants or small children who are hard to rouse or lethargic may be dehydrated,鈥 she says. 鈥淎nd decreased urine output also points to dehydration: in an infant, less than one wet diaper every 4 to 6 hours, and in a child, at least every 6-8 hours.鈥听
What can parents do to keep their children from getting sick in the first place?听听
鈥淎s we鈥檝e all learned to do to keep COVID at bay, wash your hands often,鈥 Dr. Rowe says. 鈥淯se soap and water and scrub for at least 20 seconds. And remind your children to practice hand-washing all year round.鈥听
The American Academy of Pediatrics urges parents to keep their children up to date on their immunizations, including an annual flu shot, the COVID-19 vaccine and Tdap to protect against whooping cough. Additionally, it鈥檚 always advisable to keep your children home from school or daycare when they are sick, and teach them to cover their mouths when they cough or sneeze.听
鈥淭ry your best to disinfect objects and surfaces in your home on a regular basis, and avoid exposing your child to smoke from tobacco or other environmental pollutants,鈥 says Dr. Wasserman.鈥 And, if possible, consider feeding your baby breastmilk, which has unique antibodies to prevent and fight infections.听
