‼️⛔️RSV ‼️⛔️
🫁Respiratory syncytial virus (RSV) and bronchiolitis 🫁
You might think parents are overprotective when they don’t want people kissing their babies. This is why.
RSV and other respiratory viruses are currently filling paediatric wards around South Africa. The cooler weather brings the usual sneezes, but it can also increase your baby’s risk of RSV and respiratory viruses.
RSV is one of the most common causes of bronchiolitis in children. Other causes include Rhinovirus, Enterovirus, Parainfluenza, Metapneumovirus and many others.
🫁What is bronchiolitis?🫁
Bronchiolitis is a lower respiratory tract infection caused by a virus. Many viruses can cause bronchiolitis, but RSV is the most well-known one. It occurs predominantly in children below 2 years of age, particularly infants.
RSV is highly contagious, and nearly all children have been infected at least once by the time they reach their second birthday. It causes cold-like symptoms that can lead to breathing difficulties and hospital admission.
RSV causes up to 90% of bronchiolitis hospitalisations and up to 50% of hospital admissions in winter with pneumonia.
🫁What time of year does RSV occur?🫁
RSV is usually seasonal, peaking in autumn and winter. In South Africa, the peak in RSV season varies slightly by province, with the onset of the epidemic usually in KwaZulu-Natal from December to January, in Gauteng from February to March, followed by the Western Cape in March. RSV peaks from February to June, before the influenza season, from May to September.
🫁How is RSV transmitted?🫁
RSV is transmitted from person to person through physical contact, coughing, and sneezing. It can live for hours on surfaces.
Therefore, I cannot reiterate this message any louder:
‼️DO NOT KISS SOMEONE ELSE’S BABY!‼️
Your one kiss or touch can be life-threatening.
Other contributing factors that increase the risk are exposure to to***co smoke, having school-age siblings, attending daycare, and living in crowded conditions.
🫁Who is more at risk for RSV?🫁
Due to their underdeveloped lungs, premature babies and children with chronic lung or congenital heart disease are at the highest risk of severe illness and hospitalisation and may require intensive care.
While adults and healthy children can generally cope with mild cold-like symptoms, at-risk infants are highly likely to be admitted to the hospital. Preterm infants are 2-5 times more likely than full-term infants to be admitted to the hospital for RSV-related symptoms in their first six months of life.
However, even healthy children can be severely affected by RSV and need hospital admission. They may even die from it.
🫁What are the symptoms of RSV?🫁
RSV usually begins with a mild fever, runny nose, sore throat, mild cough, blocked nose, and ear infection.
It appears to be a common cold because, technically, it is!
Most older children and adults will have these symptoms, and the condition subsides. It is essential to understand not every child contracting RSV will end up in hospital; mainly, they just present with a common cold, but if it complicates, then they will most likely need admission.
🫁What are the danger signs?🫁
If the symptoms progress and worsen, you may see wheezing, difficulty breathing, and trouble eating, drinking, or sleeping. Infants, being unable to breathe, won’t feed well, resulting in dehydration, which is one of the reasons for admission.
As the illness progresses, the lung tissue becomes inflamed, sloughs off, and blocks airways. This leads to wheezing and difficulty breathing. In some very severe cases, the child would need to be put on a ventilator in the ICU to help them overcome this respiratory distress.
If you notice your baby's chest pulling in with every breath they take, you should seek medical attention right away. Short, shallow, or rapid breathing and lethargy are red flags for parents during RSV season.
🫁How is RSV treated?🫁
Treatment at home for RSV (or the common cold, as you won’t know how to tell the difference) includes using nasal saline drops, a humidifier to keep the air moist, ensuring the baby drinks enough, and age-appropriate pain and fever medication.
As this is a viral infection, antibiotics would not be indicated. Secondary bacterial infections can occur later, but your doctor will use their discretion when prescribing it.
Most children will recover in 1-2 weeks but can spread the virus for 1-3 weeks, even after recovery.
In-hospital treatment can see children receive intravenous fluids if they are not eating or drinking well, humidified oxygen, or mechanical ventilation.
Physiotherapy and nebulisations have been proven to not be of any benefit.
🫁How can RSV be prevented?🫁
✅Regular washing of hands with soap and water.
✅Teaching kids proper coughing and sneezing etiquette.
✅Keep your child below 2 years away from others with cold symptoms during the RSV season.
✅Wash toys and surfaces that have come in contact with children with cold symptoms.
✅Discourage other people from kissing your baby.
✅Don’t expose your baby to second or third-hand smoke.
✅Try to breastfeed as long as possible.
🫁Is there a vaccine against RSV?🫁
There is no vaccine to prevent RSV, but there is a medication called Palivizumab (Synagis) that may prevent severe LRTIs in children.
It contains virus-fighting antibodies. This is not a vaccine, but it’s an injection given once a month throughout RSV season. This medication is highly costly and is only indicated for children with an extremely high risk of contracting the disease.
High-risk children are infants born prematurely and who are 6 months of age or younger at the beginning of RSV season, as well as babies with lung and/or heart disease.
In South Africa, the injections usually start in January until around June.
Scientists are working toward developing a vaccine for RSV, but right now, no vaccine for the illness is licensed anywhere in the world.
🫁What are the long-term effects of RSV?🫁
Unfortunately, being infected once with RSV does not protect the child from contracting it again.
Some children with complicated RSV continue to have recurrent respiratory symptoms throughout childhood due to lung tissue breakdown and inflammation. It is estimated that of children admitted to the hospital with RSV, almost a third will still suffer recurrent wheezing episodes 10 years later, which may be mistaken for asthma.
RSV can be severe, and it's important to remember that it's okay to say no to an invitation if you're not feeling well or reschedule if a prospective guest tells you they've got a little cold. Sometimes, minor colds can turn into big problems for little babies.
