What is RSV?
Respiratory syncytial virus, or RSV, is a virus that infects the lungs and respiratory tract causing cold-like symptoms.
How common or infectious is RSV?
It's so common that most children have been infected with it by the time they're 2 years old.
What are the symptoms?
In adults and older children, signs of respiratory syncytial virus (RSV) infection typically manifest as a mild congested or drippy nose, along with a dry cough.
Additional symptoms could include a slight rise in body temperature, a scratchy throat, and a minor headache. More severe RSV infections may lead to symptoms such as a heightened fever, pronounced coughing, wheezing, rapid or laboured breathing, and a bluish tinge to the skin.
Infants affected by RSV may exhibit inward movement of the chest muscles and skin during each breath as they struggle to breathe. They may also experience coughing, shallow and rapid breaths, and difficulties with feeding.
Unusual fatigue and increased irritability are other symptoms commonly observed in infants with RSV.
It is important to note that because RSV and coronavirus disease 2019 (COVID-19) belong to the respiratory virus category, some symptoms of RSV and COVID-19 may overlap.
Complications associated with respiratory syncytial virus include:
- Middle Ear Infection: Infection in the space behind the eardrum can lead to middle ear infections (otitis media). This is more common in babies and young children.
- Asthma: There may be a correlation between severe RSV infections in children and an increased risk of developing asthma later in life.
- Recurrent Infections: After experiencing an RSV infection, the possibility of reinfection exists, even within the same RSV season. However, subsequent infections typically present with milder symptoms resembling a common cold. Nevertheless, they can pose a significant risk to older adults or individuals with chronic heart or lung conditions.
- Pneumonia: RSV is the primary cause of lung inflammation (pneumonia) and inflammation of the airways in the lungs (bronchiolitis) among infants. These complications arise when the virus spreads to the lower respiratory tract. Lung inflammation can be particularly severe in infants, young children, older adults, individuals with weakened immune systems, or those with chronic heart or lung conditions.
Remedies for Managing RSV Symptoms
Like common colds, there is no specific medication to eliminate RSV. However, you can alleviate your child's discomfort at home by following these measures:
Clear Congestion: If your child struggles with nasal congestion and is unable to blow their nose, consider using a few drops of nasal saline in each nostril. Employ a suction device, such as a bulb syringe, to remove the mucus.
Steam: Run a hot shower or use steamy baths. The water vapor helps loosen congestion.
Honey: If your child is at least one year old, you can try giving them honey to alleviate coughing. Honey is as effective as popular over-the-counter cough medications but without the side effects.
Alleviate Pain: Provide Calpol (for those over 2 months old) or ibuprofen (for those over 3 months old) as necessary to manage fever or discomfort. These medications can help alleviate muscle aches, headaches, and sore throats.
Maintain Hydration: For infants, breast milk or formula are the best sources of hydration due to their nutritional content. For older children, diversify their fluid intake. Ensure their fluids contain some salt and sugar if they are not eating solid foods. Apple juice, water, popsicles, milk, soup, and hydrating foods like watermelon and cucumbers are excellent options.
Determining When to Seek Medical Care for Your Child
When it comes to deciding whether your child's cold requires medical attention, trust your parental instincts.
If you're uncertain, reach out to your GP or pharmacist.
In general, be vigilant for the following indicators of a more severe case:
Breathing Difficulties, which can manifest as:
- Rapid breathing
- Use of additional muscles for breathing (observe for the use of shoulders or the abdomen to breathe, and watch for the skin between the ribs retracting with each breath)
- Grunting at the end of each breath
- Nostril flaring during each breath
- Pale or blue lips/mouth
- Inability to simultaneously breathe and drink
Lethargy
Dehydration: Most children typically urinate every three to six hours. You are familiar with your child's normal patterns. If you encounter difficulties in maintaining their hydration and they urinate less frequently than usual, medical attention is necessary. Other signs of dehydration include a dry mouth, lethargy, and the absence of tears when crying.
Pain: Similar to other colds, a child with RSV may develop conditions such as ear infections, pneumonia, or sinus infections. Pay attention to any complaints of ear, chest, or sinus pain.'
