These days we have seen lots of babies suffering from fever cough and cold and I have often found people asking if its COVID 19? Well, these days we have seen increase in no of cases of Fever cough and cold which is mainly due to RSV – Respiratory Syncytial Virus.

This virus is major cause of respiratory illness in children and may mimic symptoms of COVID – 19 which can be worrisome to parents. Respiratory syncytial virus (RSV) causes infections of the lungs and respiratory tract. It’s so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults.

For most babies and young children, the infection causes nothing more than a cold. But for a small percentage, infection with RSV can lead to serious, sometimes life-threatening problems such as pneumonia or bronchiolitis, an inflammation of the small airways of the lungs. RSV can cause severe infection in some people, including babies 12 months and younger (infants), especially premature infants, older adults, people with heart and lung disease, or anyone with a weak immune system (immunocompromised).

Symptoms

Signs and symptoms of respiratory syncytial virus infection most commonly appear about four to six days after exposure to the virus. In adults and older children, RSV usually causes mild cold-like signs and symptoms. These may include:

• Congested or runny nose
• Dry cough
• Low-grade fever
• Sore throat
• Sneezing
• Headache

In severe cases

RSV infection can spread to the lower respiratory tract, causing pneumonia or bronchiolitis — inflammation of the small airway passages entering the lungs. Signs and symptoms may include:

• Fever
• Severe cough
• Wheezing — a high-pitched noise that’s usually heard on breathing out (exhaling)
• Rapid breathing or difficulty breathing — the person may prefer to sit up rather than lie down
• Bluish color of the skin due to lack of oxygen (cyanosis)

Infants are most severely affected by RSV. Signs and symptoms of severe RSV infection in infants include:

• Short, shallow and rapid breathing
• Struggling to breathe — chest muscles and skin pull inward with each breath
• Cough
• Poor feeding
• Unusual tiredness (lethargy)
• Irritability

Most children recover in one to two weeks, although some might have repeated wheezing. Severe or life-threatening infection requiring a hospital stay may occur in premature infants or in anyone who has chronic heart or lung problems.

RSV and COVID-19

Because RSV and coronavirus disease 2019 (COVID-19) are both types of respiratory viruses, some symptoms of RSV and COVID-19 can be similar. In children, COVID-19 often results in mild symptoms such as fever, runny nose and cough.

Having RSV may lower immunity and increase the risk of getting COVID-19 — for kids. And these infections may occur together, which can worsen the severity of COVID-19 illness.

If you have symptoms of a respiratory illness, your doctor may recommend testing for COVID-19.

When to see a doctor

Seek immediate medical attention if your child — or anyone at risk of severe RSV infection — has difficulty breathing, a high fever, or a blue color to the skin, particularly on the lips and in the nail beds.

Prevention

No vaccine exists for respiratory syncytial virus. But these lifestyle habits can help prevent the spread of this infection:

• Wash your hands frequently. Teach your children the importance of hand-washing.
• Avoid exposure. Cover your mouth and nose when you cough or sneeze. Limit your baby’s contact with people who have fevers or colds.
• Keep things clean. Make sure kitchen and bathroom countertops, doorknobs, and handles are clean. Discard used tissues right away.
• Don’t share drinking glasses with others. Use your own glass or disposable cups when you or someone else is sick. Label each person’s cup.
• Don’t smoke. Babies who are exposed to tobacco smoke have a higher risk of getting RSV and potentially more-severe symptoms. If you do smoke, never do so inside the house or car.
• Wash toys regularly. Do this especially when your child or a playmate is sick.
