Omicron in Children: 5 Things Parents Must Know

omicron in children

It was just after the new year in 2022 when Mr. Jitin (name changed) started worrying about his 8-year-old son. He had developed a high-grade fever all of a sudden, with a temperature of 103°F. For obvious concerns, Mr. Jitin got him tested for COVID RT-PCR but his report was negative.

“There was a decline in temperature with paracetamol and sponging, but in one episode fever even spiked to 104°F with chills. We were really perplexed,” said Mr. Jitin. It was only on the 3rd day after getting the fever that his son was confirmed COVID positive on repeat RT PCR testing.

Many such cases have been reported by parents across different cities. Experts say, “Children under 5 years of age have narrower airways [1], which makes it easier for germs to sit where the omicron variant grows. This viral replication causes inflammation in the body. High fever is a response to this inflammation.” At large, symptoms of Omicron in children are similar to that of adults including sore throat, tiredness, body ache, and fever [2].

Here are 5 things which every parent must know about Omicron in children:

1. Must-know #1 RT-PCR can be negative in the early days of illness

– Your child may have classic COVID symptoms like fever, cough, [3] however, the gold-standard RT-PCR test report could be negative.

– One possible explanation is that the testing happened too early. Though RT-PCR test is extremely sensitive, a certain threshold of viral particles must be reached before the test can catch it.

What can you do about it?

The optimal timing for RT-PCR tests is 2-4 days after the onset of symptoms, although many kids can test positive sooner than this.

If your child has COVID-like symptoms in the current situation of the third wave, consider it as COVID and take all precautions accordingly. Make sure to connect to a doctor and get guidance.

2. Must-know #2 Stick to the basics: Comfortable clothing, sponging, and hydration

– Dressing: It is a natural reflex to cover the child with multiple blankets and warm clothings as chills or shivering comes. Do not overdress or put extra blankets on. Let the clothes be comfortable. Excess clothing tends to trap body heat and cause the temperature to rise.

– Sponging: Use tepid water (neither hot nor cold to the touch) for sponging from head to toe for 15 mins after giving the fever medication. DO NOT use ice-cold water. To get the most out of it, keep the water film moving over the body (and don’t hold too much at one body area) for maximum temperature regulation.

– Hydration: Optimum fluid intake is very important. As a natural response to fever, the body attempts to lower the temperature naturally through extensive sweating. If your kid doesn’t take enough fluids to replenish, he/she is likely to get dehydrated. Give lukewarm water as small, multiple sips. It helps bring down the core temperature and prevents dehydration too.

3. Must-know #3: Paracetamol and Ibuprofen are medicines used in children for bringing the fever down.

Paracetamol is the safest anti-fever medicine for children. The dose can be repeated after 4–6 hours. [4] Sometimes a combination of paracetamol and ibuprofen is given to have a rapid response. Do not use aspirin or nimesulide for fever relief in children. (These are two commonly used medicines for minor pain and fevers in adults.)

If paracetamol appears unable to bring down the fever, remember these:

– If the initial fever was high, say 104°F, administration of paracetamol may bring it down to 101°F and not make the child afebrile. If you see a downward trend in temperature, consider it is working.

– Remember, the purpose of fever medicine is not to bring down the temperature to normal level but to provide symptomatic relief to the child by reducing pain and discomfort.

– Avoid overdosing if the fever does not normalize. You can repeat the next dose after 4–6 hours if required.

– Paracetamol may start showing effect within 15-30 mins. The maximum effect comes after nearly 1.5 hours. [5]

– Paracetamol dosing depends on your child’s weight (and not age) and strength of medicine. Adequate dose of paracetamol for kids is 10-15 mg/kg. Different strengths of paracetamol syrups are available to cater to diverse pediatric needs. This helps reduce the amount/volume of syrup to be given and could be helpful.

– Other medicines (ibuprofen, mefenamic acid) are also available and should be used only in consultation with your pediatrician.

– Do not panic. Meanwhile, use tepid sponging. Adjust clothing if it is too tight or dressed up.

NOTE: Don’t check temperature too often

Usually, you can measure 3-4 times in a day, at a gap of four to six hours. However, if the first temperature is very high, you might decide to recheck the temperature on a more regular schedule, maybe once or twice an hour.

4. Must-know #4: Anti-allergic medicines as prescribed by your doctor should be regularly given.

Anti-allergic medicines including cetirizine, levocetirizine, fexofenadine and loratadine, etc., have well-documented effectiveness in children. They help in relieving congestion, runny nose, and mucus buildup. Remember, do not treat your kids on your own or with your medicines. Follow dosage as advised by your child specialist.

5. Must-know #5: Know the warning signs: When a fever may need hospitalization

Visit the child specialist if your child is younger than 3 years of age or have any of the following:

– Extreme lethargy, drowsiness, excessive cry or irritation
– Headache, neck stiffness, or breathing difficulty
– Abnormal body movements or behavior
– Temperature above 104°F
– Fever persisting for more than 5 days

Similarly, in a child with fever, the following signs should make you relaxed:

– Playful and active during interfebrile period
– Acts like himself/herself during most of the day
– Feeding well
– Passing urine normally

IMPORTANT: Seizures during fever in babies don’t cause brain damage.

Sometimes, fever can trigger seizures in kids, most commonly in the age group of 6 months to 5 years. These are called febrile seizures, and they can run in the family. They can be just seconds long and usually last less than one minute. Febrile seizures do not result in brain damage or epilepsy.

The final word
While more data is being gathered around omicron in children, it is crucial to keep your child’s guards up with COVID-appropriate behavior and stay informed.
