Omicron Variant Less Severe Than Delta For Children Younger Than 5 Years: Study

Washington: Children younger than five years who are infected with Omicron have less risk of severe health outcomes than those infected with the Delta variant of coronavirus, according to a study. The research, published in the journal JAMA Pediatrics, is the first large-scale study to compare the health outcomes of coronavirus infection from Omicron and Delta in the age group which is not yet vaccinated. The finding led by researchers at the Case Western Reserve University in the US show that the Omicron variant is 6-8 times more infectious than the Delta variant.

The severe clinical outcomes ranged from a 16 per cent lower risk for emergency room visits to 85 per cent less risk for mechanical ventilation, the researchers said. About 1.8 per cent of children infected with Omicron were hospitalised, compared to 3.3 per cent with Delta, they said.

The major conclusion to our research was that many more children were infected with Omicron when compared to Delta, but the children who are infected are not impacted as severely as were children infected with the Delta variant, said Pamela Davis, a research professor at the Case Western Reserve School of Medicine. She added,

However, because there are so many more children infected, our hospitals were affected over the winter months by an influx of young children.

The team analysed the electronic health records of more than 651,640 children in the US, including over 22,772 children infected with the Omicron variant and more than 66,000 children infected with Delta.

The study also compared the records of more than 10,000 children immediately before the detection of Omicron in the US, but when Delta was still predominant.

The researchers noted that children younger than five years are not yet eligible for COVID-19 vaccines and have a low rate of previous SARS-CoV-2 infections, which also limits their pre-existing immunity.

They examined clinical health outcomes for pediatric patients during a 14-day window following SARS-CoV-2 infection.

Among the factors they reviewed were: emergency room visits, hospitalisations, ICU admissions and mechanical ventilation use.

Analysing the demographic data, the researchers found that children infected with Omicron were on average younger — 1.5 years of age versus 1.7 years — and had fewer comorbidities.

Rong Xu, from Case Western Reserve School of Medicine, noted that Omicron is less severe than Delta, however, the reduction of the severity range in clinical outcomes is only 16 to 85 per cent.

Furthermore, since so many un-vaccinated children were infected, the long-term effects of COVID-19 infections on the brain, heart, immune systems and other organs of children remains unknown and worrisome, Rong Xu added.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ population, indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity,  that is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
