Children could get more dangerous illnesses according to new study

Children: Although the fatal virus’s transmission has slowed after the 2020 Covid-19 pandemic, there is still much to learn about Covid.

The goal of researchers is to better understand the virus.

Children under the age of five who test positive for another respiratory virus are likely to develop worse, according to recent studies.

They also develop more diseases.

According to a research published on Wednesday in the journal Pediatrics, children hospitalized under the age of five who test positive for Covid and other respiratory viruses have a twofold risk of getting severe respiratory illnesses.

The study

Studies were carried out at a time when children’s hospitals were overrun by respiratory diseases such RSV, flu, Covid-19, and others.

The results demonstrate how these diseases affect children’s hospitals.

It also shows how keeping surveillance of Covid-19 and other viruses might help forecast future peaks in hospitalization.

The study was carried out by researchers from the US Centers for Disease Control and Prevention as well as from other universities and health organizations across the USA.

Firsthand account

Jenevieve Silva remarked that it would be challenging to care for kids who have several respiratory illnesses throughout the pandemic.

Silva is a mother of eight who resides in San Jose, California.

She has dealt with several diseases since her twin boys’ preschool enrollment in May 2021 as toddlers.

“The height of the illness was from September through mid-November, when our household just could not catch a break,” she said.

In October 2022, her twins tested positive for Covid-19.

After some time, they received a diagnosis from their doctor for what they subsequently discovered to be a different respiratory condition, probably brought on by the respiratory syncytial virus, or RSV.

“Based on what the pediatrician told us, she said, ‘I highly believe that they had these overlapping viruses,'” said Silva.

According to Silva, the symptoms include:

  • Shortness of breath
  • Cough
  • Fatigue
  • Fever

In addition, one twin had a 105 degree temperature for four consecutive days.

Despite the fact that giving her sons warm showers and using Vicks VaporRub on their backs and chests helped them deal with the discomfort, Jenevieve Silva stated that it was difficult to see her children go through this.

“They had just looked so frail – they looked sick, like something deeper than back-to-back viruses,” noted Silva.

“It was hell. I mean, it was really bad.”


In the end, Jenevieve Silva’s boys’ ailments were resolved.

She is still concerned that their fevers may have contributed to them developing asthma even though they are doing well today and have gained a lot of weight.

The twins’ sicknesses overlapped in October, and according to Silva, the doctor indicated that it appeared to have possibly caused asthma since then.

When the kids have a cold, they could experience symptoms of asthma, including vomiting and coughing.

“I can’t be the only mom dealing with virus after virus,” Silva said.

“Be patient. Listen to your doctor.”


The findings from the most recent study include 4,372 children who were hospitalized on Covid-19.

A codetection—the presence of several other viruses—was found in 21% of people who had other respiratory viruses examined.

Researchers assert that they were focusing on codetection rather than coinfection.

It’s possible that the children weren’t actually sick despite the fact that both viruses tested positive.

According to the study, just a few respiratory viruses were detected during the first year of the pandemic.

In the first two years of the pandemic, few cases of influenza were documented, but during the Delta-predominant phase, RSV and rhinovirus (or enterovirus) infections spiked.

The statistics showed that children under the age of five made up the bulk of children with codetections.

They were also more likely to require additional oxygen support and be admitted to intensive care units.

RSV-positive infants who receive Covid commonly have life-threatening infections.

Pandemic lessons

According to Dr. Ascuncion Mejias, an associate professor of pediatric infectious diseases at Nationwide Children’s Hospital, the kids who were identified as having Covid-19 and other viral codetections frequently required critical care and oxygen support.

“Covid is a very proinflammatory virus, so it really weakens your immune response,” said Mejias.

“And when you haven’t recovered yet, and you get a second hit, in this case, RSV or rhinovirus, you develop a more severe disease.”

According to Dr. William Schaffner, a professor in the Division of Infectious Disease at Vanderbilt University Medical Center, the results of this study underline the importance of making sure that children get their immunizations on time.

Mejias expressed her viewpoint and emphasized the necessity of safe practices in order to reduce the transmission of diseases to newborns who are too young to get vaccines.

“The pandemic taught us how contagious these viruses are,” said Mejias. “If somebody is sick, try to avoid contact.”

“These viruses are not only transmitted by saliva and secretions, but by hands. It can survive in your hands for more than 30 minutes.”

“So if you touch your mouth and then touch a little baby, the baby can self inoculate the virus and become infected.”

“So washing hands and all these measures are very important.”
