COVID-19: Long Symptoms of Coronavirus Delta Variant Less Likely to Affect Children, Study Finds

COVID-19: Does increase in number of cases after Scottish schools reopen suggest infections could increase UK-wide?

Children and teens are unlikely to develop other prolonged symptoms of COVID-19 after 12 weeks, according to a new study.

The Murdoch Children’s Research Institute (MCRI) in Australia conducted research on the Delta variant of deadly virus after 10 months of circulation of the strain.

The results showed that the variant did not cause more severe symptoms in young and healthy children, with most cases being recorded as asymptomatic or mild.

However, research also found that children and teens were at greater risk for more severe symptoms if they suffered from health conditions such as obesity, chronic kidney disease, cardiovascular disease, and immune disorders.

A recent review indicated that severe COVID-19 was likely in 5.1% of children and adolescents who had pre-existing conditions

MCRI professor Nigel Curtis said children infected with Sars-CoV-2 were usually asymptomatic or had mild illness.

But he added that it was still too early to determine the long-term effects of long-term COVID-19 in people.

He said: “Current studies lack a clear case definition and age-related data, have variable follow-up times, and are based on symptoms reported by themselves or by parents without laboratory confirmation.

“Another significant problem is that many studies have low response rates, which means they could overestimate the risk of COVID-19 long. “

What do teens think about the COVID vaccine?

It comes after a recent systematic review said severe COVID-19 was likely in 5.1% of children and adolescents who had pre-existing conditions, rather than 0.2% of those without conditions.

Dr Petra Zimmermann, of MCRI and University of Friborg, added that it was difficult to accurately determine the risks of COVID-19 in children and adolescents due to the pandemic causing social distancing by the shutdown schools, not seeing friends and being unable to play sports or hobbies.

The review was published in the Pediatric Infectious Disease Journal and reviewed 14 international studies involving 19,426 children and adolescents with persistent symptoms.

The most common symptoms reported up to 12 weeks after registration of infection in young people were headache, fatigue, trouble sleeping, difficulty concentrating, and abdominal pain.
