People under 20 are around half as susceptible to Covid-19 as people aged 20 or above, according to research published on Tuesday, and clinical symptoms of the pandemic disease appear in only about a fifth of infections in children and teens.
The research, a modelling study using data from 32 locations China, Italy, Japan, Singapore, Canada and South Korea, found that by contrast, Covid-19 symptoms appear in 69 per cent of infections in people aged 70 or older.
The findings suggest that school closures - introduced in many countries as part of lockdowns aimed at controlling the coronavirus pandemic - are likely to have a limited impact on transmission of the disease, the researchers said.
Published in the journal Nature Medicine, the study compared the effect school closures on simulated outbreaks of flu - which is known to spread swiftly in children - and of Covid-19, the disease caused by the new coronavirus.
"For Covid-19, there was much less of an effect of school closures," said Rosalind Eggo, an infectious disease modeller at The London School of Hygiene and Tropical Medicine who co-led the study.
She added, however, that the findings come from simulated outbreaks and need to be reinforced with real-world research.
Using demographic data from the six countries, as well as from six studies on estimated Covid-19 infection rates and symptom severity across different age groups, the model showed that people under 20 are about half as susceptible to Covid-19 as people over 20, and that among 10 to 19 year-olds, only 21 per cent of those infected had clinical symptoms.
The researchers also simulated Covid-19 epidemics in 146 capital cities around the world and found that the total expected number of clinical cases varied with median age.
"The age structure of a population can have a significant impact," said Nicholas Davies, who co-led the work. "Countries with more young people may experience a lower burden of Covid-19."

$1,000 award for 1,000 days on madrasa portal
Daily cash awards of $1,000 dollars will sweeten the Madrasa e-learning project by tempting more pupils to an education portal to deepen their understanding of math and sciences.
School children are required to watch an educational video each day and answer a question related to it. They then enter into a raffle draw for the $1,000 prize.
“We are targeting everyone who wants to learn. This will be $1,000 for 1,000 days so there will be a winner every day for 1,000 days,” said Sara Al Nuaimi, project manager of the Madrasa e-learning platform that was launched on Tuesday by the Vice President and Ruler of Dubai, to reach Arab pupils from kindergarten to grade 12 with educational videos.
“The objective of the Madrasa is to become the number one reference for all Arab students in the world. The 5,000 videos we have online is just the beginning, we have big ambitions. Today in the Arab world there are 50 million students. We want to reach everyone who is willing to learn.”
