Why children do not get sick from the corona virus and how they fight it like any other child virus

Australian children avoid the deadly corona virus thanks to their robust immune system and healthy, young lungs, experts said.

In news that is likely to be welcomed by my thousands of parents, young people show remarkably mild symptoms of the disease – less than 1 percent of cases.

The killer strain of the corona virus has killed more than 3,100 people worldwide and infected 41 people in Australia – including only one child.

But children’s immune systems are strong, with their young lungs not yet affected by pollutants or smoking, and usually have no underlying health problems.

This means that if they get the virus, they probably won’t get sick of it – and probably show no symptoms at all.

It is the same with other infectious diseases, such as chickenpox or measles, where the older a person is, the more severe the disease.

Health Minister Greg Hunt said the news would serve as an “important reassurance” for families.

“One of the most important reassurances for families is the evidence we have about limited portability to children,” he said.

“That’s very important for families and parents, and then the mild impact on those kids on the evidence around the world.”

WHAT SYMPTOMS GETS CHILDREN?

Chinese doctors report infected children often have cough, stuffy nose, runny nose, diarrhea and headache.

But less than half of the children have a fever and many have no symptoms at all.

Of the children and teenagers who contracted COVID-19 in China, the majority had mild infections and recovered within fourteen days.

Even babies only had mild infections.

Now officially known as COVID-19, the virus has infected more than 90,000 people worldwide.

But of the approximately 44,000 cases in China, the epicenter of the disease, fewer than 1 percent are children nine years of age or younger.

Although more than 3,100 people have died, this does not include children.

“One of the most recognized consequences of aging is a decrease in immune function,” a researcher found in the Journal of Clinical Investigation.

‘Although the elderly are by no means immunodeficient, they often do not respond efficiently to new or previously found antigens.

“This is illustrated by the increased vulnerability of people aged 70 and older to flu.”

Children also show much milder symptoms, such as a runny nose or cough.

“I thank evidence all over the world that when children are infected, they are incredibly mild, in fact so mild that they have almost no symptoms,” said Australia’s chief health officer, Brendan Murphy.

“The only child we have infected in Australia meets those criteria.

“We are not entirely sure to what extent they get the virus, but we do know that symptomatic significant disease is not a feature and we have received very few indications of a significant problem in children.

‘And that is very different from flu, where we often have a few pretty sick children. So that’s a good positive message. “

Proofessor Robert Booy of the National Center for Immunization Research and Surveillance added: “Those children who have contracted the virus abroad only have mild symptoms such as fever and upper respiratory tract symptoms,” he said.

“In adults, they react quite violently because they may have seen a previous coronavirus infection and the immune system has been set up to react inappropriately and excessively.”

A similar phenomenon was evident during the SARS outbreak in 2002.

No children or teenagers died from the disease, which also originated in China, and had much lower infections.

“One of the interesting things about this virus is the very small number of children that appear to be infected, certainly in the Chinese experience,” Mr. Murphy added.

“That means that children are not particularly susceptible, or that if they do, they get such a mild disease that it has not been discovered.

“Whatever the reason, that’s a good thing and we haven’t seen much evidence of serious infections in children.”

Researchers from the Multinational Influenza Seasonal Mortality Study (MISMS) discovered that there can be many reasons why children prevent them from getting the disease.

They discovered that a large number of cases are found in people who travel internationally, who are more adults than children.

But more importantly, the severity of the virus is associated with the presence of chronic conditions – which are more common in adults.

A detailed analysis by MISMS experts showed that even in one Chinese household where five members of the same family had a corona virus in Wuhan, a 10-year-old in the same family remained asymptomatic.

But experts at the Center for Disease Control and Prevention warned that, like with other respiratory diseases, certain populations of children may be at increased risk of serious infections.

This includes young people with underlying health problems.

Researchers at the epicenter of the virus in Wuhan suggested that the virus cannot pass from pregnant women to fetuses.

The study, published in the Lancet, evaluated nine pregnant women who had coronavirus.

All women were in their third trimester and gave birth via caesarean section – but no one passed on the virus to their child.

Scientists took samples from amniotic fluid, umbilical cord blood, breast milk and neonatal throat smears, and all were found to contain no traces of the virus.
