For reasons unknown, children rarely have severe symptoms when infected by COVID-19 and may even be a bit less likely to get the disease in the first place, experts told AFP.

But that doesn’t mean infants, toddlers and teens are not carriers for the new coronavirus, which jumped from animals to humans in central China at the end of last year.

As of Friday, there were over 140,000 confirmed cases in 124 countries, with more than 5,000 deaths.

Experts estimate that the true number of infections — many with mild or no symptoms — is far higher.

“We know children get infected with the virus, but they don’t appear to get very sick or die,” said Justin Lessler, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health.

“What we don’t know is how much these asymptomatic or mildly symptomatic kids transmit,” he told AFP. “This is key to understanding their role in the epidemic.”
