Children may be able to spread Covid-19 just as easily as they spread another type of coronavirus -- the common cold, said William Haseltine, a former professor at Harvard Medical School.
“There’s every reason to suspect that this virus, even though it can kill you, behaves pretty much like a cold virus, in terms of transmission. Who drives colds? Children drive colds,” Haseltine told CNN’s Anderson Cooper Monday.
“And that's true of almost all respiratory diseases, including the colds that are caused by coronaviruses. And this is one of those cousins,” he added. “It even uses the same receptor in the nasal passages as one of the cold viruses. It just happens to be a cold virus that also kills.”
Haseltine warned that children can be infected and infect others, so they should wear masks.
He said that children up to 5 years old can be “highly infectious to other people."
"It turns out they have a thousand times more virus in their nose than you need to infect, so they're very, very contagious," Haseltine said.
