Infection prevention specialist Eli Perencevich, a professor of medicine and epidemiology at the University of Iowa’s College of Medicine, said on Twitter: “Masks won’t protect the average person.
"Because they will wear them incorrectly and autocontaminate themselves."
Prof Perencevich added: "I’ve never seen a person practice hand hygiene before removing a mask in public and then after removing the mask."
He told Forbes that the average healthy person does not need to have a mask.
“There’s no evidence that wearing masks on healthy people will protect them,” he said.
