Steeds meer wetenschappers geven Maurice de Hond gelijk: Covid19 wel degelijk verspreid door aerosolen, WHO haalt schouders op

“The World Health Organization and the U.S. Centers for Disease Control and Prevention maintain that you have to worry about only two types of transmission: inhaling respiratory droplets from an infected person in your immediate vicinity or — less common — touching a contaminated surface and then your eyes, nose or mouth.

But other experts contend that the guidance ignores growing evidence that a third pathway also plays a significant role in contagion.

They say multiple studies demonstrate that particles known as aerosols — microscopic versions of standard respiratory droplets — can hang in the air for long periods and float dozens of feet, making poorly ventilated rooms, buses and other confined spaces dangerous, even when people stay six feet from one another.

“We are 100% sure about this,” said Lidia Morawska, a professor of atmospheric sciences and environmental engineering at Queensland University of Technology in Brisbane, Australia.

She makes the case in an open letter to the WHO accusing the United Nations agency of failing to issue appropriate warnings about the risk. A total of 239 researchers from 32 countries signed the letter, which is set to be published next week in a scientific journal.

Jose Jimenez, a University of Colorado chemist who signed the letter, said the idea of aerosol transmission should not frighten people. “It’s not like the virus has changed,” he said. “We think the virus has been transmitted this way all along, and knowing about it helps protect us.”

He and other scientists cited several studies supporting the idea that aerosol transmission is a serious threat.”
