De Hond-sceptici:
“ in an open letter to the WHO, 239 scientists in 32 countries have outlined the evidence showing that smaller particles can infect people and are calling for the agency to revise its recommendations. ....
Interviews with nearly 20 scientists —
including a dozen WHO consultants and several members of the committee that crafted the [WHO] guidance — and internal emails paint a picture of an organization that, despite good intentions, is out of step with science.....
“They’ll die defending their view,” said one
long-standing WHO consultant, who did not wish to be identified because of her continuing work for the organization. Even its staunchest supporters said the committee should diversify its expertise and relax its criteria for proof, especially in a fast-moving outbreak.
“I do get frustrated about the issues of airflow and sizing of particles, absolutely,” said Mary-Louise McLaws,
a committee member and epidemiologist at the University of New South Wales in Sydney.
“At the country level,
a lot of WHO technical staff are scratching their heads,” said a consultant at a regional office in Southeast Asia,
“If we started revisiting airflow, we would have to be prepared to change a lot of what we do,” she said. “I think it’s a good idea, a very good idea, but
it will cause an enormous shudder through the infection control society.” [en daarom wil de WHO er niet aan]
....
In early April, a group of 36 experts on air quality and aerosols urged the WHO to consider the
growing evidence on airborne transmission of the coronavirus. ....
In most buildings, ..., “the
air-exchange rate is usually much lower, allowing virus to accumulate in the air and pose a greater risk.”...
Marr and others said the coronavirus seemed to be most infectious when people were in prolonged contact at close range, especially
indoors, and even more so in
superspreader events — exactly what scientists would expect from aerosol transmission.
Ventilation systems in schools, nursing homes, residences and businesses may need to
minimize recirculating air and add powerful new
filters. Ultraviolet lights may be needed to kill viral particles floating in tiny droplets indoors.
