WHO Advised to Swap Surgical Face Masks with Respirators Amid Global Criticisms Over Inadequate Protection Against Airborne Pathogens.
A group of medical experts has urged the World Health Organization (WHO) to update its guidelines, recommending that surgical face masks be replaced by respirator-level masks in healthcare settings. The experts argue that surgical masks provide inadequate protection against flu-like illnesses, including COVID-19, and are no longer suitable for use in hospitals and clinics.
The group of seven clinicians and scientists, led by Prof Adam Finkel from the University of Michigan School of Public Health, claims that respirators designed to filter tiny particles would significantly reduce infections among patients and healthcare workers. The authors point out that surgical masks were never designed to prevent airborne pathogens but rather to prevent medical professionals from sneezing into patient wounds.
In contrast, respirator-level masks meet high filtration standards and fit closely around the face, filtering out airborne germs. Finkel likens respiratory masks to computer technology, stating that they are like typewriters to modern computers β obsolete.
While critics argue that there is a lack of randomized controlled trials demonstrating the effectiveness of physical measures in slowing the spread of respiratory viruses, the authors contend that laboratory tests showing respirators' ability to stop particles provide sufficient evidence. The group has received support from prominent figures, including researchers and public health advocates.
The WHO has faced criticism for its initial slow response to describing COVID-19 as airborne. Now, a revised update is being considered, which could have a significant impact on global guidelines for infection prevention in healthcare settings. However, there may be scenarios where respirators are not necessary, depending on community infection rates and ventilation or air filtration devices.
As the pandemic continues to evolve, updated guidance from the WHO could help prevent further spread of respiratory viruses among patients and healthcare workers.
