WHO Advised to Swap Surgical Face Masks with Respirators Amid Growing Concerns Over Protection Against Flu-Like Illnesses
A group of experts has urged World Health Organization (WHO) chief Dr Tedros Adhanom Ghebreyesus to swap surgical face masks with respirator-level masks in healthcare settings, citing inadequate protection against airborne pathogens.
The proposal, backed by 50 senior clinicians and researchers, as well as over 2,000 members of the public, argues that surgical masks are no longer sufficient for preventing transmission of flu-like illnesses, including COVID-19. According to Prof Adam Finkel, a signatory and expert at the University of Michigan School of Public Health, surgical masks were designed to prevent doctors and nurses from spreading germs, but "are obsolete" compared to respirators.
Respirators, such as FFP2/3 standards in the UK or N95 in the US, are designed to filter tiny particles and meet high filtration standards. The experts argue that these masks should be standard practice for medical interactions, resulting in fewer infections in patients and healthcare professionals, and reducing rates of sickness, absence, and burnout in the health workforce.
Critics of the proposal point to a lack of randomized controlled trials showing physical measures slow the spread of respiratory viruses, but the authors argue that laboratory tests demonstrating respirators' effectiveness are sufficient evidence.
The WHO has been criticized for its handling of the COVID-19 pandemic, including its initial characterization of the virus. The letter also calls for the organization to revisit earlier statements and provide clear guidance on how the virus spreads via airborne respiratory particles.
As production of surgical masks is phased down, the WHO's procurement infrastructure could help increase access to respirators in poorer countries. The experts suggest that this change could have a significant impact on reducing the spread of infectious diseases in healthcare settings.
While the proposal may be met with controversy, particularly given face mask debates during the pandemic, the authors argue that it is necessary to prioritize evidence-based policies and protect healthcare workers from infection.
