Face Masks Are 'Inadequate', Says WHO, Must Be Swapped For Respirators

Face <span>masks</span> are not adequate when it comes to protection against <span>flu</span>-like illnesses, including COVID, said the World Health Organization (WHO) guidelines. As the number of flu cases rise in the US and the UK, this WHO guideline, may be of use. The guidelines noted that the surgical masks worn by doctors and nurses, when they are face to face with a patients are no longer providing the protection, and must be replaced with respirators. 

The guidelines noted in a letter to the WHO chief Dr Tedros Adhanom Ghebreyesus, noted there is “no rational justification remaining for prioritizing or using” the surgical masks that are ubiquitous in hospitals and clinics globally, given their “inadequate protection against airborne pathogens”. “There is even less justification for allowing healthcare workers to wear no face covering at all,” the letter read. 

When COVID was at its peak, an estimated of 129 billion disposable face masks were being used around the world every month. These were used by the healthcare workers as well as general public. These surgical masks were most widely available and recommended by most health authorities during that time. However, respirators were then designed to filter tiny particles. Then came the masks FFP2/3 standards in the UK or the N95 in the US. Evidence also supported that many countries are switching to these masks and that they are more effective. This resulted in fewer infections in patients and health professionals, as well as reducing the rate of sickness, and burnout of the healthcare professionals. 

<h2>What Is The Key Difference Between Respirator and Surgical Mask?</h2>

Face masks are loose in fitting and are designed for one-way protection. It protects others from coughs and sneezes. WHO recommends a three-layer mask when people cannot socially distance. However, not all face masks have a safety rating. 

The respirators on the other hand has a tight fitting, which creates a facial seal and filters both inflow and outflow of air. It tightly covers the nose and the mouth. It also removes 94% of all particles that are 0.3 microns in diameter or larger. It is also designed to protect the wear up to the safety rating of the mask. 

The WHO has faced criticism for its delayed acknowledgment of Covid-19’s airborne transmission. The letter urges the agency to reassess its earlier position and clearly communicate to the public that the virus spreads through airborne respiratory particles.

Professor Trisha Greenhalgh of the University of Oxford, a signatory to the letter whose research is widely cited in it, said that infection occurs only when germs enter the body. She explained that respirators, which seal tightly against the face, force air to pass through high-grade filters that block airborne pathogens. In contrast, she noted, medical masks fit loosely and allow significant air leakage.

Supporters of the letter include members of the World Health Network, leading US epidemiologist Eric Feigl-Ding, and Guardian columnist George Monbiot.

Responding to the letter, a WHO spokesperson said it would undergo “careful review.” The spokesperson added that the organization consults experts across diverse health and economic settings when developing guidance on personal protective equipment for healthcare workers, and that its Infection Prevention and Control guidelines for epidemic- and pandemic-prone respiratory infections are currently under review in light of the latest scientific evidence.
