Experts Urge WHO to Revise Approach to Emerging Respiratory Viruses, Emphasizing Airborne Precautions
————————————
A group of infectious disease specialists is calling on the World Health Organization (WHO) to fundamentally revise its strategy for responding to emerging respiratory viruses, urging a stronger emphasis on airborne transmission prevention rather than waiting for definitive proof before acting.

The appeal, made in an opinion piece published in the British Medical Journal (BMJ) and widely discussed in public health circles, calls for the adoption of precautionary measures — such as the use of respirators, improved ventilation, and advanced air filtration — early in an outbreak to reduce the spread of respiratory pathogens.

According to the experts, who include leading researchers in airborne virus transmission, WHO’s current default response often downplays airborne transmission until it is conclusively proven, which can delay critical interventions. They argue that masks, adequate airflow, and high‑efficiency particulate air (HEPA) filtration should be part of frontline public health guidance from the outset in settings where respiratory viruses might spread.

This call reflects a broader debate in global health policy about how respiratory diseases — including those caused by novel viruses — should be managed, especially in light of evidence highlighting the role of airborne particles in transmission. Proponents say that acting early with such measures can protect healthcare workers, patients, and the broader community while reducing overall disease spread.
