COVID-19: Coughing without masks, distancing alone is not enough

Researchers from McGill University found that unmasked individuals can spread COVID-19 airborne particles up to 70% within a 2-meter radius, highlighting the need for mask-wearing and ventilation. The study suggests that current guidelines relying solely on physical distancing may not be sufficient to prevent transmission.
