COVID-19 is Airborne

This Viewpoint suggests that infection control guidelines should be re-evaluated to account for the predominance of small particles within infectious aerosols. Protective devices available to health-care workers have a range of protection, increasing from surgical masks to filtering facepiece respirators to powered air-purifying respirators. Although these are indicated for close encounters, their limitations highlight the need for improved administrative controls, such as more rapid diagnosis and isolation, and the development of vaccines and treatments. These data support calls for the recognition of aerosol (ie, traditional airborne) transmission of SARS-CoV-2.144 This could facilitate the use of enhanced dilution and directional ventilation and other environmental control options—eg, air disinfection with ultraviolet germicidal irradiation,145 which might be especially helpful in congregate settings such as nursing homes. Implementation of improved infection control measures could prevent future morbidity and mortality among health-care workers.

It is airborne. I wish they would just come out and say the word airborne in the media that is targeted at the general public. The average person isn’t going to care about the vagaries of the scientific definition of airborne. A reproduction rate over 5 (which COVID can have) means that the transmission is functionally airborne. Why quibble over the semantics?

If airborne transmission were shown to be a major factor, some experts have suggested it could be helpful to wear masks indoors, even in settings where social distancing is being enforced; that tighter regulations may be needed for ventilation and air conditioning to minimise recirculating air; and that it may even be appropriate to install UV lights in some buildings to guard against potentially infectious particles.

This article from the New York Times details investigations into methods of transmission aboard the Diamond Princess back in January. Nothing short of a properly adjusted N95 mask or multiple layers of cloth over the mouth and nose will keep you from catching the disease when someone is standing next to you has it. This makes Trump’s fumbling of the supply chains even more damning than I initially thought it was. If masks had been mandatory and available early, a good portion of the deaths we have seen across the country could have been avoided.
