Why aren’t we talking more about airborne transmission?
Short-distance aerosol transmission changes things a bit:<p>* Social distancing isn&#x27;t enough to guarantee safety in indoors spaces: bad news for bars, clubs, gyms, concerts, and restaurants<p>* Outdoors spaces are probably safer than we previously thought<p>* Indoor mask-wearing becomes CRITICAL in public spaces<p>* Indoor ventilation becomes extra important, using fresh air from outside or filtered&#x2F;UV-sanitized air<p>* Indoor air purifiers with HEPA ratings or UV sterilizer features may become valuable<p>But the same overall guidance still applies: avoid crowds, wear a mask, keep your distance, outdoors activities are safer than indoors activities
