Topic: Aerosol Transmission

As US confirmed cases surpassed 100,000, hospitals nationwide prepared for a surge in patients and a shortage of ventilators. Medical experts emphasized that the primary mode of transmission is from hands to the face (eyes, nose, or mouth). While aerosolized transmission was considered a possibility, experts believed it required long, sustained contact in enclosed spaces.

The CDC updates its website to emphasize that inhalation of aerosols is a primary method of COVID-19 transmission, de-emphasizing surface contact. This information appeared on the New York Times opinion page rather than the science section. The hosts note that this shift in guidance was discussed by independent researchers a year prior.

California theme parks including Disneyland and Knott's Berry Farm are implementing new COVID-19 safety guidelines that discourage screaming on roller coasters to prevent the spread of droplets. The California Attractions and Parks Association supports the plan, citing concerns over sputum and aerosol transmission. Skepticism is raised regarding why nasal swabs are required for testing if the virus is primarily spread through oral emissions.

Dr. David Price of Weill Cornell Medical Center describes COVID-19 transmission as occurring almost exclusively through sustained contact and hand-to-face transfer. He emphasizes that the virus is not easily caught through casual contact and that masks serve primarily as a reminder not to touch one's face. The hosts compare this information to the more alarmist coverage found in US media versus international outlets like Al Jazeera.
