The Benefits of Diluting Aerosols to Prevent Airborne Transmission
The COVID-19 pandemic has brought to light the importance of understanding how the virus spreads and what measures can be taken to prevent its transmission. One method that has been known for centuries to be effective in combating airborne transmission is diluting aerosols. However, recent actions by the World Health Organization (WHO), led by Mike Ryan and John Conly, have hindered progress in this area and left us stuck with outdated droplet dogma.

Aerosols are tiny particles that can remain suspended in the air for extended periods of time. These particles can contain viruses and other pathogens, making them a potential source of transmission. Diluting aerosols involves increasing the ventilation and air circulation in indoor spaces, effectively reducing the concentration of these particles and limiting the risk of transmission.
The benefits of diluting aerosols are well-documented and have been recognized for centuries. In the 18th century, physicians and scientists understood the importance of fresh air and ventilation in preventing the spread of diseases such as tuberculosis. This knowledge was further reinforced during the 1918 influenza pandemic, where open-air hospitals saw significantly lower mortality rates compared to traditional closed facilities.
Despite this historical evidence, recent guidelines from the WHO have focused primarily on the transmission of the virus through droplets, downplaying the significance of aerosols. This droplet dogma has caused a delay in recognizing the importance of diluting aerosols in preventing airborne transmission. However, mounting scientific evidence suggests that aerosols play a crucial role in the spread of COVID-19.
A study published in the journal Nature found that aerosols containing the SARS-CoV-2 virus can remain infectious for up to 16 hours, highlighting the potential for airborne transmission. Another study conducted in a restaurant in Guangzhou, China, showed that airflow patterns and ventilation played a significant role in the transmission of the virus among diners. These findings emphasize the need for diluting aerosols to reduce the risk of infection.

By diluting aerosols, we can effectively decrease the concentration of viral particles in the air, making it less likely for individuals to inhale infectious doses. Increasing ventilation, using air purifiers, and implementing other measures that promote air circulation can all contribute to diluting aerosols and reducing the risk of airborne transmission.
It is crucial for organizations like the WHO to acknowledge the benefits of diluting aerosols and update their guidelines accordingly. By focusing solely on droplet transmission, we are neglecting an important aspect of preventing the spread of COVID-19. The adoption of a comprehensive approach that includes both droplet and aerosol transmission will be key in effectively combating the virus.
Furthermore, diluting aerosols not only helps in preventing COVID-19 transmission but also has long-term benefits for overall indoor air quality. Improved ventilation and air circulation can reduce the concentration of other pollutants, allergens, and volatile organic compounds, leading to a healthier indoor environment.
In conclusion, the benefits of diluting aerosols to prevent airborne transmission have been recognized for centuries. However, recent actions by the WHO have hindered progress in this area and favored droplet dogma. It is crucial to acknowledge the role of aerosols in the spread of COVID-19 and adopt strategies that effectively dilute these particles. By doing so, we can not only reduce the risk of infection but also improve indoor air quality in the long run.
