Over the past few months, a lot of controversy surrounding how SARS-CoV-2, the virus responsible for COVID-19, travels between infected persons. While official advice wasn’t obvious, some aerosol scientists and health experts cleared out that the virus’s spread in aerosols paid a significant role in spreading it.
In July, a total of 239 scientists from 32 countries urged the WHO (World Health Organization) to analyze the possible role of airborne transmission in the spread of the virus.
After three days, the WHO stated that under some conditions, “short-range aerosol transmission, particularly in specific indoor locations, such as crowded and inadequately ventilated spaces over a prolonged period with infected persons, cannot be ruled out.”
Many scientists reached out to people on social media when the CDC agreed with their discoveries, reckoning the news for the first time in a September 18 website update that aerosols play a significant role in spreading the virus.
The update claimed that the novel virus could spread “through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes. These particles can be inhaled into the nose, mouth, airways, and lungs and cause infection. This is thought to be the main way the virus spreads.”
Protecting Against The Virus
Atmospheric chemist Kimberly Prather, airborne virus expert Linsey Marr and environmental health professor Donald Milton spoke about the best precautions you should take to decrease the risk of contracting the virus.
- Practice distancing – the farther from others, the better.
- Wear a mask when you are close to others, even when you stay away from them
- Try to keep windows open to improve ventilation
- If possible, clean the air effectively with methods like filtration.
- Wear a mask if you can’t physically distance by over six feet or more.
- Try to move group activities outside. That decreases the risk severely.
