Masking up is back again as China faces a major strain of a new Covid mutation virus outbreak yet again, and the rest of the world gears up for protection and precautions. Wearing the mask is one of the many precautions we all have been taking but let’s go a bit deeper into the spread of the disease with Lydia Bourouiba, a fluid dynamics expert and disease transmission at MIT, who explains how the physics of sneezes and coughs through exhalation leads to the spread of respiratory pathogens like COVID-19 in this article from the-scientist.com.
The Covid-19 virus created a reckless havoc around the world and its strains do not seem to go away. How this virus travels from one body to another is the question that led to several researches and studies. Epidemiologists discovered that airborne transmission is the most understudied mechanism that contributes to the spread of viruses like Covid and other pathogens that affect the respiratory system and reside in respiratory fluids. Let us understand the physics of how simple coughs and sneezes transmit diseases from one person to another.
