More than seven months after the coronavirus was first discovered, scientists and health experts are still trying to understand how it spreads and how we can stop COVID-19. The coronavirus is transmitted from one person to another through "droplet transmission," including direct contact with someone who is infected, indirect contact with contaminated surfaces, droplets from coughing or sneezing, according to the World Health Organization. Airborne transmission is also possible, but its effects and risks have recently sparked a scientific debate, reports abcnews.

But some scientists and researchers are showing increasing evidence that the virus can be transmitted by even smaller droplets called aerosols. They remain in the air for a longer time. What is the difference between aerosols and droplet transmission from sneezing and coughing? Respiratory droplets from sneezes and coughs are larger, five to 10 micrometers in diameter, and the exposure radius is one to two meters.
Aerosols, however, are less than five micrometers in diameter and "travel" beyond two meters from the infected individual. "Coronavirus can survive in both droplets and aerosols for up to three hours under experimental conditions, although this depends on temperature and humidity, ultraviolet light and even the presence of other types of particles in the air," he told Al Jazeera. Stephanie Dancer, a microbiologist in the United Kingdom. "Microscopic aerosols can circulate at least up to six meters indoors. The distance depends on how big the aerosol is." How can the spread of COVID-19 through the air? As in the transmission of droplets, aerosols can be "released" in several ways, including breathing, laughing, sneezing, coughing, singing.
