Suara.com – The Covid-19 pandemic is far from over, and the shocking findings of this new study warn us why we should continue to be cautious about the deadly virus.
If you thought the only way to catch SARS-COV-2 was when respiratory droplets were transmitted through direct contact or air, think again. Even the simple act of talking to someone can transmit that much virus!
By far, the most common way for Covid-19 to spread from one person to another is through direct contact with droplets, aerosol transmission (where droplets can remain or settle on surfaces) or by talking.
However, there are differences between the types of contagious droplets that are produced when a person talks or coughs. Talking, or breathing, for example, produces many tiny droplets that can move for longer, and are more contagious. So talking and talking become activities that are more risky than coughing.
Evidence of this problem may also point to reasons why Covid-19 can spread so easily indoors rather than outdoors, among large crowds.
Small droplets can also be a greater risk for indirect transmission. Micro-sized droplets, such as those produced by speaking or breathing can also travel longer distances via aerosol transmission, which has been shown in previous research as well.
Experts have now broken the code that it only takes seconds for a droplet to travel more than 2 meters.
Scientists based at the Royal Society A built a model that analyzes the rate of transmission of droplets depending on the mode of transmission – coughing, talking, sneezing, droplet arrangement and the time it takes for them to settle down.
In the model setting, it was observed that although the number of infectious particles in the air began to decrease 1-7 minutes after coughing, the act of speaking for 30 seconds held more particles in the air for up to 30 minutes. This implies that infectious particles would be much more dangerous if they were spread by speaking than by coughing.

It also appears that a person is more likely to catch it if he or she stands near a person who is talking or even breathing with a high viral load.
