- New research shows that talking can be an even bigger coronavirus transmission risk than coughing.
- Talking for just 30 seconds is enough for an infected person to spread aerosols with a higher viral concentration than a single cough. These aerosols can linger in the air for longer than droplets ejected via coughs or sneezes, which fall and settle on surfaces much faster.
- The study further underscores the importance of health measures to limit the spread of COVID-19, including face masks, social distancing, frequent hand washing, and proper ventilation.
The novel coronavirus is still surging in several countries, with a few mutations helping drive the recent increases in cases. The holidays are also partially responsible for the current surge in cases, since many people traveled and failed to take some of the basic precautions that can reduce transmission risk. The virus spreads with ease via microscopic saliva droplets of varying sizes that are expelled during coughing, sneezing, and even just talking. The bigger droplets tend to land on surfaces somewhat quickly, but the smaller ones can become aerosols as the water quickly evaporates. Those aerosols can then linger in the air for a longer period of time. That’s why health officials advise people to respect all health recommendations to prevent COVID-19 spread, including face masks, social distancing, hand hygiene, and proper ventilation of indoor spaces. All of these measures are meant to reduce the risk of someone coming into contact with droplets expelled by an infected person.
Now, a brand new study explains something that everyone out there should take note of.
