Many scientists have claimed for months that the new coronavirus can be suspended in microdroplets expelled by patients when speak and breathe, but until now, there was no solid proof to back such claims.
A new study at the University of Nebraska that uploaded to a medical preprint site proves that SARS-CoV-2 have taken from microdroplets, for the first time, defining that under-five microns can replicate in lab conditions.
This boosts the hypothesis that speaking and breathing, not just coughing and sneezing, are responsible for spreading Covid-19. And yes, it was also proved that infectious doses of the virus could travel distances far than the six feet (two meters) that are being urged by social distancers.
Though the results are still considered preliminary and so far, they have not appeared in a peer-reviewed journal, which will make the claims more credible.
The team used a device the size and collected the microbes produced by COVID-19 patients while talking, and some were coughing, the collected microns were as small as one micron in diameter.
They then placed them into a culture to let them grow, and resultantly that three of the 18 samples replicated.
This represents proof that microdroplets, especially those that travel far greater distances than big droplets, can infect people.
