Alarming footage reveals how much corona virus droplets remain in the air after coughing!


A video clip reveals how corona virus droplets can remain swimming in the air for an hour after someone coughs.

And experts at Mater Hospital in Dublin, Ireland, used a high-speed camera to test the effectiveness of different types of face coverings.

They found that wearing a surgical mask or a cloth cap reduced the amount of suspended droplets in the air.

But without any protection, their experiment showed that the aerosol can be pushed over two meters – and stay in the air for an hour.

The research was led by Dr Kevin Nolan, an engineer at University College Dublin, and Ronan Cahill, professor of surgery at Mater Hospital, and was conducted using two different methods: the Schlieren technique – a process that uses high-specification mirrors and light to show the density of liquids and gases, as well as the speed and distance they can travel When someone breathes, coughs, or sneezes.

Dr. Nolan told the newspaper Irish Times: “We can see that the large droplets fall quickly to the ground while the smaller particles that could contain the virus remain in the atmosphere. When a person with” Covid-19 “coughs or sneezes, some particles carry the virus and others do not.”

Because Schlieren technology does not cover large distances, the team has also devised a method that uses high-powered lasers to show how far droplets can travel and how long they can stay in the air.

Dr Nolan said their shared experiences revealed that wearing the mask had a significant effect on the extent to which the drops could travel.

He added, “The conspiracy theorists will make you think that masks cannot work, because viruses are very small and can be transmitted through materials, but this misunderstands the science.”

The researchers also found that aerosols carrying “Covid-19” could be excreted through the abdomen during laparoscopic surgery, which could put entire teams of doctors at risk.

They stressed the importance of the employees taking extra precautions when it comes to performing laparoscopic surgeries on “Covid” patients.

Dr Cahill added that the results make it easy to visualize what exactly is happening within the environment, when someone expels the spray.

Experts hope the findings will allow paramedics to adjust their practices, including ventilation, wearing masks, and how people move around the operating room.
