Video warning about what a single sneeze is doing inside the supermarket


An animation group demonstrates how corona virus particles can spread from one sneeze into the air for “several minutes” and reach two supermarket corridors.

Scientists have devised a computer simulation to study the extent to which a virus can be transmitted inward, and have found worrying results about how a cloud of virus-filled drops will affect others, even after a patient has left.

Scientists say the best way to avoid getting infected with the virus is to get away from crowded public places such as shops and stations.

Professor Phil Vorinin, from the University of Alto, Finland, told BBC News that it was necessary to reduce the number of shopping times as possible and go to shops and boutiques as absolutely necessary, making sure to stay there for the shortest possible time.

The scientists said in a statement accompanying the video: “Initial results indicate that the aerosol particles that carry the virus can remain in the air for a longer period than originally thought, so it is important to avoid crowded public places.”

They added: “This also reduces the risk of droplet infection, which is still the main factor for transmission of the SK virus.”

The study was conducted by scientists from the Finnish University of Alto, the Finnish Meteorological Institute, the VTT Technical Research Center in Finland, and the University of Finland.

Experts looked at how small airborne particles in the air travel when they are released from the respiratory system when they sneeze, cough, or even speak.

They said: “In the situation under investigation, an aerosol cloud will spread outside the immediate vicinity of the person who sneezed, and then this process will weaken. However, this can take several minutes.”

They continued: “Very small particles of this size do not fall to the ground, but instead, they move along the air currents or remain floating in the same place.”

Professor Furenin said: “A person with the virus can cough and move away, but then leave behind very small particles of aerosols carrying the coronavirus, and these particles can end up in the respiratory system of others in the vicinity.”

Although there is growing evidence that people can become infected with the virus and have no symptoms, the World Health Organization does not believe it is necessary for people to wear face masks.
