Corona: infection with the Virus on suspended particles in the air – the göttingen scientists studied fine dust-aerosols and advises to the safety distance, in spite of the protection mask.

Göttingen – In poorly ventilated areas, threatens the Transfer of the Coronavirus by floating particles in the air, called aerosols. Prior to that, the göttingen chemist Thomas Zeuch warns. High humidity increase the risk of Infection with the Coronavirus in addition.
“aerosols are mixtures of solid and liquid particles suspended in a Gas,” explained the unscheduled Professor. He conducts research at the Institute of Physical chemistry of the University of Göttingen about fine-dust aerosols, in which coronaviruses can be located.
The particles in an Aerosol are smaller than five microns. For comparison: A human hair has a diameter of 50 to 70 micrometers.
Coronavirus: göttingen scientists explored particles
brave The light particles of the force of gravity and not fall to the ground. So they float for hours in the air and can cause an infection, for example, with the Coronavirus through the respiratory tract, even if the infectious Person has already left the room.

“However is so far still relatively unexplored, how long the new coronaviruses in aerosols remain contagious,” stresses Zeuch. Dehydration destroys it. The faster, the lower the humidity is.
By Airing of the rooms decreases their concentration in the air, which reduces the Corona risk of infection also significantly. Therefore, virologists rates to Meet under the open sky.
Corona: According to the göttingen-based scientists only special masks, protection
“protection against Inhalation of aerosols offer special masks we wear in the me-led chemistry workshops at the University of Göttingen ,” says Zeuch. However, difficult such masks values, the Breathing so much that no one wanted to voluntarily, for longer than a half hour.
“The best mask to use is also nothing if not the eyes are also protected, for example through special glasses,” says Zeuch. On the conjunctiva there namely also a Corona infections. Therefore, you should not RUB with the unwashed hands, the eyes.
“The today prescribed mouth-nose masks made of cloth to provide the wearer with no protection,” emphasizes Zeuch. Therefore, he advises, make sure to keep because of the current Corona pandemic, a safety distance of one and a half to two meters – to the extent that droplets fly in normal Speak.

Because there are Sneezing, even up to eight meters, you should use the crook of your arm. More than five micron-sized droplets decrease, in contrast to the Aerosol particles to the ground. “The masks are useful because you Exhale the majority of the droplets back,” explains the Professor.
Corona: scientists in göttingen advises, masks every day to wash
The carrier to protect others from infection. Clinic staff is therefore always masks, if it has contact to debilitated patients.
“has been underestimated This danger at the beginning of the Corona pandemic,” says Zeuch. Only with time had become clear that Corona -Infected showed up to 14 days with no symptoms. In this time the Coronavirus in your mouth and throat area increase, however. Via droplets and aerosols, they arrived in the area.
“masks should be washed daily at 60 degrees or in the oven to be sterilized,” says Zeuch. So virus would be killed.
