They're everywhere around us, they plant disease.

According to the results of the new research, “viruses and bacteria fall above our heads”. Scientists say that a large number of different kinds of bacteria and viruses circulate our atmosphere and fall to the ground, but also on us, and not only that, viruses and bacteria that are in us can have “grown” from other continents.

Micro-bacteria are scattered in the dust of the earth, the surface of the sea, the evaporation of the sea, or the particles of aerosol seawater in space beneath the free troposphere. The air currents can rise above the clouds but also below the stratosphere, where airplanes fly. At this height viruses and bacteria can be carried thousands of miles before they return to the earth's surface.

“Every day, more than 800 million viruses are stored per square meter above the planetary border layer or 25 viruses per person in Canada, said Curtis Suttle, a virologist at the University of British Columbia in Vancouver. The rate of deposits for viruses is 9 to 461 times higher than for bacteria. Some 20 years ago, similar genetic viruses were found in different environments worldwide. This explains that despite the long-term stay and travel of the virus through the atmosphere, it is possible that they enter the atmosphere” on one continent and “dalen” on the other side.

Scientists worry that certain viruses and bacteria that cause infectious diseases and are resistant to long - term atmosphere and extreme climate conditions can in some cases transmit diseases from one continent to another remote continent. Research results have recently been published by the International Association for Microbiological Ecology.
