Viral Winds
Scientists have for the first time determined that astounding numbers of viruses are being swept up from the Earth’s surface and blown around the world in the planet’s atmospheric circulation.
Researchers from Spain, Canada and the United States believe there are at least 800 million viruses per square meter from just above the surface to the stratosphere.
The global winds are spreading them, as well as bacteria, for thousands of miles, possibly from one continent to another.
The scientists say the bacteria and viruses become airborne after winds pick them up in dust and sea spray.
