Well, this didn't even pass my mind, but I'm sure it is worth considering... for what it's worth... Personally , I find this interesting as to all the chit-chat about the possibility of spacedust bringing in pathogenics that cause pandemics on Earth.
We'll just have to wait and see what becomes of this, won't we.
Russian meteor threw up globe-circling plume of debris that lingered for months
Some of the pieces from the meteorite fell to the ground, but the explosion also deposited dust into the atmosphere

Gorkavyi led the study examining data on the dust collected by NASA satellites. The study has now been accepted for publication by the journal Geophysical Research Letters.
“Indeed, we saw the formation of a new dust belt in Earth’s stratosphere, and achieved the first space-based observation of the long-term evolution of a bolide plume,” said Gorkavyi.
To do so, the team used both satellite measurements and atmospheric modeling to simulate how the plume of dust from the meteorite would evolve. The stratospheric jet stream carried the plume slowly toward the Northern Hemisphere, allowing the scientists to make their observations. About 3.5 hours after the initial explosion, the Ozone Mapping Profiling Suite instrument’s Limb Profiler on the NASA-NOAA Suomi National Polar-orbiting Partnership satellite was able to detect the plume at about 25 miles up into the atmosphere.
On February 16, the day after the explosion, the plume was detected moving towards the Aleutian Islands. Larger, heavier particles began to lose speed while the lighter particles cruised on. By February 19, the plume had made its way back to Chelyabinsk, where it had originated.
However, this was not the end of the story for the dust. Three months later the scientists were still able to detect signs of it. Atmospheric models supported their observations of the plume’s journey.
