The new strain of wheat stem rust fungus is primarily spreading around the world through wind dispersal of spores. This allows for the fungus to travel long distances and infect new areas quickly. While it is possible for the fungus to be carried on imported infected wheat, this is not the primary mode of transmission. It is also not known to be spread through viral vectors or carried by birds.
