WebJun 29, 2009 · Reassortment can only occur between influenza viruses of the same type. Why influenza A viruses never exchange RNA segments with influenza B or C viruses is not understood. However, the reason is probably linked to the packaging mechanism that ensures that each influenza virion contains at least one copy of each RNA segment.
