Several negative-strand viruses carry their genomeas a set of discrete RNA segments. Examples include influ-enza virus (eight segments), Rift Valley fever virus (threesegments), Hantavirus (three segments), and Lassa virus(two segments), to name a few.

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
