How does the flu virus infect humans from an animal host? O An influenza virus gains new sequences of DNA from another virus, such as a herpesvirus; this enables it to be transmitted to a human host. The flu virus in a pig is mutated and replicated in alternate arrangements so that humans who eat the pig products can be infected. A flu virus from a human epidemic or pandemic infects birds; the birds replicate the virus differently and then pass it back to humans. An animal such as a pig is infected with more than one virus, genetic recombination occurs, the new virus mutates, the virus is passed to a new species such as a bird, and the virus mutates again and can now be transmitted to humans.

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.
