Treatment

Peramivir, Zanamivir, Oseltamivir, Ibuprofen, Acetaminophen, Guaifenesin, Dextromethorphan. These lessen pain, and stop the virus from spreading.

How it replicates

Usually the virus targets the upper respiratory tract and has many was to invade a host. Cap snatching- the virus enters the host through an endosome and enters the nucleus, but the virus RNA is negative and then transported into positive by polymerase proteins and exported out of the nucleus.

Response

The active immunity reacts quickly by recognizing the virus to control the viruses replication. Toll-like receptors in endosomes bind to a single stranded RNA which are important triggers to the effects of influenza. If you have had influenza before the body has already made antibodies to fight the particular type of virus either preventing infection or lessining the result.
