The Influenza virus has genetic material inside the nucleus in order for the the virus to duplicate and make more copies that can infect humans or animals. There are spikes of protein molecules on the outer shell of the envelope that attack other cells with the virus. The ‘H spikes’ are used to infect other cells whereas the ‘N spikes’ are used to break away from the infected cells once copies are made to infect more cells. These “spikes” are known as protein molecules, hemagglutinin and neuraminidase. There are 16 known hemagglutinin molecules and 9 neuraminidase. The flu viruses are named depending on how many hemagglutinins and neuraminidase proteins are attached. For example, the most common influenza A viruses H1N1 and H3N1. An individual
