Influenza virus particles. Computer artwork ofinfluenza (flu) virus particles with people in thebackground. Each particle comprises a core(central sphere) surrounded by membranes. Theouter membrane bears the proteins neuraminidase and haemagglutinin (spikes), which help the virus to enter a host cell. Thevirus uses its host cell's genetic machinery toproduce more copies of itself. These copies make anew outer membrane from the cell's own membraneand erupt from the cell to infect others. Theinfluenza virus is a type of Orthomyxovirus. Itcauses fever, weakness and aching muscles.. Stunning Photo Gifts From Science Photo Library
