Influenza

Influenza is highly infectious disease and the influenza viruses are a considerable threat to human health all around the world. The prevention and treatment of the disease can be done by vaccines and antiviral substances, but only with certain limitations. The virus is a highly notorious one, and rapidly mutates via genetic drift (characterized by point mutations in antigenically important positions caused by selective pressure from host immune response) and genetic shift (characterized by a substitution of a whole gene from one subtype to another), re-surfacing as an uncontrolled pathogen for massive destruction
