Unfortunately, influenza can not be controlled effectively. A number of
factors are responsible for insufficient control of this disease. Viral ubiquity and
transmissibility, a high spreading rate of the influenza virus, antigenic selection,
antiviral treatment etc., are responsible for the control of influenza. The main properties
of the influenza virus described in the previous chapters that may influence the control
of influenza are listed in this chapter.
