C. quinquefasciatus is one of the many arthropodal vectors responsible for spreading the arboviral encephalitis, West Nile Virus (WNV), to human beings through their bite. West Nile Virus causes symptoms ranging from a mild fever to often fatal effects such as spontaneous bleeding of the skin and circulatory failure.
