Additional information

  West Nile Virus is a flavivirus, similar to Dengue Virus, which causes a wide spectrum of infection. This may range from no or minimal symptoms to death. It is geographically widespread, including areas in Europe and other parts of the world not affected by malaria, and it has reached epidemic proportions in North America in recent years. Mild cases may be misdiagnosed as other febrile illnesses.

  The processes used to fractionate plasma include several measures that inactivate or remove viruses. This means that some travel risks described in the Geographical Disease Risk Index do not need to be applied for donors who will only donate plasma for fractionation.
