: WNV is a RNA virus transmitted by mosquitoes. The infection primarily involves birds; humans are incidental hosts. WNV was first recognized in the United States in 1999, when it caused an epidemic of meningoencephalitis on the east coast. It has been reported recently that WNV can be transmitted by organ transplantation. While detection of specific IgM antibody remains the choice of test for diagnosis, molecular testing has been the sensitive and specific testing for screening organs/cells in the transplantation service.
