TLDR
The investigation of this cluster documents the transmission of West Nile virus by organ transplantation and suggests organ recipients receiving immunosuppressive drugs may be at high risk for severe disease after West Nileirus infection.Abstract:
Background In August 2002, fever and mental-status changes developed in recipients of organs from a common donor. Transmission of West Nile virus through organ transplantation was suspected. Methods We reviewed medical records, conducted interviews, and collected blood and tissue samples for testing with a variety of assays. Persons who donated blood to the organ donor and associated blood components were identified and tested for West Nile virus. Results We identified West Nile virus infection in the organ donor and in all four organ recipients. Encephalitis developed in three of the organ recipients, and febrile illness developed in one. Three recipients became seropositive for West Nile virus IgM antibody; the fourth recipient had brain tissue that was positive for West Nile virus by isolation and nucleic acid and antigen assays. Serum specimens obtained from the organ donor before and immediately after blood transfusions showed no evidence of West Nile virus; however, serum and plasma samples obtained...read more

Infection in Solid-Organ Transplant Recipients
TL;DR: The clinician assesses a recipient’s risk of infection while considering the risk of allograft rejection, the intensity of immunosuppression, and other factors that may contribute to his or her susceptibility to infection.

Emerging flaviviruses: the spread and resurgence of Japanese encephalitis, West Nile and dengue viruses
TL;DR: Three examples of emerging and resurging diseases of global significance are described: the resurgence of dengue in tropical and subtropical areas of the world, and the spread and establishment of Japanese encephalitis and West Nile viruses in new habitats and environments.

TL;DR: Screening of potential donors with the use of nucleic acid-based assays for West Nile virus may reduce this risk of acquisition of the virus through transfused red cells, platelets, and fresh-frozen plasma.

TL;DR: In this paper, an unusual cluster of cases of meningoencephalitis associated with muscle weakness was reported to the New York City Department of Health and the initial epidemiologic and environmental investigations suggested an arboviral cause.

TL;DR: The TaqMan assay was specific for WN virus and demonstrated a greater sensitivity than the traditional RT-PCR method and correctly identified WNirus in 100% of the culture-positive mosquito pools and 98% ofthe culture- positive avian tissue samples.

TL;DR: The epidemic in Bucharest reflected increased regional WNF transmission in 1996 and Epidemics of Cx pipiens-borne WNF could occur in other European cities with conditions conducive to transmission.

TL;DR: The virus's rapid geographic expansion and subsequent persistence in newly established enzootic areas in North America indicate that West Nile virus has become a permanent fixture of the U.S. medical landscape.
