  • Description:
    Thursday, October 03, 2002, 05:09 EDT (5:09 AM EDT) CDCHAN -00102-2002-10-03-UPD–N As of 2 October, the total number of West Nile virus cases reported to CDC reached 2,530 with 125 deaths in 32 states and Washington D.C. have reported human cases of West Nile virus in 2002. The CDC, the Food and Drug Administration, the Health Resources and Services Administration, in collaboration with blood collection agencies and state and local health departments, continue to investigate WNV infections in recipients of blood products and organ transplantation. CDC has received reports from 10 states of 15 patients with confirmed West Nile infection diagnosed after receiving blood products within 1 month of illness onset. It is likely that not all of the 15 patients were infected via blood products; all lived in areas with active West Nile virus activity and thus m ay have been infected via mosquito bites. To recap the investigation so far, West Nile virus transmission from blood products has been confirmed in three patients. In a Mississippi investigation, West Nile virus w s cultured from a blood product associated with a blood donor of one of the cases. In a Michigan investigation, two patients tested positive for WNV infection after receiving different blood products derived from a single blood donation subsequently found to have evidence of WNV.
