The threat of catching the West Nile virus extends past just mosquito bites. The threat may now be in blood transfusions.
The virus is known to be in some of the nation's blood supply, according to the Food and Drug Administration.
Health officials at the American Red Cross in Lansing say there's been no case in the region where the virus has been transferred through blood.
Officials at Ingham Regional Medical Center say most surgeries don't require blood transfusions. But there are alternatives like patients donating their own blood. In case of emergency though, they say there aren't many.
The Red Cross says they actively screen their donors for symptoms of any illness and ask donors to call if any symptoms arise later.
