ATLANTA - Health officials are questioning whether the blood supply is spreading the West Nile disease. <br>
<br>
Four people have been diagnosed with West Nile after receiving blood transfusions. <br>
<br>
The Centers for Disease Control and Prevention reported Thursday that at least one of the four got blood products from donors who were later found to be carrying the virus. <br>
<br>
The CDC also confirmed that a Georgia woman who died in a car accident in July passed on the West Nile virus through organ donations to four people. <br>
<br>
Previously doctors said they weren't sure whether the organ recipients got West Nile from the organ transplant or from a mosquito. <br>
<br>
The report said mosquitoes ``most likely'' caused West Nile in the four blood recipients, but that it's possible they caught the virus from an infected blood donor.
