After seeing the VA's memo, Rep. Chris Collins, a Republican who represents the Buffalo area, said he spoke with Dr. Robert A. Petzel, undersecretary for health at the Department of Veterans Affairs.
"His thought was that it's a very, very low chance of passing infection," Collins said. "But it's not out of the realm of possibility, and that's why they're testing everyone," Collins told the News.
Collins said that even with a fresh needle, contamination could have occurred if bodily fluid flowed back into the insulin pens.
The VA said it is offering free blood tests to rule out any infections.
