Who is at risk?
- People over 50 years of age and those with compromised immune systems are at the highest at risk of developing severe complications.
- Risk through medical procedures is very low. All donated blood is checked for WNV before being used. The risk of getting WNV through blood transfusions and organ transplants is very small, and should not prevent people who need surgery from having it. If you have concerns, talk to your doctor.
