CMV negative, what does it mean?

Question

I am a regular blood donor through the Red Cross. I am AB negatvie blood type, and I'm also CMV negative. I am not infected with HIV. The Red Cross tells me CMV negative type blood is used for transfusions for pre-mature babies, babies, and burn victims, of which I am glad to be of assistance. However, what does it mean to be CMV negative, and are there any adverse health consequences for me? Thank you,

Answer

"CMV negative" means you have never been infected with cytomegalovirus. For most people with healthy immune systems, infection with CMV or not is usually of little consequence, but people with damaged or immature (like newborns) immune systems are susceptible to life-threatening CMV infection. You are lucky.
