WTF? What kind of viral infection can see you get sick, recover, then get sick with a reinfection with the same virus weeks later?
I thought once you get a viral infection and fight it off, you now have antibodies that protect you from getting sick again from that particular virus. Curious as to the science behind this reinfection mechanism.
