Simultaneous acute infections with hepatitis non-A, non-B, and B viruses

A case of overt acute hepatitis acquired through accidental needle stick was reported. The episode of hepatitis was classified as non-A, non-B because no hepatitis B marker or IgM-anti-HAV was detected during the peak of hepatitis. Concurrent with non-A, non-B hepatitis, subclinical acute hepatitis B virus infection might have developed as evidence by de novo hepatitis B seroconversion 6 weeks later. It was concluded that hepatitis B and non-A, non-B viruses can be transmitted simultaneous by the same carrier, and can acutely infect the recipient simultaneously with possible viral interference.
