Most recently, in 1994 Deka et al reported that novel viral particles had been discovered in the stool of post-transfusion, non-hepatitis A, non-hepatitis B, non-hepatitis C, non-hepatitis E patients. Injection of these particles, into the bloodstream of Indian rhesus monkeys caused hepatitis, and the virus was named hepatitis F, or Toga virus. Further investigations failed to confirm the existence of the virus, and it was delisted as a cause for infectious hepatitis. ,

The next confirmed hepatitis virus was hepatitis G.
