Re-examining 153 cases of infectious hepatitis patients in Akaiwa area, Okayama Prefecture, the result was that some cases seemed to have distinctly shifted to chronic hepatitis, along with cases of latent hepatitis without conscious symptoms, to the extent of about 1/8 of total cases; moreover, there were pretty many who should be taken care of: where, there were few cases of perfect recovery. Besides, 2 cases were recognized which shifted tohepatic cirrhosis, one of which could be given testimony owing to autopsy. The chronic turn like this was of course seen in serious cases, but even in slightly-affected cases, if thorough treatment was out of use (esp., quiet repose); so that, in its treatment, utmost care should be taken; besides, as to the decision of recovery, one should take resort to every means to ensure it
