It has been reported that there are approximately one thousand annual cases of infantile viral encephalitis and encephalopathy in Japan. There are, however, no available information regarding its causative agent, prognosis, pathogenesis, and treatment except for HSV and influenza encephalopathy. Here, I review the recent advances from the two research programs on influenza and other encephalopathy in Japan supported by MEXT and MHLW.
