ABSTRACT
Meningoencephalitis caused by the human herpes virus 6 is common in acquired immune deficiency syndrome patients or in patients after organ transplantation, rarely in immunocompetent adults. The clinical manifestations include headache, drowsinesss, coma, epileptic attack, psychiatric symptom and focal neurological signs. Antiviral therapy is effective, however the prognosis should be poor if the treatment is not timely. The clinical data of one case of meningoencephalitis caused by the human herpes virus 6 in Tianjin Haihe Hospital in October 2019 were analyzed. Meningoencephalitis caused by the human herpes virus 6 can be recurrent. The clinical manifestations are nonspecific and the diagnosis is difficult. The next generation sequencing of cerebrospinal fluid is a powerful method to identify pathogens.
