Acute necrotizing encephalopathy (ANE) or sometimes necrotizing encephalitis or infection-induced acute encephalopathy (IIAE) is a rare type of brain disease (encephalopathy) that occurs following a viral infection. [4] Most commonly, it develops secondary to infection with influenza A, influenza B, and the human herpes virus 6. ANE can be ...
The case-fatality rate of untreated encephalitis syndrome is 56–75%, [5] but early treatment of raised intracranial pressure reduces fatality rate. Of 27 children surviving encephalitis syndrome 24 completely recovered within 3 months, only two developed late onset refractory epilepsy and four continued to have hemiplegia after 8 months. [7]
It is estimated to affect at least 1 in 500,000 individuals per year, [1] and some studies suggest an incidence rate of 5.9 cases per 100,000 live births. [2] About 90% of cases of herpes encephalitis are caused by herpes simplex virus-1 (HSV-1), the same virus that causes cold sores.
Viral encephalitis can occur either as a direct effect of an acute infection, or as one of the sequelae of a latent infection. The majority of viral cases of encephalitis have an unknown cause; however, the most common identifiable cause of viral encephalitis is from herpes simplex infection. [12]
At least 129 children have now died of Acute Encephalitis Syndrome (AES) in the town of Muzaffarpur in the eastern Indian state of Bihar since an outbreak earlier this month, a medical official ...
The incidence of viral encephalitis is about 3.5 to 7.5 per 100,000 people, with the highest incidence among the young and the elderly. Viral encephalitis caused by some viruses, such as the measles virus and the mumps virus, has become less common due to widespread vaccination.
The condition primarily affects children, teens, and young adults. It has been estimated that about 2 in 10,000 people who get measles will eventually develop SSPE. [1] However, a 2016 study estimated that the rate for unvaccinated infants under 15 months was as high as 1 in 609. [2] [3] No cure for SSPE exists, and the condition is almost ...
Lymphocytic choriomeningitis (LCM) is a rodent-borne viral infectious disease that presents as aseptic meningitis, encephalitis or meningoencephalitis. Its causative agent is lymphocytic choriomeningitis mammarenavirus (LCMV), a member of the family Arenaviridae .
