Herpes simplex encephalitis (HSE), or simply herpes encephalitis, is encephalitis due to herpes simplex virus. 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.
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 ...
Many viral infections of the central nervous system occur in seasonal peaks or as epidemics, whereas others, such as herpes simplex encephalitis, are sporadic. In endemic areas it is mostly a disease of children, but as the disease spreads to new regions, or nonimmune travelers visit endemic regions, nonimmune adults are also affected. [5]
A potentially deadly mosquito-borne virus known to cause brain swelling has been detected in Florida, according to the state's health department. The disease, known as Eastern equine encephalitis ...
