In the Western world, viral encephalitis is the most common type of the disorder; it is typically caused by the herpes simplex virus.
In France, according to the published data, the incidence of encephalitis is estimated to an average of 1.9 case/100,000 inhabitants in non human immunodeficiency virus (HIV) patients.
One of the challenges of encephalitis is that agents are not found in most of the patients where up to 60%-85 60%-85tients are of unknown etiology.
Determining the etiology of encephalitis is difficult.
To the Editor: St . Louisencephalitis is a mosquito-borne viral disease that affects humans.
To the Editor: Acute encephalitis is rarely seen in patients infected with HIV (1 ).
The paraneoplastic limbic encephalitis is an unusual and hard to diagnose entity, which can easily be confused with psychiatric problems.
Only laboratory-confirmed encephalitis cases due to certain pathogens (e.g., Murray Valley encephalitis virus, Japanese encephalitis virus, or Australian bat lyssavirus) are notifiable to public health units; thus, the occurrence of encephalitis is not well documented.
The paraneoplastic limbic encephalitis is an unusual and hard to diagnose entity, which can easily be misdiagnosed as a psychiatric disorder.
The epidemiology of encephalitis is difficult to summarize since few population based studies exist, many causal pathogens are capable of inducing encephalitis-like symptoms and most cases go unreported to health authorities.
