The most common causes of viral meningitis in the United States are non-polio enteroviruses. The viruses that cause meningitis are typically acquired from sick contacts. However, in most cases, people infected with viruses that may cause meningitis do not actually develop meningitis. [5] Viruses that can cause meningitis include: [17]
It can cause impairments to the cranial nerves, paralysis to the eyes, and sudden hearing loss. [ 8 ] [ 9 ] Meningoencephalitis is a rare, late-stage manifestation of tick-borne ricksettial diseases, such as RMSF and human monocytotropic ehrlichiosis (HME), caused by Ehrlichia chaffeensis (a species of rickettsiales bacteria).
As such, and because HSV is the most common cause of viral encephalitis, acyclovir is often administered as soon as possible to all patients suspected of having viral encephalitis even if the exact viral origin is not yet known. Viral resistance to acyclovir rarely occurs, primarily among the immunocompromised, in which case foscarnet should be ...
St. Louis encephalitis; Slow virus infections, which include: Acquired immunodeficiency syndrome (AIDS) Subacute sclerosing panencephalitis by Measles virus; Progressive multifocal leukoencephalopathy; Rabies; Tick-borne encephalitis; Varicella; Viral encephalitis lists 37 causes; Viral meningitis; Western equine encephalitis
It may identify bacteria in bacterial meningitis and may assist in distinguishing the various causes of viral meningitis (enterovirus, herpes simplex virus 2 and mumps in those not vaccinated for this). [22] Serology (identification of antibodies to viruses) may be useful in viral meningitis. [22]
Tick-borne encephalitis (TBE) is a viral infectious disease involving the central nervous system. The disease most often manifests as meningitis, encephalitis or meningoencephalitis. Myelitis and spinal paralysis also occurs. In about one third of cases sequelae, predominantly cognitive dysfunction, persist for a year or more. [1]
HSV-2 is the most common cause of Mollaret's meningitis, a type of recurrent viral meningitis. [6] This condition was first described in 1944 by French neurologist Pierre Mollaret. Recurrences usually last a few days or a few weeks, and resolve without treatment. They may recur weekly or monthly for approximately 5 years following primary ...
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] Other causes of acute viral encephalitis are ...
