Meningitis occurs in people of all ages, but infants, young children and the elderly are more likely meningitis. Definition Meningitis is an infection of the membranes covering the brain and spinal cord. Recurrent benign lymphocytic meningitis is a recurring, typically innocuous, painful form of aseptic meningitis. Viral meningitis is the most common type of meningitis in the United Kingdom but it is often not talked about as much as, thankfully, it doesn’t kill people or harm people in the same way as bacterial meningitis. Herpes simplex viruses (HSV) are neurotropic viruses that are frequent human pathogens . HSV encephalitis is mainly caused by HSV-1, whereas meningitis is more often caused by HSV-2. This article explains a few things about meningitis, and if you’re interested, then this is worth reading, because you can never tell what you do not know.
Meningitis is inflammation of the membranes (called meninges) surrounding the brain and the spinal cord. It also may be caused by a fungal infection, parasite, a reaction to certain medications or medical treatments, a rheumatologic disease such as lupus, some types of cancer, or a traumatic injury to the head or spine.

Description: Clinical Infectious Diseases publishes clinically relevant articles on the pathogenesis, clinical investigation, medical microbiology, diagnosis, immune mechanisms, and treatment of diseases caused by infectious agents. Most cases of viral meningitis are relatively mild, with symptoms of headache, fever and general ill feeling, and those affected recover without medical treatment. A survey found that 67% of respondents did not know that herpes viruses can cause a severe inflammation of the central nervous system, called meningitis. Herpes simplex viruses (HSV) are neurotropic viruses that are frequent human pathogens .
Severe headache is the most common symptom of meningitis (87 percent) followed by nuchal rigidity (“neck stiffness”, found in 83%). Herpes viruses are the other common cause of viral meningitis in adolescents and adults in developed countries2. Read about the main causes of meningitis and how the infection is spread. Infectious forms of encephalitis are contagious. HSV viruses have been linked to Recurrent Lymphocytic Meningitis, also known as Mollaret’s meningitis. Meningitis can be caused by viruses or bacteria. Aseptic meningitis is an illness that appears similar to bacterial meningitis ; however , bacteria do not grow in cultures of the fluid around the brain and spinal cord -LRB- cerebrospinal fluid -RRB- .See also : MeningitisMeningitis – cryptococcalMeningitis – gram – negativeMeningitis – H.
Vaccination programmes have helped reduce the number of different types of bacteria that can cause meningitis. Viral MeningitisBackClinical PresentationHistoryPhysical ExaminationBackground Viral meningitis is inflammation of the leptomeninges as a manifestation of central nervous system (CNS) infection. Although uncomfortable, viral meningitis almost never leads to serious sequelae. this may not be available in the emergency setting so a CT scan is usually performed first in very ill individuals. Video Topic : This 3D medical animation depicts the anatomy and the layers of the meninges that cover the brain and spinal cord. The only symptom may be a dimple or a tuft of hair on the skin over the spine. Unlike herpes bumps which come and go, genital warts are persistent.
What is Meningitis? In most cases, the causes of meningitis are infections from a virus, bacteria or fungus. *Corresponding author: Alijan Tabarraei, Department of Microbiology, Infectious Diseases Research Centre, Golestan University of Medical Sciences, Gorgan, IR Iran. There are various types of Meningitis . Acute bacterial meningitis is rapidly developing inflammation of the layers of tissue that cover the brain and spinal cord (meninges) and of the fluid-filled space between the meninges (subarachnoid space) when it is caused by bacteria. Abstract Cryptococcus neoformans and Herpes simplex virus (HSV) are known agents of fungal and viral meningitis, respectively, in immunocompromised patients but rarely seen in immunocompetent patients. 5 weeks prior to being struck by this illness I had a tooth taken out.
Meningitis is an infection of the fluid of a person’s spinal cord and the fluid that surrounds the brain. Viral meningitis is the most common form. The symptoms of viral meningitis are usually milder than those associated with bacterial meningitis and may begin with flu-like symptoms. The cause of aseptic meningitis in one patient with recurrent dermatomal skin lesions was shown to be HSV-2.16 PCR has also revealed that the primary agent causing benign recurrent lymphocytic meningitis is HSV-2. Encephalomyelitis is inflammation of both the brain and spinal cord. Meningitis is an inflammation on the brain and spinal cord lining, and can be quite a serious illness. The symptoms of meningitis may resemble other problems or medical conditions.
HSV1 is the causative agent of encephalitis, corneal blindness, and several disorders of the peripheral nervous system; HSV2 is responsible for meningoencephalitis in neonates and meningitis in adults.
