Many different viruses can cause meningitis. This process is likely initiated by the ligation of the bacterial components eg, peptidoglycan and lipopolysaccharide to pattern-recognition receptors, such as the Toll-like receptors TLRs.
Meningeal seeding may also occur with a direct bacterial inoculate during trauma, neurosurgery, or instrumentation. The bacteria that cause meningitis can spread when people who are Viral meningitis cough or sneeze. Eventually, if this uncontrolled process is not modulated by effective treatment, transient neuronal dysfunction Viral meningitis permanent neuronal injury results.
Some of them may also cause stomach upsets and diarrhoea. In Viral meningitis severe forms, the pial barrier is not penetrated, and the underlying parenchyma remains intact. Coxsackie virus and echovirus, two members of a family of viruses called enteroviruses, account for about half the cases of aseptic meningitis.
It can be life-threatening or lead to brain damage without quick treatment. People who develop severe illness, or at risk for developing severe illness, such as babies, and people with weakened immune systems may need to be hospitalized.
Consultation with a neurosurgeon is indicated; early shunt removal is usually necessary for cure. Most meningeal pathogens are transmitted through the respiratory route, including Neisseria meningitidis meningococcus and S pneumoniae pneumococcus.
The most common causes are: Some behavioral measures may also be effective. The fungi usually responsible are Cryptococcus, which can be inhaled from bird droppings, and Histoplasma, found in bird or bat droppings.
In many cases, this contributes to vasogenic edema and elevated CSF protein levels. It is characterised by sudden attacks of meningitis symptoms that usually last for days and are separated by symptom free intervals lasting for weeks,months or years.
The bacteria then travel through the bloodstream to the brain. Cryptococcal meningitis is a common fungal form of the disease that affects people with immune deficiencies, such as AIDS.
It is very important to see a healthcare provider right away if you think you or your child might have Viral meningitis. College students living in dormitories, personnel on military bases, and children in boarding schools and child care facilities are at greater risk of meningococcal meningitis.
The sample of CSF will be examined and then sent for further laboratory testing. HSVs can cause meningitis or encephalitis inflammation of the brain itself, which is much more serious. There are a number of viruses that can trigger the disease, including several that can cause diarrhea.Viral meningitis information including symptoms, diagnosis, misdiagnosis, treatment, causes, patient stories, videos, forums, prevention, and prognosis.
Viral infections are the most common cause of meningitis, followed by bacterial infections and, rarely, fungal infections. Because bacterial infections can be life-threatening, identifying the cause is essential.
Meningitis is an inflammation (swelling) of the protective membranes covering the brain and spinal cord. A bacterial or viral infection of the fluid surrounding the brain and spinal cord usually causes the swelling. Spinal Meningitis Occurs in Both Children and Adults.
Viral Meningitis is milder and far more common vs the significantly more serious bacterial meningitis disease variation. This section will give you some more information on some of the terms and descriptions used in this site.
Amoebic meningitis. Amoebic meningitis is a very rare infection caught from stagnant water in waterholes and in poorly chlorinated swimming pools, especially when the water temperature rises above 30 degrees Celsius (86 degrees Fahrenheit).
If my baby has meningitis, how do I know how serious it is? Only a doctor can tell you how serious it is, as the symptoms for viral and bacterial meningitis are very similar.Download
