No thanksMeningitis is an infection of the fluid in the spinal cord and the fluid that surrounds the brain. Meningitis is usually caused by an infection of a virus or bacteria. Knowing whether meningitis is caused by a virus or a bacteria is important because of differences in the seriousness of the illness and the treatment needed. Bacterial meningitis can be contagious, and illness can be severe. Viral meningitis is usually a mild illness. It is fairly common and is found worldwide.
Viral meningitis is caused by any of a number of different viruses, many of which are related to other diseases. About half of the cases are caused by common intestinal viruses. Occasionally, children with mumps or herpes virus infection develop viral meningitis. In many cases, a specific virus cannot be identified.
Usually within one week of exposure. Illness lasts less than 10 days, and people usually recover completely without complications.
The way people get infected with viral meningitis depends on the virus involved. Some viruses are shed in the stool of people while others are spread through respiratory droplets from the nose and throat. Most people are exposed to these viruses at some time in their lives, but very few people ever develop meningitis. Children and young adults are at higher risk of contracting viral meningitis.
The diagnosis is usually made by a blood test or by taking a sample of spinal fluid in which a needle is inserted into an area in the lower back. Results may identify the type virus.
No specific treatment is available. Antibiotics do not work against viruses. Viral meningitis clears up in a week or two. However, persons with symptoms should seek medical attention.
Cleaning your hands is the most effective way to prevent the spread of germs. Regular hand cleaning with either soap and water, or an alcohol based hand sanitizer will reduce the risk of getting sick for both children and adults.
