What is Meningitis?
The medical terminology meaning for Meningitis is inflammation of the meninges. Meningitis is an inflammation of the membranes meninges surrounding your brain and spinal cord. The infection occurs most often in children, teens, and young adults. Also at risk are older adults and people who have long-term health problems, such as a weakened immune system. Meningitis may be caused by many different viruses and bacteria. It can also be caused by diseases that can trigger inflammation of tissues of the body. Meningitis usually results from a viral infection, but the cause may also be a bacterial infection. Less commonly, a fungal infection may cause meningitis. Acute bacterial meningitis usually occurs when bacteria enter the bloodstream and migrate to the brain and spinal cord. But it can also occur when bacteria directly invade the meninges, as a result of an ear or sinus infection, or a skull fracture, or rarely, after some surgeries. For example the following bacterias; Streptococcus pneumonia, Haemophilus influenza, Neisseria meningitides, and Listeria monocytogene.
There are two main kinds of meningitis:
* Viral meningitis is fairly common. It usually doesn't cause serious illness. In severe cases, it can cause prolonged fever and seizures.
* Bacterial meningitis isn't as common, but it's very serious. It needs to be treated right away to prevent brain damage and death.
Viral meningitis is caused by viruses. Bacterial meningitis is caused by bacteria. Meningitis can also be caused by other organisms and some medicines, but this is rare. Meningitis is contagious. The germs that cause it can be passed from one person to another through coughing and sneezing and through close contact.
The most common symptoms among teens and young adults are:
* A stiff and painful neck, especially when you try to touch your chin to your chest.
