Meningitis is an acute contagious disease causing inflammation of the outer covering of the brain (meninges) and upper spinal column. The two primary kinds of meningitis are viral and bacterial, but it may be caused by other microorganisms including fungal, and parasitic. Meningitis may also be caused by other diseases, like Lyme disease that can affect the lining of the brain.
Ebola virus is an uncommon viral infection which kills nearly 90% of its victims. Researchers from National Institutes of Health (NIH), have identified five types of Ebola virus and discovered something in the virus that causes the significant internal bleeding that almost always results in death. The viral glycoprotein is believed to destroy endothelial cells that line the walls of the blood vessels.
