Meningitis (pl.meningitides) is acute or chronic inflammation of the protective membranes covering the brain and spinal cord, collectively called the meninges. The most common symptoms are fever, intense headache, vomiting, neck stiffness, and occasionally photophobia. Other symptoms include confusion or altered consciousness, nausea, and an inability to tolerate loud noises. Young children often exhibit only nonspecific symptoms, such as irritability, drowsiness, or poor feeding. A non-blanching rash (a rash that does not fade when a glass is rolled over it) may also be present.

In the present book, ten typical literatures about meningitis published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on meningitis. We hope this book can demonstrate advances in meningitis as well as give references to the researchers, students and other related people.
