There is a risk for aseptic meningitis, encephalitis, and hemorrhagic fever, but these complications are extremely rare.

Encephalitis is an inflammation (irritation and swelling) of the brain, usually caused by infections. See also meningitis.
|
|
Although the word meningitis suggests an inflammation of the meninges only, there is always some involvement of the most superficial parts of the brain that are contiguous to the meninges. Often there are also alterations in the flow of cerebrospinal fluid (CSF).

Encephalitis is an inflammation of the brain, usually caused by a direct viral infection or a hypersensitivity reaction to a virus or foreign protein. Brain inflammation caused by a bacterial infection is sometimes called cerebritis.
|
|
An inflammatory disease of the brain caused by a virus that either has invaded the brain, or a virus appearing elsewhere in the body that has caused a sensitivity reaction in the brain. Encephalitis infects the brain tissue itself and has serious consequences.

Encephalitis is an acute inflammatory process that affects brain tissue and is almost always accompanied by inflammation of the adjacent meninges (tissues lining the brain). There are many types of encephalitis, most of which are caused by viral infections.

Aseptic meningitis is an illness characterized by headache, fever, and inflammation of the lining of the brain (meninges. Although it looks like bacterial meningitis, bacteria do not grow in cultures of the cerebrospinal fluid (fluid around the brain and spinal cord.

The following Clinical Topic Tour provides an overview of meningitis and was adapted from materials published by the National Institute of Neurological Disorders and Stroke, the National Cancer Institute, and the Centers for Disease Control and Prevention (CDC).

Bacterial meningitis Epidemiology and microbiology: the overall annual incidence of bacterial meningitis is about 2?3/100,000, with peaks of incidence in infants and adolescents. Integration of vaccines into the UK vaccination programme against Haemophilus influenzae type b (Hib) and more recently against group C meningococccus has led to a marked decline in cases of Hib and Group C meningococcal meningitis and has significantly reduced the overall incidence of bacterial meningitis.

Meningitis is the most common serious manifestation of infection of the central nervous system (CNS). Inflammatory involvement of the subarachnoid space with meningeal irritation leads to the classic triad of headache, fever and meningism, and to a pleocytosis in the cerebrospinal fluid (CSF).
