Reye's Syndrome is a disease which affects all organs of the body, but most lethally the
liver and the brain. Reye's Syndrome is a two-phase illness because it is almost always
associated with a previous viral infection, such as influenza, cold, or chicken pox.
Scientists do know that Reye's Syndrome is not contagious and the cause is unknown.
Reye's Syndrome is often misdiagnosed as encephalitis, meningitis, diabetes, drug
overdose, poisoning, Sudden Infant Death Syndrome, or psychiatric illness. It is
associated with the use of aspirin in children to treat chickenpox or influenza.
