POLIO PROGNOSIS |
|
|
|
When poliovirus causes only the
minor illness or simple aseptic meningitis, the patient can be
expected to recover completely. When the patientis diagnosed with
the major illness, about 50% will recover completely. About 25% of
such patients will have slight disability, and about 25% will have
permanent and serious disability. Approximately 1% of all patients
with major illness die. The greatest return of muscle function
occurs in the first six months, but improvements may continue for
two years.
A recently described phenomenon
called post-polio syndrome may begin many years after the initial
illness. This syndrome is characterized by a very slow, gradual
decrease in muscle strength. |
