The severe symptoms can

vision loss, numbness and
paralysis. These symptoms
may last several weeks,
and neurological effects
may be permanent.

Symptoms in Some People. Up
to 20 percent of the people
who become infected will
display symptoms which
can include fever, headache
and body aches, nausea,
vomiting, and sometimes
swollen lymph glands or
a skin rash on the chest,
stomach and back. Symptoms
can last for as short as
a few days, though even
healthy people have been
sick for several weeks.

- No
Symptoms in Most People. Approximately
80 percent of people (about
4 out of 5) who are infected
