Polio
A contagious viral disease that can invade the nervous system.
Symptoms and what to notice
Most have no symptoms; some develop fever, fatigue, nausea, headache, stiff neck, or limb pain. Paralysis can occur.
How long can it last?
Minor illness lasts days; weakness or paralysis may be permanent, and post-polio syndrome can appear decades later.
How serious is Polio?
Paralytic polio can cause permanent disability or death when breathing muscles are affected.
Treatment and management
No cure; treatment is supportive and may include respiratory support and rehabilitation.
Is there a vaccine—and who should receive it?
U.S. children routinely receive four IPV doses at 2 months, 4 months, 6–18 months, and 4–6 years. Adults at increased risk may need vaccination or a booster.
