Polio (vaccine-preventable)


Polio is an ancient scourge that became vaccine-preventable in the 1950's.Transmission of wild poliovirus was interrupted in the United States in 1979, or possibly earlier. A polio eradication program conducted by the Pan American Health Organization led to elimination of polio in the Western Hemisphere in 1991. The Global Polio Eradication Program has dramatically reduced poliovirus transmission throughout the world. 
 
When symptomatic, polio causes paralysis of the muscles. Most people never completely recover. Luckily, however, up to 95% of all polio infections occur without symptoms. Infected persons without symptoms shed viruses in the stool, and are thus able to spread the virus to others. Childhood immunization is recommended.


Disease Reporting

 
Health care providers and clinical laboratories are required by law to report cases and suspect cases of polio to local health departments immediately, day or night, after identification. Call 971-673-1111 to reach the state health department doctor on call.
