It is a highly infectious disease, which is transmitted mainly through the fecal oral route and less frequently through contaminated water or food.[1][2] Virus transmission is correlated with areas where water quality, sanitation and hygiene are poor.[3] The virus enters through the human gastrointestinal tract and proliferates in the intestines. Some of the initial symptoms of infection include: fever, malaise, headache, vomiting, nuchal rigidity, and pain in the limbs. The poliomyelitis virus can possibly even invade the nervous system and cause paralysis; this occurs in approximately one in two hundred infections.[4]
Polio reached the height of its pandemic proportions in the first half of the nineteenth century.[2] The creation of the first safe and effective poliovirus vaccine by Dr. Jonas Salk in 1955 made immediate and profound impacts in the incidence of disease. For example, in the United States two years prior to the development of the vaccine, the average number of polio cases was greater than 45,000. In 1962, just seven years after the advent of vaccination, that number diminished to 910.[2] The effectiveness of the vaccine soon prompted health officials to extend the application of immunization worldwide.
