Mainly gastrointestinal upset and sore throat. Poliovirus can be isolated from throat washings and stools. Interpretation: Poliovirus growing in gut and throat lymphatic tissue and has not migrated to the spinal cord or brain. Post-polio syndrome would be unlikely in these cases because of the lack of neurological involvement to any appreciable extent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Non-paralytic polio<\/strong>: Symptoms include neurological symptoms: Headache, stiff neck, muscle stiffness and spasms along with other muscular symptoms. Muscle strength testing at this time and after fever breaks does not show weakness, however, there is probably undetectable permanent nerve damage to some extent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Paralytic polio<\/strong>: All of the above symptoms additional residual weakness and lingering paralysis of some muscles. This is further classified depending on the area of the body where the most damage was clinically evident.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Spinal polio<\/strong>: where paralysis involves the skeletal muscles supplied by the spinal nerves.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bulbar polio<\/strong>: where there is the involvement of the muscles supplied by the cranial nerves. This type was seen in about 5 to 35% of cases (depending on the epidemic and led to problems of breathing, swallowing and speech).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Spinal\/Bulbar polio<\/strong>: where both areas of the body were affected.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>There are four stages to being a polio survivor:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1. <strong>Polio<\/strong>\u00a0\u2013 The time when you are infected by the polio virus<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. <strong>Recovery<\/strong>\u00a0\u2013 The time when you are recovered to your best ability<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3. <strong>Stable<\/strong>\u00a0<strong>period<\/strong>\u00a0\u2013 A stable period of function between 10 and 50 years<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4. <strong>New<\/strong>\u00a0<strong>symptoms<\/strong>\u00a0\u2013 Experienced by some polio survivors most commonly termed post-polio syndrome (PPS). See below for criteria for diagnosis.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">The following two facts about the level of nerve damage at the time of polio are important to take into consideration:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A. The first descriptions in medical literature appeared in 1875&nbsp;<\/strong>when 4 case histories were reported in the French literature by Carriere, Raymond, and Cornhill &amp; Lepine. Their patients, all young men, had paralytic polio in infancy and developed new weakness not only in previously affected muscles but also in muscles not believed to have been involved. They all had physically demanding jobs and performed repetitive activities.&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/poliosurvivorsnetwork.org.uk\/enter\/wp-content\/uploads\/2018\/10\/Health-and-Demographic-Characteristics-of-Polio-Survivors.pdf\" target=\"_blank\">Click here to view the full article<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>B. Professor WJW Sharrard in 1955&nbsp;<\/strong>reported that \u2018Motor cell destruction was always much more severe than would have been expected.\u2019 One case in which there had never been any demonstrable weakness in any muscle in the lower limbs had suffered losses of up to 40 per cent of the normal number of cells in some cell columns.&nbsp;&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/poliosurvivorsnetwork.org.uk\/enter\/wp-content\/uploads\/2018\/10\/Lincolnshire-Post-Polio-Library-The-Di...is-in-the-Lower-Limb-in-Poliomyelitis.pdf\" target=\"_blank\">Click here to view the full article<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These demonstrate that there were considerable levels of damage below which weakness was not clinically evident at the time of the diagnostic examination and that it is possible for polio survivors to have new issues in areas of their bodies previously not affected by weakness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is&nbsp;<em>NO<\/em>&nbsp;set pattern of nerve damage. Damage to the nerves from the virus varies in level and area(s) of the body. Dr. Marinos Dalakas likened it to standing polio survivors in front of a white sheet, throwing a bucket of black paint at them and at the same time hitting a wind machine with millions of settings, a different one for each person. The poliovirus having no set pattern of damage to the body makes it much more challenging for health professionals.&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/poliosurvivorsnetwork.org.uk\/enter\/wp-content\/uploads\/2018\/10\/lincpin55.pdf\" target=\"_blank\">See the cover of Newsletter Volume 5 Issue 5<\/a><\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity aligncenter\"\/>\n\n\n\n<h2 class=\"wp-block-heading has-text-color\" style=\"color:#3e7d98\"><strong>Recovery<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Simply, a muscle has a number of nerves supplying it to work. The poliovirus kills and damages nerves and the resulting ability depends on the numbers remaining. Recovery was possible because nerves that were not affected grew extra (axonally sprouted) nerve endings that re-innervated some muscle fibres that had lost their nerve supply.
