The critical nerves affected are the phrenic nerve (which drives the diaphragm to inflate the lungs) and those that drive the muscles needed for swallowing. By destroying these nerves, this form of polio affects breathing, making it difficult or impossible for the patient to breathe without the support of a ventilator. It can lead to paralysis ...
A doctor and professor explains how we have forgotten the contagious and painful symptoms of Polio. Why We Need to Remember the Physical Effects of Polio Skip to main content
Poliovirus is, however, strictly a human pathogen, and does not naturally infect any other species (although chimpanzees and Old World monkeys can be experimentally infected). [40] The CD155 gene appears to have been subject to positive selection. [41] The protein has several domains of which domain D1 contains the polio virus binding site.
Post-polio syndrome (PPS, poliomyelitis sequelae) is a group of latent symptoms of poliomyelitis (polio), occurring in more than 80% of polio infections. The symptoms are caused by the damaging effects of the viral infection on the nervous system and typically occur 15 to 30 years after an initial acute paralytic attack.
Polio is an infection caused by a virus that mostly affects children under 5. Most people infected with polio don’t have any symptoms, but it can cause fever, headaches, vomiting and stiffness ...
In extreme cases polio can cause paralysis, usually in the legs, although movement typically comes back within a few weeks or months. However, it can be life-threatening if it paralyses the ...
The white space represents a disruption of the nerve fibers, resulting in a loss of nerve supply to the muscle fibers. Denervation is any loss of nerve supply regardless of the cause. If the nerves lost to denervation are part of neural communication to an organ system or for a specific tissue function, alterations to or compromise of ...
The recent New York patient was infected with vaccine-derived polio, a strain linked to live virus from an oral polio vaccine not administered in the U.S. It marks the first U.S. of vaccine ...
