Most infections are asymptomatic; a small number cause a minor illness that is indistinguishable from many other viral illnesses; less than 1% result in acute flaccid paralysis. This article lists people who had the paralytic form of polio. The extent of paralysis varies from part of a limb to quadriplegia and respiratory failure.
LOS ANGELES (AP) - A small number of children in California have been afflicted with polio-like illnesses that led to paralysis in one or more limbs. The Los Angeles Times reports that state ...
Non-polio enteroviruses, like EV-D68, cause about 10 to 15 million infections and tens of thousands of hospitalizations each year across the US. EV-D68 was first identified in California in the ...
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.
Poliomyelitis (/ ˌ p oʊ l i oʊ ˌ m aɪ ə ˈ l aɪ t ɪ s / POH-lee-oh-MY-ə-LY-tiss), commonly shortened to polio, is an infectious disease caused by the poliovirus. [1] Approximately 75% of cases are asymptomatic; [5] mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.
Enterovirus D68, which in rare cases can cause polio-like paralysis in children, is on the rise in California and across the nation, analyses show.
Polio-like syndrome is a general description of a group of symptoms which mimic polio, including rarely permanent paralysis. Various triggers have been found, including some viruses from the same virus group as polio: enterovirus 68, enterovirus 71, and coxsackievirus A7. [1] [2] These are suspected in many cases of acute flaccid myelitis.
Rows of iron lungs filled hospital wards at the height of the polio outbreaks of the 1940s and 1950s, helping children, and some adults, with bulbar polio and bulbospinal polio. A polio patient with a paralyzed diaphragm would typically spend two weeks inside an iron lung while recovering. [36] [37]
