Polio virus wikipedia

Poliovirus, the causative agent of polio (also known as poliomyelitis), is a serotype of the species Enterovirus C, in the family of Picornaviridae.. Poliovirus is composed of an RNA genome and a protein capsid.The genome is a single-stranded positive-sense RNA (+ssRNA) genome that is about 7500 nucleotides long. The viral particle is about 30 nm in diameter with icosahedral symmetry The history of polio (poliomyelitis) infections began during prehistory.Although major polio epidemics were unknown before the 20th century, the disease has caused paralysis and death for much of human history. Over millennia, polio survived quietly as an endemic pathogen until the 1900s when major epidemics began to occur in Europe. Soon after, widespread epidemics appeared in the United States

Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. In about 0.5 percent of cases, it moves from the gut to affect the central nervous system and there is muscle weakness resulting in a flaccid paralysis. This can occur over a few hours to a few days. The weakness most often involves the legs, but may less commonly involve the muscles of the head. Poliomyelitis, or polio, is a virus that causes a serious disease.It is spread from person to person.. Most of the time, polio has no symptoms unless the polio virus gets into the blood. It is uncommon for the virus to enter the brain or spinal cord.If this does happen, it can cause muscles to become paralyzed.Some people get better from the paralysis Il poliovirus si replica per circa una settimana all'interno delle cellule gastrointestinali, da dove poi si diffonde alle tonsille (in particolare nelle cellule follicolari dendritiche che risiedono all'interno dei centri tonsillari germinali), al tessuto intestinale linfoide, comprese le cellule M delle placche di Peyer, alla linfa cervicale profonda e ai linfonodi mesenterici, dove si.

Poliovirus receptor-related 1 (PVRL1), also known as nectin-1 and CD111 (formerly herpesvirus entry mediator C, HVEC) is a human protein of the immunoglobulin superfamily (IgSF), also considered a member of the nectins. It is a membrane protein with three extracellular immunoglobulin domains, a single transmembrane helix and a cytoplasmic tail Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types are used: an inactivated poliovirus given by injection (IPV) and a weakened poliovirus given by mouth (OPV). The World Health Organization (WHO) recommends all children be fully vaccinated against polio. The two vaccines have eliminated polio from most of the world, and reduced the number of cases reported each year. Polio eradication, the permanent global cessation of circulation by the poliovirus and hence elimination of the poliomyelitis (polio) it causes, is the aim of a multinational public health effort begun in 1988, led by the World Health Organization (WHO), the United Nations Children's Fund (UNICEF) and the Rotary Foundation. These organizations, along with the U.S. Centers for Disease Control. Function. CD155 is a Type I transmembrane glycoprotein in the immunoglobulin superfamily. Commonly known as Poliovirus Receptor (PVR) due to its involvement in the cellular poliovirus infection in primates, CD155's normal cellular function is in the establishment of intercellular adherens junctions between epithelial cells. The role of CD155 in the immune system is unclear, though it may be. Il poliovirus è un microrganismo la cui trasmissione tra essere umano ed essere umano può avvenire: Per via oro-fecale ( trasmissione oro-fecale ). I medici parlano di trasmissione oro-fecale quando, complici misure igienico-sanitarie inadeguate, un agente patogeno passa, in qualche modo, dall' apparato digerente di una persona infetta all'apparato digerente di una persona sana

Inactivated poliovirus vaccine (IPV) given as an injection in the leg or arm, depending on the patient's age. Only IPV has been used in the United States since 2000. Oral poliovirus vaccine (OPV) is still used throughout much of the world. Polio vaccine protects children by preparing their bodies to fight the poliovirus Wild poliovirus cases have decreased by over 99% since 1988, from an estimated 350 000 cases in more than 125 endemic countries then, to 33 reported cases in 2018. Of the 3 strains of wild poliovirus (type 1, type 2, and type 3), wild poliovirus type 2 was eradicated in 1999 and no case of wild poliovirus type 3 has been found since the last reported case in Nigeria in November 2012 This means that there is no year-round transmission of poliovirus in the United States. Since 1979, no cases of polio have originated in the U.S. However, the virus has been brought into the country by travelers with polio. The last time this happened was in 1993 Polio is a very contagious infection that is caused by the poliovirus. Thanks to immunization, Canada has been polio free for the last 20 years.

It is initiated by binding of a poliovirion to the cell surface macromolecule CD155, which functions as the receptor (1). Uncoating of the viral RNA is mediated by receptor-dependent destabilization of the virus capsid (2) But poliovirus is still a threat in some countries. It takes only one traveler with polio to bring the disease into the United States. The best way to keep the United States polio-free is to maintain high immunity (protection) in the U.S. population against polio through vaccination

Wild poliovirus (WPV) is the most commonly known form of the poliovirus. However, there is another form of polio that can spread within communities: circulating vaccine-derived poliovirus, or cVDPV. While cVDPVs are rare, they have been increasing in recent years due to low immunization rates within communities. cVDPV type 2 (cVDPV2) are the most prevalent, with 959 cases occurring globally in.
