Poliomyelitis. Polio (poliomyelitis) mainly affects children under 5 years of age. One in 200 infections leads to irreversible paralysis. Among those paralysed, 5–10% die when their breathing muscles become immobilized. Cases due to wild poliovirus have decreased by over 99% since 1988, from an estimated 350 000 cases in more than 125 endemic ...
Poliomyelitis (polio) is a highly infectious viral disease that largely affects children under 5 years of age. The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (e.g. contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and cause paralysis.
Oral polio vaccine (OPV) contains an attenuated (weakened) vaccine-virus, activating an immune response in the body. When a child is immunized with OPV, the weakened vaccine-virus replicates in the intestine for a limited period, thereby developing immunity by building up antibodies. During this time, the vaccine-virus is also excreted.
Polio vaccine, given multiple times, almost always protects a child for life. The development of effective vaccines to prevent paralytic polio was one of the major medical breakthroughs of the 20th century. There are six different vaccines to stop polio transmission: Inactivated polio vaccine (IPV) – protects against poliovirus types 1, 2, and 3
Poliomyelitis (polio) Poliomyelitis (polio) is a highly infectious and sometimes fatal disease caused by a virus. It invades the nervous system and can cause irreversible paralysis. The disease usually affects children under five years of age. Polio cannot be cured, but there are safe vaccines that can effectively prevent the disease.
Polio does still exist, although polio cases have decreased by over 99% since 1988, from an estimated more than 350 000 cases to 22 reported cases in 2017. This reduction is the result of the global effort to eradicate the disease. Today, only 2 countries in the world have never stopped transmission of polio (Pakistan and Afghanistan).
Since 2000, the Western Pacific Region has maintained polio-free status. Poliomyelitis is a highly infectious disease caused by a poliovirus. It mainly affects children under 5 years of age but also can affect older age groups. Polioviruses are spread by faecal-to-oral and oral-to-oral transmission. Lack of access to clean water and adequate sanitation is a major risk factor for transmission.
Children in Gaza are now at risk of polio as well as bombs – we need a ceasefire now. Originally published in The Guardian on 26 July 2024. The polio virus was detected in wastewater samples in Gaza last week, an alarming yet unsurprising development given the dismantled state of the territory’s health systems after nine relentless months ...
Health advisories including information on polio, the situation in New York State, and polio immunization, have been released to health providers and hospitals across the State and in the immediate county of residence of the case. On 9 September, a state disaster emergency due to polio was declared in New York State.
Poliomyelitis is an acute communicable disease of humans caused by a human enterovirus of the Picornaviridae family. The virus is composed of a single-stranded, positive-sense RNA genome and a protein capsid. The 3 serotypes of poliovirus carry are antigenically distinct. Poliovirus is transmitted from one person to another by oral contact with ...
