The first case of polio has been reported in New York, the first in the United States in almost 10 years..Health officials did not detail the Rockland County resident’s medical condition. Rockland County is about an hour and-a-half north of New York City..Officials said the patient was infected with a strain of the poliovirus derived from a version of the polio vaccine itself. The viral infection would have been transmitted from someone who’d received a live-attenuated version of the polio vaccine. These versions are available in other countries, but not the US..Some vaccines use a live virus antigen or an attenuated (weakened) version of the virus in their manufacture..“The live attenuated strains used in the oral poliovirus (OPV) have been the main tool in the WHO polio eradication program,” a study on the PubMed.gov website said.."However, these strains replicate in the human gut and are excreted for several weeks after immunization. During this period, the attenuating mutations in the vaccine strains can rapidly revert. This may, in rare cases, cause vaccine-associated paralytic poliomyelitis (VAPP) in vaccinees, or result in transmissible and neurovirulent circulating vaccine-derived poliovirus (cVDPV) strains,..Once upon a time, polio was one of America and Europe’s most feared diseases. Yearly outbreaks would cause thousands of cases of paralysis — many of them in children..Polio was considered eliminated in the US by 1979 and spread was reported to have stopped. The last case of a traveller to the US bringing in polio was in 2013..New York State’s Health Department identified the case at its public health laboratory and confirmed the diagnosis with the Centers for Disease Control and Prevention (CDC)..Health officials scheduled vaccination clinics nearby for Friday and Monday, and are asking people to consider getting a shot if they haven’t already had one..“We want shots in the arms of those who need it,” a health spokesperson said at the Thursday press conference where the case was announced..Polio spreads mostly from person-to-person or via contaminated water. It can infect a person’s spinal cord, causing paralysis and can, although rare, cause permanent disability and death..Polio is endemic in Afghanistan, and Pakistan, although numerous countries in Africa, the Middle East Asia have also reported cases in recent years..Last month, health officials in Britain warned parents to make sure children have been vaccinated because the poliovirus had been found in London sewage samples. There were no cases of paralysis reported..READ MORE: Polio is back after 40 years and the UK government declares a national incident.Polio is a viral disease that can affect the nervous system and cause muscle weakness..Symptoms can be mild and flu-like and can take up to 30 days to appear, making time for infected individuals to spread the virus to others..A condition closely associated with poliomyelitis, called non-polio acute flaccid paralysis (NPAFP), surfaced where the vaccine-derived version of the poliovirus is in circulation, Indian researchers report. NPAFP is clinically indistinguishable from polio paralysis, but twice as deadly.
