UK Health Protection Agency (UKHSA) has identified a total of 116 PV2 isolates in 19 sewage samples collected in London between 8 February and 5 July this year, but most arevaccine virus and only a few have Mutations enough to be classified as Vaccine Poliovirus (VDPV2)”, The first alert for this virus came in June. “The levels and genetic diversity of poliovirus detected since then suggest that transmission is occurring in several London boroughs,” The organization has given this information in a statement.
,VDPV2 more worrisome because it behaves like more “wild” polio which occurs naturally and on rare occasions, causes cases of paralysis in illiterate people,” description.
As per Criterion DThe booster dose will be offered to the Joint Committee on Immunization and Immunization (JCVI) Inactivated Polio Vaccine (IPV) Because it will “ensure a high level of protection against paralysis and help reduce the spread of the virus”. Parents will be contacted by NHS London when it is their child’s turn polio booster dose, The agency insists that parents accept the “offer” as soon as possible.
Although no cases have been identified yet, the agency is planning a campaign with the intention of anticipating a possible outbreak. Thus, the health center will offer the booster vaccine to children aged one to nine years in areas of the city where the virus has been detected, and they plan to expand the age limit. Vaccination rates in London vary, but on average are below the 95 per cent coverage rate that the World Health Organization has suggested needs to be maintained polio under control
Poliomyelitis, spread primarily through contamination by fecal matter, has been used to kill and paralyze thousands of children worldwide annually. There is no cure, but vaccination has brought the world closer to eliminating the natural form of the disease. It paralyzes less than 1 percent of infected children.
After the case of polio in America
The virus found in the sewage of London is mainly vaccine-like virus, found when children vaccinated with a special type of live vaccine, now only used abroad, shed the virus in their feces. This harmless virus can transmitted between uninfected children and in doing so you can convert back to a more dangerous version of the virus and cause disease.
Last month, the United States found a case of paralytic polio outside New York uninfected person, the first in a decade. Earlier the British Health Agency reported that the case was genetically linked to the virus seen in London. In return, they have expanded surveillance. polio to other places outside London to see if the virus has spread further.
