PremierLeague-News.Com - Breaking Sport Transfer News ! UK health officials have declared a national incident after poliovirus was found in sewage samples in London. The UK Health Security Agency (UKHSA) says the risk for the public is low, but urges parents to ensure their kids are up to date with their polio vaccination. The UK was declared polio-free in 2003, with the last case of wild polio contracted here dating almost four decades back in 1984. Most people who catch the virus don't feel any symptoms, and a small number experience flu-like symptoms. But in rare cases the poliovirus attacks the nervous system and causes paralysis. There have been no reports so far of polio cases in the UK, but the concern is that the virus could gain a foothold in areas where polio vaccination rates are low. The UKHSA says that childhood vaccines have decreased nationally and especially in parts of London over the past few years.

The UKHSA says one-off findings of polioviruses each year are normal during routine surveillance of sewage. These occurrences are imported by someone who was recently vaccinated overseas with a live form of the virus. However, this time, there has been evidence the virus has continued to evolve as several genetically related viruses were found in samples taken between February and May. The sewage samples in question were collected from the London Beckton Sewage Treatment Works, which processes waste from 4 million people in north and east London. Investigations are now trying to establish if there's transmission in the community.

. Most of the developed countries have switched to IPV from OPV. The problem with the OVP is that the weakened poliovirus has the potential to change over time and behave more like the naturally occurring virus. This is called 'vaccine-derived' poliovirus. The virus found in London has is now classified as a ‘vaccine-derived’ poliovirus type 2 (VDPV2). This means that on rare occasions can cause serious illness, such as paralysis, in people who are not fully vaccinated. Because in extremely rare occasions the oral vaccine could either cause outbreaks of vaccine-derived poliovirus, or 'vaccine-associated paralytic polio (VAPP)', routine immunization with OPV must cease after the eradication of wild poliovirus, says the World Health Organisation and other authorities. How worried should we be? So far, no cases of polio or related paralysis have been reported in the UK and the risk to the public is "extremely low", experts say. However, people are urged to make sure that they and their children are up to date with their polio vaccinations, which are highly effective at protecting people protects against both naturally occurring polioviruses and vaccine-derived polioviruses. Dr Vanessa Saliba, Consultant Epidemiologist at UKHSA said: "Vaccine-derived poliovirus has the potential to spread, particularly in communities where vaccine uptake is lower. On rare occasions it can cause paralysis in people who are not fully vaccinated so if you or your child are not up to date with your polio vaccinations it’s important you contact your GP to catch up or if unsure check your Red Book. Most of the UK population will be protected from vaccination in childhood, but in some communities with low vaccine coverage, individuals may remain at risk."
