Repeated positive findings on polio indicate there is still a disease in the region and that it is likely to spread . This is strange considering that the United Kingdom has been declared polio-free since 2003 .
Birmingham, United Kingdom: The UK Health Security Agency (UKHSA) has reported a national epidemic of repeated poliovirus detection in sewage in north and east London, just as we predicted monkeypox would be the new virus epidemic for 2022.Repeated positive findings on polio indicate that there is still a disease in the region and that it is likely to spread.This is strange considering that the United Kingdom has been declared polio-free since 2003.Here's what you need to hear about it:Poliomyelitis (polio) is a rare disease that has caused paralysis and death around the world.We are getting closer to meeting this target each year, thanks to effective vaccination programs.There are three types of poliovirus, and one type of infection or immunization does not shield against another.Type 1 poliovirus has continued to erupt, but vaccination has successfully prevented transmission by types 2 and 3.Poliovirus is best spread by respiratory droplets, but it can be spread by food or water that has been in contact with the virus's faeces.It can also be spread by mosquito bites. Afghanistan and Pakistan are the only two countries where wild polio is still widespread, and they are regulated by vaccine reform to stop the virus from spreading to other countries.There were only about 700 cases identified in the United Kingdom in 2021.The injected polio vaccine is used in the United Kingdom.It contains an inactivated virus (IPV), and is safe and effective in defending the immunised individual from paralysis, but it is less effective at boosting local immunity in the gut, so immunized individuals can also become infected and shed infectious virus, although they may not show symptoms themselves.IPV provides excellent protection for the individual, but it is not enough to prevent an epidemic in the case of poor sanitation. OPV is administered by drops and does not need skilled personnel or sterile equipment to be administered, ensuring that it can reach more communities.This vaccine also has a potent gut immune system, which prevents the transmission of wild polioviruses.Since it contains a live virus, it can spread to close to the immunised individual's contacts and shield them as well.It is also cheaper than IPV.The drawback of using OPV is that the weakened virus will mutate and, in rare cases, revert to paralysis-causing variants.OVP is cleared by our immune system within days, but this may not be the case with people with weakened immune systems that carry the virus longer.This can lead to the transmission of the vaccine-derived poliovirus (VDPV) in under-immunized countries. In the United Kingdom, there is no wild poliovirus, and it is spread in faeces in people who have been vaccinated with IPV.Because there is no local gut protection with IPV, vaccine-derived polio can cause asymptomatic illness.It can be detected in sewage sewers, however, a single positive reading might not raise the alarm.In Kolkata, a type 1 VDPV was recently detected in sewage. There are no documented instances of polio-related paralysis in the United Kingdom.To prevent disease, we must make sure that family members are up to date with their vaccinations, especially children who have skipped a course of vaccination due to the COVID epidemic.To help prevent polio, the IPV is safe, free, and efficient.IPV is readily available to anyone in the United Kingdom through their GP, rather than being out of stock and only available to high-risk groups.
