Poliovirus discovered in London's sewer system

London's sewerage system has recently detected the presence of the poliovirus, which experts fear could lead to a resurgence of polio in the UK - the polio vaccine is given to children in the UK (and around the world) so there The population is generally polio-free - but as a result of anti-vaccine lobby propaganda in the last few years, many parents do not vaccinate their children at all, which makes it possible for a portion of the population to be vaccinated against polio. Can be infected with a virus.  

  Why is the sewerage system monitored?

Many steps are being taken in many developed countries to control the coronavirus epidemic - where corona tests are now available in many places and many governments are providing free corona test kits to people at home. The city's sewerage system is also being monitored - scientists take water samples from the sewerage system and track the presence of various viruses and bacteria in them - as soon as possible in which neighborhood the coronavirus is spreading. Detection is done by sampling sewage water. By taking sewage water samples from different places in the same area, experts can quickly find out from which part of the street the coronavirus is entering the sewage system. The corona test of the people in the area immediately reveals where the virus is present in the house - the occupants of the house and the surrounding neighborhood can be given a dose of the vaccine and the infected person is instructed to quarantine. In order to prevent the virus from spreading further, a similar sampling revealed the presence of the poliovirus in London's sewerage system.

 How did the poliovirus reach London?

Experts do not know the answer to this question at the moment - but they estimate that the poliovirus has reached London from a person who went to London from Pakistan or Afghanistan in a state that he had a polio infection in his body. Polio has now been eradicated from all over the world except Pakistan and Afghanistan. The poliovirus, like other parts of the body, makes copies in the stomach and intestines and is excreted in the feces. Poliovirus in developing countries, It is usually spread by waste - especially in Pakistan and Afghanistan. Since we clean our hands after we have finished our work, the virus can spread to our hands. Washing leaves a virus on the hands that can be transmitted to other people - this is called fecal-oral transmission - in Pakistan and Afghanistan children are vaccinated so that the vaccine reaches the digestive tract directly and there're Do to let any virus get in the way - In Western countries, the polio vaccine that is given by injection is fecal-oral. Does not have much effect against nasal congestion.

The presence of the poliovirus in London's sewerage system is a sign that more than one person in London has the poliovirus and that the virus is circulating in the local population - experts are urging the public to If children are not vaccinated against polio, they should be vaccinated immediately so that the poliovirus does not spread - especially since London is an international city where people from all over the world come and go. It's feared that the virus may spread from London to the rest of the world.

 Why is polio vaccine free in Pakistan?

Smallpox has already eradicated from the world thanks to a similar international campaign - the smallpox virus, like polio, can neither survive outside the human body nor make copies in any other animal. The polio eradication campaign, designed in the style of a successful smallpox campaign. At the time of the smallpox eradication, there was no social media or conspiracy theories in the world, so the anti-smallpox campaign was very successful. And smallpox was eradicated from the world in 1980 - but unfortunately there was a lot of propaganda on social media and print media against the polio campaign which continues to this day - so the campaign against polio has not been successful yet and Pakistan And new polio cases still being discovered in Afghanistan.

The Coronavirus has cost the world economy 8.5 trillion - a major cause of the current global economic crisis, which is being felt in Pakistan as well. Corona could have been prevented before it became a pandemic if governments around the world had already provided funding for epidemic prevention on a priority basis. Less than a percent - Funds for polio eradication also being given because if polio starts to spread again in the world, it will cost many times more to prevent it.
