After the presence of poliovirus in the drainage system, it has been decided to vaccinate all children aged 1 to 9 years in the British capital London.
The UK Health Security Agency has announced a new vaccine booster program to protect children against polio.
The UK Health Security Agency said 116 polioviruses had been identified in 19 samples of sewage from the northeast and central London since February.
Experts say that it is not clear how many people have been infected by this virus, but no case of polio has been reported so far.
But keeping in mind the spread of the virus in the population, the authorities have decided to administer an additional dose of polio vaccine in the next 4 to 6 weeks to protect children from this crippling disease.
Parents are advised to take their children to the doctor and get them vaccinated.
According to experts, the vast majority of the population has been vaccinated against polio and the risk of the disease is very low, but the polio virus is spreading in parts of London where vaccination rates are low.
He said that this is the reason why the virus is spreading in the population and people who are not vaccinated are facing more risk.
Although some amount of poliovirus is detected in sewage systems every year, there has been an unusual increase in the amount in recent months, indicating its spread within the population.
It should be noted that in June a national emergency was imposed in Great Britain after evidence of the spread of the polio virus.
Authorities believe the spread of the virus would start with someone returning to the UK from a country where they had received the oral polio vaccine.
Britain was declared polio-free in 2003, with the last case reported there in 1984.
Poliovirus is spread through poor hand hygiene, contaminated water, and food, but is also sometimes transmitted from person to person through coughing and sneezing
