Monitoring of the “polio” virus in London’s waterways


The almost complete eradication of polio is one of the achievements of the world’s health system during the past century, and for this reason, the recent monitoring of new cases of the disease in the British capital, London, is causing concern among doctors.

The British health authorities detected the polio virus in waterways, in the first cases of its kind since 1984.

According to the British “Sky News” network, monitoring these cases is a big event, even if the risk to children and young people is within a low level.

Children in Britain receive a regular vaccination against the polio virus, and this reduces the possibility of transmission of the disease between individuals.

The source stated that even in the event of an outbreak of the disease among a minority of unvaccinated people, the health system will move quickly to keep things under control.

But the ability of polio to regain a foothold, albeit limited, within the confines of an advanced health system, warns that the virus is still able to return as long as medicine has not completely eradicated it.

The monitoring of these cases of polio in Britain raises questions about why it appears in the United Kingdom and not in other European countries.

And “Sky News” wrote that no other European country – with the exception of Britain – witnessed the detection of a case of polio caused by the dead virus in vaccines, since the country was declared free of the disease twenty years ago.

Some vaccines depend on injecting the body with dead or very weak copies of viruses so that the immune system can recognize them and be able to neutralize them, in the event of an actual infection.

During the past twenty years, only four cases of dead or attenuated virus in the vaccine have been recorded, two of them in Ukraine, a third in Tajikistan, and a fourth in Israel.

Health experts say that when the level of vaccination is poor somewhere, the weakened virus can live for a long time and may mutate and pass into a more deadly form.

The virus infects 1 in 200 children with incurable paralysis, while between 5 and 10 percent of them die if the disease extends to the respiratory system.
