How Spain Keeps Polio Away, Eradicated in 2002 and Now Found in London’s Wastewater

  • WHO declared Europe a polio-free zone in 2002, and Spain has rarely reported a case since then

  • The latest health report detects only one case, which was imported from Senegal in 2021

  • Polio vaccination coverage in Spain exceeds 95%

Polio is believed to be eradicated since 2002. Spain has reported less than one case per million children over the past decade. And yet in the United Kingdom they are going to vaccinate a million minors against the disease, as an increase in its presence in wastewater has been detected. Polio virus is excreted through faeces, and therefore analysis of wastewater is a measure of the presence of the disease in a society, beyond the detection and reporting of official cases. In Spain, acute flaccid paralysis (AFP), the most severe form of poliovirus infection, is treated with surveillance. But it should be borne in mind that most of these infections go undetected: according to the Spanish Association of Pediatrics (AEP) 95% of poliovirus (polio) infections are asymptomatic, and causes less than 1% of paralysisNotifies the Ministry of Health.

The World Health Organization recommends polio surveillance by Spain because the disease was believed to be eradicated. Nevertheless, almost all First World children continue to be vaccinated. In Spain it is immunized with four doses throughout the life of a minor. In Spain, poliomyelitis is a disease worthy of immediate attention, clinical suspicion sufficient to notify it.

In Spain, poliomyelitis has been a notable disease since 1904. In 1964, vaccination with the oral polio vaccine began in campaigns, and in 1975 the vaccine was included in the first official childhood immunization program. High coverage was achieved early, so that The last endemic case of poliomyelitis was reported in 1988.,

Ten years later, in 1998, Spain joined the goal of eradicating polio in the world, and four years later, in 2002, the World Health Organization declared Europe a polio-free zone. In 2004, the oral polio vaccine was replaced by the inactivated vaccine. Vaccination coverage exceeds 95% since 1999,

The last epidemiological report on poliomyelitis from 2021 states that there were 31 suspected cases of this type of virus, but all were ruled out. Yes actually, Type 2 poliovirus was identified in a five-year-old Senegalese girl, As for health, it “shows that while the polio virus is prevalent in the world, surveillance and alert systems must be kept active to detect and prevent any potential transmission in a timely manner.” fortunately There were no secondary infections.

What is polio?

The AEP states that “poliovirus, with its three serotypes, It is highly contagious and spreads easily from person to person through the faecal, oral and respiratory routes. and has been responsible for many cases of paralysis and death around the world.”

Poliomyelitis or infantile paralysis is an acute viral disease that Causes permanent paralysis due to damage to nerve cells spinal motor.

There is no causal treatment for polio, it should therefore be restricted to symptomatic and support measures appropriate for its evolutionary stages. Basically, supportive treatment is done with rehabilitation and physiotherapy and with respiratory support (tracheostomy and mechanical ventilation) in cases of bulbar paralysis. Symptomatic treatment of constipation and pain (analgesics).
