London authorities have discovered poliovirus in wastewater. However, they do not take on any new health risks. Nevertheless, they assume that pathogens can spread. How dangerous would the outbreak be to people?

Poliovirus discovered: The risk of infection is currently so high
Signs of community poliovirus transmission were found for the first time during routine wastewater inspections in the north and east of the metropolis. As early as February 2022, experts were able to find positive samples at the Beckton Wastewater Treatment Plant in Newham, according to the UK Health and Safety Agency (UKHSA).

Polio: These are symptoms that you need to watch out for
For centuries, poliovirus has caused many people to develop poliomyelitis, also known as polio or palsy. The name polio refers to the fact that it mainly affects children under five years of age. After infection, the virus attacks the nervous system and causes paralysis or even death in severe cases. The polio virus is highly contagious. Even people who are not sick can infect their surroundings. Polio is transmitted by coughing, sneezing and objects contaminated with feces.
Symptoms of poliovirus infection are rather non-specific. They resemble flu. Sore throat, fever, headache or abdominal pain may indicate paralysis. The symptoms usually last for ten days and then disappear. In very rare cases, the patient suffers from foot problems. It also usually subsides within a few weeks or months. If you suffer from similar symptoms, have them checked by a doctor. They can also indicate other diseases.
Is there a therapy for polio?
There is no cure for polio, only a vaccine. This protects against infection. Anyone who has not been vaccinated as a child can do so.
