Professionals from the Catalan Public Health Agency have detected the presence of poliovirus, known as polio, in the sewage from two wastewater treatment plants in the Baix Llobregat region. The Department of Health has already alerted primary care centers (CAP) and hospitals in case a person with symptoms compatible with the disease comes to the clinic, and they have begun an investigation to try to locate them. Even so, the Secretary of Public Health, Esteve Fernández, emphasizes to ARA that the risk of spread is very low because vaccination coverage is up to 97%.
