The polio virus has been found in sewage samples near Sao Paulo in Brazil, one of the host cities for the current World Cup football tournament, the World Health Organization said.
No human case of the disease has been reported in Brazil so far.

Several national football teams have arrived to Sao Paulo via the Viracopos airport.
The United Nations agency said that it assessed the risk of further international spread of polio virus from Brazil as "very low."
Brazil has been polio-free since 1989.

Police in Brazil's biggest city say a construction worker has been killed in an accident on a monorail meant to expand Sao Paulo's transport network.
The worker was hit by a large concrete support beam that fell while being erected.
An investigation into the cause of the accident is underway.
Workers on Sao Paulo's subway system have announced they will launch an open-ended strike, the latest to hit Brazil in the run-up to the World Cup, News agency AFP have reported.
The strike raises fears of transport chaos in the Brazilian economic capital, a sprawling city of 20 million people, one week before it hosts the opening match on 12th June.
Dramatic footage has emerged of the moment a crane collapsed at a World Cup stadium in Sao Paulo, Brazil killing two workers.
The incident happened at the Corinthians Arena on Wednesday.
A construction worker at the Brazilian football stadium where two people died in an accident has told ITV News builders did not "cross safety limits", amid claims staff were told to keep working despite safety fears.
Brazil Correspondent Nick Ravenscroft reports.
A fatal construction accident at Sao Paulo's World Cup stadium may delay its opening until February, but FIFA is not worried about it being ready for the World Cup, Reuters has reported.
A preliminary investigation into yesterday's accident indicated that damage was confined to the concourse area and did not affect the stands that could have taken longer to fix, a Reuters source said.
FIFA has said all World Cup stadiums must be finished by the end of December, but that would appear impossible in Sao Paolo following the accident.
FIFA said earlier today it would not know the length of the delay at the venue "until next week at the earliest".
