WHO officials has released a statement in which they said that a strain of polio virus has been found in the sewage of the Sao Paulo’s international airport located in Brazil.
However they have also mentioned that there is no need of panic because no human cases were found. Because of the widespread immunization done against polio, the chances of anyone getting infected by polio virus are rare.
In a statement, WHO said ”Given the high levels of population immunity indicated by the high routine immunization coverage and implementation of periodic vaccination campaigns in the area — no evidence so far of (polio) transmission and the response being implemented — the World Health Organization (WHO) assesses the risk of further international spread of this virus from Brazil as very low”
But it’s definitely alarming. Polio, the virus which has been eradicated from most of the developed countries can return if any of the visitors to Brazil will get infected. Given the fact that there is an ongoing FIFA event, there is huge number of visitors in Brazil from all over the world.
Earlier this year, WHO declared a Polio Health Emergency. The emergency was declared after the virus strains were found in some countries where the polio disease was already eradicated.
In theory, it is said that if one person gets infected by Polio and remains undiagnosed, it can quickly spread to surrounding 100,000.
The virus strain found in Brazil came from a country of Africa, the Equatorial Guinea. Earlier this month, the same country has also reported 4 new cases of Polio virus.
