Skip to comments.Polio virus found in Sao Paulo sewage, no human case: WHO
Posted on 06/23/2014 2:40:00 PM PDT by Oldeconomybuyer
The polio virus has been found in sewage samples near Sao Paulo, one of the venues for the soccer World Cup in Brazil, but no human case of the disease has been reported so far, the World Health Organization said on Monday.
The virus discovered in Sao Paulo sewage collected in March at Viracopos International Airport, and reported by Brazilian health authorities last week, is a close match to a strain isolated in a case in Equatorial Guinea, the WHO said.
"(The) virus has been detected in the sewage only ... To date no case of paralytic polio has been reported," it said in a statement.

The orchestra is warming up. The tune will be contagious, the song will be deadly.
So close to eliminating it and then fools undid all that work.
I’d love to hear from one of our medical community on this one. Seems to me that shedding polio virus in feces is something that happens after immunization with the attenuated virus oral vaccine. Not sure what strain of virus one would recover though . . .
Or, someone passing through the airport had it....
Having been to Sao Paulo, I would be shocked if the Polio virus were not in the sewer.
Food from street and beach vendors has a bad hygienic reputation in Brazil. The later in the day, the worse it gets. Bottled and canned drinks are safe, although some people will insist on using a straw to avoid contact with the exterior of the container.
Bear in mind the heat and humidity when storing perishable foods.
Tap water varies from place to place, (from contaminated, saline or soaked with chlorine to plain drinkable) and Brazilians themselves usually prefer to have it filtered.
In airports, bus stations, as well as many of the cheaper hotels, it is common to find drinking fountains (bebedouro), although not always safe. In hostel kitchens, look for the tap with the cylindrical filter attached. In more expensive hotels, there is often no publicly accessible fountain, and bedrooms contain minibars selling you mineral water at extremely inflated prices.
Vaccination against yellow fever and taking anti-malaria medication may be necessary if you are traveling to central-western (Mato Grosso) or northern (Amazon) regions. If you’re arriving from Peru, Colombia or Bolivia, proof of yellow fever vaccination is required before you enter Brazil. Some countries, such as Australia and South Africa, will require evidence of yellow fever vaccination before allowing you enter the country if you have been in any part of Brazil within the previous week. Check the requirements of any country you will travel to from Brazil.
Public hospitals tend to be crowded and terrible. Most cities of at least 60,000 inhabitants have good private health care.
Dentists abound and are way cheaper than North America and Western Europe. In general, the quality of their work is consistent, but ask a local for advice and a recommendation.
I would just like to know what possessed them to test sewage for any type of virus. Is that common practice? Is this something they do in a $#!*hole country before a large event, or do we do it here too?
Makes you wonder, that’s for sure.
On 18 June 2014, the National IHR Focal Point for Brazil reported the isolation of wild poliovirus type 1 (WPV1) from sewage samples collected in March 2014 at Viracopos International Airport, in Campinas municipality in the State of São Paulo, Brazil. Virus has been detected in the sewage only; sewage samples collected from the same site subsequent to the detection of WPV1 have been either negative or only positive for Sabin strains or non-polio enteroviruses; to date no case of paralytic polio has been reported. The isolate was detected through routine environmental surveillance testing of sewage water; there is no evidence of transmission of WPV1.
The Sabin strain referred to in this excerpt is the vaccine strain. The risk of paralytic disease from the vaccine strain is several orders of magnitude less than from any of the wild strains.
Testing sewage for presence of polio virus is a common method of surveillance. Its presence is an indicator that public health officials need to investigate to find out where the virus came from, and to isolate cases and vaccinate as necessary to stamp it out.
Good info thank you.
Thanks for the ping!
You’re Welcome, Alamo-Girl!
Post to me or FReep mail to be on/off the Bring Out Your Dead ping list.
The purpose of the Bring Out Your Dead ping list (formerly the Ebola ping list) is very early warning of emerging pandemics, as such it has a high false positive rate.
So far the false positive rate is 100%.
At some point we may well have a high mortality pandemic, and likely as not the Bring Out Your Dead threads will miss the beginning entirely.
*sigh* Such is life, and death...
Polio is generally a disease of the intestines and, while unpleasant, has no lasting effect on most people.
So, yes, someone with polio was pooping there.
