Rio ’s wateris ugly — full ofraw sewage and drained bodies — and later this calendar week , humanness ’s top athletes will plunge into this hellish sweat for a middling ol’ external sporting competition .
At this item , it ’s too late for Brazil to properly houseclean up Rio ’s befouled waterways for the 2016 Summer Olympic Games . Leaving spectator pump and athletes alike with one bowel - rick motion : how much of a literal shit - show is this Olympics conk to be ?
I posed a sanitized reading of that question to doctors and epidemiologists conversant with Rio ’s water . The general consensus was bleak . Many citizenry will be exposed to waterborne illnesses , and some will get violently ill . However , athletes whose sports take place in the water can reduce their personal risk with a few basic caution .
For the preceding year , media reports have painted a ghastly picture of the Department of State of Rio ’s waterways , which are blackened by the ceaseless flow of human waste matter from densely populated neighborhood that lack modern sewage treatment . Evan as Olympic officials insist they ’d “ never risk the health of athletes ” for a competitor , a16 - month - long investigationby the Associated Press has revealed otherwise : Rio ’s water is overrun with disease - causing organisms , pretty much all the time .
“ From a microbiological stop of view , this pee is comparable to peeled sewage , ” said Fernando Spilki , the virologist at Feevale University in southern Brazil who comport the AP ’s body of water test .
Among Spilki ’s more disturbing finding are that the water is load with rotavirus , which is associated with emesis , looseness , and all - around misery . The analysis also bring out disturbing spike in the levels of fecal coliform bacteria ; a marker for disease like Indian cholera , dysentery , hepatitis A and typhoid , to name but a few . An epidemiologist who preferred to speak off record noted that similar level of fecal coliform would cause US beaches to be shut down .
Then there ’s therecent oeuvre of Renata Picao , a microbiologist at Rio ’s federal university , who found grievous , multi drug - resistant bacteria at five Rio beach , including the one where swim competitions will take seat . As Picao told Gizmodo , she await these bugs to be rare and was surprised to retrieve them “ extremely well ” from coastal waters .
understandably , the good track of action mechanism is to deflect Rio ’s fetid ocean slop entirely , but that ’s not an option for many of this summertime ’s Olympian athletes . So , how many of them are going to get sick at the Olympics ? And can anything be done to come down personal risk ?
The first thing to know is that any contact with the water virtually guarantees contagion , accord to Kristina Mena , a waterborne pathogen expert who conducted a risk analytic thinking establish on Spilki ’s datum . “ stratum of these organism are so high , that every jock interact with the water will be expose , ” Mena told Gizmodo . “ Even with diminished amounts of [ water vulnerability ] the jeopardy of transmission is 99.999 percent . ”
But just because a person becomes infected does n’t mean they ’ll manifest critical symptoms . That reckon on a innkeeper of factor , including the mortal ’s overall health , past exposure history , and immediate photograph level .
Children , the elderly , and immunocompromised someone are go to be at greater risk than young to halfway - aged adults , especially when it comes to multi drug - resistant bugs . For healthy adults including Olympic athletes , innate resistance will calculate on past pic to Rio ’s disease - causing pathogens . It ’s potential that people who spring up up in place with poor sanitization will fare slimly well than athletes who ’ve enjoy white water their entire lives , but it ’s hard to make mantle statements because viruses mutate quick and are site - specific .
Moreover , when you ’re swimming in what amounts to an heart-to-heart sewer , the most robust resistant system ca n’t protect you from everything . “ reduce risk means denigrate exposure , ” Mena say .
That stand for trying your expert not to take back water , wearing tight goggles ( or justkeeping your head from going under ) , and shower frequently . It mean not rubbing your eyes , using hired hand sanitizer liberally , and make certain that any scrape are immediately clean and incubate . For some athletes , it even meansbleaching oar handles and boatsor wearing plastic wooing and baseball mitt .
Most of all , minimizing photograph means deflect contact with the water to the high degree potential .
Neil Fishman , a professor of infectious disease at Penn Medicine , added an additional note of precaution about prophylactic antibiotic drug . “ I think taking antibiotics [ preventatively ] can cause more harm than serious , ” he said , noting that whether or not an antibiotic will form reckon on the character of pathogen a person is uncover to ( and antibiotics wo n’t work against viruses at all ) . Meanwhile , antibiotics can wreak all sort of havoc on the body ’s native microbiome , leaving a person more susceptible to opportunistic infection like C. difficile .
“ I think the only choice is speedy treatment position - contagion , ” he said .
Picao added that if a cut make grow sign of infection , the affected role should immediately warn his or her physician of possible exposure to multi drug - resistant bacteria .
So , let ’s review . If you ’re headed to Rio this calendar month , either to compete or delight the apocalypse as a spectator , support in mind any contact with the pee almost warrant exposure to something that can cause looseness of the bowels or uncollectible . If you ca n’t avoid contact , circumscribe it , shower down frequently , and go to the doctor as soon as you ’re home . With a little luck , you ’ll issue from the experience of swimming in a toilet with nerves of steel , a soup - up immune organization , and a deep appreciation for the wonders of advanced sanitation .
