Of these, 5 individuals developed a critical complication referred to as hemolytic uremic syndrome, a uncommon situation that damages kidneys, stated Katherine McCombs, deputy director of surveillance and investigation on the Virginia Division of Well being Workplace of Epidemiology.
The Virginia case highlights the necessity for guests to lakes and leisure water spots to be cautious about bacterial illnesses and different potential risks lurking within the water.
“Water can have micro organism in it – and positively not only for E. coli, however for many different issues,” stated McCombs.
As we careen into summer time, USA TODAY is highlighting some key water-borne threats that will not be seen to the bare eye.
How typically do individuals get sick from lakes?
Swimming in lakes, rivers and oceans can expose individuals to a wide range of pathogens.
Since 2009, greater than 2,700 individuals have change into in poor health in additional than 100 outbreaks at such outside water spots that had not been handled with chlorine or didn’t have filtration techniques, in response to the Facilities for Illness Management and Prevention. Dozens of individuals had been hospitalized after falling in poor health from abdomen bugs or different sicknesses at these websites.
Persons are particularly weak to lake and water-based pathogens in the summertime months, doubtless as a result of hotter climate prompts individuals to hunt cool water. June, July and August are the most typical season for individuals to change into sickened at lakes and different outside water spots, in response to CDC knowledge.
A CDC research stated outbreaks from germs in leisure water typically stem from pathogens comparable to norovirus and E. coli. These pathogens can come from human feces, vomit, stormwater runoff, sewage or septic system malfunctions. Animal waste in leisure hotspots can carry pathogens if individuals swim or play in contaminated waters.
Watch out for brain-eating amoebas, too
One other uncommon however typically deadly threat entails the amoeba Naegleria fowleri, a brain-eating amoeba. Final August, a Travis County, Texas resident died after turning into contaminated throughout a swim at Lake Lyndon B. Johnson, outdoors of Austin.
Mind infections, referred to as amoebic meningitis, can happen in freshwater lakes with this amoeba when water is compelled up the nostril throughout an exercise comparable to diving or water snowboarding.

In response to the outbreak, New York handed public well being rules that mandated splash pads have ultraviolet gentle techniques to kill these microscopic germs, in response to the CDC.

Youngsters, pregnant girls and other people with weakened immune techniques are particularly weak to this frequent public swimming pool bug, in response to the Nationwide Institutes of Well being.
Virginia lake outbreak probe continues
McCombs, of the Virginia Division of Well being, stated the state was awaiting the outcomes of water take a look at samples drawn from Lake Anna on Tuesday. The assessments usually take about 48 hours to finish.
Well being officers additionally interviewed the 20 individuals contaminated with E. coli to make sure there wasn’t a standard trigger for the sickness, comparable to consuming the identical sort of contaminated meals or publicity to an contaminated particular person.
“We’re nonetheless on the level of gathering quite a lot of data to see if we will rule out any of these components,” McCombs stated.
She stated E. coli outbreaks are sometimes linked to consuming contaminated and undercooked meals, such because the outbreaks linked to romaine lettuce, however contaminated water will also be a supply of an infection.
“We’re used to it (E. coli) being extra of a foodborne factor, however it actually may be transmitted by water as properly,” McCombs stated.
Take these steps to remain secure when swimming, boating pure waters
Folks swimming or boating in lakes and different pure waters ought to keep away from swallowing water, McCombs stated.
