The US Centres for Disease Control and Prevention (CDC) has managed to elicit a few chuckles online after warning swimmers about one particular issue.
"Don’t swim or let your kids swim if sick with diarrhoea," a tweet recently posted by the CDC says. "One person with diarrhoea can contaminate the entire pool."
The tweet contains a GIF image featuring a kid sliding down a waterslide while leaving a brown trail behind her, with a warning saying: "Don’t leave your mark at the pool this summer."
This announcement left many social media users rather amused, with one person joking about the CDC’s "literal sh*tposting."
Another joked about "sharting"...
And there were also those who asked what other activities should be avoided by people suffering from diarrhoea.
