No evidence behind DIY coronavirus ‘test’ shared hundreds of thousands of times on social media
Holding your breath for ten seconds ‘without coughing’ is not a legitimate test for Covid-19. This advice shared countless times on Facebook, Twitter and Whatsapp—either in block text or as an image—has no basis in fact.
Even if it’s been shared by someone you know, that doesn’t make it true. And in this health emergency, advice like this could lead to somebody infected with the virus to believe they are healthy and go on to infect others.
The same chain message claims that drinking water will ‘wash’ the virus into the stomach, where acid will kill it. This is also incorrect. Drinking water does not prevent an infection and there have been cases where the virus has survived in the stomach and affected people’s intestines. It’s important to call out bad information when you see it.
