evidence: A viral image circulating online is falsely advising social media users that gargling water with salt or vinegar "eliminates" the coronavirus. There is currently "no specific medicine recommended to prevent or treat the new coronavirus," according to the World Health Organization. [...] One of the latest falsehoods concerning the coronavirus to spread widely on Facebook and Instagram tells users, wrongly, that simply gargling water with salt or vinegar "eliminates" the virus. The viral image spreading the claim erroneously purports that, "before it reaches the lungs," the coronavirus "remains in the throat for four days" and that drinking a lot of water "and gargling with warm water & salt or vinegar eliminates the virus."
