Can gargling with salt water or vinegar eliminate coronavirus?
The short answer is, no. A theory circulated early on that the coronavirus stays in the throat for a few days before making its way into the lungs. To counter that, some have suggested that gargling with salt water or vinegar could wash the virus out of your throat, preventing it from either taking hold or getting down into your lungs. Not only is there no evidence for this, but given the way the virus most commonly enters the body, gargling won’t help prevent infection. Typically, the virus enters your body when you breathe in virus that’s floating in the air after it was coughed or sneezed by an infected person. Another way the virus gains entry into our body is when we touch our nose with our hands contaminated with virus. In both instances, the virus never lands in the part of the throat that gargling would even touch.
