evidence: FULL CLAIM: Corona virus before it reaches the lungs it remains in the throat for four days and at this time the person begins to cough and have throat pains. If he drinks water a lot and gargling with warm water & salt or vinegar eliminates the virus. The claim that SARS-CoV-2, the virus that causes COVID-19, can be stopped in its tracks by gargling warm water, salt water, or vinegar went viral on Facebook in March 2020, notably through a widely shared meme, receiving hundreds of thousands to millions of interactions in total. This claim is factually inaccurate and unsupported by scientific evidence. [...] In summary, there is no evidence to suggest that gargling warm water, salt water, or vinegar is effective against SARS-CoV-2 in infected tissues, although gargling salt water might ease symptoms of a sore throat. Furthermore, by the time symptoms appear, localized treatments would be completely ineffective because the virus will have already spread to non-targeted tissues. There is currently no vaccine or cure for COVID-19. The best methods of prevention are frequent handwashing, disinfecting surfaces, and avoiding touching your face.
