evidence: A supposed corona virus prevention formula was circulating on the internet in previous months. According to the text, shared on the WhatsApp platform by Brazilian users, gargling with water, salt and vinegar is sufficient to eliminate the virus from the person’s throat, where it "stays for four days before going to her lung" (data given by the same text message). This mixture, supposedly, will prevent the virus from reaching the lungs and prevent critical medical problems caused by this infection. Soon the message and new variants, were spreading over social media all over the world. [...] "The Corona virus, before reaching the lungs, it remains in the throat for 4 days, this is the time where the person start to cough and have pain in the throat. If she drinks a lot of water and gargles with warm water, salt or vinegar, the virus is eliminated. Spread this information because you can save someone with this." [...] "Gargling can be good to help relieve cough, but saying that warm water, salt and vinegar eliminates the virus is a big nonsense," said Leonardo Weissmann, an infectious disease physician and consultant at the Brazilian Society of Infectious Diseases, in an interview for the news vehicle G1.
