Mostly False: “Gargles with warm water, salt or vinegar eliminate corona virus”

A supposed coronavirus prevention formula was circulating in the internet in previous weeks. 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.
