Gargling Water With Salt Won’t ‘Eliminate’ Coronavirus


Quick Take

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.

It’s worth reiterating again: Beware of posts on social media claiming to offer tips or cures for the novel coronavirus.

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.”

The World Health Organization, however, notes that “to date, there is no specific medicine recommended to prevent or treat the new coronavirus,” which causes the COVID-19 disease.

While saline water or water with vinegar is sometimes used to help soothe a sore throat, “it doesn’t kill the virus,” Charles Dela Cruz, an associate professor of medicine in pulmonary and critical care at Yale University, told us.

“You’re not rinsing it away so it doesn’t go to your lungs,” Dela Cruz, also director of the university’s Center for Pulmonary Infection Research and Treatment, said in a phone interview.

The U.S. Centers for Disease Control and Prevention reports that symptoms — often fever, cough or shortness of breath — appear within 14 days of exposure.

As for actual advice, Dela Cruz said “the key is to limit getting infected.” He emphasized health officials’ guidance that people should frequently wash their hands with soap and water; avoid touching their faces; and avoid large crowds and close contact with people who are sick.
