Social media is awash with bogus COVID treatments. Offset, at that place was hydroxychloroquine, then bleach, followed hard on the heels by ivermectin – a cattle dewormer. The latest on the scene is povidone-iodine, an antiseptic.

Some people have claimed on social media that gargling with iodine can prevent the spread and severity of a COVID infection, suggesting it every bit an alternative to getting the vaccine.

Iodine has been used as an antiseptic for almost ii centuries, with povidone-iodine being a commonly used modern grooming. Laboratory studies have shown that it is constructive against coronavirus, inactivating it in as little as 15 seconds. This caused the researchers who made the discovery to suggest that using povidone-iodine in the nose and rima oris could assist to reduce the person-to-person spread of coronavirus and limit the severity of the disease in those infected. This presumes that what happens in the test tube will likewise happen in humans, which is a significant bound of religion.

The idea of halting infection in the oral cavity has been around for a while. Until the 1970s, the makers of Listerine mouthwash claimed that using it regularly could foreclose colds and sore throats, until they were obliged to remove this claim considering of lack of evidence. Trials since then that have looked at gargling to reduce colds and flu accept shown alien results, with little evidence of any worthwhile benefit.

In Japan, daily gargling for hygienic reasons has been a mutual cultural do for centuries, using everything from water, to tea, to antiseptics. During a press conference in August 2020, the country governor of Osaka prefecture, responding to a very small enquiry written report, suggested that gargling with povidone-iodine would help preclude COVID. When questioned almost the forcefulness of the scientific evidence, he side-stepped the question, replying: "It's worth giving a try."

Like communication – based on a hunch – has been offered by oral-wellness experts in the Great britain.

A contempo review of the evidence attempted to answer the question: does povidone-iodine reduce the manual of COVID? Much of this research turned out to be laboratory studies, with relatively few trials carried out on patients.

While these patient-based studies suggest that povidone-iodine can inactivate coronavirus in the oral cavity for a period of time - an unsurprising finding - there is non a single study to date that shows information technology volition stop the transmission of coronavirus or reduce the severity of the illness in those already infected. Using a uncomplicated analogy, cleaning down a work surface with antiseptic wipes will only ever provide temporary disinfection.

Questionable argument

The "worth giving a endeavour" argument is questionable. From a practical indicate of view, povidone-iodine is difficult for many patients to use in the mouth and nose every bit it tastes and smells disgusting. While side-effects of povidone-iodine are mostly tolerable, irritation of the skin is common and sometimes severe. More rarely, simply more than seriously, povidone-iodine can cause an underactive thyroid gland, especially in pregnant women.

The makers of povidone-iodine are clear in advising people that their products are not designed for gargling or putting in the nose to forestall COVID.

Aside from the firsthand risks of using povidone-iodine inside the body, is the harmful effect of promoting treatments for a pandemic that are not based on reliable evidence, particularly when in that location are measurably constructive alternatives. Gargling with iodine won't stop you from getting COVID, but it may distract y'all from something that volition: vaccines.
