A roundup of some of the most popular but completely untrue stories and visuals of the week. None of these are legit, even though they were shared widely on social media. The Associated Press checked them out. Here are the facts:

CLAIM

Breathing the steam from a mixture of boiling water, salt and orange peel will prevent or cure the new coronavirus.

THE FACTS

Steam may help soothe symptoms of the virus, but it will not prevent or cure it. In photo and video posts circulating widely on Facebook and Twitter, people can be seen standing over a pot of boiling water filled with the mixture as they breathe in the steam. In some cases, other items have been added, from chopped onion to aromatic oils. Variations of the videos received thousands of views on social media. "Steam Sea Salt and Orange peelings. Inhale the steam for 15 minutes. It Suppose to Prevent Corona Virus from entering the body. Seen it on social media and yes I'm doing it," said one Facebook post featuring a picture of the mixture. Inhaling steam can provide relief from the symptoms of the virus, such as soothing the mucus membranes of the nose or the back of the throat, experts say, but it will not kill the virus. 

CLAIM

If a child gets the new coronavirus and needs to be hospitalized, they will be separated from their parents and the parents will not have the chance to see them again.

THE FACTS

Hospitals are limiting visitors, but hospital officials say they are allowing one parent to remain with a child. 

CLAIM

Helicopters are being used to spray disinfectant over neighborhoods to prevent the spread of the new coronavirus.

THE FACTS

Officials have called the claim not only false, but dangerous to spread. 

CLAIM

A coronavirus vaccine, which is able to cure patients within three hours of injection, is ready for use. Trump will announce that the Roche medical company will launch the vaccine next Sunday with a million doses ready from it.

THE FACTS

A photo circulating on social media with the false claim shows a coronavirus testing kit made by a South Korean manufacturer, not a vaccine. A vaccine to prevent the coronavirus is in the works, but experts say nothing is expected for use for more than a year.
