RUMOURS that Hillary Clinton is dead have swept the Internet after the presidential candidate collapsed while at a 9/11 memorial over the weekend.

In the latest conspiracy theory around the presidential candidate's health, some US media have made the dubious reports that the 68-year-old in fact died while undergoing hospital treatment.

The questionable article, run by the US' ABC, hit the Internet with the headline "Hillary Clinton reported to have died under hospital treatment at Montefiore Medical Hospital."

The following headline claimed "Democrats in disagreement over procedures of renomination".

Theories that Clinton died after her dizzy spell at the memorial service were then shared across social media with many baffled by the rumours.

But others were not so taken in, pouring doubt over the theory and even claiming that hackers had been involved in the reports.

One Twitter user, Fixer guy, wrote: "So this popped up a little bit ago Um... Did I just fall down Alices' rabbit hole, or what? It vanished aft ~3 min"

He later said that he received an Err 404 when the article loaded.

Another wrote: "I saw a clip of them reporting it. Super short though, don't know what to make of it."

A third said: "IS SHE, REALLY? MAYBE NOT, No independent verification yet."

There have since been claims that the article was a hoax.

Many claim the Presidential hopeful and her team called on political impersonator Teresa Barnwell to stand in after Hillary was struck down with "walking pneumonia".

The 68-year-old sparked big fears for her health after being filmed stumbling into her motorcade after attending the 9/11 memorial service in New York.

She was then taken to her daughter Chelsea’s apartment to rest and emerged two hours later smiling, posing for photographs and telling everyone: "I’m feeling great. It’s a beautiful day in New York."

It is this 'miracle' recovery which quickly set the conspiracists' tongues wagging.

They say the person who exited the apartment building with a sprightly step was not Hillary.

Theorists point out her legs were too skinny, her nose was shaped slightly differently and her earlobes were a different size than they normally are. Other claim her fingers seem to have grown.

The rumour quickly took off on Twitter with more "facts" to prove the double was used.

Many pointed out the lack of secret service officers near the Presidential candidate.

Images circulating under the #HillarysBodyDouble hashtag contrasted enhanced photographs of her earlier in the day.

Later in the day impersonator Teresa Barnwell tweeted to say she wasn't even in New York that day.

Clinton’s doctor Lisa R. Bardack said in a statement that following the candidate’s Friday diagnosis, “she was put on antibiotics, and advised to rest and modify her schedule".

Her symptoms on Sunday were a result of overheating and dehydration, Bardack said, adding: “She is now re-hydrated and recovering nicely.”
