Two Instagram pranksters have outraged New Yorkers by pretending to contaminate a subway carriage with coronavirus.

David Flores and Morris Cordewell donned hazmats suits for the stunt while holding a container filled with liquid that had biological hazard markings on it.

In the video Cordewell gets up and spills the liquid over the floor as train passengers quickly jump out of harm's way. However, it turns out their bucket contained Kool-Aid juice.

The latest prank comes as the coronavirus death toll soared to over 1,100, with more than 45,000 infected around the world. That includes 12 with the virus in the US.

'The first half people were kinda scared.' Cordewell told Business Insider. 'After we were like "Yo it's a prank," people were laughing.'

'There was one lady with her kids sitting next to me just laughing the whole time. I don't know how she knew it was a joke, but she knew it was a joke the whole time.' He added.

The New York City MTA, which operates the subway, said it had not been made aware of the video.

Although many agreed with the creators that their video was funny, others were not amused.

'What the f*** is wrong with people,' David Mack, an editor at Buzzfeed tweeted.

Although some of the train passengers appeared to laugh off the prank, others jumped out of the way

While a woman called Kelly Sue commented on Instagram: 'How can this be funny? People have died from the coronavirus.

'Very immature & stupid. Plus people are that gullible to think it would be transported like that, it's a virus & not in liquid form.'

Tyler Wallace, 19, of Joliet, Illinois, turned himself in to police on Thursday

But Flores told Business Insider he wasn't rattled by the critics: 'To be honest, to me, I feel them, but I know it was a joke. At the end of the day it was a joke.'

They are not the first to face a backlash after coronavirus pranks.

Last week Tyler Wallace, 19, from Joliet, Illinois, turned himself in after video emerged of him spraying 'coronavirus' over $7,000 worth of produce at a Walmart.

He is charged with misdemeanor counts of disorderly conduct, retail theft and criminal trespass to property.

Police allege that Wallace put a surgical mask over his mouth and put a homemade sign on his back that read 'Caution I have the coronavirus,' then walked through the store spraying Lysol on clothing, produce and other items.

Police do not believe that either teen has the new virus. 'It appears to have been a prank that went too far,' Joliet Police Sgt. Chris Botzum said.

Just days earlier an Instagram star, James Potok, incited chaos on a flight from Toronto to Jamaica when he allegedly yelled he had coronavirus.

Potok Philippe, real name James Potok, was arrested and charged with mischief on Monday after crew on board the WestJet plane from Toronto to Jamaica were alerted to his actions and the aircraft was forced to turn back.

A second flight was also cancelled as a result of the incident.

The 28-year-old from Vaughan, Ontario, told City News: 'It was simply a joke.'

The other 243 passengers didn't think it was funny when Potok stood up in the cabin and said: 'Can I get everybody’s attention please. I just came back from Hunan province, the capital of the coronavirus. I’m not feeling too well. Thank you.'

Airline crew asked him to put on a mask and gloves and the plane had to turn around.
