The United Nations warned Tuesday that the world has less than 60 days to stem the deadly Ebola epidemic — as ghoulish marketers began cashing in on the crisis with creepy, Ebola-inspired Halloween costumes.

Anthony Banbury, head of the UN’s Mission for Ebola Emergency Response, told the Security Council that he is “deeply, deeply worried” that current efforts to fight the disease aren’t enough.

“Ebola got a head start on us,” Banbury said.

“It is far ahead of us, it is running faster than us, and it is winning the race.”

Appearing via video link from Ghana, Banbury said disaster looms unless at least 70 percent of all people infected with Ebola are getting treated by Dec. 1.

In addition, 70 percent of all burials need to occur without contamination by that date, he said. “We need to do that within 60 days from Oct. 1. If we reach these targets, we can turn this epidemic around,” he said.

“If we fail at any of these, we fail entirely. With each passing day as more people are infected, the number of people infected grows exponentially.

“We either stop Ebola now or we face an entirely unprecedented situation for which we do not have a plan.”

Earlier Tuesday, the World Health Organization said the current Ebola outbreak in West Africa was far deadlier than previously thought.

WHO assistant director-general Dr. Bruce Aylward said the disease — which has killed more than 4,000 people — now has a mortality rate of 70 percent, up from an initial ­estimate of about 50 percent.

Aylward also warned that Ebola would start spreading to about 10,000 people a week by early December ­unless the disease is stopped.

There have only been about 1,000 new cases a week for the past three or four weeks, he said.

“The virus is still moving geographically and still escalating in capitals, and that’s what concerns me,” Aylward told reporters in ­Geneva.

Meanwhile, the deadly outbreak occurred just in time for opportunistic companies to start selling what they promise to be the most “viral” Halloween costume of the year — Ebola containment suits.

Revelers can pretend they’re warding off the deadly virus in a replica white hazmat suit, face shield, breathing mask, safety eye goggles and blue latex gloves, which sell for $79.99 online.

“The deadly Ebola virus has landed in the United States and the crisis has reached new levels of domestic escalation. You are sure to be prepared if any outbreak happens at your Halloween party,” reads the costume description on BrandsOnSale.com.

It has since become one of the most popular costumes on the site.

“We don’t stray away from anything that’s current or controversial or anything like that,” CEO Johnathon Weeks said.

But not everyone is dying of laughter over the controversial costume.

Physician’s assistant Maria McKenna, who works at a Philadelphia hospital, said the getup “definitely rubs me the wrong way.”

“Normally I think that irony and humor is funny, but this thing with the costumes, is it really that funny? I mean, Ebola’s not even under control yet,” McKenna griped.

Tony Bianchi, whose shop Halloween Adventure in the East Village doesn’t sell the Ebola costume, said hazmat costumes have been wildly popular in recent years thanks to the TV shows “Breaking Bad” and “The Walking Dead.”

“It’s becoming a standard,” he said. “Think about it like this: As soon as you put that on, you think of zombies . . . or you think of some viral infection.”

“Everybody’s sensitive to something. If I was a zombie, maybe I’d be upset.”
