More than 40 swingers have tested positive for coronavirus following a Naughty in N'awlins convention, it has been confirmed.

Organiser Bob Hannaford expressed in a blog post he'd had hesitations about going ahead with the event in New Orleans but sought advice and put "extraordinary measures" in place to make it safe.

However he said once the event was over, he began to receive text messages about positive Covid-19 results.

He wrote: "When we contacted the people that were positive, we asked them several questions to find more potential positive cases and try to find out where the biggest risks took place.

"In almost every case, they admitted to us that they were super diligent on the first two days (Wed & Thurs) and then they relaxed a little on Friday and then they said “F**k it, it’s our last day” and many admitted that their lax effort on that final day is probably why they ended up positive."

He added: "You see, we have no idea how many people got tested after our event, nor if anyone tested positive and didn’t tell us."

Mr Hannaford said they'd gone to extraordinary measures for check-in and put in place a touchless process with temperature checks, social distancing in line, and sanitizing upon check-in.

"We issued wristbands in one color to indicate who had antibodies and therefore was not contagious," he continued in his blog.

"We issued a second colour to those that showed us a very recent negative Covid-19 test. The wristbands even had each person’s date of their test circled."

He said more than 50% of attendees had antibodies and many others had been tested right before the event, which made him feel better about any potential risk.

He also said people were required to wear masks in all public places.

The blog post said however they ended up with 41 known positive cases out of the 300 attendees.

Mr Hannaford admitted if he could go back in time, he would not put the event on again.
