There is no cure for the coronavirus, but passengers stuck aboard a quarantined ship are being offered a cure for boredom – free webcam sessions with porn stars.

Adult site CamSoda is offering the nearly 3,700 people suffering from cabin fever on the Diamond Princess, which is docked in Japan, gratis access to its models.

“They are not only dealing with the fear of infection, which is terrifying, but boredom,” CamSoda VP Daryn Parker said in a news release.

“We like cruises just as much as the next guy, but without activities or human interaction, the boredom must be crippling,” he added.

“In an effort to keep their minds off of the coronavirus and to help with the boredom, we’re offering passengers and crews the ability to have fun in a safe and controlled environment with camming,” Parker said.

The offer also was extended to those cooped up aboard the World Dream — but all 35 people who had reported symptoms tested negative and everyone was allowed to disembark after a four-day quarantine in Hong Kong.

CamSoda said 1,000 free tokens can be redeemed by each crew member and passenger by sending a copy of their ticket or staff credentials to stranded@camsoda.com.

Tokens are the “currency of the cam world” and can be used for interacting via video and instant messaging during camming sessions, according to the company.

“Sessions can be sexual and sensual in nature, but don’t have to be,” CamSoda noted.

Those interested will have to set up a CamSoda account before gaining access to the site.

At least two dozen Americans are among the passengers infected with the coronavirus on the Diamond Princess, which has been under quarantine since Tuesday after a Hong Kong man who sailed on the vessel tested positive for the coronavirus.

The number of confirmed cases on the ship nearly doubled Monday, climbing from 70 to 135, according to CNN.

CamSoda recently offered football players on the San Francisco 49ers and the Kansas City Chiefs free webcams while they were away from home for Super Bowl LIV, according to the Miami New Times.

“The offer isn’t a gateway to porn … it’s a security measure to ward off potential thieves,” Parker said, explaining that the players could livestream the feed from their homes.

And earlier this year, the site offered Jacksonville Jaguars QB Gardner Minshew a $1 million endorsement deal to lead weekly fitness classes in the buff or in a jockstrap.
