Nurse!

The coronavirus scare has now made its way to two of the most popular shows on television -- "Jeopardy!" and "Wheel of Fortune."

Production sources at the two shows tell TMZ ... as of Tuesday, 'Wheel' and 'Jeopardy' will be shot without live audiences. As for how long this will last ... our sources say it all depends on the spread of the virus.

Our sources say there are 3 primary concerns ... one of which is exclusive to 'Jeopardy.' Alex Trebek, who is battling stage 4 pancreatic cancer, has a compromised immune system from chemotherapy and other treatments. We're told execs felt it was too risky to expose him to large audiences.

There are two other concerns ... most of the audience members for both 'Jeopardy' and 'Wheel' are older -- lots of folks in their 60s -- and they are the most vulnerable to contract the virus and not beat it.

The third factor is that a number of people who attend tapings are from out of town and such travel is risky, given the spread of the virus.

The 4 major American pro sports leagues currently in season -- NBA, MLB, MLS, and NHL -- have all decided to temporarily ban the media from locker-room and clubhouse access due to Coronavirus.

“After consultation with infectious disease and public health experts, and given the issues that can be associated with close contact in pre- and post-game settings, all team locker rooms and clubhouses will be open only to players and essential employees of teams and team facilities until further notice," the 4 pro leagues said in a rare joint statement.

"Media access will be maintained in designated locations outside of the locker room and clubhouse setting.  These temporary changes will be effective beginning with tomorrow’s games and practices."

The decision to keep the locker-rooms and clubhouses to "essential" employees comes days after the NBA sent out a memo claiming games could be fan-less due to the coronavirus scare.

The leagues say the ban will begin Tuesday's games and practices ... and all media access will go down in designated locations outside the locker-rooms.

The coronavirus is now turning legal -- a quarantined cruise in California has been sued for allegedly putting passengers at risk ... when they knew the virus was running rampant on the ship.

Ronald and Eva Weissberger -- two elderly passengers who are currently on the Grand Princess cruise ship that was quarantined and stranded out in the Bay Area waters for at least a week -- just filed suit against the parent company, Princess Cruise Lines.

In the docs, obtained by TMZ, the couple claims the PCL was grossly negligent in allowing them and thousands of other passengers onboard in late February ... when the ship's staff knew damn well at least 2 other passengers with coronavirus had just disembarked from a previous voyage -- and at least one of them died as a result.

They go on to allege that PCL had an awful screening process -- claiming that the new group of passengers were only asked to fill out a basic piece of paper stating if they were sick or not. There was no other testing, so claim the Weissbergers.

Adding insult to injury, the couple goes on to claim that at least 62 passengers onboard the current cruise were also on the prior infected voyage. BTW, the Grand Princess was finally allowed to dock Monday in Oakland.

They have a damning quote that reads, "Incredibly, not one of those sixty two passengers or crew members who were mixing and mingling with the infected prior passengers were ever  examined during the instant voyage until being tested for the virus on Thursday March 5, 2020, two weeks after the ship sailed."

Bottom line ... the Weissbergers say they would have NEVER stepped foot on the ship had they known all these potentially infected people were all around them. Now they're traumatized from the fear of developing coronavirus ... especially because they're older and already have underlying medical conditions. They claim PCL put profits over the safety of their passengers.

Two of the top strip clubs in the country are doing their part to protect the public from COVID-19 ... and it sure beats the hell outta schlepping to Costco.

Here's the deal ... the world-famous Little Darlings in Las Vegas just announced a massive giveaway: 50,000 bottles of free hand sanitizer, one for each paying customer while supplies last.

Across the country in Tampa, Deja Vu Showgirls is giving away free face masks to the first 10,000 paying customers.

As you know ... fears over the spread of coronavirus are leading to empty shelves in all kinds of stores from coast-to-coast ... with people panic-buying masks, hand wipes, hand sanitizer, soap, toilet paper and all sorts of necessities.

So, instead of waiting in seemingly endless lines at big box stores ... you can skip the headache and pick up these in-demand items while getting a lap dance.

Yes, it's a bold display of capitalism at work -- but a pretty ingenious one. They get butts in seats, and you get precious commodities. We mean face masks and sanitizer, to be clear.

Win-win!!!

The first major sporting event in the United States has been canceled amid concerns of the coronavirus after a local tested positive for the disease and officials declared a public health emergency.

The BNP Paribas Open was supposed to start in Indian Wells, CA Monday and run until March 22. However, officials made the difficult decision to cancel Sunday night, saying, "It is not in the public interest of fans, players and neighboring areas for this tournament to proceed. We all have to join together to protect the community from the coronavirus outbreak."

The tournament -- attended by thousands of fans -- has featured some of the biggest names in tennis in the past like Serena Williams and Rafael Nadal.

The cancelation comes just hours after health officials revealed Riverside County -- where the tournament is played -- had it's first reported case of coronavirus.

What's more ... Indian Wells is just a few miles from Indio, California where Coachella is held. The music festival is attended by around 100,000 people each year and spans two weekends. Organizers have not yet canceled the event.

The run on toilet paper and wet wipes has nothing on seriously hard alcohol -- 'cause people fearing a full coronavirus outbreak are snatching up booze to cook up their own sanitizer.

Everclear, the potent 190-proof grain alcohol college kiddos traditionally use for Jell-O shots, is in crazy demand now that enterprising DIYers know it's one of few alcohols potent enough to kill nasty bugs like COVID-19.

The craze for the specialty booze is coast-to-coast. The good folks at Seattle's Downtown Spirits tell us they're fresh outta Everclear. A clerk says customers aren't hiding their intentions -- "They're buying it for the sanitizer." The price tag's a mere $20, but he told us it wasn't a commodity until this week.

We're told they sold 40 bottles in 2 days -- more than twice what they normally sell.

Ditto for Broadway Spirits in Manhattan's posh TriBeCa 'hood where they've had customers calling in to make sure Everclear's still in stock. A clerk there told us it's about to go on backorder.

As you know, brand-name germ killers like gels and wet wipes are vanishing from stores -- and the homemade craze started when the World Health Organization released a few recipes to help out newbie chefs.

They suggest folks pull isopropyl alcohol, hydrogen peroxide and glycerin (if you have it) from cupboards and start whisking to attempt a homemade Purell, if you will. Everclear would come in handy if you're short on isopropyl A.

The Center for Disease Control prefers washing hands. But if soap and water aren’t “readily available” the agency suggests using a hand sanitizer containing “60% alcohol.” Grain alcohol to the rescue!!!

Buyers should carefully read the label because some spirits don’t pack enough punch. Tito’s Handmade Vodka admitted on social media it "does not meet the current recommendation of the CDC."

Justin Bieber's tour is the latest live act to feel the effects of the coronavirus ... he's downgrading the venue size in several "secondary markets" and it's all because of the virus.

Bieber's got a massive stadium tour planned for the summer to promote his hugely successful 'Changes' album. Friday they announced stadium stops in Cleveland, Detroit, Arlington, Columbus and Nashville were canceled and moved to local arenas ... essentially cutting seat capacity in half.

Turns out just 3 days after Justin announced his tour ... coronavirus fears really blossomed. We're told prior to the news, ticket sales were hugely successful but then slowed in smaller markets.

Sources close to Justin say his team made the decision to relocate several tour stops to guarantee they could fill seats instead of performing to a half-empty stadium. We're told it's possible he could do multiple shows at one arena.

Justin isn't the only artist to feel the effects of coronavirus, Miami's Ultra Music Festival and SXSW in Austin, Texas were both canceled earlier this week.

Daymond John isn't one of the smartest business people around for nothin' ... 'cause he's already figured out how we can make the best of a bad situation and actually benefit.

Seriously ... at first it seems like heresy, talking about the upside of the virus, but he really makes compelling points. Think about how our economy can benefit from more domestic manufacturing, how people will save time commuting if they end up working from home, how people might eat healthier at home than if they were going out to restaurants every night.

Well, Daymond's not scared yet about going to restaurants, because we got him at the famed Dan Tana's Steakhouse on the Sunset Strip.

When life gives you fears over coronavirus ... make some hand sanitizer and sell it at your lemonade stand!!!

Check out these funny pics of two young entrepreneurs in Texas ... the kids are putting a twist on the classic suburban lemonade stand by hawking bottles of hand sanitizer for $3 a pop.

These smart salespeople are cashing in on the hand sanitizer craze ... as you know, people are stocking up on the stuff over fears of catching coronavirus, and stores across the country are selling out ... and they're taking extra precautions by including their Venmo. Money is dirty!

This lemonade hand sanitizer stand is right outside Austin ... makes sense, the city just declared a local disaster and the upcoming SXSW music festival is canceled.

Gotta hand it to these kids, they're making the most of a bad situation ... looks like the country is in great hands!!!

Coronavirus could explode in the nation's jails as inmates are squeezed in like sardines in filth.

TMZ has contacted various jails, including L.A. County Men's Jail as well as jails in San Francisco and New York. They all say they are wiping down surfaces at least daily and ramping up sanitation efforts.

Tell that to Jose Abalos, who just got out of L.A. County Men's Jail for "regular carjacking." He says he was placed in a cell that had not been cleaned from the previous inmate and it was disgusting ... it smelled like urine. He left Friday morning with a cough and wheezing. He says the jail gave him meds but he's worried and is going to a doctor.

Abalos also said no one from the jail told the inmates anything about coronavirus or how to prevent it.

Another inmate, Arturo, also was released from L.A. County Men's Jail Friday morning, and he says there was blood and fecal matter on the walls and says the place was dirty and disgusting. He says he had one shower in 20 days.

Dr. Oz is moving on from his crusade against breakfast to urge people to quit another customary activity in everyday life -- shaking hands.

The TV doc tells TMZ ... coronavirus fears are warranted because it's proving to be 5 times more contagious than the seasonal flu, but there are immediate steps everyone can take to help limit its spread. First and foremost ... cancel handshakes.

Dr. Oz points out that COVID-19 has elements which make it very difficult to control -- something he alluded to in January -- but by replacing a handshake with a fist bump, there's 10 times less bacteria transferred ... so that's a good start.

He even offers a fun way to do the friendly exchange, compliments of Rev. Run. You gotta check it out.
