Nurse!

Elon Musk's coming to the rescue as Los Angeles gears up to fight the deadly coronavirus ... because he's already following through with a promise to supply ventilators to patients in need.

California Governor Gavin Newsom just said the Tesla founder has already delivered the 1,000 ventilators he promised to Los Angeles, this less than a week after Elon said he was ready to pitch in for relief efforts with some much-needed medical supplies.

As we reported ... Elon offered to have one of his Tesla factories start making ventilators to help battle the COVID-19 pandemic after catching some flak on social media.

When there's a hole in the market, someone's gonna fill it, so it's no surprise some private companies are already springing up offering at-home coronavirus test kits.

Carbon Health and Nurx have fired up in-home sample collection kits. It goes like this ... The companies deliver swab collection kits. Customers get a mucus sample and send it back for testing at a lab.

There is room for error, so both Carbon Health and Nurx are offering consults with doctors to make sure the results are evaluated correctly.

We spoke with someone who tried getting the test today from Nurx. She said customers were allowed to go on the site at 7 AM and within minutes they were sold out for the day.

The CEO of Carbon Health says they're hoping to sell as many at 10,000 kits a day in a matter of 2 weeks.

The cost -- Carbon Health will run you $167.50, and Nurx a tad higher at $181.

Here's how desperate it's getting ... medical professionals in England are so strapped for supplies, nurses are now wearing trash bags to protect themselves from the coronavirus.

The pic was snapped at Northwick Park Hospital in London. The hospital declared an emergency Thursday after it was filled to capacity in the critical care unit.

One of the nurses in the photo said, "We are so disheartened with what we face day by day, night by night."  Doctors and nurses are begging for proper gowns, masks and gloves.

Six people have died at the hospital and dozens are in ICU.

This is a sign of the times everywhere ... in the U.S. there's been talk of doctors and nurses using scarves if masks aren't available.

Los Angeles is implementing what seems to be inevitably coming for the rest of the U.S. sooner than later -- a 24-hour mandated quarantine for all residents to help "flatten the curve" of the coronavirus pandemic.

L.A. residents will no longer be able to leave their homes around-the-clock for the next month -- as ordered by Mayor Eric Garcetti -- except for medical reasons and grocery store runs. It's called the "Safer at Home" order.

The new countywide policy comes on the heels of the city of San Francisco enacting the same rules, which match what Italy began doing last week after it was hit hard by COVID-19 cases.

Garcetti says the lockdown will be in effect starting Friday and ending on April 19 ... at least that's the plan for now.

The "Safer at Home" order mandates the closure of all shopping centers, indoor malls, playgrounds and non-essential business, while also prohibiting gatherings of more than 10 people in enclosed spaces.

Residents can still leave their homes to go on walks to get exercise, and to get food and gas. People can also leave their homes to go care for loved ones.

As we reported ... along with the San Fran shutdown, 6 additional Bay Area counties told residents to "shelter in place," which means unless your work falls under the list of "essential businesses," you're ordered to stay home.

That list includes healthcare operations, grocery stores, shelters, media outlets, gas stations, banks and restaurants -- but only for takeout and delivery. And, now L.A. is doing the same.

The aisles are mostly empty inside Sin City wedding chapels ... couples hoping to tie the knot at famous spots are canceling wedding plans left and right in the wake of a deadly pandemic ... and even Elvis ain't immune.

Four of the most popular wedding venues in Las Vegas are no longer booming in the face of the fast-spreading coronavirus ... with lots of would-be brides and grooms telling them they're too scared to go through with their destination weddings.

Vegas Wedding tells us they've had couples saying they made their decision over fears of contracting coronavirus. One bride cited her weakened immune system, saying travel and crowds are not worth the risk. Another family also bailed over travel fears.

Graceland Wedding Chapel is dealing with similar fears -- COVID-19 and travel. They tell us they do lots of weddings for Europeans, and Trump's travel ban has chapel owners worried about future bookings. The silver lining -- European couples can get a 2-year credit to reschedule nuptials if they cancel.

Ditto Wedding Chapel ... the owner tells us things are deathly slow ... and the European travel ban is already forcing last-minute cancellations.

Viva Las Vegas Wedding is getting at least 3 cancellations a day, while some couples say they're still coming because they won't let the virus ruin their lives.

The chapels are dealing with the same issues -- and working overtime to keep things sanitized -- and even Elvis Presley impersonators are feeling the effects.

The famous Elvis at Viva Las Vegas Wedding is washing his outfits way more often ... and he's got hand sanitizer at his podium, because he's still shaking hands and hugging couples for photos. Ditto for the Elvises at Graceland Wedding Chapel, where one impersonator is also cycling through 20 jumpsuits to stay extra-clean.

The impersonators spend a lot of time in the bathroom, just like the real Elvis ... only the wannabees are there to wash hands.

Cavs star Kevin Love is stepping up to help the hundreds of arena staffers out of work during the NBA suspension ... donating a HUGE amount of money to support the hard workers in Cleveland.

Love shared his feelings about the league shutting down on Thursday ... saying his concern isn't about basketball, but the people who help make the game day experience possible.

"Everyone reacts differently to stressful situations," Love said in a statement. "And the fear and anxiety resulting from the recent outbreak of COVID-19 can be extremely overwhelming."

Of course, the Association decided to suspend the 2019-20 season Wednesday ... after Utah Jazz stars Rudy Gobert and Donovan Mitchell tested positive for coronavirus.

"Through the game of basketball, we've been able to address major issues and stand together as a progressive league that cares about the players, the fans, and the communities where we work."

Love -- who is outspoken about mental health awareness -- says his foundation will write up a check for $100k to "support staff that had a sudden life shift due to the cancellation of the NBA season."

Along with the contribution ... the Cavs released a statement saying the team is currently working on finding a way to financially help the employees during the time off.

Cycling star Fernando Gaviria is giving hope to those infected by the coronavirus ... he posted a video Thursday insisting he's "fine" despite his diagnosis last month.

The 25-year-old Colombian revealed he was one of several who had contracted COVID-19 during February's 2020 UAE Tour race in the United Arab Emirates.

Gaviria confirmed he has been in the hospital and quarantined while battling the virus ... but said in Spanish on Thursday he's all good.

"Hello everyone, there are many rumors circulating in regard to my state of health, but I'm fine," Gaviria said. "I've been here, undergoing regular tests, which have returned positive for the coronavirus, but I'm feeling fine."

Gaviria added, "Thank you to my team and to everyone at the hospital who looked after me to perfection. I'm here to avoid infecting other people, and to avoid this continuing to spread in the way it currently is."

"This is to assure everyone that everything is going well, and let's hope it's all resolved soon."

Gaviria is one of many professional athletes who have revealed a positive diagnosis this week ... with the most notable one, NBA star Rudy Gobert, getting the confirmation Wednesday.

Steve-O's well aware of all the cancellations due to the coronavirus pandemic, but instead of freaking out ... he's cashing in on an uncrowded market and booking shows.

The "Jackass" star was at Gladstones Restaurant near Malibu, and told us because the South by Southwest Festival in Austin, TX was called off ... a lot of venues suddenly had open dates to fill.

So, Steve-O says his agent asked if he wanted to perform at The Paramount Theatre -- the site of his very first comedy special, and he couldn't turn it down.

Steve-O tells us he's done his due diligence to make sure he wasn't making a poor decision. That meant a call to his good buddy, Dr. Drew.

We broke the story ... Dr. Drew still believes the panic over COVID-19 is overblown and people just need to take precautions and be reasonable.

Sounds like he told Steve-O the same, and gave him his stamp of approval to head deep into the heart of Texas next week.

Steve-O tells us he plans to do meet and greets with anyone who comes to his show, but he's using common sense -- elbow bumps and side hugs only.

"Riverdale" is shutting down because someone on the production has a very real concern about coronavirus exposure.

A rep for Warner Bros., which produces the CW show, tells TMZ ... it recently was made aware that a team member from the show recently came in contact with a person -- not on the production -- who tested positive for the coronavirus.

We're told that team member is receiving medical evaluation and out of an abundance of caution, production is currently being suspended. The rep adds, "We are working closely with the appropriate authorities and health agencies in Vancouver (where they shoot) to identify and contact all individuals who may have come into direct contact with our team member."

The news comes shortly after a slew of organizations took extraordinary caution to stem the rapidly-spreading disease. As we reported, the NCAA announced it will ban fans from the tournament.

Jeremy Lin is sick and tired of the racism and xenophobia directed at Asian people over the coronavirus pandemic ... and now he's taking action to combat the hate.

The ex-NBA star -- who currently plays for the Beijing Ducks in the Chinese Basketball Association -- just donated $150,000 "towards fighting this virus."

Lin also spelled out on social media why he's upset over "news headlines of racism, xenophobia, attacks on Asians and decaying trust towards people" ... adding, "All heartbreaking and the opposite of God's kingdom."

"But for every fear-inducing headline, I see hope. I see doctors and nurses fighting the front lines in China, Korea, Japan, Iran, Italy and more. I see people helping people in countries regardless of race or background. Talk less out of hate, more out of empathy."

Lin pointed out several inspiring examples of bravery and hope:

-- "Lets talk about the man who made 16,000 meals for frontline workers."

-- "Lets appreciate the doctor who postponed his wedding and then tragically lost his life fighting the virus. He's a hero."

-- "Lets be inspired and demand justice for Meera Solanki who defended her Asian friend against an aggressive man in Birmingham only to be knocked unconscious."

-- "Lets follow suit and take action like Inner Mongolia who sent 2500 tons of potatoes to Wuhan."

On top of his $150k donation, Lin's basketball foundation in China has also donated roughly $150k to get medical equipment to Wuhan, the Chinese city at the center of the crisis.

Lin ended with some good advice ... "Let's all do our part to quarantine, wash our hands vigorously, wear a protective mask to avoid germs spreading and do our part to share facts and preventative measures. Stay together, fight on!"

Dr. Phil says folks who constantly fear getting sick are probably more at risk to contract coronavirus than the average Joe ... but not because of the virus itself.

The good doc came on "TMZ Live" Wednesday to talk about what's now a global pandemic and its effect on hypochondria. First off, he dropped some knowledge ... it's now called illness anxiety disorder, and he says people suffering from it are in "their perfect storm."

Phil says the wall-to-wall media coverage of coronavirus not only affirms their worst fears, it actually exacerbates the problem. Watch the clip ... he explains why their immune systems could be compromised by the panic.

Howie Mandel -- who's not a hypochondriac, but famously a germophobe -- showed up for 'AGT' Tuesday looking like most folks with illness anxiety disorder probably feel right about now.

Even more bad news ... Dr. Phil says it's near impossible now to convince them things aren't as bad as they seem.

'AGT' is having a rough go today -- first Howie Mandel shows up to set in a full hazmat suit ... and then we learned Heidi Klum was too ill to work.

Heidi showed up to shoot "America's Got Talent" in Pasadena Tuesday with a smile, but looks can be deceiving. She felt physically ill.

Only 3 judges entered the stage -- Heidi was missing. The judges told the audience she had a case of suspected food poisoning, and Sofia Vergara joked she had sent Heidi food last night. We've learned it was NOT food poisoning -- she just felt like crap.

Unclear what's ailing her, but people get sick all the time and it has nothing to do with the coronavirus.

Interesting ... there was a full audience for the taping today. TMZ broke the story, "Jeopardy!" and "Wheel of Fortune" are now taping without an audience. Ditto for Wendy Williams and Dr. Phil's shows.

No word if Heidi's gonna dress like Howie the next time she arrives on set ...

Travis Scott, Rage Against the Machine and Frank Ocean will be legends of the fall -- Coachella and its headliners are moving to October due to the coronavirus crisis.

TMZ has confirmed agents for several acts booked for Coachella have been told the new dates are the consecutive weekends of Oct. 9 and Oct. 16. The festival's promoter, Goldenvoice, is in the process now of informing reps for all the acts. The official announcement will likely come once that's done.

The massive music festival was originally scheduled for the weekends of April 10 and April 17, but it's now going the way of several other festivals that are either postponing or pulling the plug altogether.

South by Southwest canceled last week, as did the Ultra Music Festival in Miami. Even live touring legend Pearl Jam just announced it would postpone its upcoming spring dates.

County music fans gotta change their travel plans too -- the Stagecoach festival is postponing from April 24 to October 23.

All of this comes on the heels of other major shifts due to coronavirus fears. TMZ broke the story ... Justin Bieber is moving several of his stadium tour dates to arenas to ensure they can fill the venues, even with reduced ticket sales amid the crisis.

Congressman Matt Gaetz apparently made the rounds before he self-quarantined ... because we got this pic of him chowing down Friday at a West Palm Beach taco joint.

Gaetz hit up Rocco's Tacos and according to eyewitnesses, he was having a great time ... problem is, he had been exposed to someone diagnosed with coronavirus. Gaetz had been at a Conservative Political Action Conference in Maryland late last month and came in contact with someone who has been diagnosed with the virus.

The Congressman flew on Air Force One with President Trump Monday. Sources close to Gaetz tell TMZ ... the Congressman found out he had been exposed just after boarding the Presidential plane. We're told he then separated himself from others during the flight. Trump has not yet been tested for the virus.

We're told Gaetz is asymptomatic and was tested for the virus and he'll get his results later today. So far he's showing no signs of the virus.

Gaetz took heat for apparently clowning people on the House floor late last week by wearing a contraption over his face. Days later he was self-quarantined.

"The Bachelor" desperately wants to continue taping its 'After the Final Rose' show in front of a live studio audience, but hardcore fans first gotta come clean about the coronavirus.

TMZ's learned all guests attending the show Monday night were handed a COVID-19 disclosure form which gets straight to the point saying, "we are asking all guests to confirm they have not traveled within the past three weeks to or through a location that has been deemed 'Level 3' by the U.S. Centers for Disease Control."

In case audience members aren't plugged in ... the form, obtained by TMZ, lists the hot zones -- including Italy, Iran and China.

Producers also want guests to acknowledge they have not exhibited any coronavirus symptoms or even been in close contact, within 6 feet, with someone else exhibiting symptoms.

Part 2 of 'The Final Rose' is airing Tuesday night as well, and the audience attending will be asked to sign the same form.

For those who can't confirm any of what's in the form, producers say they "are happy to work with you to re-book audience tickets for a later date." The virus is now an issue for TV audiences all over Hollywood.
