When a possible measles case is identified in California, a phone rings at the local health department and the clock starts ticking.

Laboratory workers need to process samples as soon as possible to confirm the case. And a public health nurse must call the patient to find out where they’ve been and who they’ve been in contact with recently.

If test results are positive, the communicable disease team has 72 hours or less to identify anyone who has been exposed and may be at high risk of infection or serious illness. Those people must quarantine or take a dose of a post-exposure prophylaxis to prevent spread. For the next 21 days nurses will monitor the group for symptoms.

Measles is the most contagious vaccine-preventable viral infection in the world, and California is fighting multiple outbreaks. In a room where one person is infected, nine out of 10 unvaccinated people will also contract the disease. The viral particles also linger in the air long after the contagious person leaves, risking exposure to those who enter the room up to two hours later.

“That’s ridiculously infectious,” said Dr. Sharon Balter, director of acute communicable disease control with Los Angeles County public health. “It balloons very quickly, and because measles spreads very fast we have to get on it right away. We can’t say we’ll wait until tomorrow.”

California has a high enough vaccination rate — about 95% of kindergarteners — to provide herd immunity against measles, but throughout the state pockets of unvaccinated communities drive outbreaks, experts say.

Shasta and Riverside counties are working to contain localized outbreaks. These are the first measles outbreaks in the state since 2020 and are happening at a time when health departments have less money and fewer staff than in recent years. In total, seven counties have reported a total of 21 measles cases this year, according to the California Department of Public Health.

Throughout the country, 26 states have reported measles cases since the start of the year, including a massive outbreak in South Carolina where officials identified nearly 1,000 cases, mostly among unvaccinated children. It is the largest outbreak since theCenters for Disease Control and Prevention declared measles eradicated more than 25 years ago.

“The United States is experiencing the highest numbers of measles cases, outbreaks, hospitalizations and deaths in more than 30 years, driven by populations with low vaccination rates,” said California Public Health Officer Dr. Erica Pan in a statement earlier this month. “We all need to work together to share the medical evidence, benefits, and safety of vaccines to provide families the information they need to protect children and our communities."

Containment comes with high costs

Investigating any communicable disease is time-intensive and expensive. The first three measles cases reported in L.A. County this year cost an estimated $231,000, according to a health department analysis.

Why does it cost so much? Because a disease investigation often requires a legion of public health nurses, physicians, epidemiologists and laboratory scientists to follow-up with hundreds of contacts, Balter said.

That includes sometimes visiting homes or exposure sites. For example, a recent exposure at a daycare required nurses to wring urine out of used diapers to test babies for measles. County health workers monitored 246 people who had been exposed to those first three measles cases — and the work is ongoing.

On Feb. 19, the county reported its fourth measles case. All of them were related to international travel. Other cases in California also have primarily been related to travel either internationally or to states where there are outbreaks. An unvaccinated child in Napa County contracted measles in January after traveling to South Carolina.

Riverside County health officials reported one measles case where the child had not traveled recently, and Shasta County health officials suspect their first case could be related to travel in Southern California but are waiting for DNA testing for confirmation.

Orange County reported two travel-related cases this year.

Health departments have fewer resources, more cases

Local health departments rely heavily on federal funding to prevent the spread of infectious diseases, but last year, the Trump administration slashed nearly $1 billion of public health funding from California. This year it attempted to claw back another $600 million from California and three other Democratic states.

Pending lawsuits froze the cuts, but local health departments are treating the money as a lost cause because they cannot bear the financial risk if a judge eventually rules in favor of the Trump administration.

Consequently, health departments closed clinics, terminated programs and laid off dozens of workers.

“What we can do with less is less unfortunately,” Balter said. L.A. county is facing a $50 million shortfall due to federal, state and local cuts and recently closed seven public health clinics.

Health departments are also confronting decreased public confidence: The high-profile questioning of vaccine safety and effectiveness by U.S. Secretary of Health and Human Services Robert F. Kennedy Jr. has complicated public health’s struggle to contain the spread of preventable infections.

California Democratic leaders are aggressively fighting Kennedy’s direction. They sued to block the administration’s new vaccine guidelines, which stripped universal recommendation from seven childhood vaccines. They blame Kennedy and the Trump administration for “dismantling” the Centers for Disease Control and Prevention and stoking fears over debunked claims that vaccines cause autism.

The state also released its own vaccine guidelines and formed an alliance among four western states to share public health information and recommendations.

“Everything including the outbreaks, the financial cuts, the questions from the federal government that are arising are making our work very difficult,” said Dr. Regina Chinsio-Kwong, Orange County public health officer.

Twelve years ago, Orange County was the site of California’s largest measles outbreak in decades. An exposure at Disneyland from an unknown source infected 131 Californians and spread to six states, Canada and Mexico.

The outbreak, which lasted four months, spurred state lawmakers to pass some of the strictest childhood vaccine requirements in the country.

But even a single measles case requires “vast amounts of infrastructure” to contain, Chinsio-Kwong said. On average, the department identifies and monitors 100 exposed people per case. Since the start of last year, Orange County has lost $22 million in federal cuts to public health. The department is trying to protect their communicable disease surveillance work, but it gets harder with every cut.

“We're trying to prioritize our communicable disease control division,” health officer Chinsio-Kwong said. “There are a lot of different federal cuts, but we're putting that as front and center: That has to be saved no matter what.”

Measles spread in unvaccinated groups

Six hundred miles north, Shasta County is grappling with its first measles cases since 2019 and the state’s largest outbreak of the year.

In late January, a sick child visited a health clinic in Redding with measles symptoms that laboratory testing later confirmed. Health officials interviewed 278 people and identified six locations where others were exposed: a restaurant, a church basketball game, a gym, a park, Costco and the clinic.

They also identified seven other cases among family members or neighbors who were in close contact with the child.

It can take 21 days from the time of exposure for measles symptoms to develop. On Feb. 19, just before the end of that period, health officials confirmed a ninth case.

That person didn’t recognize the symptoms and visited several places while contagious, including a school, a church service, a basketball game and a clinic, said Daniel Walker, a Shasta County supervising epidemiologist. Now, the contract tracing process has started over. The communicable disease team expects to interview even more people this time.

All cases have been among children who were unvaccinated or did not know their vaccination status.

“It’s a great time to get immunized, because you can’t know when you’re next going to be exposed…especially because we’re in an outbreak situation,” Walker said.

L.A. County Sheriff Robert Luna confirmed Monday that ICE will play a role in World Cup security, but said he's been told federal agents won't conduct immigration enforcement.

He made the comments at a news conference on law enforcement's plans for the tournament, and said he'd been speaking directly with the head of Homeland Security in the Los Angeles area.

"There will be federal agents," Luna said. " Because it's gonna take all of us to make sure that all the venues, the scoped and unscoped events, are secure."

SoFi Stadium is set to host eight tournament matches, including the U.S. team opener against Paraguay on June 12. Los Angeles will also host a historic match three days later when Iran is set to take the field in Inglewood, making the U.S. the first host nation in World Cup history to be at war with a participating country.

Luna said the federal government had said that civil immigration enforcement would not occur at the tournament. But he made no guarantees.

" They told us that specifically would not be occurring at any of the games. Any of that's subject to change," he said. "But I have trust that they're giving me the appropriate information because if that starts occurring, we're gonna have a whole new host of problems."

In a statement to LAist, Assistant Secretary Lauren Bis wrote that Department of Homeland Security is working with federal, state, local and international partners.

“The safety and security of the American people and the millions of visitors attending these events remain our highest priority," Bis wrote in an email. "DHS will continue leveraging every available authority, technology, and partnership to protect the Homeland while ensuring the World Cup remains safe, secure, and successful for everyone involved.”

Luna is the latest official to confirm that U.S. Immigration and Customs Enforcement will play a role in the tournament. Kathryn Schloessman, who leads L.A.'s World Cup host committee, told reporters last month that ICE would be at the World Cup, and that its presence was typical at these types of major events.

ICE has two main branches: Enforcement and Removal Operations, which detains and deports people, and Homeland Security Investigations, which conducts international criminal investigations.

Todd Lyons, the former head of ICE, said at a congressional hearing earlier this year that it would be ICE’s investigatory branch, not its enforcement division, playing a key role in World Cup security.

Still, some in L.A. aren't satisfied. The World Cup is coming to Los Angeles at exactly the year mark since immigration agents ramped up arrests in the region. Masked agents in neighborhoods across the county sparked protests and widespread fear, and ICE arrests in the L.A. area last year tripled.

SoFi Stadium workers represented by Unite Here Local 11 have threatened to strike over ICE's role in the tournament. They'll vote on whether or not to authorize a strike later this week.

California air regulators on Friday approved a contentious overhaul of the state’s carbon market, creating a program that could steer billions of dollars in free pollution permits to oil refineries and other major polluters over the objections of environmental groups, key lawmakers and three of the board’s own members.

Ten members of the California Air Resources Board voted to adopt the changes to its cap-and-invest program after two days of lengthy hearings, including a full day dedicated to hundreds of public comments.

The overhaul followed intensive lobbying by the oil industry as well as pressure from Gov. Gavin Newsom’s administration to help keep refineries operating in the state amid rising gas prices.

The approval sets up a potential budget fight in Sacramento. The Legislative Analyst’s Office projects that quarterly auction revenue for state climate programs will drop from roughly $4 billion a year to about $2 billion under the new overhaul.

Such a shortfall would effectively zero out programs lawmakers spent last year fighting to fund: affordable housing, public transit, drinking water in low-income communities and pollution monitoring in California’s most polluted neighborhoods.

The governor’s office praised the measure as a compromise that balanced economic uncertainty with the state’s climate goals. Refinery closures and the Iran-Israel war have driven average California gas prices above $6 a gallon.

Newsom, in a statement, used the moment to draw a contrast with President Donald Trump.

“While Trump sows ongoing chaos and uncertainty, California is staying focused by protecting our economy, safeguarding public health, and doubling down on the clean energy future all Californians deserve,” he said.

Environmentalists warned the changes to the program amount to a giveaway to the fossil fuel industry that weakens California’s only program setting a firm cap on greenhouse gas emissions.

Katelyn Roedner Sutter, California senior director for the Environmental Defense Fund, called the decision “deeply misguided” for prioritizing polluters over communities.

“Newsom’s air regulators are handing billions to oil executives at the expense of our climate, health, and affordability for working families in a rushed process that has shortchanged meaningful public participation,” said Bahram Fazeli, policy director at Communities for a Better Environment.

How the program works — and what changes

California’s 13-year-old carbon market forces major polluters to buy permits while the state lowers the overall cap each year. Friday’s vote will reduce those permits – and creates a new subsidy program carved out of the market.

The program, which may still see changes, could make available a new pool of free pollution permits available to industry valued at as much as $4 billion. Companies that pledge to invest in clean energy and efficiency may qualify for the permits in exchange for investments in clean energy.

The pool will be capped at 118.3 million permits — the same number the air board has said must come off the market for California to hit its 2030 climate target. Environmentalists say the proposal risks wiping out those reductions.

Half are reserved for the fossil fuel sector. A recent Berkeley analysis, by the chair of an independent committee that oversees the carbon market, found refineries could end up with more free permits than they need to cover their emissions.

The air board has defended the design. Officials say the credits will go only to companies undertaking decarbonization projects, will be limited and temporary and can be clawed back if companies misuse them. The plan, they say, is meant to keep California refineries operating at a time of mounting closures and global market pressure. According to air regulators, the amended program will spur clean-energy investment as Trump cuts federal support.

Here's what you should know about the vote totals currently released:

Keep in mind that June 9 will be the final day for votes postmarked by June 2 to arrive at county elections offices, so the bottom line on the vote totals won't be known until then.

In L.A. County, the combined tallied votes as of Sunday add up to about 10% of registered voters.

In Orange County, the current tallies represent about 22% of registered voters.

How vote counts will be released

I thought it was an election NIGHT?

That hasn't been true in quite a while. It takes a while to get results because after the initial tallies on election night, there are still many, many votes to count and more mail-in ballots are usually arriving.

Here’s what we know so far:

L.A. County turnout

Los Angeles County has more than 5.8 million registered voters. As of Sunday, May 31:

• 580,720 ballots have been processed
• 95% voted by mail
• 5% voted in person

What's next:

• We'll know more on election night and the following days how many ballot remain to be counted.
• Has your ballot been tallied yet? You can track the status of your ballot here.

Orange County turnout

Orange County has more than 1.8 million registered voters. As of Sunday, May 31:

• 401,865 ballots have been processed
• 95% voted by mail
• 5% voted in person

What's next:

• We'll know more on election night and the following days how many ballot remain to be counted.
• Has your ballot been tallied yet? You can track the status of your ballot here.

Expected total turnout

Political Data Inc. is tracking ballot returns across California and in some high-profile races.

As of midday Monday, turnout statewide was at 16%. While Democrats outnumber Republicans statewide by almost double, Republicans have returned more ballots pre-election (21% of their voters compared to 16% for Democrats).

Why election day has turned into ballot-counting month

Because of the increasing use of vote-by-mail ballots, the vote count has gotten longer, according to the California Voter Foundation. In an analysis, the organization found:

• In November 2004, more than 80% of votes were counted within two days of Election Day, with 32.6% voting by mail. 
• In June 2022, about 50% of ballots were counted within two days of Election Day, with more than 90% of people voting by mail. 
• In November 2024, 66% of votes were counted within the first two days of Election Day, with 81% of the vote by mail.

Election officials must physically open mail-in ballots and verify signatures.

Kim Alexander, president of the California Voter Foundation, recently wrote about the ripple effect of turning in mail-in ballots by hand or in drop boxes on election day. She wrote for our partner newsroom CalMatters:

"We turn in ballots in envelopes on Election Day that take time and care to process and cannot be processed until after Election Day. Processing these ballots — which account for as much as a quarter of all ballots cast — creates a bottleneck I like to call 'the pig in the python effect'. It prevents counties from doing other tasks they need to do to certify the results."

The buzz on college campuses is that AI is disrupting the job market for young college graduates.

But new research from the Federal Reserve Bank of New York finds that the culprit may be something else: remote work.

An analysis of federal employment data, paired with a deep dive into the flexible work arrangements at one unnamed Fortune 500 tech company, reveals that companies are less likely to hire recent college grads into occupations that can be done remotely.

Researchers speculate that employers are reluctant to put such workers in a setting where it's harder to absorb lessons from coworkers.

The researchers found the unemployment rate among younger college grads — those under the age of 29 — rose 20% after the pandemic, while unemployment among older college grads fell slightly.

The study compares unemployment rates pre-pandemic, from 2017 to 2019, with unemployment rates after the pandemic, from 2022 to 2024.

Unemployment rose as remote work grew fourfold, the researchers write. "Our analysis suggests that these trends are related, with remote work making it more difficult for managers to train and mentor new employees."

Remote work leads to less feedback on the job

The research began with a look at how much feedback software engineers at a Fortune 500 tech company were getting, says Emma Harrington, an assistant professor of economics at the University of Virginia and one of the authors of the report.

"What we saw was this pretty striking pattern that software engineers got about 20% more feedback if they were sitting near their colleagues than if they were distant from them," she says, adding that that was true even before the pandemic.

But after the pandemic, feedback plummeted.

"And that really hit young workers much harder," says Harrington. "It was these people who had the most to learn that really saw this deficit in feedback."

The researchers then looked deeper into who was getting hired at the tech firm. Turns out, as the company embraced remote work, they switched away from hiring younger people.

"So they used to hire a bunch of new grads for their software engineering jobs," Harrington says. "Then they shifted really towards hiring much older people, like a decade older on average."

Later, the company pivoted again, implementing what Harrington calls a "pretty aggressive" return-to-office policy. At that point, the company resumed hiring new graduates.

"So [there was] some sense that these problems with mentorship were translating into whom this firm was deciding to hire," she says.

A look at the broader economy

The researchers then wanted to see if what was happening at that single tech company was playing out in the broader economy.

Using a widely-used index that measures how feasible it is to do a job from home, the team divided all occupations into two categories: "remotable," which included software engineering, and "non-remotable," which included mechanical engineering.

They found the gap in unemployment between recent graduates and older workers was significantly higher in "remotable" jobs than in jobs that have to be done in person.

The unemployment rate for younger grads in "remotable" jobs jumped by almost a full percentage point after the pandemic, while the unemployment rate among older grads fell marginally.

They concluded that remote work explained nearly two-thirds of the rise in unemployment among young graduates during this period.

"This relative increase in young people's unemployment coincided with the pandemic and has remained elevated since then, as have rates of remote work," the researchers write.

AI isn't disrupting so many jobs for recent college grads — yet

To see how the rise of AI chatbots may have contributed to rising unemployment among the younger set, the researchers used another index that divides occupations into those more exposed to AI, such as engineering and accounting, and those less exposed, such as teaching and nursing.

They found exposure to AI didn't explain the divergence in unemployment rates in the 2022-24 time period. Remote workflows were much more of a driving force, Harrington says, while emphasizing that this could change.

"It's always hard to make guesses about what's going to happen with generative AI," she says. "It's certainly possible that this story could really change over the next few years."

Researchers at the London School of Economics have reached a similar conclusion — that remote work is having a clearer impact on early-career hiring than AI — in a working paper examining new hires in the U.S., the U.K., Canada and Australia.

Regardless of the cause, the New York Fed report warns that a high unemployment rate among young college grads is concerning.

"Early-career experiences can have lasting consequences," the researchers write. "Research finds that individuals who began looking for jobs in slacker labor markets tend to have lower earnings and slower career progression relative to comparable peers who began their job search in better market conditions."
