COVID 'razor blade throat' rises as new subvariant spreads in California

• COVID rising in wastewater in parts of California
• New subvariant, ‘Nimbus,’ increasingly dominant nationally
• Concerns rise about Trump’s appointees making vaccine access more difficult

COVID-19 appears to be on the rise in some parts of California as a new, highly contagious subvariant — featuring “razor blade throat” symptoms overseas — is becoming increasingly dominant.

Nicknamed “Nimbus,” the new subvariant NB.1.8.1 has been described in news reports in China as having more obvious signs of “razor blade throat” — what patients describe as feeling like their throats are studded with razor blades.

Although “razor blade throat” may seem like a new term, the description of incredibly painful sore throats associated with COVID-19 has emerged before in the United States, like having a throat that feels like it’s covered with shards of glass. But the increased attention to this symptom comes as the Nimbus subvariant has caused surges of COVID-19 in other countries.

“Before Omicron, I think most people presented with the usual loss of taste and smell as the predominant symptom and shortness of breath,” said Dr. Peter Chin-Hong, a UC San Francisco infectious-disease expert. But as COVID has become less likely to require hospitalization, “people are focusing on these other aspects of symptoms,” such as an extraordinarily painful sore throat.

Part of the Omicron family, Nimbus is now one of the most dominant coronavirus subvariants nationally. For the two-week period that ended June 7, Nimbus comprised an estimated 37% of the nation’s coronavirus samples, now roughly even with the subvariant LP.8.1, probably responsible for 38% of circulating virus. LP.8.1 has been dominant over the past few months, according to the Centers for Disease Control and Prevention.

The Nimbus subvariant has also been increasing since May in California, the state Department of Public Health said in an email to the Los Angeles Times. Projections suggest the Nimbus subvariant comprises 55% of circulating virus in California, up from observations of just 2% in April, the agency said Friday.

“We are seeing some indicators of increased COVID-19 activity, including the rise of the NB.1.8.1 variant, elevated coronavirus levels in wastewater, and an uptick in the test positivity rate,” Dr. Elizabeth Hudson, regional chief of infectious diseases for Kaiser Permanente Southern California, wrote in an email to The Times.

“Wastewater surveillance across Southern California shows variability: Santa Barbara watersheds are reporting moderate-to-high levels, Ventura and Los Angeles counties are seeing low-to-moderate levels, Riverside is reporting low levels, while San Bernardino is experiencing high activity,” Hudson said.

While viral concentrations remain relatively low, Los Angeles County has observed an increase in coronavirus levels in sewage, the local Department of Public Health told The Times. For the week that ended May 30 — the most recent available — viral levels in wastewater rose by 13% versus a comparable period several weeks earlier.

In addition, there is a slight increase in the rate in which COVID surveillance tests are turning up positive in L.A. County. For the most recent week, 5% of COVID surveillance tests showed positive results for infection, up from 3.8% in early May. COVID-related visits to the emergency room remain low in Los Angeles County.

There were still low rates of COVID-19 illness in San Francisco, the local Department of Public Health said.

Yet coronavirus levels in wastewater in Northern California’s most populous county, Santa Clara County, are starting to increase, “just as they have over past summers,” the local Public Health Department said in an email to The Times. As of Friday, coronavirus levels in the sewershed of San José was considered “high.” Viral levels were “medium” in Palo Alto and “low” in Sunnyvale. Nimbus is the most common subvariant in the county.

Across California, coronavirus levels in wastewater are at a “medium” level; the last time viral levels were consistently “low” was in April, according to the state Department of Public Health’s website.

“Future seasonal increases in disease levels are likely,” the California Department of Public Health said in an email to The Times Friday.

The uptick in COVID comes as many medical professional organizations and some state and local health officials are objecting to the Trump administration’s recent moves on vaccine policy, which some experts fear will make it more difficult for people to get vaccinated against COVID-19 and other diseases.

Federal officials in May weakened the CDC’s official recommendations from recommending the COVID vaccine to everyone age 6 months and up. The CDC now offers “no guidance” on whether healthy pregnant women should get the COVID vaccine, and now asks that parents of healthy children talk with a healthcare provider before asking that their kids get inoculated.

The American College of Obstetricians and Gynecologists issued a rebuke of the changing vaccine recommendations for pregnant women, accusing the U.S. Department of Health and Human Services — led by the vaccine-skeptic secretary, Robert F. Kennedy Jr. — of “propagating misinformation.” The American Pharmacists Assn. wrote that dropping the vaccine recommendation for pregnant women did “not appear to be based on the scientific evidence provided over the last few years.”

And an open letter by 30 organizations specializing in health — including the American Medical Assn. — said that “we must continue to prioritize high levels of COVID-19 vaccine coverage in pregnant patients to protect them and their infants after birth.”

Chin-Hong said he recommends pregnant women get vaccinated “one million percent.”

“The data are incredibly clear that pregnant women do have a higher rate of complications, hospitalization and premature births when they did not get vaccinated [against COVID] compared to the ones that did,” said Dr. Yvonne Maldonado, an infectious-disease expert at Stanford University. The vaccines also help newborns, as antibodies generated by the mom-to-be cross the placenta, and can protect the newborn for a certain number of months, she said.

That’s essential protection, given that newborns can’t be vaccinated under 6 months of age, Maldonado said. If newborns are infected, they have relatively high rates of hospitalization — as high as those age 65 and over, Maldonado said.

Then, last week, Kennedy abruptly fired all members of a highly influential committee that advises the CDC on vaccine policy. In an op-ed to the Wall Street Journal, Kennedy criticized the previous members of the Advisory Committee on Immunization Practices, founded in 1964, as being “plagued with persistent conflicts of interest and has become little more than a rubber stamp for any vaccine.”

Maldonado, a professor in pediatric infectious diseases and epidemiology, was one of the fired vaccine advisors. She called their mass dismissal unprecedented in the history of the ACIP.

“We are absolutely in uncharted territory here,” Maldonado said. “I think it’s going to be really hard to understand what vaccines are going to go forward. … They’re also going to review the entire vaccination schedule.”

In general, routine review of vaccine schedules are a good thing, and prior reviews have concluded that the current recommended shots are safe and effective, Maldonado said. But the criteria being circulated by recently appointed federal officials “could actually wind up refusing to recommend, say, measles vaccine or HPV vaccine, because I’ve seen some of the misinformation that has been out there about some of these vaccines. …

“And if any of that is accepted as truth, we could wind up losing some of these vaccines,” Maldonado said.

“The question, then, is: ‘Would those vaccines disappear?’ … Hard to know,” she said. But it’s also possible that federal officials could begin to stop paying for certain vaccines to be administered to children of low-income families.

She rejected Kennedy’s characterization of the committee as a rubber stamp for vaccine makers. “Generally, a decision to not pursue a vaccine happens usually well before anything gets to a vote,” Maldonado said.

A joint statement by the governors of California, Oregon and Washington condemned Kennedy’s dismissal of the vaccine advisors as “deeply troubling for the health of the nation” and defended the fired vaccine advisors as having been “carefully screened for major conflicts of interest.”

“We have grave concerns about the integrity and transparency of upcoming federal vaccine recommendations and will continue to collaborate to ensure that science and sound medicine prevail to prevent any loss of life,” Gov. Gavin Newsom said in a statement Thursday.

Traditionally, the advisory committee’s recommendations on who should get vaccinated were adopted by the director of the CDC.

“It was one of the most depressing weeks in American health … a dark period for everyone right now, and demoralizing,” said Chin-Hong, of UC San Francisco. “It’s very destabilizing.”

The American Academy of Pediatrics called the purge of the vaccine advisors “an escalating effort by the administration to silence independent medical expertise and stoke distrust in lifesaving vaccines.” Kennedy’s handpicked replacements include people known for their criticism of vaccines, the Associated Press reported.

The mass firing “likely puts vaccine access and insurance coverage at serious risk,” the L.A. County Department of Public Health said in a statement. “It corrodes trust in the recommended schedule for vaccines, not only by the public, but by medical providers who rely on the ACIP for science-based, apolitical guidance.”

The departments of public health for California, Oregon and Washington said they “continue to recommend all individuals age 6 months and older should have access and the choice to receive currently authorized COVID-19 vaccines, with an emphasis on protecting higher risk individuals, such as infants and toddlers, pregnant individuals, and others with risks for serious disease.”

The L.A. County Department of Public Health said in a statement that, “at this time in Los Angeles County, current vaccine recommendations for persons aged 6 months and older to receive the COVID-19 vaccine remain in effect and insurance coverage for COVID-19 vaccines is still in place.”

Diablo Canyon clears last California permit hurdle to keep running

Diablo Canyon clears last California permit hurdle to keep running

Central Coast Water authorities approved waste discharge permits for Diablo Canyon nuclear plant Thursday, making it nearly certain it will remain running through 2030, and potentially through 2045.

The Pacific Gas & Electric-owned plant was originally supposed to shut down in 2025, but lawmakers extended that deadline by five years in 2022, fearing power shortages if a plant that provides about 9 percent the state’s electricity were to shut off.

In December, Diablo Canyon received a key permit from the California Coastal Commission through an agreement that involved PG&E giving up about 12,000 acres of nearby land for conservation in exchange for the loss of marine life caused by the plant’s operations.

Today’s 6-0 vote by the Central Coast Regional Water Board approved PG&E’s plans to limit discharges of pollutants into the water and continue to run its “once-through cooling system.” The cooling technology flushes ocean water through the plant to absorb heat and discharges it, killing what the Coastal Commission estimated to be two billion fish each year.

The board also granted the plant a certification under the Clean Water Act, the last state regulatory hurdle the facility needed to clear before the federal Nuclear Regulatory Commission (NRC) is allowed to renew its permit through 2045.

The new regional water board permit made several changes since the last one was issued in 1990. One was a first-time limit on the chemical tributyltin-10, a toxic, internationally-banned compound added to paint to prevent organisms from growing on ship hulls.

Additional changes stemmed from a 2025 Supreme Court ruling that said if pollutant permits like this one impose specific water quality requirements, they must also specify how to meet them.

The plant’s biggest water quality impact is the heated water it discharges into the ocean, and that part of the permit remains unchanged. Radioactive waste from the plant is regulated not by the state but by the NRC.

California state law only allows the plant to remain open to 2030, but some lawmakers and regulators have already expressed interest in another extension given growing electricity demand and the plant’s role in providing carbon-free power to the grid.

Some board members raised concerns about granting a certification that would allow the NRC to reauthorize the plant’s permits through 2045.

“There’s every reason to think the California entities responsible for making the decision about continuing operation, namely the California [Independent System Operator] and the Energy Commission, all of them are sort of leaning toward continuing to operate this facility,” said boardmember Dominic Roques. “I’d like us to be consistent with state law at least, and imply that we are consistent with ending operation at five years.”

Other board members noted that regulators could revisit the permits in five years or sooner if state and federal laws changes, and the board ultimately approved the permit.

Deadly bird flu found in California elephant seals for the first time

Deadly bird flu found in California elephant seals for the first time

The H5N1 bird flu virus that devastated South American elephant seal populations has been confirmed in seals at California’s Año Nuevo State Park, researchers from UC Davis and UC Santa Cruz announced Wednesday.

The virus has ravaged wild, commercial and domestic animals across the globe and was found last week in seven weaned pups. The confirmation came from the U.S. Department of Agriculture’s National Veterinary Services Laboratory in Ames, Iowa.

“This is exceptionally rapid detection of an outbreak in free-ranging marine mammals,” said Professor Christine Johnson, director of the Institute for Pandemic Insights at UC Davis’ Weill School of Veterinary Medicine. “We have most likely identified the very first cases here because of coordinated teams that have been on high alert with active surveillance for this disease for some time.”

Since last week, when researchers began noticing neurological and respoiratory signs of the disease in some animals, 30 seals have died, said Roxanne Beltran, a professor of ecology and evolutionary biology at UC Santa Cruz. Twenty-nine were weaned pups and the other was an adult male. The team has so far confirmed the virus in only seven of the dead pups.

Infected animals often have tremors convulsions, seizures and muscle weakness, Johnson said.

Beltran said teams from UC Santa Cruz, UC Davis and California State Parks monitor the animals 260 days of the year, “including every day from December 15 to March 1” when the animals typically come ashore to breed, give birth and nurse.

The concerning behavior and deaths were first noticed Feb. 19.

“This is one of the most well-studied elephant seal colonies on the planet,” she said. “We know the seals so well that it’s very obvious to us when something is abnormal. And so my team was out that morning and we observed abnormal behaviors in seals and increased mortality that we had not seen the day before in those exact same locations. So we were very confident that we caught the beginning of this outbreak.”

In late 2022, the virus decimated southern elephant seal populations in South America and several sub-Antarctic Islands. At some colonies in Argentina, 97% of pups died, while on South Georgia Island, researchers reported a 47% decline in breeding females between 2022 and 2024. Researchers believe tens of thousands of animals died.

More than 30,000 sea lions in Peru and Chile died between 2022 and 2024. In Argentina, roughly 1,300 sea lions and fur seals perished.

At the time, researchers were not sure why northern Pacific populations were not infected, but suspected previous or milder strains of the virus conferred some immunity.

The virus is better known in the U.S. for sweeping through the nation’s dairy herds, where it infected dozens of dairy workers, millions of cows and thousands of wild, feral and domestic mammals. It’s also been found in wild birds and killed millions of commercial chickens, geese and ducks.

Two Americans have died from the virus since 2024, and 71 have been infected. The vast majority were dairy or commercial poultry workers. One death was that of a Louisiana man who had underlying conditions and was believed to have been exposed via backyard poultry or wild birds.

Scientists at UC Santa Cruz and UC Davis increased their surveillance of the elephant seals in Año Nuevo in recent years. The catastrophic effect of the disease prompted worry that it would spread to California elephant seals, said Beltran, whose lab leads UC Santa Cruz’s northern elephant seal research program at Año Nuevo.

Johnson, the UC Davis researcher, said the team has been working with stranding networks across the Pacific region for several years — sampling the tissue of birds, elephant seals and other marine mammals. They have not seen the virus in other California marine mammals. Two previous outbreaks of bird flu in U.S. marine mammals occurred in Maine in 2022 and Washington in 2023, affecting gray and harbor seals.

The virus in the animals has not yet been fully sequenced, so it’s unclear how the animals were exposed.

“We think the transmission is actually from dead and dying sea birds” living among the sea lions, Johnson said. “But we’ll certainly be investigating if there’s any mammal-to-mammal transmission.”

Genetic sequencing from southern elephant seal populations in Argentina suggested that version of the virus had acquired mutations that allowed it to pass between mammals.

The H5N1 virus was first detected in geese in China in 1996. Since then it has spread across the globe, reaching North America in 2021. The only continent where it has not been detected is Oceania.

Año Nuevo State Park, just north of Santa Cruz, is home to a colony of some 5,000 elephant seals during the winter breeding season. About 1,350 seals were on the beach when the outbreak began. Other large California colonies are located at Piedras Blancas and Point Reyes National Sea Shore. Most of those animals — roughly 900 — are weaned pups.

It’s “important to keep this in context. So far, avian influenza has affected only a small proportion of the weaned at this time, and there are still thousands of apparently healthy animals in the population,” Beltran said in a press conference.

Public access to the park has been closed and guided elephant seal tours canceled.

Health and wildlife officials urge beachgoers to keep a safe distance from wildlife and keep dogs leashed because the virus is contagious.

When slowing down can save a life: Training L.A. law enforcement to understand autism

When slowing down can save a life: Training L.A. law enforcement to understand autism

Kate Movius moved among a roomful of Los Angeles County sheriff’s deputies, passing out a pop trivia quiz and paper prism glasses.

She told them to put on the vision-distorting glasses, and to write with their nondominant hand. As they filled out the tests, Movius moved about the City of Industry classroom pounding abruptly on tables. Then came the cowbell. An aide flashed the overhead lights on and off at random. The goal was to help the deputies understand the feeling of sensory overwhelm, which many autistic people experience when incoming stimulation exceeds their capacity to process.

“So what can you do to assist somebody, or de-escalate somebody, or get information from someone who suffers from a sensory disorder?” Movius asked the rattled crowd afterward. “We can minimize sensory input. … That might be the difference between them being able to stay calm and them taking off.”

Movius, founder of the consultancy Autism Interaction Solutions, is one of a growing number of people around the U.S. working to teach law enforcement agencies to recognize autistic behaviors and ensure that encounters between neurodevelopmentally disabled people and law enforcement end safely.

She and City of Industry Mayor Cory Moss later passed out bags filled with tools donated by the city to aid interactions: a pair of noise-damping headphones to decrease auditory input, a whiteboard, a set of communication cards with words and images to point to, fidget toys to calm and distract.

“The thing about autistic behavior when it comes to law enforcement is a lot of it may look suspicious, and a lot of it may feel very disrespectful,” said Movius, who is also the parent of an autistic 25-year-old man. Responding officers, she said, “are not coming in thinking, ‘Could this be a developmentally disabled person?’ I would love for them to have that in the back of their minds.”

Autism spectrum disorder is a developmental condition that manifests differently in nearly every person who has it. Symptoms cluster around difficulties in communication, social interaction and sensory processing.

An autistic person stopped by police might hold the officer’s gaze intensely or not look at them at all. They may repeat a phrase from a movie, repeat the officer’s question or temporarily lose their ability to speak. They might flee.

All are common involuntary responses for an autistic person in a stressful situation, which a sudden encounter with law enforcement almost invariably is. To someone unfamiliar with the condition, all could be mistaken for intoxication, defiance or guilt.

Autism rates in the U.S. have increased nearly fivefold since the Centers for Disease Control began tracking diagnoses in 2000, a rise experts attribute to broadening diagnostic criteria and better efforts to identify children who have the condition.

The CDC now estimates that 1 in 31 U.S. 8-year-olds is autistic. In California, the rate is closer to 1 in 22 children.

As diverse as the autistic population is, people across the spectrum are more likely to be stopped by law enforcement than neurotypical peers.

About 15% of all people in the U.S. ages 18 to 24 have been stopped by police at some point in their lives, according to federal data. While the government doesn’t track encounters for disabled people specifically, a separate study found that 20% of autistic people ages 21 to 25 have been stopped, often after a report or officer observation of a person behaving unusually.

Some of these encounters have ended in tragedy.

In 2021, Los Angeles County sheriff’s deputies shot and permanently paralyzed a deaf autistic man after family members called 911 for help getting him to a hospital.

Isaias Cervantes, 25, had become distressed about a shopping trip and started pushing his mother, his family’s attorney said at the time. He resisted as two deputies attempted to handcuff him and one of the deputies shot him, according to a county report.

In 2024, Ryan Gainer’s family called 911 for support when the 15-year-old became agitated. Responding San Bernardino County sheriff‘s deputies shot and killed him outside his Apple Valley home.

Last year, police in Pocatello, Idaho, shot Victor Perez, 17, through a chain-link fence after the nonspeaking teenager did not heed their shouted commands. He died from his injuries in April.

As early as 2001, the FBI published a bulletin on police officers’ need to adjust their approach when interacting with autistic people.

“Officers should not interpret an autistic individual’s failure to respond to orders or questions as a lack of cooperation or as a reason for increased force,” the bulletin stated. “They also need to recognize that individuals with autism often confess to crimes that they did not commit or may respond to the last choice in a sequence presented in a question.”

But a review of multiple studies last year by Chapman University researchers found that while up to 60% of officers have been on a call involving an autistic person, only 5% to 40% had received any training on autism.

In response, universities, nonprofits and private consultants across the U.S. have developed curricula for law enforcement on how to recognize autistic behaviors and adapt accordingly.

The primary goal, Movius told deputies at November’s training session, is to slow interactions down to the greatest extent possible. Many autistic people require additional time to process auditory input and verbal responses, particularly in unfamiliar circumstances.

If at all possible, Movius said, wait 20 seconds for a response after asking a question. It may feel unnaturally long, she acknowledged. But every additional question or instruction fired in that time — what’s your name? Did you hear me? Look at me. What’s your name? — just decreases the likelihood that a person struggling to process will be able to respond at all.

Moss’ son, Brayden, then 17, was one of several teenagers and young adults with autism who spoke or wrote statements to be read to the deputies. The diversity of their speech patterns and physical mannerisms showed the breadth of the spectrum. Some were fluently verbal, while others communicated through signs and notes.

“This population is so diverse. It is so complicated. But if there’s anything that we can show [deputies] in here that will make them stop and think, ‘Hey, what if this is autism?’ … it is saving lives,” Moss said.

Some disability advocates cautioned that it takes more than isolated training sessions to ensure encounters end safely.

Judy Mark, co-founder and president of the nonprofit Disability Voices United, says she trained thousands of officers on safe autism interactions but stopped after Cervantes’ shooting. She now urges families concerned about an autistic child’s safety to call an ambulance rather than law enforcement.

“I have significant concern about these training sessions,” Mark said. “People get comfort from it, and the Sheriff’s Department can check the box.”

While not a panacea, supporters argue that a brief course is better than no preparation at all. Some years ago, Movius received a letter from a man whose profoundly autistic son slipped away as the family loaded their car at the beach. He opened the unlocked door of a police vehicle, climbed into the back and began to flail in distress.

Though surprised, the officer seated at the wheel de-escalated the situation and helped the young man find his family, the father wrote to Movius. He had just been to her training.
