The most important stories for you to know today
  • CA among states most often reporting cases
    A swarm of mosquitos flies against a green background.
    Mosquitoes that transmit Dengue have been found throughout California.

    Topline:

    Dengue has recently shown up in California, Florida and Texas, places where it's not usually found. Experts fear that climate change and no vaccine could help it spread further across North America.

    Cases on the climb: The CDC logged 3,700 infections last year, with 105 cases reported in California, Texas, and Florida-warning continued growing risk with big spikes also seen in Latin America and Asia.

    What to know: Dengue is spread by Aedes mosquito bites. Most cases are mild, but severe symptoms like bleeding from the nose or mouth, intense stomach pain, vomiting, and swelling and death can occur.

    As summer ushers in peak mosquito season, health and vector control officials are bracing for the possibility of another year of historic rates of dengue. And with climate change, the lack of an effective vaccine, and federal research cuts, they worry the disease will become endemic to a larger swath of North America.

    About 3,700 new dengue infections were reported last year in the contiguous United States, up from about 2,050 in 2023, according to the Centers for Disease Control and Prevention. All of last year’s cases were acquired abroad, except for 105 cases contracted in California, Florida, or Texas. The CDC issued a health alert in March warning of the ongoing risk of dengue infection.

    “I think dengue is here with us to stay,” said infectious disease specialist Michael Ben-Aderet, associate medical director of hospital epidemiology at Cedars-Sinai in Los Angeles, about dengue becoming a new normal in the U.S. “These mosquitoes aren't going anywhere.”

    Dengue is endemic — a label health officials assign when diseases appear consistently in a region — in many warmer parts of the world, including Latin America, India, and Southeast Asia. Dengue cases increased markedly last year in many of those places, especially in Central and South America.

    The disease, which can spread when people are bitten by infected Aedes mosquitoes, was not common in the contiguous United States for much of the last century. Today, most locally acquired (meaning unrelated to travel) dengue cases in the U.S. happen in Puerto Rico, which saw a sharp increase in 2024, triggering a local public health emergency.

    Most people who contract dengue don’t get sick. But in some people symptoms are severe: bleeding from the nose or mouth, intense stomach pain, vomiting, and swelling. Occasionally, dengue causes death.

    California offers a case study in how dengue is spreading in the U.S. The Aedes aegypti and Aedes albopictus mosquitoes that transmit dengue weren’t known to be in the state 25 years ago. They are now found in 25 counties and more than 400 cities and unincorporated communities, mostly in Southern California and the Central Valley.

    The spread of the mosquitoes is concerning because their presence increases the likelihood of disease transmission, said Steve Abshier, president of the Mosquito and Vector Control Association of California.

    From 2016 through 2022, there were an average of 136 new dengue cases a year in California, each case most likely brought to the state by someone who had traveled and been infected elsewhere. In 2023, there were about 250 new cases, including two acquired locally.

    In 2024, California saw 725 new dengue cases, including 18 acquired locally, state data shows.

    Climate change could contribute to growth in the Aedes mosquitoes’ population, Ben-Aderet said. These mosquitoes survive best in warm urban areas, often biting during the daytime. Locally acquired infections often occur when someone catches dengue during travel, then comes home and is bitten by an Aedes mosquito that bites and infects another person.

    “They've just been spreading like wildfire throughout California,” Ben-Aderet said.

    Dengue presents a challenge to the many primary care doctors who have never seen it. Ben-Aderet said doctors who suspect dengue should obtain a detailed travel history from their patients, but confirming the diagnosis is not always quick.

    “There's no easy test for it,” he said. “The only test that we have for dengue is antibody tests.” He added that “most labs probably aren't doing it commercially, so it's usually like a send-out test from most labs. So you really have to suspect someone has dengue.”

    Best practices for avoiding dengue include eliminating any standing pools of water on a property — even small pools — and using mosquito repellent, Abshier said. Limiting activity at dusk and dawn, when mosquitoes bite most often, can also help.

    Efforts to combat dengue in California became even more complicated this year after wildfires ripped through Los Angeles. The fires occurred in a hot spot for mosquito-borne illnesses. San Gabriel Valley Mosquito and Vector Control District officials have worked for months to treat more than 1,400 unmaintained swimming pools left in the wake of fire, removing potential breeding grounds for mosquitoes.

    San Gabriel vector control officials have used local and state resources to treat the pools, said district spokesperson Anais Medina Diaz. They have applied for reimbursement from the Federal Emergency Management Agency, which has not historically paid for vector control efforts following wildfires.

    In California, vector control agencies are often primarily funded by local taxes and fees on property owners.

    Some officials are pursuing the novel method of releasing sterilized Aedes mosquitoes to reduce the problem. That may prove effective, but deploying the method in a large number of areas would be costly and would require a massive effort at the state level, Abshier said. Meanwhile, the federal government is pulling back on interventions: Several outlets have reported that the National Institutes of Health will stop funding new climate change-related research, which could include work on dengue.

    This year, reported rates of dengue in much of the Americas have declined significantly from 2024. But the trend in the United States likely won’t be clear until later in the year, after the summer mosquito season ends.

    Health and vector control researchers aren't sure how bad it will get in California. Some say there may be limited outbreaks, while others predict dengue could get much worse. Sujan Shresta, a professor and infectious disease researcher at the La Jolla Institute for Immunology, said other places, like Nepal, experienced relatively few cases of dengue in the recent past but now regularly see large outbreaks.

    There is a vaccine for children, but it faces discontinuation from a lack of global demand. Two other dengue vaccines are unavailable in the United States. Shresta’s lab is hard at work on an effective, safe vaccine for dengue. She hopes to release results from animal testing in a year or so; if the results are positive, human trials could be possible in about two years.

    “If there's no good vaccine, no good antivirals, this will be a dengue-endemic country,” she said.

  • Supreme Court seems inclined to rule against Trump

    Topline:

    A majority of the Supreme Court justices seemed skeptical of the Trump administration's argument on birthright citizenship yesterday and appeared ready to rule in favor of upholding automatic citizenship for babies born on U.S. soil.

    Keep reading... for details on the questions posed to lawyers, including conservative justices tough questions for President Donald Trump's solicitor general, D. John Sauer.

    A majority of the Supreme Court justices seemed skeptical of the Trump administration's argument on birthright citizenship Wednesday and appeared ready to rule in favor of upholding automatic citizenship for babies born on U.S. soil.

    That included multiple conservative justices, who had tough questions for Trump's solicitor general, D. John Sauer. Sauer argued the government's case against birthright citizenship, the practice enshrined in the 14th Amendment in the Constitution, which became law in 1868.

    It states: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside."

    Sauer, however, asserted that contrary to the law as understood for 160 years, the 14th Amendment does not confer automatic citizenship on every baby born in the U.S. He told the court that the true meaning of the amendment was to grant citizenship to former slaves and their children, no more. And, therefore, President Trump was well within his rights when he signed an executive order barring citizenship for children born in this country to parents who are illegally here, or who are here legally, but on long-term visas.

    But Chief Justice John Roberts was doubtful about that executive order.

    "The examples you give to support that strike me as very quirky," Roberts told Sauer. "And then you expand it to a whole class of illegal aliens," he continued. "I'm not quite sure how you can get to that big group from such tiny and, sort of, idiosyncratic examples."

    "We're in a new world now," Sauer contended. "A billion people are one plane ride away from having a child who's a U.S. citizen."

    "It's a new world," Roberts replied, but "it's the same Constitution."

    Justice Neil Gorsuch noted that the Trump executive order focuses on parents, but the 14th Amendment focuses on birthright for the child. He asked: how would you know who the father is, or the mother? What if they're unmarried? Whose house do they live in?

    Justice Amy Coney Barrett questioned the practicality of the Trump proposal.

    "How would it work?" she asked. "How would you adjudicate these cases? You're not going to know at the time of birth whether they have the intent to stay or not, including U.S. citizens by the way."

    Justice Ketanji Brown Jackson wondered, "So [are] we bringing pregnant women in for depositions? What are we doing to figure this out?"

    The justices also grilled Sauer about the landmark 1898 case of Wong Kim Ark, in which the U.S. Supreme Court ruled that Wong had birthright citizenship, because he was born in the United States. Sauer, however, maintained that Wong was only given birthright citizenship because his parents were legally domiciled in the United States.

    "I think even your brief concedes that the position you're taking now is a revisionist one with respect to a substantial part of our history," Justice Elena Kagan said. "That's, in part, because of Wong Kim Ark and the way people have read that case ever since then."

    Challenging the Trump birthright plan, the American Civil Liberties Union's Cecillia Wang told the Supreme Court that the 14th Amendment was enacted after the Civil War in order to have a universal rule of citizenship, subject to a closed set of exceptions, and that the birthright applies to all children born on U.S. soil.

    "We can't take the current administration's policy considerations into account to try to re-engineer and radically re-interpret the original meaning of the 14th Amendment," Wang argued.

    However, in reference to current perceived immigration problems versus those that existed at the time the 14th Amendment was enacted, Kagan posited: "What do we do if we think we have a new problem that didn't exist at the time of the 14th Amendment?"

    Justice Brett Kavanaugh followed up, asking whether the provisions of the 14th Amendment are frozen in place.

    Yes, replied Wang, because the framers of it were intent on putting the citizenship question out of the reach of Congress.

    The decision, expected by this summer, will almost certainly result in a historic ruling, and Trump himself made his mark at the court Wednesday morning.

    He became the first sitting president known to attend oral arguments, signaling the importance of this issue to him personally.

    After leaving the courtroom before the arguments were over, he wrote on Truth Social, "We are the only Country in the World STUPID enough to allow 'Birthright' Citizenship!" In fact, roughly three dozen countries offer it.

    Trump arrived about 10 minutes before the arguments began, listened to Sauer field the justices' questions for a little over an hour and then left a few minutes after Wang began to make her case.

    Outside the court, dozens of people rallied in support of birthright citizenship

    Volunteers with the ACLU, joined by immigrant rights organizations like CASA and the League of United Latin American Citizens, handed out fliers that read "protect birthright citizenship" and "14th Amendment."

    "We're all out here to protect the fundamental right of birthright citizenship. It's written in the 14th Amendment," said Anu Joshi, a staff member of the ACLU. "It's what makes us America."

    Among the crowd were several people who were citizens by birthright themselves.

    "I am a birthright citizen so this hits really, really close to home because without birthright citizenship I wouldn't even have my citizenship in the United States," said Stephanie Sanchez, a first-generation Mexican-American who came to the rally. "Here I am representing my community and fighting back."

    After the arguments, ACLU Executive Director Anthony Romero told the crowd he felt confident in the way the arguments played out inside.

    "We are fighting for the heart and soul of this country. The fight to protect birthright citizenship is about our neighbors, our families, our kids. It's not about the past, it's about the future," he said. "We will only accept what is just and what is right."

    Largely absent from the crowd were proponents of the president's position.

  • Trades workers say they're owed raises
    Diverse students walk on a concrete walkway with a glass pyramid in the background.
    Cal State Long Beach is one of the 23 CSU campuses where Teamsters-represented workers held a strike last month.

    Topline:

    The California Public Employment Relations Board (has issued a formal complaint against California State University trustees over the system’s alleged refusal to give raises to trades workers. The complaint follows a statewide strike earlier this year, in which workers at every campus walked off the job.

    Why it matters: Teamsters Local 2010 represents 1,100 plumbers, electricians, HVAC techs, locksmiths and other building maintenance staff who work across the CSU system. A formal complaint from the Public Employment Relations Board means the two parties must resolve the dispute in a formal hearing process.

    The backstory:  According to Teamsters Local 2010, union members won wage increases in 2024 “after nearly three decades of stagnation.” That year, the union was on the verge of striking alongside the system's faculty, but it reached a last-minute deal with the CSU. The union has filed an unfair labor practice charge against the system, arguing that the CSU refused to honor contractually obligated raises and step increases for its members.

    What the CSU says: The CSU maintains that conditions described in its collective bargaining agreement with the union — which “tied certain salary increases to the receipt of new, unallocated, ongoing state budget funding” — were not met.

    What’s next: In an emailed statement, spokesperson Amy Bentley-Smith said the CSU welcomes “the opportunity to present the facts of this case before an administrative law judge.” After the formal hearing, the state board will propose a resolution to the dispute.
