The United States has confirmed its first human case of the New World screwworm, a parasitic fly larva that feeds on living tissue, raising concerns about the pest’s northward spread.
Human case linked to travel: The Centers for Disease Control and Maryland health officials confirmed the case on Aug. 4, involving a traveler returning from El Salvador. Authorities emphasized there is no evidence of local transmission and described the incident as a reminder for healthcare providers and livestock owners to remain alert.
Greater threat to livestock: While human cases are rare, screwworm infestations can be painful and even deadly if untreated. Their name comes from the screw-like way they burrow into tissue using sharp mouth hooks. The parasite poses its greatest danger to cattle, with outbreaks reported in Mexico near the U.S. border. Federal agencies are stepping up prevention efforts to stop the pest from reestablishing itself in the U.S.
The U.S. has confirmed its first human case of the New World screwworm, a flesh-eating parasite whose northward creep from South America has put the country's cattle industry on high alert in recent months.
The Centers for Disease Control and Prevention (CDC), in coordination with the Maryland Department of Health, confirmed the case on Aug. 4 in a patient who had returned from travel to El Salvador, Department of Health and Human Services spokesperson Andrew Nixon told NPR on Monday.
"This is the first human case of travel-associated New World screwworm myiasis (parasitic infestation of fly larvae) from an outbreak-affected country identified in the United States," Nixon said. "Currently, the risk to public health in the United States from this introduction is very low."
David McAllister, a spokesperson for the Maryland Department of Health, confirmed to NPR that the individual — a resident of Maryland — has recovered from the infection."The investigation confirmed there is no indication of transmission to any other individuals or animals," he wrote, calling the detection a "timely reminder for health care providers, livestock owners and others to maintain vigilance through routine monitoring."
The New World screwworm is a species of parasitic flies typically found in South America and the Caribbean, according to the CDC. Infestation occurs when fly larvae feed on the tissue or flesh of warm-blooded animals, primarily livestock and, rarely, humans.
"It's a fly, and it's the larvae that does the damage," says Max Scott, a professor in the Department of Entomology and Plant Pathology at North Carolina State University.
He says infestation in humans can be "quite painful," with high mortality rates if left untreated.
"Because once an infestation starts, that often attracts more flies that lay more eggs," he explains. "And depending where the wound is, the maggots can make their way into vulnerable tissue like the brain, or the wound can get quite big and then you get sepsis."
But, Scott says, screwworm is an insect, not a virus — so it's not contagious.
The pest poses a much bigger risk to livestock, and in the past year has been detected in cattle farms in Mexico. As the New World screwworm gets closer to the U.S. border, federal authorities have taken a series of steps to eliminate the threat — which they did successfully in the mid-20th century.

Screwworms are a type of blue-gray blowfly that look very similar to black flies found in the U.S.
The difference is that screwworms — specifically females — lay their eggs in live animals, usually in a wound or another entry point like a nasal cavity.
"The females can lay up to, like, 200 eggs at a time," Scott says. "And then when the eggs eat, they eat the animal alive."
After feeding, the larvae fall into the ground, burrow into the soil and emerge as adult screwworm flies, continuing the cycle.
The parasites are named after the screw-like way they burrow into tissue using their sharp mouth hooks. Their Latin name, Cochliomyia hominivorax, "literally means maneater," Scott says.
"It was named after a sort of unfortunate number of cases in the French penal colony of Devil's Island back in the 19th century," he explains.
Human cases are relatively rare these days, though counts are growing in some parts of South America.
The U.S. Embassy in Nicaragua said in July that it had confirmed 124 cases in the past year. In June, the U.S. Embassy in Costa Rica confirmed its seventh case since 2023 — and first human death "since at least the 1990s."
How was screwworm eradicated — and why is it spreading now?
Screwworm used to be in the U.S., mainly in Florida, Texas and, during the summer, sometimes as far north as the Dakotas, Scott says.
In the 1950s, scientists with the U.S. Department of Agriculture (USDA) pioneered a method of combating them known as the sterile insect technique, which Scott calls "one of the great success stories of the USDA of the 20th century."
Instead of using broad-spectrum insecticides, they decided to use the pest itself as a control agent. That involves mass-rearing insects inside factories, sterilizing them with radiation and then releasing them — either from the ground or, as is the case today, by "planes that fly very precise routes."
"If the females on the ground mate with a sterile male, at least with a screwworm, that's all they'll mate with … so that female won't produce any offspring," Scott says.
Through this technique, the U.S. managed to eradicate New World screwworm in 1966. Mexico followed suit in the 1970s, and Central America in the early 2000s. The U.S. also used this method to eliminate what the CDC calls a "small outbreak" in the Florida Keys in 2017.
"Over a 50-year period, screwworm was pushed back from the United States through Mexico, through Central America, to the Panama-Columbia border. That was about 20 years ago," Scott says. "It was stopped at the border and then was held for a long time until the barrier broke and screwworm came back."
Panama, Costa Rica, Nicaragua and Honduras have documented new cases in recent years, fueling concerns of a northward spread.
Scott says there are probably multiple explanations, including the movement of infested cattle and the possibility that the current strain of sterilized flies is less effective than in the past. The hope, he says, is that a bigger crop of sterilized insects will be able to contain the screwworm threat to southern Mexico, before it can reach the U.S.

What is the U.S. doing about screwworm?
The U.S. briefly halted live cattle imports from Mexico in November, after a positive case was detected there.
It lifted the ban in February but reinstated it on a month-by-month basis in May, with Agriculture Secretary Brooke Rollins citing "the continued and rapid northward spread of New World Screwworm (NWS) in Mexico." She said it had been detected in farms as far north as Oaxaca and Veracruz, some 700 miles from the U.S. border.
In the months since, the federal government has faced mounting pressure from agricultural groups worried about the threat of screwworm and its potential impact on the supply chain. In an early August letter to Rollins, they used USDA estimates to calculate that a contemporary outbreak could cause a total economic loss of more than $10.6 billion.
The USDA appears to have heard those concerns. Earlier this month, it announced sweeping plans to combat the spread of screwworm, including building the U.S.' only sterile fly production facility at an air force base in Edinburg, Texas. It says it will produce up to 300 million sterile flies per week.
Scott says at its peak, the half-century eradication campaign was run from a facility in Mexico that could produce at least 500 million sterile flies per week. It was shut down for economic reasons in 2012. There is currently only one such facility in operation, in Panama, with a maximum capacity of some 100 million flies per week.
Announcing the new initiative in Texas, Rollins did not specify when the plant will be operational, but has previously said it will take two to three years to build, Reuters reports. The USDA is also supporting a separate facility in Mexico that is slated to open in 2026.
Other steps the USDA says it will take include ramping up the hiring of USDA-employed mounted patrol officers, called "Tick Riders," to focus on border surveillance; training dogs to detect screwworm infestations in livestock at the border and investing $100 million in technologies to combat screwworm.
Agricultural groups welcomed the announcement. Zippy Duvall, president of the American Farm Bureau Federation, said in a statement that the introduction of New World screwworm in the U.S. would only exacerbate an already-volatile cattle market.
"It took decades to eradicate this parasite from within and adjacent to our borders more than a generation ago, and this is a proactive first step," he added.

The L.A. County District Attorney alleges a former Los Angeles Unified information technology employee illegally helped a tech company win more than $22 million in district contracts. Prosecutors say the case is “one of the largest money laundering schemes” in the district’s history.
The charges: According to the complaint, between 2018 and 2022 Hong “Grace” Peng worked in LAUSD’s IT department and participated in the approval and recommendation of over $22 million in payments to Innive Inc. for services primarily related to the district’s student data system. In the same time period, prosecutors allege Innive CEO Gautham Sampath paid Peng over $3 million.
Why now: According to the complaint, the district first became aware of the alleged scheme in 2022, when an LAUSD IT employee attended a conference and learned from a former colleague of a possible connection between Peng and Sampath. The district employee alerted a supervisor, who alerted the district's inspector general.
A district spokesperson sent LAist a statement Thursday saying staff will continue to participate in the investigation “as appropriate.”
What's next: Prosecutors charged Sampath with felony counts related to money laundering, “having a financial interest in a contract or purchase made in an official capacity” and “aiding and abetting a government official to have a financial interest in a contract or purchase” made in an official capacity. Peng faces two felony counts— one related to money laundering and the other with “having a financial interest in a contract or purchase made in an official capacity.” LAist has reached out to both Peng and Sampath. Peng said she had no comment. The court issued warrants for Peng and Sampath’s arrests and bail was set at $500,000 for each.

“This is the type of evidence that you just shake your head, like you can’t believe it,” said District Attorney Nathan Hochman in a recorded statement about the case.
Hochman presented multiple text messages where Peng and Sampath discussed Innive’s contracts with the district. In one, Peng said Sampath was “lucky” she was on a selection committee. When he asked why, she responded "Because you have me...lol...I broke all law for you already lol."
How did this get uncovered?

The Los Angeles Metro Board approved on Thursday the agency staff-recommended route of the K Line Northern extension with an amendment. The amendment calls for additional study of tunneling under Mid-City to inform what that section of the train ends up looking like.
The extension: The K Line currently runs from Redondo Beach to Crenshaw and stops at the LAX/Metro Transit Center. Earlier in March, Metro officials recommended a nearly 10-mile route for the train to continue north through Mid-City and West Hollywood and terminate at the Hollywood Bowl.
No delays: Metro staff, L.A. County Supervisor Lindsey Horvath and Mayor Karen Bass assured the public Thursday that the approved amendment won’t delay the project, including the city of West Hollywood and L.A. County’s joint plan to potentially front billions of dollars to kickstart the project without raising taxes.

The Los Angeles Metro Board approved on Thursday the agency staff-recommended route of the K Line Northern extension with an amendment.
The amendment calls for additional study of tunneling under Mid-City to inform what that section of the train ends up looking like.
The amendment was billed as a compromise in a political push-and-pull that continued into early Thursday morning between unabashed supporters of the route, including the city of West Hollywood, L.A. County Supervisor Lindsey Horvath and L.A. Mayor Karen Bass, who has tried to appease persistent concerns over the project's impact on residents of the Lafayette Square neighborhood.
“ I am very optimistic, and I'm very pleased that we got to an agreement so that we can all move together jointly,” West Hollywood Mayor John Heilman said to LAist in an interview before the vote.
Metro staff, Horvath and Bass assured the public Thursday that the approved amendment won’t delay the project, including the city of West Hollywood and L.A. County’s joint plan to potentially front billions of dollars to kickstart the project without raising taxes.
“[The amendment] explicitly ensures that continued study, engagement and refinement in the Mid-City segment will proceed without scheduling, cost or job impacts,” Bass said about the amendment during the meeting.
The amendment was unanimously approved in an 11-0 vote. Metro Board Directors Jacquelyn Dupont-Walker and Holly Mitchell recused themselves since they own property in proximity to the proposed extension.

The low-down on the extension
The K Line currently runs from Redondo Beach to Crenshaw and stops at the LAX/Metro Transit Center. Earlier in March, Metro officials recommended a nearly 10-mile route for the train to continue north through Mid City and West Hollywood and terminate at the Hollywood Bowl.
The route would connect to the D Line in Wilshire and the B Line in Hollywood, closing a north-south gap that currently exists in Metro’s rail network. The extension would link to cultural hubs, including the Museum District and Hollywood Bowl, major employers such as Cedars Sinai Medical Center and queer nightlife along Santa Monica and Sunset boulevards.
According to Metro staff estimates, the route that was mostly approved today would serve the highest number of riders and reach the most residents and jobs compared to other alternatives studied.
You can read more about the specifics and the lead up to Thursday’s vote in our earlier coverage.
Didn’t Metro already study tunneling in Mid-City?
Lafayette Square residents have for years expressed fears over the effects of tunneling on property values, noise and vibration.
Based on the concerns, the Metro Board directed agency staff in October 2024 to do further analysis and community outreach. That work, which cost an additional $2.3 million, involved studying 12 different route options through Mid-City and concluded that tunneling will be deep enough to zero out any surface-level disruptions.
It’s unclear what the study prescribed by the amendment approved Thursday will materialize that hasn’t already been addressed.
Once fully built out, the K Line will run from the South Bay to Hollywood.

What happens now?
Thursday’s affirmative vote was necessary before the city of West Hollywood and L.A. County pursue a plan to capture a certain proportion of future property tax growth in a defined area near the project and funnel it towards construction. Critically, this plan wouldn’t involve raising taxes.
“Every time a property is redeveloped or sold, it adds to that increment, which adds to the amount of money that you can raise,” Eli Lipmen, head of transit advocacy group Move LA and supporter of the Metro-recommended route for the extension, said to LAist last week.
Now that the board green-lit the route, West Hollywood City Council and the L.A. County Board of Supervisors will pursue creating the district within which property tax growth could be captured.
The completion of that legislative work will trigger a 12- month clock to conduct the additional Mid-City tunneling study and finalize the route there.
It’s all about compromise
A draft version of the amendment that circulated earlier this week did not include the 12-month time cap on the additional analysis, which raised a red flag for the city of West Hollywood.
“If additional outreach and technical work must be done … it should be capped at a reasonable maximum duration to prevent further delays,” Heilman and City Councilmember Chelsea Byers wrote in a Wednesday letter to the Board.
Heilman said he worked through Wednesday night and into Thursday morning with Horvath and Metro and Bass’ staff toward the amendment that the Board approved.
Today’s vote isn’t final project approval, and it will return back to the Metro Board several more times before shovels hit the ground.
The projected cost of the train is fluid until the Mid-City section is finalized. However, earlier estimates had the staff-recommended route for the train extension coming in at around $15 billion. Measure M, the half-cent sales tax county voters approved a decade ago, includes more than $2 billion for the project.
Those funds won’t be available until the 2040s, but the financing plan that West Hollywood and the county are pursuing could expedite the release of that money and construction.
The current Metro K Line train opened to the public on October 7, 2022.

K Line Northern Extension elicited historic feedback from community
Public officials said the K Line Northern extension was an extraordinary display of community passion and pressure.
Inglewood Mayor James Butts, who sits on the Metro Board and was listed as a co-author on the draft amendment, said he received “767 emails from West Hollywood.”
“I applaud you,” Butts said during the meeting. “You guys are the strongest advocacy group I’ve seen in 54 years of municipal service.”

The International Olympic Committee will prohibit transgender athletes from participating in women's sports, starting at the 2028 Summer Olympics in Los Angeles.
The new policy, approved by the IOC's executive committee Thursday, requires all athletes to undergo a genetic test to compete in women's sporting events at the Olympics.
The move comes as transgender athletes' participation in sports at all levels — from youth athletics to professional competition — faces intense scrutiny and often partisan debate, including in communities in California.
"At the Olympic Games, even the smallest margins can be the difference between victory and defeat," IOC President Kirsty Coventry said today, announcing the ban. "So, it is absolutely clear that it would not be fair for biological males to compete in the female category."
The number of transgender women competing in international sporting events like the Olympics is estimated to be tiny, according to the Williams Institute at UCLA Law, a research center focused on sexual orientation and gender identity law and public policy. The push to bar trans athletes from girls' and women's sports has picked up as a raft of new policies in the U.S. target the rights of transgender people.
The Trump administration has ramped up efforts to keep trans athletes out of women's sports, through an executive order and legal action, including a lawsuit against California for allowing trans girls to compete in girls' school sports.
" It is basically the IOC bowing down to the pressure on its body by the federal government, and particularly Donald Trump," said Terra Russell-Slavin with the Los Angeles LGBT Center, responding to the new policy on Thursday.
About the new policy
The new Olympic policy limits participation in the women's competitions to "biological females" in order "to ensure fairness, safety and integrity in elite competition."
The IOC had previously allowed individual sports federations to set their own rules for trans athletes — but the topic became a huge focus of controversy in Paris in 2024, when conservative commentators questioned the sex of two female Olympic boxers, including gold medalist Imane Khelif, kicking off an international firestorm.
The policy change faced immediate criticism from some women's groups and LGBTQ organizations.
“By mandating sex testing and excluding transgender and intersex women from competition, the International Olympic Committee is embracing a policy that invites confusion, stigma and invasive scrutiny rather than clarity or safety," Brian Dittmeier, director of LGBTQI equality at the National Women’s Law Center, said in a statement.
Dittmeier also said the decision would "trickle down" to school sports and discourage young athletes. According to a recent survey by the L.A.-based Trevor Project, less than one in three young LGBTQ people reported participating in sports. Many cited fear of discrimination as a barrier.
The policy will require all female athletes to do an SRY gene test to determine if a "Y" chromosome is present. According to the IOC, with "rare exceptions," no athletes who test positive will be able to compete in women's sports at the Olympics.
Groups respond to new rule
InterACT, a group that advocates for intersex youth, said the IOC's new required genetic test discriminates against intersex athletes — athletes whose sex characteristics don't fall into the binary categories of male or female.
"Sex testing invades all women’s privacy, forcing them to give up their personal medical and genetic information for the IOC to determine if they are 'woman enough' to compete," Erika Lorshbough, interACT’s executive director, said in a statement.
Some groups in California celebrated the change, including the California Family Council, a conservative and religious advocacy group that is pushing the California Interscholastic Federation, California high school's governing body for sports, to ban trans youth from girls' sports.
"We're going to see that reflected in the Olympics, which will be coming up in L.A.," Sophia Lorey with California Family Council said in a video on Instagram about the IOC's new policy. "So it's going to be interesting to see how this plays out."
Russell-Slavin with the L.A. LGBT Center said Olympic organizers and local politicians should respond to the ban by affirming their support for trans people in Los Angeles.
" The fact that the policy will be implemented for the first time in Los Angeles is also at direct odds with our values as a city," she said. "I feel very clearly that one of the things that makes Los Angeles so great is our diversity and our inclusion, and this is the opposite."
