GAINESVILLE, Fla. — In an open- barn at the edge of the University of Florida, veterinarian Juan Campos Krauer examines a dead armadillo's footpads and ears for signs of infection.

Its claws are curled tight and covered in blood. Campos Krauer thinks it was struck in the head while crossing a nearby road.

He then runs a scalpel down its underside. He removes all the important organs: heart, liver, kidneys. Once the specimens are bottled up, they're destined for an ultra-cold freezer in his lab at the college.

Campos Krauer plans to test the armadillo for leprosy, an ancient illness also known as Hansen's disease that can lead to nerve damage and disfigurement in humans. He and other scientists are to solve a medical mystery: why Central Florida has become a hot spot for the age-old bacteria that cause it.

Leprosy remains rare in the United States. But Florida, which often reports the most cases of any state, has seen an uptick in patients. The epicenter is east of Orlando. Brevard County reported a staggering 13% of the nation's 159 leprosy cases in 2020, according to a Tampa Bay Times analysis of state and federal data.

Many questions about the phenomenon remain unanswered. But leprosy experts believe armadillos play a role in spreading the illness to people. To better understand who's at risk and to prevent infections, about 10 scientists teamed up last year to investigate. The group includes researchers from the University of Florida, Colorado State University, and Emory University in Atlanta.

“How this transmission is , we really don't know,” said Ramanuj Lahiri, chief of the laboratory research branch for the National Hansen's Disease Program, which studies the bacteria involved and cares for leprosy patients across the country.

‘Nothing Was Adding Up'

Leprosy is believed to be the oldest human infection in history. It probably has been sickening people for at least 100,000 years. The disease is highly stigmatized — in the Bible, it was described as a punishment for sin. In more modern times, patients were isolated in “colonies” around the world, in Hawaii and Louisiana.

In mild cases, the slow-growing bacteria cause a few lesions. If left untreated, they can paralyze the hands and feet.

But it's actually difficult to fall ill with leprosy, as the infection isn't very contagious. Antibiotics can cure the ailment in a year or two. They're available for free through the federal and the World Organization, which launched a campaign in the 1990s to eliminate leprosy as a public health problem.

In 2000, reported U.S. cases dropped to their lowest point in decades with 77 infections. But they later increased, averaging about 180 per year from 2011 to 2020, according to data from the National Hansen's Disease Program.

During that time, a curious trend emerged in Florida.

In the first decade of the 21st century, the state logged 67 cases. Miami-Dade County noted 20 infections — the most of any Florida county. The vast majority of its cases were acquired outside the U.S., according to a Times analysis of Florida Department of Health data.

But over the next 10 years, recorded cases in the state more than doubled to 176 as Brevard County took center stage.

The county, whose population is about a fifth the size of Miami-Dade's, logged 85 infections during that time — by far the most of any county in the state and nearly half of all Florida cases. In the previous decade, Brevard noted just five cases.

Remarkably, at least a quarter of Brevard's infections were acquired within the state, not while the individuals were abroad. India, Brazil, and Indonesia diagnose more leprosy cases than anywhere, over 135,000 infections combined in 2022 alone. People were getting sick even though they hadn't traveled to such areas or been in close contact with existing leprosy patients, said Barry Inman, a former epidemiologist at the Brevard health department who investigated the cases and retired in 2021.

“Nothing was adding up,” Inman said.

A few patients recalled touching armadillos, which are known to carry the bacteria. But most didn't, he said. Many spent a lot of time outdoors, including lawn workers and avid gardeners. The cases were usually mild.

It was difficult to nail down where people got the illness, he added. Because the bacteria grow so slowly, it can take anywhere from nine months to 20 years for symptoms to begin.

Amoeba or Insect Culprits?

Heightened awareness of leprosy could play a role in Brevard's groundswell of cases.

Doctors must report leprosy to the health department. Yet Inman said many in the county didn't know that, so he tried to educate them after noticing cases in the late 2000s.

But that's not the sole factor at play, Inman said.

“I don't think there's any doubt in my mind that something new is going on,” he said.

Other parts of Central Florida have also recorded more infections. From 2011 to 2020, Polk County logged 12 cases, tripling its numbers compared with the previous 10 years. Volusia County noted 10 cases. It reported none the prior decade.

Scientists are honing in on armadillos. They the burrowing critters may indirectly cause infections through soil contamination.

Armadillos, which are protected by hard shells, serve as good hosts for the bacteria, which don't like heat and can thrive in the animals whose body temperatures range from a cool 86-95 degrees.

Colonists probably brought the disease to the New World hundreds of years ago, and somehow armadillos became infected, said Lahiri, the National Hansen's Disease Program scientist. The nocturnal mammals can develop lesions from the illness just as humans can. More than 1 million armadillos occupy Florida, estimated Campos Krauer, an assistant professor in the University of Florida's Department of Large Animal Clinical Sciences.

How many carry leprosy is unclear. A study published in 2015 of more than 600 armadillos in Alabama, Florida, Georgia, and Mississippi found that about 16% showed evidence of infection. Public health experts believe leprosy was previously confined to armadillos west of the Mississippi River, then spread east.

Handling the critters is a known hazard. Lab research shows that single-cell amoebas, which in soil, can also carry the bacteria.

Armadillos love to dig up and eat earthworms, frustrating homeowners whose yards they damage. The animals may shed the bacteria while hunting for food, passing it to amoebas, which could later infect people.

Leprosy experts also wonder if insects help spread the disease. Blood-sucking ticks might be a culprit, lab research shows.

“Some people who are infected have little to no exposure to the armadillo,” said Norman Beatty, an assistant professor of medicine at the University of Florida. “There is likely another source of transmission in the environment.”

Campos Krauer, who's been searching Gainesville streets for armadillo roadkill, wants to gather infected animals and let them decompose in a fenced-off area, allowing the remains to soak into a tray of soil while flies lay eggs. He hopes to test the dirt and larvae to see if they pick up the bacteria.

Adding to the intrigue is a leprosy strain found only in Florida, according to scientists.

In the 2015 study, researchers discovered that seven armadillos from the Merritt Island National Wildlife Refuge, which is mostly in Brevard but crosses into Volusia, carried a previously unseen version of the pathogen.

Ten patients in the region were stricken with it, too. At the genetic level, the strain is similar to another type found in U.S. armadillos, said Charlotte Avanzi, a Colorado State University researcher who specializes in leprosy.

It's unknown if the strain causes more severe disease, Lahiri said.

Reducing Risk

The public should not panic about leprosy, nor should people race to euthanize armadillos, researchers warn.

Scientists estimate that over 95% of the global human population has a natural ability to ward off the disease. They believe months of exposure to respiratory droplets is needed for person-to-person transmission to occur.

But when infections do happen, they can be devastating.

“If we better understand it,” Campos Krauer said, “the better we can learn to live with it and reduce the risk.”

The new research may also provide insight for other Southern states. Armadillos, which don't hibernate, have been moving north, Campos Krauer said, reaching areas like Indiana and Virginia. They could go farther due to climate change.

People concerned about leprosy can take simple precautions, medical experts say. Those working in dirt should wear gloves and wash their hands afterward. Raising garden beds or surrounding them with a fence may limit the chances of soil contamination. If digging up an armadillo burrow, consider wearing a face mask, Campos Krauer said.

Don't play with or eat the animals, added John Spencer, a scientist at Colorado State University who studies leprosy transmission in Brazil. They're legal to hunt year-round in Florida without a license.

Campos Krauer's team has so far examined 16 dead armadillos found on Gainesville area roads, more than 100 miles from the state's leprosy epicenter, trying to get a preliminary idea of how many carry the bacteria.

None has tested positive yet.

Union With Labor Dispute of Its Own Threatens to Cut Off Workers’ Health Benefits

The National Education Association, the nation's largest union, is threatening to cut off health insurance to about 300 Washington, D.C.-based workers on Aug. 1 in an effort to end a bitter contract dispute.

It's a tactic some private employers have used as leverage against unionized workers that has drawn scrutiny from congressional Democrats and is prohibited for state employers in California. Experts on labor law say they've never seen a union make the move against its own workers.

“This is like a man-bites-dog situation where the union is now in a position as the employer,” said Paul Clark, a professor of labor and employment relations at Penn State University. “It's not a good look for a union.”

NEA workers with pressing health needs are worried but say they won't fold. Joye Mercer Barksdale, a writer on the NEA's government relations team, said she needs coverage for a medical procedure to address atrial fibrillation, a cardiac disorder. “This is insane for the NEA to use our health benefits as a bargaining chip,” she said.

But Barksdale said the threat isn't enough to force her to agree to an unacceptable contract. “I am not ready to give in,” she said.

The NEA Staff Organization, the union representing workers at the NEA's headquarters, launched a strike on July 5 in Philadelphia, during the union's annual delegate assembly. It was its second walkout this summer as the two parties negotiate a new contract, navigating sticking points such as wages and remote work.

In response, the NEA ended the conference early. was supposed to speak at the event but withdrew, refusing to cross the picket line. The NEA on July 24 endorsed Kamala Harris for president.

On July 8, the day after the conference had been scheduled to end, the NEA locked out workers. In a letter the day before, the NEA informed its unionized workers that they would not be paid, effective immediately, and their health benefits would expire at the end of July unless a new deal were reached.

“NEA cannot allow NEASO to act again in a way that will bring such lasting harm to our members and our organization,” Kim Anderson, the NEA's executive director, wrote in the letter, obtained by KFF Health News. “We are, and have always been, committed both to our union values and to the importance of conducting ourselves as a model employer.”

Democrats in , Sens. Sherrod Brown of Ohio and Bob Casey of Pennsylvania, introduced legislation last year to protect striking workers from losing their health benefits, after several large companies, including General Motors, John Deere, RTX (formerly Raytheon Technologies), and the maker of Kellogg's cereals, threatened to or did cut off coverage during labor disputes.

“Workers shouldn't have to choose between their 's health and a fair contract,” Brown said in a statement to KFF Health News.

The legislation was endorsed by large labor unions including the Service Employees International Union and United Steelworkers, according to a press release from Brown's office. The NEA wasn't among them.

“This tactic is immoral, and it should be illegal,” United Steelworkers' president at the time, Conway, said in the release.

Officials at the NEA, which represents teachers and other administrators, declined an interview request. In a statement, the organization's president, Becky Pringle, said “we are making every effort to reach an agreement as quickly as possible” with its staff union.

“As union who have been on strike, we recognize the significance and impact of these important decisions on a personal and family level. We truly value our employees and look forward to continued collaboration with NEASO to develop a new contract that benefits us all,” she said.

Kate Hilts, a digital strategist who works for the NEA, said she fears losing her coverage will her unable to afford treatment for a rare autoimmune disease that attacks her kidneys. Her next treatment was slated for August.

“I wake up every day and can't believe this is ,” she said. “You would expect this from an employer that is antiworker or has a terrible labor record, but I am totally flabbergasted that a labor union would do this that bills itself as pro-worker, pro-family, pro-education, and pro-children.”

The NEA staff union has filed multiple charges with the National Labor Relations Board this year, including allegations that the NEA withheld overtime pay and failed to provide information on the outsourcing of millions of dollars in bargaining unit work.

California is one of the only states that protect striking workers from losing health coverage. The state legislature passed a law in 2021 that blocks the tactic from being used against public employees and another law in 2022 that allows any striking workers who lose their insurance to immediately get heavily discounted coverage through the state's Affordable Care Act marketplace.

If they remain locked out, the NEA workers would be eligible for coverage under COBRA, a federal program that allows people who are fired or laid off to maintain their employer-sponsored insurance for 18 months.

But the coverage can be a financial hardship, as individuals often must pay the entire cost of their insurance premiums, plus a 2% administrative fee.

Another option for workers would be coverage through the Affordable Care Act marketplace, though that also could be costly. And it may be unclear how soon that coverage would begin or whether insurers would their existing doctors.

“I'm hoping the NEA will be so ashamed of what they are doing that, at the very least, they will not take away our health benefits,” Barksdale said.

The CDC’s Test for Bird Flu Works, but It Has Issues

Published

on

Arthur Allen and Amy Maxmen
Fri, 26 Jul 2024 09:00:00 +0000

The Centers for Disease Control and Prevention says a glitch in its bird flu test hasn't harmed the agency's outbreak response. But it has ignited scrutiny of its go-it-alone approach in testing for emerging pathogens.

The agency has quietly worked since April to resolve a nagging issue with the test it developed, even as the virus swept through dairy farms and chicken houses across the country and infected at least 13 farmworkers this year.

At a congressional hearing July 23, Rep. Brett Guthrie (R-Ky.) asked about the issue. “Boy, that rings of 2020,” he said, referring to when the nation was caught off guard by the pandemic, in part because of dysfunctional tests made by the CDC. Demetre Daskalakis, director of the CDC's National Center for Immunization and Respiratory Diseases, responded that the agency rapidly developed a workaround that makes its bird flu test reliable.

“The tests are 100% usable,” he later told KFF , adding that the FDA studied the tests and came to the same conclusion. The imperfect tests, which have a faulty element that sometimes requires testing a sample again, will be replaced soon. He added, “We have made sure that we're offering a high-quality product.”

Still, some researchers were unnerved by the news coming four months after the declared a worrisome bird flu outbreak among cattle. The CDC's test is the only one available for clinical use. Some researchers say its flaws, though manageable, underscore the risk of relying on a single entity for testing.

The problem came to light in April as the agency prepared to distribute its test to about 100 public health labs around the country. CDC detected the issue through a quality control system put in place after the covid test catastrophe of 2020.

Daskalakis said the CDC's original test design was fine, but a flaw emerged when a company contracted by the agency manufactured the tests in bulk. In these tests, one of two components that recognize proteins called H5 in the H5N1 bird flu virus was unreliable, eliminating an important safeguard. By targeting the same protein twice, tests have a built-in backup in case one part fails.

Advertisement

The agency developed a fix to ensure a reliable result: If only one of the two parts detected H5, the test was considered inconclusive and would be run again. With the FDA's blessing, the CDC distributed the tests — with workaround instructions — to public health labs.

Wroblewski, director of infectious diseases at the Association of Public Health Laboratories, said the results of the tests have not been ambiguous, and there is no need to discard the tests.

Still, the agency has asked a different manufacturer to remake the faulty component so that 1.2 million improved tests will be available soon, Daskalakis said. Some of the updated tests are already in stock at the CDC, but the FDA hasn't yet signed off on their use. Daskalakis declined to name the manufacturers.

Meanwhile, the outbreak has grown. Farmworkers continue to lack information about the virus and gear to protect them from it. Rural clinics may miss cases if they don't catch a person's connection to a farm and notify health officials rather than their usual diagnostic testing laboratories.

Those clinical labs remain unauthorized to test for the bird flu. Several of those labs have spent months working through analyses and red tape so that they can run the CDC's tests. As part of the licensing , the CDC alerted them to the workaround with the current test, too.

But outside select circles, the news was largely overlooked. “I'm totally surprised by this,” Alex Greninger, assistant director of the of Washington Clinical Virology Laboratory, told KFF Health News this . Greninger's lab is developing its own test and has been to obtain CDC test kits to evaluate.

“It's not a red alarm,” he said, but he's worried that as the CDC and the FDA spend months developing and evaluating an updated test, the only one available relies on a single component. If the genetic code underlying that fragment of the H5 protein mutates, the test could give false results.

It's not uncommon for academic and commercial diagnostic labs to make mistakes and catch them during quality control checks, as the CDC did. Still, this isn't the agency's first mishap. In 2016, well before the covid debacle, CDC officials for months directed public health labs to use a Zika test that failed about a third of the time.

The CDC caught and worked to remediate the situation far more quickly and effectively in this case. Nonetheless, the mishap raises concern. Michael Mina, chief science officer of the telemedicine company eMed.com, said diagnostic companies may be better suited to the task.

“It's a reminder that CDC is not a robust manufacturer of tests” and lacks the resources that industry can marshal for their production, Mina said. “We do not ask CDC to make vaccines and pharmaceuticals, and we do not ask the Pentagon to manufacture missiles.”

The CDC has licensed its updated test design to at least seven clinical diagnostic labs. Such labs are the foundation of testing in the U.S. But none have FDA clearance to use them.

Diagnostic labs are developing their own tests, too. But that has been slow-going. One reason is the lack of guaranteed sales. Another is regulatory uncertainty. Recent FDA guidance could make it harder for nongovernmental laboratories to issue new tests in the early phase of pandemics, said Susan Van Meter, president of the American Clinical Laboratory Association, in a July 1 letter to the FDA.

Advertisement

Transparency is also critical, scientists said. Benjamin Pinsky, medical director of the clinical virology laboratory at Stanford University, said as a public agency the CDC should make its protocol — its recipe for making the test — easily accessible online.

The World Health Organization does so for its bird flu tests, and with that information in hand, Pinsky's lab has developed an H5 bird flu test suited to the strain circulating this year in the U.S. The lab published its approach this month but doesn't have FDA authorization for its broad use.

The CDC's test recipe is available in a published patent, Daskalakis said.

“We have made sure that tests are out there, and that they work,” he added.

Advertisement

As the CDC came under fire at the July 23 congressional hearing, Daniel Jernigan, director of the CDC's National Center for Emerging and Zoonotic Infectious Diseases, noted that testing is just one tool. The agency needs money for another promising area — looking for the virus in wastewater. Its current program uses supplemental funds, he said: “It is not in the current budget and will go away without additional funding.”

Julie Rovner is chief Washington correspondent and host of KFF Health News' weekly health policy news podcast, “What the Health?” A noted expert on health policy issues, Julie is the author of the critically praised reference book “Health Care and Policy A to Z,” now in its third edition.

As Vice President Kamala Harris appears poised to become the Democratic Party's presidential nominee, health policy in general and reproductive health issues in particular are likely to have a higher profile. Harris has long been the Biden administration's point person on abortion rights and reproductive health and was active on other health issues while serving as California's .

Meanwhile, Congress is back for a brief session between presidential conventions, but efforts in the GOP-led House to pass the annual spending bills, due by Oct. 1, have run into the usual roadblocks over abortion-related issues.

This week's panelists are Julie Rovner of KFF Health News, Stephanie Armour of KFF Health News, Rachel Cohrs Zhang of Stat, and Alice Miranda Ollstein of Politico.

Among the takeaways from this week's episode:

  • President Joe Biden's decision to drop out of the presidential race has turned attention to his likely successor on the Democratic ticket, Vice President Kamala Harris. At this late hour in the campaign, she is expected to adopt Biden's health policies, though many anticipate she'll take a firmer stance on restoring Roe v. Wade. And while abortion rights supporters are enthusiastic about Harris' candidacy, opponents are eager to frame her views as extreme.
  • As he transitions from incumbent candidate to outgoing president, Biden is working to frame his legacy, including on health policy. The president has expressed pride that his signature domestic achievement, the Reduction Act, took on the pharmaceutical industry, including by forcing the makers of the most expensive into negotiations with Medicare. Yet, as with the Affordable Care Act's delayed implementation and results, most Americans have yet to see the IRA's potential effect on drug prices.
  • Lawmakers continue to be hung up on federal government spending, leaving appropriations work undone as they prepare to leave for summer recess. Fights over abortion are, once again, gumming up the works.
  • In abortion news, Iowa's six-week limit is to take effect next week, causing rippling problems of abortion access throughout the region. In Louisiana, which added the two drugs used in medication abortions to its list of controlled substances, doctors are having difficulty using the pills for other indications. And doctors who oppose abortion are pushing higher-risk procedures, like cesarean sections, in lieu of pregnancy termination when the mother's is in danger — as states with strict bans, like Texas and Louisiana, are reporting a rise in the use of surgeries, including hysterectomies, to end pregnancies.
  • The Government Accountability Office reports that many states incorrectly removed hundreds of thousands of eligible people from the rolls during the “unwinding” of the covid-19 public health emergency's coverage protections. The Biden administration has been reluctant to call out those states publicly in an attempt to keep the as apolitical as possible.

Also this week, Rovner interviews Anthony Wright, the new executive director of the consumer health advocacy group Families USA. Wright spent the past two decades in California, working with, among others, now-Vice President Kamala Harris on various health issues.
