The United States is expected to lose its measles-free status next year. If that happens, our country will once again enter an era where outbreaks are common.
More children will be hospitalized due to preventable diseases. Some people lose their hearing. Some will die. Measles is also expensive. no way new research The cost of the public health response to the outbreak, which has not yet been published in a scientific journal — with just a few cases — is estimated at about $244,000. When a patient requires hospital treatment, it costs an average of $58,600 per episode. An outbreak the same size as the one in West Texas earlier this year, with 762 cases and 99 hospitalizations, is estimated to cost about $12.6 million, according to the study.
The U.S.’s status depends on whether the country’s main outbreak this year stems from a large outbreak in West Texas that officially began Jan. 20. If these outbreaks are linked and continue through January 20th of next year, the United States will no longer be among the countries that have banished the disease.
“A lot of people have worked very hard for a very long time to achieve elimination, figuring out over the years how to make vaccines available, how to get good vaccine coverage, how to respond quickly to outbreaks to limit the spread,” said Paul Rota, a microbiologist who recently retired from the Centers for Disease Control and Prevention (CDC) after working for nearly 40 years.
Instead of acting quickly to prevent a measles resurgence, Robert F. Kennedy Jr., a lawyer who founded an anti-vaccine organization before taking the helm at the Department of Health and Human Services, undermined public health officials’ ability to prevent and contain measles outbreaks by eroding trust in vaccines. The measles vaccine is safe and effective. 4% of nearly 1,800 Confirmed cases of measles in the United States this year have been in people who have received two doses of the vaccine.
Kennedy fired experts on the CDC’s vaccine advisory committee and said, without evidence, that vaccines could cause autism, brain swelling and death. On November 19, scientific information on the CDC webpage about vaccines and autism was replaced with false claims. kennedy told the New York Times That he ordered the change.
“Do we want to go back to the pre-vaccination era when 500 children died from measles every year?” asked Demetre Daskalakis, former director of the CDC’s National Center on Immunization, who resigned last August in protest of Kennedy’s actions. He and other scientists said the Trump administration appears to be paying more attention to downplaying the resurgence of measles than to containing it.
HHS spokesman Andrew Nixon said in a statement that vaccination remains the most effective tool for measles prevention and that “CDC and state and local health agencies continue to work together to assess transmission patterns and ensure an effective public health response.”
Looking for link
CDC scientists are actually tracking measles with researchers from health departments and universities. To see if the outbreaks are linked, they are examining the genome of the measles virus, which contains all of its genetic information. Genomic analysis could help reveal the source and true scale of an outbreak, and alert officials to undetected spread.
Scientists have been performing genome analyzes of HIV, flu and COVID-19 for years, but measles is a new phenomenon because the virus hasn’t been a major problem for decades, said Samuel Scarpino, a public health expert at Northeastern University in Boston. “It is important to build a surveillance network so that it can scale quickly when needed,” he said.
“We are working with the CDC and other states to determine if what we are seeing is one large outbreak that continues to spread from state to state,” said Kelly Oakeson, a genomics researcher with the Utah Department of Health and Human Services.
At first glance, the ongoing outbreak Utah and ArizonaThe cases, which numbered 258 cases as of Dec. 1, appear to be linked to cases in Texas because they are caused by the same measles strain, D8-9171. But the variant is also spreading across Canada and Mexico, meaning the outbreak may have been sparked separately by people infected overseas. If that happens, these technologies could keep the United States from losing ground, Rota said. The absence of measles means that the virus does not continue to spread in a country all year round.
Daniel Salas, director of the Pan American Health Organization’s Comprehensive Immunization Program, said Canada lost its measles elimination status in November because authorities were unable to prove that multiple outbreaks of the D8-9171 variant were unrelated. The group, working with the World Health Organization (WHO), includes health officials from countries in North, South and Central America and the Caribbean. The group calls for the eradication of measles based on reports from scientists in the countries it represents.
Early next year, PAHO plans to hear from U.S. scientists. If the analysis shows that measles has continued to spread in the United States for a year, the organization’s director can revoke the country’s measles-free status.
“We expect countries to be transparent about the information they have,” Salas said. “We’ll ask questions like, ‘How did you determine your findings, and did you consider different angles?’”
In anticipation of PAHO’s evaluation, Oakeson and other researchers are studying how closely Utah’s D8-9171 lineage matches other lineages. Instead of looking at just short pieces of genes that indicate lineage, we are analyzing the entire genome of the measles virus, which is about 16,000 genetic letters long. Genetic mutations occur naturally over time, and as small changes accumulate, they work like a clock, allowing us to tell how much time has passed between outbreaks. “This tells us the evolutionary history of the sample,” Oakeson said.
For example, if one child directly infects another child, that child will have a matching measles virus. But the measles virus that infects people at the start of a large outbreak will be slightly different from the virus that infects people months later.
The outbreaks in Texas and Utah were caused by the same variant, but Oakeson said “the finer details lead us to believe they are not very closely related.” To find out how different they are from each other, scientists are comparing them to measles virus genomes from other states and countries.
Ideally, scientists could combine genetic research with shoe leather investigations into how each outbreak began. But many investigations end up being dry because those who were initially infected did not seek treatment or contact the health department. As in West Texas, outbreaks in Utah and Arizona are concentrated in close-knit, undervaccinated communities that are wary of government authorities and mainstream medicine.
Researchers are also trying to determine how many cases of measles go undetected. “Confirmed cases require testing, and in some communities going to the hospital to get tested costs money like a tank of gas, finding a babysitter, missing work, etc.,” said Andrew Pavia, an infectious disease physician at the University of Utah. “If your child has a measles rash but isn’t very sick, why would you bother?”
subtle surveillance
Pavia is a national Outbreak Surveillance Network CDC took the lead. Surveys are a simple way to determine the scale of an outbreak, but this becomes complicated when communities do not trust public health workers.
“In a collaborative setting, you could administer a questionnaire asking whether anyone in your household has had a rash or other measles symptoms, but the same problems that make it difficult to isolate people and get vaccinated make this difficult,” Pavia said.
Instead, Pavia and other researchers are analyzing the genome. The various variants suggest that the outbreak may be spreading for weeks or months before it is detected, infecting more people than is known.
A less invasive method of surveillance is through wastewater. This year, the CDC and state health departments began an effort to test sewage from homes and buildings for the measles virus shed by infected people. no way study in texas They found that this could act as an early warning system, alerting public health authorities to outbreaks before people reach hospital.
The quiet work of CDC scientists stands in stark contrast to their lack of public-facing activity. The CDC has not held a press briefing on measles since President Donald Trump took office, and its last publication on measles, the Morbidity and Mortality Weekly Report, was in April.
Rather than acting quickly to limit the scale of the Texas outbreak, the Trump administration hindered the CDC’s ability to communicate quickly with Texas officials and slowed the disbursement of federal emergency funding, according to an investigation by KFF Health News. Meanwhile Kennedy Broadcast mixed messages to the vaccine and did well unproven treatment.
Daskalakis said his CDC team remained silent when it asked for briefings from Kennedy and other HHS officials as the outbreak worsened in Texas.
“Objectively, they didn’t help with the Texas outbreak, so if we fail to eliminate it, they’re probably going to say, ‘Who cares?’” Daskalakis said.
Nixon, the HHS spokeswoman, said Kennedy responded strongly to the Texas outbreak by directing the CDC to provide measles vaccines and medications to the community, expediting measles testing and advising doctors and health officials. The United States remains in elimination status because there is no evidence of sustained transmission over 12 months, he added.
“Preliminary genomic analysis indicates that the Utah and Arizona cases are not directly linked to Texas,” said Jim O’Neill, acting CDC director and HHS deputy director. I posted this on social platform.
Given Kennedy’s distortions of data on vitamin A, Tylenol and autism, Daskalakis said the Trump administration might argue that it had nothing to do with the outbreak or that PAHO is wrong.
“It would be a huge stain on the Kennedy administration if Kennedy became Secretary of Health the year we lose elimination status,” he said. “I think they will do everything they can to question scientific findings, even if it means throwing the scientists under the bus.”
