Experts Warn Other Diseases Could Follow [Watch (HLS stream): Measles Cases Are at a 33-Year High. Experts Warn Other Diseases Could Follow](https://cdn.jwplayer.com/manifests/JEZPsDUn.m3u8) (2:28)  _Published 2025-07-10. The U.S. is having its worst year for measles spread in more than three decades, with a total of 1,288 cases nationally and another six months to go in 2025._ Description, summary, key points, chapters, key quotes, questions and transcript, where present, were produced automatically from the video or its captions and were not reviewed. ## Summary An expert explains how measles went from a common disease to one declared eliminated in the United States by 2000, and why that status is now at risk. The speaker describes the rule for losing elimination and notes that the current outbreak is about halfway to that threshold. The video also covers the speaker's concerns about a degraded public health system, reduced federal funding and capacity, and misinformation. It closes with the speaker's reflections on discarded public health tools. ## Key points - Measles is a highly contagious respiratory virus; effective vaccines arrived in 1964 and cases declined worldwide and in the United States. (00:00) - By the year 2000 the U.S. declared measles eliminated, meaning cases will not keep propagating through the population, and it continues to be eliminated. (00:22) - A large 2019 outbreak in New York exceeded 1200 cases and came very close to causing the U.S. to lose elimination status. (00:43) - Elimination is lost if there is a continuous chain of transmission extending past a year or 52 weeks. (00:58) - The current outbreak is about halfway to the one-year threshold, dating from around January 20th to the present day. (01:07) - The speaker questions whether the outbreak can be contained or is already out of the bottle. (01:16) - The speaker says the U.S. public health system has degraded over five years, through Covid and recent federal decisions to reduce funding and capacity. (01:24) - The speaker cites distrust of evidence-based science, conspiracy concerns and people who profiteer off misinformation as making the response more difficult. (01:42) ## Chapters - [00:00 to 00:34] Vaccines and measles elimination in the U.S.. The speaker describes measles, the 1964 vaccines, and the declaration of elimination by 2000. - [00:34 to 01:16] Outbreaks and the risk of losing elimination. The speaker discusses the 2019 New York outbreak, the 52-week rule, and the current outbreak's halfway point. - [01:16 to 01:42] Concerns over a degraded public health system. The speaker raises the question of containment and cites degraded public health capacity and federal funding cuts. - [01:42 to 02:28] Misinformation and discarded health tools. The speaker discusses distrust of science, misinformation profiteering, and the sadness of seeing helpful tools discarded. ## Key quotes - [00:22] Expert: "to the point that by the year 2000 we declared measles eliminated," - [00:58] Expert: "The rule is that you have to have a continuous chain of" - [01:16] Expert: "The question is, do we contain this or is it kind of already out of the the bottle here?" - [01:24] Expert: "My fear right now is over the last five years," - [02:19] Expert: "helpful and see that they're discarded for no good reason," ## Questions this video answers - When was measles declared eliminated in the United States and what does elimination mean? [00:22] - How close did the 2019 New York outbreak come to ending U.S. measles elimination? [00:43] - What rule determines whether the U.S. loses measles elimination status? [00:58] - How far along is the current outbreak toward the one-year threshold? [01:07] - Why does the speaker fear the public health system cannot contain the current outbreak? [01:24] ## Content suitability - health controversy [01:24-02:28]: Speaker criticizes federal funding and capacity reductions, public distrust of evidence-based science, conspiracy concerns, and people profiteering off misinformation. by [Chantelle Lee](https://time.com/author/chantelle-lee/) ## Chantelle Lee Reporter Updated: Jul 10, 2025 5:46 PM UTCPublished: Jul 9, 2025 11:28 PM UTC The U.S. is having its worst year for measles spread in more than three decades, with a total of 1,288 cases nationally and another six months to go in 2025. by [Chantelle Lee](https://time.com/author/chantelle-lee/) ## Chantelle Lee Reporter Updated: Jul 10, 2025 5:46 PM UTCPublished: Jul 9, 2025 11:28 PM UTC The number of [measles cases](https://time.com/6835635/measles-outbreak-2024/) in the U.S. has reached a 33-year record high, years after it was officially eliminated in the country, prompting public health experts to sound the alarm that other diseases could experience a similar resurgence. There have been 1,288 confirmed measles cases in the U.S. this year as of Tuesday, according to the latest [data](https://www.cdc.gov/measles/data-research/index.html) released by the U.S. Centers for Disease Control and Prevention (CDC). That’s the largest number of cases reported in the country since [1992](https://archive.ph/Jn07H)—eight years before the disease was declared eliminated from the U.S. Measles is a highly contagious disease that can lead to serious health complications, including death, but is vaccine preventable through the [measles, mumps, and rubella (MMR) vaccine](https://time.com/7261250/measles-vaccine-what-to-know/). Public health experts have largely credited its official elimination from the U.S. to a successful vaccination program. Over the past few years, however, vaccination rates have [decreased](https://time.com/7290450/measles-vaccination-rates-declining-study/), and the number of measles cases has soared. In 92% of the cases confirmed in the country so far this year, CDC data show, the person who got measles was unvaccinated or their vaccination status was unknown. **Read More:** [_Do You Need a Measles Vaccine Booster?_](https://time.com/7278878/do-you-need-a-measles-vaccine-booster/) The alarming new case milestone didn’t come as a surprise to many public health experts. “I was expecting us to hit this record this year,” says [Katelyn Jetelina](https://time.com/6968394/katelyn-jetelina/), an epidemiologist and founder of the newsletter [Your Local Epidemiologist](https://yourlocalepidemiologist.substack.com/). “But it was more of the reality hitting that this has finally happened—that we are really here in this moment in 2025\. And I’m very concerned about what it means for the future.” Experts warn that the rise in measles cases could be a harbinger for an increase in the prevalence of other diseases too. “Measles is the [most contagious virus](https://www.nfid.org/resource/frequently-asked-questions-about-measles/) on Earth, so it’s often the first to resurge when vaccination coverage declines,” Jetelina says. “We’ve managed to keep measles at bay for decades thanks to high vaccination rates, but those rates are slipping.”  Experts have pointed to a variety of reasons for falling vaccination rates, including an [increase in vaccine hesitancy](https://www.unicef.org/rosa/press-releases/new-data-indicates-declining-confidence-childhood-vaccines-44-percentage-points-some) amid the COVID-19 pandemic and as vaccine skeptics like [Health and Human Services Secretary Robert F. Kennedy Jr.](https://time.com/7222309/rfk-jr-confirmed-hhs-public-health-react/) have gained prominence. Kennedy, who has long spread disinformation about vaccines, last month [removed](https://time.com/7292553/rfk-jr-removes-cdc-vaccine-committee-experts/) all 17 members from a CDC vaccine advisory committee and appointed in their place several members who have previously expressed [vaccine skeptic views](https://www.npr.org/sections/shots-health-news/2025/06/25/nx-s1-5438482/cdc-vaccine-committee-acip-meeting-rfk). The new committee [met](https://www.politico.com/news/2025/06/26/kennedys-vaccine-panel-met-for-the-first-time-heres-what-to-know-00428461) for the first time weeks later, voting to stop recommending flu shots that contain thimerosal, an additive that the anti-vaccine movement has attacked for years despite numerous scientific studies finding [no evidence](https://www.cdc.gov/vaccine-safety/about/thimerosal.html) that the trace amounts contained in some vaccines are harmful. The committee also indicated that it will review some childhood immunizations, leaving the door open for possible changes in the schedule of childhood vaccinations. The Department of Health and Human Services (HHS) said in a statement that it “continues to support community efforts in dealing with the measles outbreaks.” “Measles risk is higher in U.S. communities with low vaccination rates in areas with active measles outbreaks or with close social and/or geographic linkages to areas with active measles outbreaks,” HHS said in the statement. The agency said that the “CDC continues to recommend MMR vaccines as the best way to protect against measles,” but then added that “the decision to vaccinate is a personal one. People should consult with their healthcare provider to understand their options to get inoculated and should be informed about the potential risks and benefits associated with vaccines.” The threshold for herd immunity against measles is [generally considered](https://www.who.int/news-room/questions-and-answers/item/herd-immunity-lockdowns-and-covid-19#:~:text=The%20percentage%20of%20people%20who,among%20those%20who%20are%20vaccinated.) to be 95%, meaning that 95% of people need to be vaccinated against the disease to prevent it from spreading. Data indicate that the U.S. has now dipped below that threshold: In the 2023-2024 school year, vaccination coverage among kindergartners was just 92.7%, according to the [CDC](https://www.cdc.gov/measles/data-research/index.html). If this trend continues for other immunizations, experts say, it’s possible other diseases could resurge. Which diseases those could be, though, “depends on how bad this is going to get,” Jetelina says. Many diseases have a lower herd immunity threshold than measles—polio’s, for instance, is [around 80%](https://www.who.int/news-room/questions-and-answers/item/herd-immunity-lockdowns-and-covid-19)—so “it’s going to take a lot more” for vaccination rates to drop that drastically, she adds. Michael Osterholm, the director of the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota, says he fears that the U.S. could face increasing cases of mumps and rubella, since the MMR vaccine protects against those diseases, too. The U.S. has already experienced a [rise in whooping cough cases](https://time.com/7278125/whooping-cough-what-to-know/), due in part to declining vaccination rates, as well as the [introduction](https://www.kqed.org/stateofhealth/145269/whooping-cough-booster-protection-fades-quickly-kaiser-study-shows) of a new type of vaccine for the disease in the 1990s to replace one that was more effective but also had more side effects. “I think right now, all vaccine preventable diseases are, in one way or another, at risk of experiencing major increases in illness,” Osterholm says. “I think you’re going to begin to see over time more of these vaccine preventable diseases coming back, and we're going to start seeing kids seriously ill and dying.” Public health experts describe feeling like America has suffered from a kind of amnesia over how serious many of these diseases are and why officials have encouraged getting vaccinated against them. Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, says he wishes that more people understood how dangerous measles can be. “Those two little girls—that six-year-old and eight-year-old that died in west Texas—were perfectly healthy children,” Offit says. “The reason they died is because measles can kill anybody, and I think we live in this sort of state of blissful ignorance, and you never think it’s going to happen to you until it happens to you.” Thirteen percent of the confirmed measles cases in the U.S. this year have resulted in hospitalization, according to the CDC, including 21% of cases in children five or younger. Three people are confirmed to have died. At the same time, experts stress that this issue goes beyond measles. “I want people to realize that this is not just about measles,” Jetelina says. “It’s far more than an infectious disease flare-up; it’s a symbol of broken trust, eroded progress, rise of individualism replacing collective good, this system that’s cracking under the weight of disinvestment and distrust.” “Measles is a canary in the coal mine, and it signals something that has gone seriously wrong,” she continues. “It’s an unraveling of decades of progress, and there’s a lot that needs to be done so we don’t keep going backwards.” ## Transcript [00:00] Measles is a highly contagious respiratory virus that has plagued humans for an eternity. [00:08] But with the advent in 1964 of very effective vaccines, [00:15] we saw a decline across the world and in particular in the United States, [00:22] to the point that by the year 2000 we declared measles eliminated, [00:28] which means cases will not keep propagating through the population. [00:34] It continues to be eliminated. [00:36] But that doesn't mean that we don't have big outbreaks and cases that keep going. [00:43] For example, in 2019, [00:46] we had a large outbreak in New York that, [00:50] uh, was over 1200 cases. [00:54] And we came very close with that outbreak to losing elimination. [00:58] The rule is that you have to have a continuous chain of [01:01] transmission that extends past a year or 52 weeks. [01:07] And so right now we're about halfway there. [01:10] Uh, from January, uh, [01:13] 20th or thereabouts until present day. [01:16] The question is, do we contain this or is it kind of already out of the the bottle here? [01:24] My fear right now is over the last five years, [01:27] we've seen the public health system in this country really degraded. [01:30] Um, you know, throughout Covid, [01:33] uh, and more recently, uh, [01:36] through some decisions being made federally, uh, [01:39] to reduce funding and capacity. [01:42] It really is made more difficult when you don't have an intact public health system, [01:49] when you don't have a population that believes in [01:55] evidence based science and is wracked with concerns about conspiracy. [02:01] And you have people who basically profiteer off misinformation, [02:08] all of us are kind of they're pulling for our patients. [02:11] We're for our communities, for our populations. [02:15] And when we have tools that can really be [02:19] helpful and see that they're discarded for no good reason, [02:24] it it's met with a little bit of melancholy on our part. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/7301457/measles-cases-record-vaccine/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/7301457/measles-cases-record-vaccine/"},"headline":"Measles Cases Are at a 33-Year High.
