(NEW YORK) — Measles cases in the United States have surpassed 2,000 for the second year in a row, according to data updated Friday from the Centers for Disease Control and Prevention (CDC).

So far in 2026, 2,030 confirmed cases have been recorded in 38 states and the District of Columbia, CDC data shows.

Cases have been confirmed in: Alaska, Arizona, California, Colorado, Florida, Georgia, Idaho, Illinois, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Texas, Utah, Vermont, Virginia, Washington, Wisconsin and Wyoming.

Just 10 measles cases were reported among international travelers so far this year, according to CDC data.

Last year, 2,288 confirmed measles cases were reported for all of 2025. Prior to this, measles cases had not surpassed 2,000 in the U.S. since 1992.

The U.S. also saw its first measles deaths in more than a decade last year, including two among unvaccinated school-aged children in Texas and one among an unvaccinated adult in New Mexico.

The majority of measles cases in 2026 have been confirmed among children and teenagers aged 19 and younger, according to the CDC.

About 92% of cases are among people who are unvaccinated or whose vaccination status is unknown, CDC data shows.

Meanwhile, 4% of cases are among those who have received just one dose of the measles, mumps, rubella (MMR) vaccine and 4% of cases are among those who received the recommended two doses, according to the CDC.

Dr. William Schaffner, a professor of preventive medicine at Vanderbilt University Medical Center in Nashville, referred to the latest figures as “very disappointing and very concerning.”

“It indicates that an increasing number of parents are either postponing or withholding their children from vaccination, and this is very concerning because it permits this virus back now into in the United States to continue to spread and obviously to cause illness in the children affected,” he told ABC News.

January 2026 marked one year since measles cases were first detected on Texas. It’s unclear if the cases confirmed on Jan. 20, 2025, are linked to those that have been found other states; if so, it would mean the U.S. has seen a year of continuous transmission.

If it’s determined that the U.S. has experienced 12 months of continuous measles transmission, it could lead to a loss of the country’s elimination status that was earned in 2000. Measles would once again be considered endemic or constantly circulating.

The review of the measles elimination status in the U.S., which is determined by the Pan-American Health Organization, will take place in November 2026.

Schaffner said the U.S.’s measles elimination status is threatened as a result of so many cases.

“Measles, because it’s the most contagious virus, is like the canary in the coal mine; it’s the alert that lets us know that we’re also opening ourselves up to other transmissible diseases that vaccines could prevent,” he said.

The CDC currently recommends that people receive two doses of the MMR vaccine, the first at ages 12 to 15 months and the second between 4 and 6 years old. One dose is 93% effective, and two doses are 97% effective against measles, the CDC says.

However, CDC data show vaccination rates have been lagging in recent years. During the 2024 to 2025 school year, 92.5% of kindergartners received the MMR vaccine, according to data. This is lower than the 92.7% seen the previous school year and the 95.2% seen in the 2019 to 2020 school year, prior to the COVID-19 pandemic.

Schaffner said that public health specialists need to listen carefully to parents who are skeptical or hesitant of getting their children vaccinated.

“Have them speak to their own family doctors and pediatricians, have those conversations, and our pediatricians and family doctors have to provide a level of comfort and reassurance,” he said. “Facts are fundamental, but more importantly, these parents need reassurance and a level of comfort that what their doctors … are recommending is in the best interest of their child and the communities in which their children live.”

“These diseases are bad and can be really bad. The vaccines are good and really good,” Schaffner added.

What we learned this week at Lindsay Clancy’s trial

By CNN
(CNN) — Lindsay Clancy has not taken the stand, but the Massachusetts mother accused of killing her three children communicated in multiple ways at her murder trial this week.She vocally answered the judge’s questions about a legal issue, her first audible words in the trial. She sobbed and shook during difficult testimony about the autopsy of her infant son. And her diary entries about her parenting stresses and postpartum issues were read aloud in court.Together, Clancy’s vocal, physical and written messages offered key insights into her perspective in the second week of her trial on three counts of murder in the killings of her children Cora, 5; Dawson, 3; and Callan, 8 months.This week’s proceedings in a Plymouth, Massachusetts, courtroom also featured testimony about her mental health status before and after the killings, her physical injuries from her suicide attempt, and her friends’ and family’s concerns.Prosecutors argue Clancy, 35, “acted intentionally, rationally and swiftly” when she fatally strangled her three children at their Duxbury home on January 24, 2023. Her defense attorneys argue she is not criminally responsible because she was in the midst of a psychotic episode stemming from postpartum mental illness.Testimony began two weeks ago with opening statements and an emotional witness account from her husband, Patrick Clancy.Here’s what we learned at Lindsay Clancy’s trial this week:Defendant speaks, sobs and writesWith the jury outside of the room, Clancy answered several questions from the judge Tuesday about her understanding of a stipulation agreement, which is an acknowledgement of specific facts to save time in a trial. Judge William F. Sullivan repeatedly asked her if she understood her rights, and she responded with an even voice: “Yes, your honor.”The topic was not particularly notable – basically agreeing the chain of custody of some evidence was proper – but it was the first time the public has heard her voice in this trial.The jury saw her get emotional, too. On Thursday, Clancy loudly sobbed, shuddered and covered her face with her hands as a medical examiner testified about Callan’s autopsy.Prosecutors displayed multiple pictures of Callan at the time of his autopsy to the parties and jury, though they were not shown on camera. The baby’s injuries were consistent with a ligature strangulation, and his cause of death was complications of mechanical asphyxia, the examiner testified.Further, the jury heard her written messages in her diary. On Monday, attorneys read aloud some of her diary entries about her declining mental health while trying to care for her three children.“It’s like I’m so desperate to get a mental break from taking care of everyone that my mind is trying to make something physically wrong with me,” she wrote.She wrote she felt “guilty” and was struggling to sleep-train Callan.“I want help. I want to be well,” she wrote.Her mental health before the killingsOn Friday, the court heard testimony from two psychiatrists who treated Clancy in the weeks and months before she killed her children.Dr. Jennifer Tufts, a licensed psychiatrist, described her interactions with the defendant over roughly a dozen sessions from September 2022 to January 2023, and repeated adjustments to Clancy’s medication as she grappled with anxiety and trouble sleeping.At their first session, Clancy told the psychiatrist she didn’t have any suicidal intent, homicidal intent or hallucinations, Tufts said. The psychiatrist’s records from the appointment indicated Clancy said she was feeling overwhelmed, her children were challenging and she felt anxious leaving her baby.The doctor met with Clancy on October 3, 2022, after Clancy asked her to facilitate an extension for her maternity leave, citing “postpartum anxiety/depression.”Clancy worked as a labor-and-delivery nurse.“I don’t feel mentally well enough to return to taking care of patients with a baby at home that still won’t take the bottle,” Clancy wrote in a message to Tufts before the appointment, per the prosecution. “I know this will trigger my anxiety too much.”By the start of December 2022, Clancy was seeing another medical provider in addition to Tufts and had tried “a few different medication combinations,” the psychiatrist testified. According to prosecutors, Tufts’ notes included a quote from Clancy, which said: “I think it’s my problem. I keep reaching out to different people and not sticking with the plan.”At that time, Clancy reported having intrusive thoughts which she described as “a feeling like I’m going to die.” Still, she denied having thoughts of self-harm, according to Tufts.By mid-December, Clancy was feeling very depressed, Tufts said. She had recently gone to the emergency room due to suicidal ideation and was planning on attending a partial hospitalization program, as well as starting a new medication, she said.In early January 2023, weeks before the killings, Clancy underwent a multiday stay at a psychiatric facility, where she was treated by another psychiatrist, Dr. Alia Goodheart, who also testified Friday.Clancy then said she felt “numbness” and appeared anxious, but she displayed linear thinking and was goal-directed, Goodheart said. The psychiatrist diagnosed her with insomnia and worked to adjust her medication.After several nights of sleep, Clancy asked to be discharged from the facility a day early “so she could be home with her family and her children,” Goodheart said.“She was future-oriented, she was clearly invested in her children, she was a caring mother,” the psychiatrist said.Days after her discharge from the in-patient facility, Clancy still felt “numb” and “flat,” Tufts testified.“She wasn’t able to cry, but she said she was able to laugh a little bit and hadn’t been having recent thoughts of suicidal ideation,” the psychiatrist said, adding she again adjusted Clancy’s prescriptions.In an email to Tufts on January 11, 2023, Clancy asked the psychiatrist’s opinion on ketamine therapy. “This has been going on for months now and I’m getting desperate for something that would work quickly to get me out of this depressed state,” Clancy wrote in part, according to prosecutors.Clancy was still depressed on January 16, the psychiatrist said, and they agreed on a plan to taper her off one medication and start taking a new antidepressant.“She was doing what she needed to do to take care of her baby, though she subjectively felt like the bonding was forced with the baby,” Tufts testified.Clancy met with Tufts the day before she killed her children.“She said she was doing all right – a little more anxious, and the anxiety was described as the feeling of her heart racing,” the psychiatrist said.Clancy said at that time she was not having any suicidal or homicidal ideation, Dr. Tufts said. Nothing Clancy said indicated she was a danger to anyone, the psychiatrist testified, and she never showed any signs of psychosis during any of their sessions.Testimony is expected to resume Monday with the defense’s cross-examination of Tufts.Her mental health afterwardTwo forensic psychiatrists testified Monday that Clancy appeared clear-headed and rational in the days after the killings.In a hospital evaluation two days afterward, Clancy could not speak because she was on a ventilator, so she asked for a paper and pen to write her responses to questions.She wrote that she was “horrified” and asked for an attorney, Dr. Jhilam Biswas testified. She also wrote, “is my body broken,” “are my legs straight,” if she could have visitors and where her family was, according to Biswas. Clancy seemed anxious, but she understood the questions and did not show signs of psychosis or hallucinations, Biswas said.Another psychiatrist, Dr. Sejal Shah, said Clancy was “calm and cooperative” during a psych exam one week after the killings. Clancy’s thought-process was “organized” and “goal-directed,” Shah said, and she agreed Clancy was an “honest” patient.Clancy had ‘dark thoughts’Clancy’s friends and family members spoke about her behavior in the weeks before the killings.In January 2023, days before she killed her children, Clancy said over text that a medication caused her to have “some dark thoughts,” her friend of nearly 30 years testified.“She had shared that she had been taking a medication that caused her to have some dark thoughts but that she was going to, or had been, tapering off that medication and was trialing new ones that would remove those side effects and be more helpful and therapeutic to what she needed,” Amy Bevins said.The tone of the conversation was “hopeful,” Bevins said, adding it seemed Clancy thought things were “moving in a positive direction.”Her father-in-law, Christopher Clancy, said she seemed “very good” during a visit in mid-November 2022 but was “quiet” during Thanksgiving. At times she seemed blank, he testified, saying she sometimes had “a stare – just not totally interacting, almost like nervous.”He saw Clancy and the family again shortly before Christmas 2022, he said, and was aware she was having “struggles” at the time.“I knew she was having a hard time sleeping. I knew she just didn’t feel well. I knew she had gone to the emergency room where my wife was working,” he testified during cross-examination.Elaine Rossi, a part-time nanny for the Clancy family, said Lindsay Clancy told her about having postpartum issues. Rossi said she saw prescription bottles in the house but she had no concerns about Lindsay with the children, calling her a “wonderful mom.”Clancy brought her daughter, Cora, to the pediatrician just hours before the killings, and nothing seemed amiss, the pediatrician testified.“I didn’t notice anything out of the norm,” Dr. Lindsay Rosshirt said. “(Cora) seemed perfectly well-behaved, and mom seemed appropriate as well.”She said she did not remember any visible signs of postpartum issues in Clancy during their appointments and did not see a need to refer her to any resources.Her physical injuriesTestimony early in the week focused on the extent of Clancy’s physical injuries and medical recovery after her suicide attempt.Prosecutors say after killing her children, Clancy cut her wrists and neck and jumped from a second-story window, leaving her partially paralyzed. She was first taken to South Shore Hospital and then transferred to Brigham and Women’s Hospital in Boston for treatment.Clancy had a thoracic spine injury from her fall, but the cuts on her neck and wrists were considered “superficial,” said Dr. Kelly McDonough, a physician at South Shore Hospital. The cuts on her wrists required several sutures, physician associate Eitan Negri said.Once she was moved to Boston, Clancy went into cardiac arrest and had to be revived with CPR and chest compressions, ICU nurse Rachelle Amedee said. Clancy also received multiple blood transfusions, she said.Superficial or not, those cuts were bloody, and prosecutors showed the jury the blood stains found in the family’s Duxbury home. A blood stain analyst testified about the drip stains, smear stains and transfer stains on the floor, mirror, nightstand and windowsill.The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
