Ongoing measles outbreaks across several parts of the country are raising questions about whether the United States could lose its long-held status of having eliminated the virus, yet a senior CDC official said on Tuesday that such a shift would not be a major cause for alarm. According to CNN, the briefing marked federal officials’ first public comments on a continuing outbreak in South Carolina that has reached at least 646 cases, based on data from the state health department. Last year, a separate outbreak in West Texas recorded around 760 cases, making it one of the largest and deadliest measles outbreaks the U.S. has faced in decades.At the briefing, U.S. Centers for Disease Control and Prevention Principal Deputy Director Dr. Ralph Abraham, a former Louisiana surgeon general who previously scaled back some vaccine promotion efforts in his state, said there is no clear evidence proving that transmission is occurring between states involved in the outbreaks. He also stated that even if the U.S. were to lose its elimination status, it would not be a serious concern.Measles Elimination Status ‘Not Really’ A Concern, CDC Official Says“Losing elimination status does not mean measles would suddenly become widespread, nor would it change the core strategies used to control it,” Abraham said. He emphasized that vaccination remains the most effective protection against measles, while also reiterating his support for personal choice.CDC data shows the U.S. recorded 2,242 measles cases in 2025, the highest number reported since 1991. The disease was officially declared eliminated in the country in 2000. The Pan American Health Organization (PAHO) is expected to review that designation when it meets in April. When asked whether losing the status would be a significant setback, Abraham responded, “not really,” adding that the CDC’s focus is on supporting affected communities and reducing the impact of outbreaks.What Is Measles?Measles, also known as rubeola, is an extremely contagious viral illness that typically causes high fever, cough, runny nose, red and watery eyes, and a characteristic rash that begins on the face and spreads downward across the body. It spreads through respiratory droplets and can lead to severe and sometimes fatal complications, including pneumonia and inflammation of the brain known as encephalitis. Although it is preventable through the safe and effective MMR vaccine, measles remains a serious threat in many regions. There is no specific cure, and treatment focuses on managing symptoms, according to the Cleveland Clinic.Measles Cases Still Rising In The USAbout a year ago, health officials identified measles cases in a small town in western Texas. The virus soon moved into nearby counties, and other states, including Utah and South Carolina, began reporting outbreaks of their own. By the end of 2025, more than 2,200 measles cases had been confirmed nationwide, marking the highest annual total in the U.S. in 33 years, based on CDC figures.The country also recorded its first measles-related deaths in more than a decade. Two unvaccinated school-aged children in Texas died, along with an unvaccinated adult in New Mexico. It remains unclear whether the cases confirmed in Texas on January 20 are connected to outbreaks elsewhere. If they are, it would indicate that the U.S. has experienced a full year of uninterrupted measles transmission.If officials determine that measles has been spreading continuously for 12 months, the U.S. could lose the elimination status it achieved in 2000. In that case, measles would once again be classified as endemic, meaning it is consistently circulating within the country.Will US Lose Its Measles Elimination Status Soon?Last year, the CDC confirmed 2,144 measles cases across 44 states, along with nearly 50 distinct outbreaks, the highest numbers seen since 1991. Experts say the situation has been building for years, driven by declining routine childhood vaccination rates, parental exemptions, limited access to health care, and widespread misinformation. More recently, health officials under the Trump administration questioned long-established vaccine safety and cut funding for local programs aimed at boosting vaccination coverage.State health department data shows that the first known case in the Texas outbreak developed the classic measles rash on January 20, 2025. From there, the outbreak rapidly escalated. Officially, 762 people became ill, most of them in rural Gaines County, and two children died. Health officials believe the true number is higher. In March 2025 alone, 182 possible measles cases among children in Gaines County were never confirmed, suggesting the outbreak may have been undercounted by as much as 44 percent in that area.Gaps like these are common and make it harder to accurately track outbreaks. Many people in affected communities face barriers to health care and have deep mistrust of government institutions.Genetic sequencing has helped clarify some of the missing links. Ultimately, the decision may hinge on how PAHO experts interpret incomplete data, said Dr. Andrew Pavia, a Utah-based physician and longtime CDC adviser, as per CNN.“My best guess is that we will lose elimination status,” Pavia said. “The argument that this hasn’t been continuous transmission is weak, and I think they will likely err on the side of declaring a loss.”PAHO will also review Mexico’s measles-free status at the same time, Oliel said. Mexico’s largest outbreak has been linked to Texas. It began when an 8-year-old boy from Chihuahua became ill after visiting family in Seminole, Texas. Since February last year, Mexico has reported about 6,000 measles cases, with 21 deaths in Chihuahua state alone.Under PAHO’s current definition of elimination, international borders play a key role. For example, if a chain of transmission started in the U.S., spread to Mexico, and then re-entered the U.S., it would be considered a new chain. Many experts argue that this standard no longer reflects modern patterns of disease spread.What is clear, however, is that measles found widespread opportunity to spread in the U.S. in 2025. The virus moved through schools, day-care centers, churches, hospital waiting rooms, and even a detention center. New Mexico reported 100 cases and one adult death. Kansas spent seven months trying to contain an outbreak that sickened nearly 90 people across 10 counties. Ohio confirmed 40 cases, while Montana, North Dakota, and Wisconsin each reported 36.
