In a concerning shift, measles cases in the United States have exceeded 5,000 in 2026, marking the highest annual total in 35 years, according to the latest data from the Centers for Disease Control and Prevention (CDC). This alarming increase is seen as a significant public health issue, particularly as the nation grapples with a resurgence of a disease that had previously been declared eliminated in the country as of the year 2000.

As of November 6, 2026, the CDC has confirmed 5,182 cases of measles across the country. This number represents the highest incidence of the disease since 1991, when over 9,600 cases were recorded. The CDC indicates that this year’s figure demonstrates a sharp rise from 2025, where the number of confirmed infections stood at 2,289, and a dramatic increase from just 285 cases in 2024.
The rising trend has been equally reflected in the health impacts of the virus, with at least 562 individuals hospitalised due to measles this year. This accounts for approximately 11% of all reported cases. Furthermore, while the CDC has confirmed four measles-related deaths, state-level data suggests that the actual number may be as high as eight, indicating a troubling fatality rate associated with this outbreak.
Children and adolescents appear to account for a significant proportion of the infections. The CDC’s statistics reveal that among the confirmed cases, 908 involve children under the age of five, while 2,104 cases affect individuals between five and 19 years old. Alarmingly, 96% of those infected were either unvaccinated or had an uncertain vaccination history, highlighting the critical role that vaccination rates play in disease control.
In a particularly tragic update, the New York State Department of Health recently noted its first measles-related death in three decades, involving a child from Lewis County. The age of the child has not been disclosed. Similarly, the Wisconsin Department of Health reported the death of an infant linked to the ongoing measles outbreak in the southwestern part of the state, which marks the first such fatality in Wisconsin since 1990.
This resurgence of measles has been linked to a decline in vaccination rates nationwide. The CDC has identified a disturbing trend; the MMR (measles, mumps, and rubella) vaccination rate among kindergarten children dropped from 95.2% during the 2019-2020 school year to 92.4% in the 2025-2026 period. This decline equates to roughly 280,000 kindergarten-age children who are considered “at risk” for contracting measles and furthering its spread.
Measles is an exceptionally contagious viral illness that is transmitted through the air when an infected person coughs or sneezes. Initial symptoms typically include fever, cough, a runny nose, and red, watery eyes, followed by a rash that often begins on the face before spreading downwards. Individuals who have measles can be contagious from four days prior to the appearance of the rash to four days afterward, which poses a challenge in controlling outbreaks.
While many individuals recover from measles, it is important to note that the disease can lead to severe complications, including pneumonia, encephalitis (inflammation of the brain), and, in some cases, death. These risks underscore the importance of maintaining high levels of vaccination coverage to prevent outbreaks of such a highly infectious disease.
The recent influx of measles cases not only highlights the urgent need for improved vaccination strategies but also reflects broader issues regarding public health messaging and vaccine hesitancy. As health officials continue to monitor the situation, it is critical for communities to reinforce the importance of immunisation as a protective measure against measles and other preventable diseases.
With a focus on restoring public trust in vaccines, health authorities are urged to ramp up campaigns aimed at informing and educating the public about the risks associated with measles and the safety of the MMR vaccine. This proactive approach may be integral in curbing the current outbreak and preventing future occurrences while safeguarding the health of vulnerable populations, particularly children.
