The Unites States reported 122 new cases of measles last week, which has brought the national total to 1,168 in 2025. This data is released by the Centers for Disease Control and Prevention (CDC). While the outbreaks in Pennsylvania and Michigan have officially ended, others across North America continue to unfold, including in parts of Texas, New Mexico, and Canada. Resurgence of a Vaccine-preventable DiseaseMeasles is caused by a highly contagious airborne virus that spreads through coughing, sneezing, or even breathing near an infected person. It had been declared eliminated from the U.S. in 2000 thanks to widespread vaccination efforts. However, recent declines in vaccination rates and increased international travel have led to a resurgence. The disease can lead to severe complications such as pneumonia, encephalitis (brain swelling), and death, especially in unvaccinated individuals.The best defense against measles remains the MMR (measles, mumps, rubella) vaccine, typically administered in two doses during early childhood. Yet, the U.S. has seen a growing number of vaccine exemptions, which health experts say undermine community immunity.Texas UpdateTexas experienced the country’s largest outbreak this year, with 742 cases reported across 35 counties. Most were concentrated in Gaines County, where a close-knit, undervaccinated Mennonite community accounted for more than half of the state’s total cases. Two unvaccinated children — aged six and eight — died in separate incidents earlier this year.As of this week, fewer than 10 individuals in Texas are estimated to still be infectious. State health officials will now provide updates weekly instead of daily, suggesting the worst of the outbreak may be over.Active Outbreaks In Other StatesAs per CDC if a state reports three or more related cases, it would be defined as an outbreak:New Mexico has reported 81 total cases and one death. Most are in Lea County.Oklahoma has 15 confirmed and three probable cases, though locations remain undisclosed.Colorado has logged 12 cases, including a seven-case outbreak tied to a Turkish Airlines flight in May.Illinois reports eight cases in its southern region and two in Cook County.Kansas has 71 cases, mostly in Gray County.Montana, facing its first outbreak in 35 years, has 17 cases.North Dakota now has 34 cases, all among unvaccinated individuals.Ohio has reported 34 cases in two separate outbreaks.Canada and Mexico See Major Outbreaks TooCanada’s Ontario province has seen the longest outbreak in North America, with 2,009 cases and one death in a baby with congenital measles. Alberta has 761 cases. In Mexico, the state of Chihuahua reported 1,940 cases and four deaths.Symptoms and TreatmentMeasles symptoms start with high fever, cough, runny nose, and red eyes, followed by a spreading rash. Complications can be severe, especially for young children and immunocompromised individuals. There is no specific antiviral treatment; care typically focuses on symptom management and avoiding further spread.
