Tendencias del sarampión a lo largo del tiempo
- En 2025, Texas registró el mayor número de casos confirmados de sarampión desde 1992, cuando se notificaron 990 casos en un brote. Texas reportó un total de 1,097 casos en 1992.
- Antes de 1963 en Estados Unidos se reportaban unos 500,000 casos de sarampión y 500 muertes por sarampión al año. Se producían ciclos epidémicos cada dos o tres años. Sin embargo, los expertos estiman que el número real de infecciones fue de entre 3 y 4 millones al año.
- El sarampión era común en los niños:
- Más de la mitad de los niños ya había tenido sarampión a los 6 años.
- Más de 9 de cada 10 ya lo había contraído a los 15 años.
- Tras la introducción de la vacuna contra el sarampión en 1963, los casos se redujeron en más de un 95 por ciento y los ciclos epidémicos de dos o tres años desaparecieron.
- Entre 1985 y 1988, dos tercios de los casos de sarampión en edad escolar se presentaron en niños que solo habían recibido una dosis de la vacuna.
- En 1989, los Centros para el Control y la Prevención de Enfermedades comenzaron a recomendar una segunda dosis de la vacuna triple viral (MMR) para proporcionar una mejor protección.
- Entre 2000 y 2024, la mayoría de los casos estuvieron relacionados con viajes internacionales.

Historical Measles Trends
- In 2025, Texas saw the largest number of confirmed measles cases since 1992, when 990 cases were reported in one outbreak. Texas reported a total of 1,097 cases in 1992.
- Before 1963, the U.S. had about 500,000 reported measles cases and 500 measles deaths per year. There were epidemic cycles every two to three years. However, experts estimate that the actual number of infections was 3-4 million annually.
- Measles was common in children:
- More than half of children had measles by age 6.
- More than 9 in 10 had it by age 15.
- After the measles vaccine was introduced in 1963, cases dropped by more than 95 percent, and the two-to-three-year epidemic cycles stopped.
- Between 1985 and 1988, two-thirds of school-aged measles cases were in children who had received only one dose of the vaccine.
- In 1989, the CDC began recommending a second MMR dose to provide better protection.
- From 2000 to 2024, most cases were related to international travel.
