A measles outbreak is spreading across multiple states in the US, with over 250 people infected and 29 hospitalized. The Texas outbreak, which began in late January, has spread into neighboring counties and infected at least 223 people, including an unvaccinated young child who died. New Mexico has also reported cases linked to the Texas outbreak.
The low childhood vaccination rates in Gaines County, Texas, have contributed to the outbreak. Only 46% of kindergarten students had received the measles-mumps-rubella (MMR) vaccine in the 2023 school year, down from 82% in 2019. In contrast, Lea County, New Mexico, has a relatively high MMR vaccination rate for children and teens, but lower rates among adults.
Measles is highly contagious and can cause severe complications, including pneumonia, brain swelling, and death. The virus can also lead to “immune amnesia,” making the body more susceptible to future infections. Experts recommend that people get two doses of the MMR vaccine, which are 97% effective at preventing infection.
