Houston Pathologists Warn of Measles Outbreak Risks Amid Low Vaccination Rates

HOUSTON — During a virtual media briefing held by the College of American Pathologists, pathologists expressed significant concerns regarding Houston's vulnerability to the ongoing measles outbreak impacting West Texas. With 222 cases of measles reported across the United States in 2025, including 208 confirmed cases in Texas and New Mexico, medical experts are cautioning that even regions with high overall vaccination rates may still experience localized outbreaks due to pockets of low immunization. Dr. Ben Bradley from the University of Utah underscored the alarming fact that vaccination rates in some areas have dipped as low as 25% to 30%. This places unvaccinated individuals at an increased risk of contracting the virus, especially during social gatherings such as school events that incorporate mixed populations. The experts highlighted that a vaccination rate of 95% is essential to establish effective herd immunity against measles, which is one of the most contagious viruses known to humankind, surpassing the contagiousness of both influenza and COVID-19. Measles can infect nine out of ten unvaccinated individuals upon exposure, leading to severe complications including pneumonia and encephalitis. The outbreak's origins trace back to a Mennonite community in West Texas and have since extended to nearby states like Oklahoma and New Mexico, with additional cases surfacing as far as Pennsylvania and New York. Dr. Donald Karcher, president of the College of American Pathologists, emphasized the rarity of outbreaks since measles was declared eliminated as a community-acquired infection in the U.S. in 2000. The situation is dire, with two reported deaths linked to the outbreak, drawing parallels to the public health crisis experienced before the widespread implementation of the measles vaccine in the 1960s. Despite concerns, vaccinations remain the most effective means of protection against measles, particularly for high-risk populations such as children under five years of age. In light of the rising cases, individuals who were vaccinated before 1968 are advised to receive an updated vaccine, as the vaccine's effectiveness has improved over the years. Doctor recommendations stress that anyone who is immunocompromised, traveling to outbreak areas, or working in healthcare should consult their physician about booster shots. The resurgence of measles in the U.S. has been attributed to lower vaccination rates and international travel by unvaccinated individuals, highlighting the critical need for community outreach and trusted communication frameworks to combat vaccine hesitancy. In summary, the rising cases of measles in Houston and surrounding regions serve as a stark reminder of the importance of maintaining high vaccination rates to protect public health. The analysis of this report underscores the necessity for increased vaccination awareness and intervention efforts in susceptible communities.
