Measles Outbreak Spreads in Southwest US: Vaccination Key to Containment

New measles cases have been reported in Texas, Oklahoma, and New Mexico this week, marking the first spread of the outbreak into central Texas. Health officials warn that the virus continues to gain ground, with multiple new counties recording their first cases.

According to the Centers for Disease Control and Prevention (CDC), the U.S. has already surpassed the total number of measles cases recorded in 2024, signaling a troubling resurgence of the disease.

The Role of Vaccination in Stopping the Spread

Health experts have long cautioned that measles could establish a foothold in communities with low vaccination rates, prolonging the outbreak and increasing the risk of severe complications. The highly contagious virus spreads through coughing and sneezing, with an infected person able to transmit it to up to 90% of unvaccinated individuals in close contact.

However, the measles, mumps, and rubella (MMR) vaccine provides a highly effective defense, with two doses offering 97% protection against the disease. Widespread vaccination not only protects individuals but also helps contain outbreaks by reducing transmission, especially in vulnerable populations such as infants, pregnant women, and those with weakened immune systems.

Rising Case Numbers and Cross-Border Spread

The measles outbreak in Texas began two months ago, and as of Tuesday, state health officials reported 22 new cases since Friday, bringing the total to 422 cases across 19 counties—the majority in West Texas. Additionally, the World Health Organization (WHO) confirmed last week that measles cases in Mexico are directly linked to the Texas outbreak, highlighting the virus’s ability to cross borders if left unchecked.

Since the outbreak began, 42 individuals have been hospitalized, underscoring the seriousness of the disease.

Urgent Call for Vaccination

With cases climbing and new areas affected, health officials urge parents and communities to ensure children and adults are up to date on their MMR vaccinations. Increasing vaccination coverage is the most effective way to curb the outbreak, prevent further hospitalizations, and protect public health.
