Abstract Measles outbreaks continue to pose significant public health challenges globally despite the availability of effective vaccines. In this study, we evaluated wastewater-based surveillance for detection of measles virus during an ongoing outbreak in Texas . Weekly wastewater samples collected from two Texas cities between January 2 and March 17, 2025 were analyzed using multiple RT-PCR assays targeting the nucleoprotein and matrix genes of the measles virus. Viral RNA was detected in multiple days from both cities , with City A showing positives from January 13 and City B from January 6, both predating the first confirmed case in the state on January 23. Sequencing of PCR amplicons confirmed the specificity of detection and phylogenetic analysis using global and U.S. measles genome databases further validated that the viral RNA belonged to the currently circulating genotype D8 . Our findings demonstrate that wastewater surveillance can provide early evidence of measles virus cir...

Situation at a glance On 11 March 2025, the World Health Organization (WHO) received a report from the International Health Regulation (2005) (IHR) National Focal Point (NFP) of the United States of America (United States) on the ongoing measles outbreak in the country , notified under IHR because it is an unusual event with potential significant public health impact , with the number of cases and deaths in 2025 exceeding the numbers in previous years. Additionally, cases linked to the outbreak in the State of Texas, United States, have been reported in Mexico . Measles is a highly contagious, airborne viral disease that can lead to severe complications and death. From 1 January to 20 March 2025, 17 States have reported a total of 378 cases of measles , including two deaths - the first deaths related to measles in the United States in a decade. The majority of cases are in children who are unvaccinated or have unknown vaccination status, and the overall hospitalization rate is 17%. In ...

The Texas Department of State Health Services is reporting the first death from measles in the ongoing outbreak in the South Plains and Panhandle regions.  The school-aged child who was not vaccinated was hospitalized in Lubbock last week and tested positive for measles. As of Feb. 25, 124 cases of measles have been confirmed in the outbreak since late January. Most of the cases are in children . Eighteen people have been hospitalized over the course of the outbreak. Measles is a highly contagious respiratory illness , which can cause life-threatening illness to anyone who is not protected against the virus. During a measles outbreak, about one in five people who get sick will need hospital care and one in 20 will develop pneumonia. Rarely, measles can lead to swelling of the brain and death. It can also cause pregnancy complications, such as premature birth and babies with low birth weight. Measles can be transmitted by direct contact with infectious droplets or by airborne spread...
