Health officials in Maricopa County have confirmed the sixth measles case of the year, raising concerns about potential exposure at a recent youth basketball event in Mesa.
According to the Maricopa County Department of Public Health, individuals who attended an Arizona Youth Sports basketball game on April 11 between 2 p.m. and 5 p.m. at Highland Junior High School may have been exposed to the highly contagious virus. Those present are being advised to monitor for symptoms through May 2.
Officials noted that the latest case does not appear to be connected to earlier infections reported in the county, and investigators have not yet identified the source of exposure. The uncertainty adds to growing concern as measles cases continue to surface across the region.
Earlier this month, three exposure sites were identified in Queen Creek after an infected individual visited several public locations, including retail stores and a community event, before receiving a diagnosis.
Statewide, Arizona recorded a significant number of measles cases in 2025, and early figures for 2026 suggest the trend may continue. Much of the increase has been linked to an outbreak near the Arizona-Utah border, particularly in Mohave County.
Medical experts stress that measles spreads easily, especially among unvaccinated populations. The Centers for Disease Control and Prevention warns that individuals without immunity face a high likelihood of infection if exposed.
Symptoms typically develop within one to two weeks and often begin with fever, cough, runny nose, and red, watery eyes, followed by a distinctive rash that spreads across the body. While many recover, complications can be severe, including pneumonia and inflammation of the brain.
Health officials are urging residents to ensure they are up to date on the measles, mumps, and rubella (MMR) vaccine. Anyone who begins to show symptoms is advised to stay home and contact a healthcare provider before seeking in-person care, helping to limit further spread of the virus.
