An adult in Maricopa County has been hospitalized due to measles, as confirmed by the Maricopa County Department of Public Health (MCDPH). The case was linked to international travel, although the patient was not contagious during their journey.
MCDPH is actively working with partner organizations to identify and inform individuals who may have been exposed. Dr. Nick Staab, Chief Medical Officer for MCDPH, emphasized, “While the overall risk to the community remains low, it’s important residents remain vigilant given the ongoing spread of measles across our state and beyond.” He noted that measles is extremely contagious but preventable through vaccination, highlighting the MMR vaccine as a critical defense.
The MMR vaccine, effective for measles, mumps, and rubella, is 97% effective after two doses and is recommended for all children. Unvaccinated adults should receive at least one dose. Generally, those born before 1957 or who had measles as children are considered immune.
Measles is transmitted through direct contact or airborne droplets when an infected person coughs or sneezes, with the virus remaining alive for up to two hours in the air or on surfaces. Transmission can occur before the onset of symptoms.
Symptoms, usually emerging 7-14 days post-exposure, include high fever (104 °F to 105.8 °F), cough, runny nose, diarrhea, red eyes, and a widespread rash following the fever. Measles can be life-threatening, especially for young children, pregnant women, and immunocompromised individuals.
Anyone exhibiting measles symptoms should self-isolate, avoid contact with others, and contact healthcare providers in advance of visits to minimize exposure risks. Healthcare providers are urged to be vigilant for cases involving fever and rash, particularly in unvaccinated patients or those with known exposure, and report any suspected cases to local health authorities.
