Mohave County says measles outbreak is over, reports first local hantavirus case and ongoing heat‑related deaths

County epidemiologist Anna presented routine infectious‑disease surveillance through June 2026 and briefed the board on several notable items. Anna said the county "tallied up an official case count of 285 cases" in the recent measles outbreak, reported more than 100 unique households affected and about 20 hospitalizations; she said 97% of case patients were not vaccinated. Anna described the outbreak as the largest in Arizona since 1991 and noted the county administered more than 1,000 MMR doses during response activities.

Anna also told the board Mohave County has its first diagnosed case of hantavirus pulmonary syndrome (a strain not linked to the cruise‑ship cluster) and that there have been no local cyclospora or infant botulism cases associated with national reports. On heat‑related mortality and morbidity, Anna said the county has about 49 currently reported heat‑related cases under review and referenced 68 identified heat‑related deaths in 2024; she acknowledged a backlog in determinations and said hospital discharge data could help the county track heat‑related illness and injuries in the future. Board members encouraged further analysis of heat injuries and local hospitalization data.
