Overview

  • Three clade I mpox infections were confirmed this week in Los Angeles County, including Long Beach, with no recent international travel reported by the patients.
  • These are the first U.S. detections of clade I mpox without known travel exposure, and officials say they have not identified links among the cases.
  • All infected adults were hospitalized for symptoms and are now recovering at home, with no identifying details released by health departments.
  • Public health teams are conducting contact tracing, offering JYNNEOS vaccine to close contacts, and coordinating with the California Department of Public Health and the CDC.
  • Authorities describe overall risk to the public as low, noting clade I may cause more severe illness and potentially spread more easily through close, intimate contact than clade II.
