Overview

• The Health Ministry, which confirmed the case Wednesday, identified a 22-year-old unvaccinated hotel worker as the patient.
• Officials began an immediate investigation with ring vaccination at the woman’s home, workplace, and the health service she visited, plus a door-to-door sweep in her neighborhood for more cases.
• The ministry said it is coordinating the response with Rio’s state and city health departments to track contacts and speed up vaccinations.
• State health authorities reported 12 additional suspected cases under review in Rio de Janeiro.
