In an official statement on Tuesday, January 17, the Acre State Health Department (Sesacre) confirmed the first case of mpox for the state, detected in Brasiléia, a municipality in the interior region. The disease was confirmed through laboratory testing, and health authorities are actively monitoring the patient's condition. This case is noted to be imported, indicating that the infection was not contracted within the state of Acre itself, but rather during travel to São Paulo.

The patient, who experienced symptoms about a week after returning to Acre, traveled to São Paulo where the possibility of exposure to the virus may have occurred. This timeline suggests a careful observation of travel history is vital for understanding the spread of mpox in Brazil. The involvement of the strategic information center for health vigilance, both at the national level and local level in Brasiléia, highlights an organized response to the emerging public health situation.

Additionally, health authorities in the Bolivian city of Cobija and São Paulo have been notified to initiate contact tracing protocols. Such cross-border cooperation illustrates the importance of regional collaboration in managing infectious diseases, especially in areas like Acre that are near international borders. The implications of this case could enhance public health policies and responses tailored to similar situations in the future.
