Acre registered an increase in cases of flu syndrome (SG) in 2025, according to Epidemiological Bulletin No. 15 released by the State Department of Health (Sesacre). Among the epidemiological weeks 1 and 20, 10,267 influenza consultations were accounted for in the three sentinel units of the state, higher than those recorded in the same period in 2023 (9,928) and 2024 (9,962).

The most affected age group has also changed. If before most cases concentrated among young people aged 20 to 29, in 2025 the larger incidence began to cover the group of 20 to 39 years. The intensification of epidemiological surveillance has contributed to the greater identification of circulating respiratory viruses, including Sars-Cov-2, Rinovirus, Respiratory Sincient Virus (VSR), Influenza A, Influenza B and adenovirus.
The situation is also worrying about Severe Acute Respiratory Syndrome (SRAG). There were 953 hospitalizations notified until the 20th Epidemiological Week of 2025. Children from 0 to 9 years old and elderly over 60 are the most vulnerable, with the highest hospitalization rates. The most detected viruses among the hospitalized were Sars-Cov-2, Influenza A and B, Rinovirus and VSR.
Despite the advance in diagnoses and notifications, the bulletin points to low influenza vaccination coverage in the state. The overall average in Acre is only 43.08%, well below the 95% target advocated by the Ministry of Health. Municipalities such as Porto Acre, Bujaria, Epitacioland and Rodrigues Alves have the worst rates.
Among priority groups, only the deprived population of liberty (70.9%) and children (53.3%) exceeded 50%mark of vaccination coverage. Already categories such as truckers (3.5%), postpartum women (2.72%) and people with permanent disabilities (1.06%) have alarmingly low rates.
The bulletin reinforces the urgent need to intensify the vaccination campaign and maintain prevention measures such as mask use, hand hygiene and social distancing, especially during the seasonal period of greater circulation of respiratory viruses. Sesacre warns that immunization remains the main tool to reduce morbidity and mortality caused by flu and other respiratory syndromes.
