Acre sees highest severe respiratory illness hospitalizations in three years
The state of Acre, Brazil, has recorded its highest number of Severe Acute Respiratory Illness (SRAG) hospitalizations in three years, with 1,999 admissions between epidemiological weeks 1 and 28 of 2026. This figure surpasses the 1,732 cases in the same period of 2024 and 1,481 in 2025. The data, released by the State Secretariat of Health (Sesacre), indicates that children and the elderly remain the most vulnerable groups. Specifically, children aged 2 to 4 years accounted for the largest number of hospitalizations (411), followed by those aged 5 to 9 years (370), children under 2 years (308), and individuals 60 years and older (377).
In response to the surge in hospitalizations and increased pressure on the healthcare system, the Acre government declared a public health emergency on June 3, a measure valid for 90 days. This allows for administrative actions to expand patient care capacity. Notably, while SRAG hospitalizations have risen, consultations for general flu-like symptoms have decreased to 13,034 in 2026, down from 16,506 in 2025 and 15,211 in 2024, suggesting a shift from mild cases to more severe ones requiring hospitalization. The peak of hospitalizations this year occurred in week 22, with 103 admissions, followed by a slowdown.
The most frequent respiratory agent identified in Acre in 2026 is rhinovirus, with 184 detections, followed by Respiratory Syncytial Virus (RSV) with 64 confirmations, and various Influenza A subtypes. This year's scenario is characterized by the simultaneous circulation of multiple respiratory viruses. The Baixo Acre e Purus Health Region reported the highest concentration of SRAG cases (58.48%), with the capital city, Rio Branco, accounting for 42.8% of all state hospitalizations. The profile of deaths has also shifted, with a decrease in fatalities among those 60 and older but an increase among children under 2 years. Overall, Acre has recorded 52 SRAG deaths in 2026, compared to 101 in 2025 and 151 in 2024. Sesacre emphasizes vaccination as the primary strategy to reduce severe cases and recommends hygiene measures.
The surge in severe respiratory illness hospitalizations in Acre, particularly among young children and the elderly, highlights persistent vulnerabilities in public health infrastructure and access to preventative care. While the declaration of a public health emergency and increased focus on vaccination are critical immediate responses, the data suggests a complex interplay of factors including the simultaneous circulation of multiple viruses and potential gaps in routine immunization coverage for certain demographics. The observed decrease in mild flu consultations alongside rising severe cases warrants further investigation into the effectiveness of current public health messaging and the capacity of primary care to manage early-stage respiratory infections. Looking ahead, sustained investment in robust public health surveillance, accessible vaccination programs tailored to high-risk groups, and resilient healthcare systems capable of managing concurrent viral threats will be essential for mitigating future outbreaks and ensuring equitable health outcomes in the region.
