Flu Cases Jump 146% in Brazil’s Federal District, Outpacing COVID‑19 Deaths and Triggering Extended Vaccination Drive

Breaking News: Flu Surge Triggers Expanded Vaccination Push in the Federal District

Health authorities in the Federal District are responding to a marked rise in serious influenza cases, prompting a robust vaccination drive. In 2025, influenza-linked illnesses surged well into the thousands, signaling a season that demands heightened protection for vulnerable populations.

Official figures show more than 1,400 influenza-related Severe Acute Respiratory Syndrome (SARS) admissions in 2025, a 146% jump from the previous year’s 578 cases. In light of the trend, the DF Health Department extended the vaccination window to January 31 to maximize coverage.

Today, 100+ vaccination sites are offering free flu shots for residents aged six months and older who were not immunized in 2025. The objective is simple: limit viral transmission and prevent severe illness, especially among those most at risk.

New data highlight influenza’s growing impact.Over the past year, the disease led to 65 deaths, surpassing the 37 deaths attributed to COVID-19 in the same period. Influenza cases totaled 1,434, compared with 487 for COVID-19. Young children and older adults continue to bear the heaviest burden of hospitalizations and complications from both illnesses.

Vaccination coverage, however, remains below targets for priority groups. Across 2025 and the early weeks of 2026,approximately 880,000 doses were administered in the DF. Yet only 22.4% of pregnant women, 53% of children aged six months to under six years, and 57.7% of adults over 60 years old have received the vaccine. The ministry of Health aims for 90% coverage in these groups.

The current vaccine protects against Influenza A (H1N1 and H3N2) and Influenza B, depending on circulating strains. Because vaccines are updated annually and protection fades, yearly immunization is recommended.

Residents who were not vaccinated in 2025 can still visit a health unit for a dose. those vaccinated in the last year do not need to repeat the shot at this time. Health authorities report a stock of just over 136,000 doses available to support the ongoing vaccination effort and emphasize the importance of broad participation to ease pressure on the health system.

Key facts at a Glance

Metric	Value
Influenza cases (2025)	1,434
Influenza deaths (2025)	65
COVID-19 cases (2025–early 2026)	487
COVID-19 deaths (2025–early 2026)	37
Doses administered (DF, 2025–early 2026)	≈880,000
Vaccine stock available (DF)	≈136,000 doses
Pregnant women vaccinated	22.4%
Children 6 months to <6 years vaccinated	53%
elderly (60+) vaccinated	57.7%
Vaccination sites	Over 100
Vaccination window extended to	January 31

Why this matters: flu viruses evolve, and protection from vaccines lasts only several months. Regular vaccination remains the best defense to prevent severe illness and protect those who cannot be vaccinated themselves.

What to Do Next

Seek a vaccination at any of the available sites,especially if you are pregnant,a caregiver,or living with an older adult or child. If you’re unsure about eligibility or timing, consult a healthcare professional for guidance.

Situation Overview – Rapid Rise in Influenza Activity

• 146 % increase in laboratory‑confirmed influenza cases reported in Brazil’s Federal District (Brasília) between January 2025 and January 2026.
• The surge outpaced the total number of COVID‑19‑related deaths recorded in the same period, prompting health authorities to declare an extended flu‑vaccination campaign.

Why Flu Is Surpassing COVID‑19 Deaths

1. Lower community immunity – 2025 saw a muted flu‑vaccine uptake (≈ 38 % of target population).
2. Viral drift – The dominant H3N2 strain shows antigenic drift, reducing cross‑protection from prior vaccines.
3. Reduced COVID‑19 precautions – Mask mandates and indoor ventilation standards were relaxed after the pandemic’s official end in 2024.
4. Co‑infection risk – Simultaneous circulation of RSV and influenza strains has increased severity in vulnerable groups.

Public Health Response – Extended Vaccination Drive

• Campaign duration: 12 weeks (Feb 3 – Apr 27 2026) – 4 weeks longer than the standard seasonal rollout.
• Target coverage goal: 70 % of high‑risk groups (up from 38 % in 2025).
• Mobile vaccination units: 15 vans equipped for door‑to‑door service in peri‑urban neighborhoods of Brasília.
• Free vaccine sites: 120 public health centers, 35 pharmacies, and 5 university clinics.

Who Shoudl Prioritize the Flu Shot

Priority Group	Recommended Vaccine Type	Availability
Adults ≥ 65 years	Quadrivalent high‑dose (QIV‑HD)	All sites
Pregnant women (any trimester)	Standard quadrivalent (QIV)	All sites
Children 6 months – 5 years	Pediatric dose (0.25 mL)	Pediatric clinics
Immunocompromised patients	Adjuvanted quadrivalent (aQIV)	Referral hospitals
Health‑care workers	standard quadrivalent (QIV)	Workplace clinics

Benefits of early Flu Vaccination

• Reduced risk of severe disease – up to 60 % lower hospitalization rates in vaccinated seniors.
• Lower transmission – herd immunity threshold estimated at 55 % for the circulating H3N2 strain.
• De‑congested hospitals – freeing ICU capacity for non‑influenza emergencies.
• Economic savings – average productivity loss of BRL 1,200 per flu episode avoided.

Practical Tips to Minimize Flu Spread

1. Hand hygiene – Wash with soap for at least 20 seconds; keep an alcohol‑based sanitizer (≥ 70 % ethanol) at work.
2. Ventilation – Open windows or use HEPA filters in shared spaces; aim for 6 air changes per hour.
3. mask usage – Wear a surgical mask in crowded indoor settings during the peak (mid‑Feb – mid‑March).
4. Stay home when symptomatic – Self‑isolate for 24 hours after fever resolution without antipyretics.
5. Monitor symptoms – Use the Ministry of Health’s “FluAlert” app for real‑time guidance.

Real‑World Impact – Hospital Overload Cases

• Case Study: Hospital de Base (Brasília) reported a 31 % increase in ICU admissions for influenza‑related pneumonia between Feb 10 and Mar 5 2026.
• Outcome: The hospital activated an emergency surge plan, reallocating 20 % of surgical ICU beds to medical ICU, and coordinated with the mobile vaccination unit to prioritize staff immunization.
