Influenza A & B
Rough Estimate Around **80-90%** of Flu A infections are with symptoms like fever, sore throat, cough, fatigue, and muscle aches, but will typically recover within 1-2 weeks
About 10-20% may experience complications, especially the elderly, young children, pregnant women, and those with underlying conditions like asthma, diabetes, or heart disease. These are Pneumonia, Acute Respiratory Distress Syndrome, exacerbations of asthma or COPD, rarely encephalitis, seizures, and Guillain-Barré syndrome (GBS).
The severity of Flu A infections can vary based on the **strain** of the virus (e.g., H1N1 vs. H3N2). Vaccinations, masking or social distancing can significantly influence the severity of outbreaks and the rate of complications.
We shall receive the updated Flu vaccine in early November 2025. The strains in the 2025-2026 flu vaccine are updated, with new versions of A(H1N1) and A(H3N2) viruses, and the B/Victoria lineage
