Feeling under the weather? You might have the flu! But did you know there are different types? We're breaking down the key differences between Influenza A and Influenza B to help you understand what's going on.
**Influenza A:** This is the heavy hitter, responsible for most flu pandemics. It's found in humans *and* animals like birds and pigs. Flu A viruses are also more prone to mutating, leading to new strains that can spread quickly.
**Influenza B:** While still unpleasant, Flu B is generally considered milder than Flu A. It's primarily found in humans, meaning animal reservoirs aren't a factor in its spread. Influenza B doesn't mutate as rapidly as Flu A, leading to fewer new strains.
**Symptoms?** Both Flu A and Flu B share similar symptoms like fever, cough, sore throat, muscle aches, and fatigue. Diagnosis usually requires a test.
**The Bottom Line:** Both flu types can make you miserable. Vaccination is still the best way to protect yourself from *both* Influenza A and B. Talk to your doctor if you think you have the flu and need treatment.
