## Q&A

**Q: What is the main difference between Influenza A and Influenza B?**  
A: Influenza A is typically more common, infects both humans and animals, and can cause widespread seasonal epidemics or severe symptoms. Influenza B almost exclusively infects humans, mutates more slowly, but still causes significant fever and fatigue, especially in children and seniors.

**Q: How many days should an infected individual stay home and isolate?**  
A: Patients should isolate at home for at least 5 to 7 days from the onset of symptoms, and stay isolated until at least 24 hours after their fever resolves naturally without fever-reducing medications.

**Q: What emergency red flag symptoms require immediate medical attention?**  
A: Seek immediate emergency medical care if experiencing shortness of breath, persistent chest pain, bluish lips or face, inability to drink fluids, confusion, or a fever that returns after initial improvement.

**Q: Can dietary supplements or wellness products cure Influenza A or B?**  
A: No. Supplements do not treat or cure influenza viral infections. Prescription antivirals (like Oseltamivir) prescribed by a doctor within 48 hours of onset target the virus directly. Supplements and hydration only provide supportive nutritional maintenance for general recovery.

**Q: What are the most effective preventive measures against seasonal flu in Malaysia?**  
A: The most effective prevention is receiving an annual influenza vaccination, practicing regular hand hygiene, wearing masks in crowded indoor environments, and maintaining good indoor ventilation.
