Swine Flu Symptoms: Fever Not Always Present

Swine flu (H1N1) can occur without fever. While fever is common, its absence does not rule out infection.

Common Symptoms

• Cough, sore throat
• Runny/stuffy nose
• Body aches, chills
• Fatigue
• Vomiting, diarrhea (more common than seasonal flu)

Diagnosis and Treatment

• Rapid influenza test or PCR.
• Antivirals (oseltamivir) if started ≤48h of onset, especially for high-risk groups.
• Supportive care: hydration, rest, fever/pain control.

Seek medical evaluation if symptoms are severe or you have underlying conditions (asthma, diabetes, pregnancy, immunocompromise).
