Influenza fever symptoms explained

Influenza commonly presents with a sudden combination of feverishness, aching, headache, and marked tiredness. [Chills](/symptoms/chills/) can occur before or during a temperature rise, while sweating may follow. A dry [Cough](/symptoms/cough/) and a general unwell feeling can accompany the fever. These symptoms can overlap with other infections, so symptoms alone cannot confirm the cause.

Rest and drink small amounts often. Keep track of whether you can urinate normally, remain alert, and breathe comfortably. Use fever relief only as directed and avoid taking more than one product containing the same ingredient. Keep distance from vulnerable household members while you are feverish, improve ventilation, and wash hands after coughing or blowing your nose. [Fatigue](/symptoms/fatigue/) may linger during recovery.

Contact a clinician when symptoms are becoming worse rather than gradually easing, or when fever is accompanied by persistent vomiting, dehydration, severe headache, confusion, chest pain, or difficulty breathing. Get urgent help for serious breathing difficulty, a seizure, or reduced responsiveness. Worsening cough with breathlessness may need assessment for [Pneumonia](/conditions/pneumonia/).

Ask which symptoms fit influenza, whether testing or an examination is useful, how to manage fever safely, and which warning signs should prompt urgent care.
