Cold & flu
Colds and flu are respiratory infections caused by different viruses. They can share symptoms such as cough, sore throat, and congestion. Flu may also bring fever and body aches, and symptoms can overlap with COVID-19.

BEYOND THE DEFINITION
You don’t need the perfect words.
Understanding the basics can help you ask.
A cold commonly brings a blocked or runny nose, sneezing, throat discomfort, and cough. Several viruses can cause it. Symptoms may take time to settle, and a lingering symptom alone does not mean an antibiotic is needed or that the illness has become bacterial. [1]
Flu often arrives more abruptly and can bring marked exhaustion, body aches, fever, and a dry cough. These are useful clues rather than a home diagnosis. Severe breathing difficulty or sudden chest pain needs emergency care, whatever the presumed virus. [4]
ALSO WORTH KNOWING [1] [2] [3]
Testing and a clinician's assessment may be needed; this page cannot identify which infection someone has. [1] [2] [3]
THE CLINICAL CONVERSATION
Age, pregnancy, immune suppression, and long-term health conditions affect the urgency of a flu discussion. Tell a clinician when symptoms started and whether they are improving. Feeling very unwell, breathlessness, or failure to improve calls for medical advice rather than continued guessing. [4]
Bring the context that matters to you—your routines, your priorities, and your experience after service.

A FEW STRAIGHT ANSWERS
General information to help you prepare for a conversation about your own health.
Antibiotics target bacteria and do not treat the viruses that cause colds. A clinician may assess a different problem if symptoms suggest a complication. [1]
Combination remedies may contain the same pain reliever as another medicine you take. A pharmacist can help identify overlapping ingredients and avoid accidentally taking too much. [4]
