Three things to remember
- Symptoms or one negative test cannot settle the diagnosis. Consider when symptoms started, the type of test and when it was taken.
- Do not delay advice if you have risk factors. The 48-hour window is not an absolute deadline that rules out flu treatment for everyone. A clinician should assess treatment choices.
- Combine household precautions. Reduce close contact and use ventilation, well-fitting masks and cough etiquette together. No single measure provides complete protection.
Prepare three notes for a consultation
- The date and time symptoms began
- Whether you are improving or getting worse, and the date of any test
- Your medical conditions and current medicines
These notes help you prepare for a conversation with a clinician. Do not use this video alone to diagnose an infection or start, stop or adjust a medicine.
