Overview
- UK clinicians say shortness of breath is uncommon with colds or flu and is more suggestive of Covid.
- A loss or change in taste or smell is reported as more likely with Covid than with other seasonal viruses.
- Onset patterns differ: flu often arrives suddenly with high fever and body aches, colds are typically milder and above the neck, and Covid frequently features a dry, continuous cough.
- If you develop symptoms and have a high temperature or feel too unwell for normal activities, the NHS advises staying home and limiting contact with others.
- Health advisers recommend keeping Covid and flu vaccinations up to date, practicing hand hygiene, considering face coverings in crowded indoor spaces, and using a test to confirm the cause.
