Overview
- NHS and UKHSA materials list shortness of breath as a COVID-19 symptom that is not characteristic of uncomplicated flu or the common cold.
- Officials caution that many symptoms overlap across COVID, flu and colds, making diagnosis by symptoms alone unreliable.
- The CDC lists difficulty breathing or shortness of breath as an emergency warning sign of possible flu complications and advises seeking care right away.
- Clinicians note that severe flu that progresses to pneumonia can also cause breathing problems, so evaluation is needed if symptoms escalate.
- Coverage highlights rising winter respiratory risks as people spend more time indoors and reiterates NHS advice on vaccination where recommended.
