Cellulitis, a bacterial infection of the soft tissue, is frequently encountered in both primary and secondary care settings. It can be difficult to diagnose as it shares many symptoms with pre-existing chronic diseases. It is important that nurses working in primary care can recognise the symptoms of this infection and act promptly in order to minimise distress and pain for the patient. The primary and secondary care cellulitis management algorithms presented in this paper can be used as a prompt and an aid to differential diagnosis and swift action.
