diabetes

Infections can occur when bacteria breach the skin surface, particularly where there is fragile skin or decreased local host defences.[20][21]

For information about history and examination of diabetic foot infections, see our topic Diabetic foot infections.

venous insufficiency

Infections can occur when bacteria breach the skin surface, particularly where there is fragile skin or decreased local host defences.[20][21]

eczema

Infections can occur when bacteria breach the skin surface, particularly where there is fragile skin or decreased local host defences.[20][21]

oedema and lymphoedema

Infections can occur when bacteria breach the skin surface, particularly when skin has been damaged previously.[20][21]

obesity

Infections can occur when bacteria breach the skin surface, particularly where there is fragile skin or decreased local host defences.[20][21]

previous episodes of cellulitis

Infections can occur when bacteria breach the skin surface, particularly when skin has been damaged previously.[20]

toe-web abnormalities

Evidence of fungal infection (tinea) may reveal the point of bacterial entry.[22] 

Fissures, scaling, and maceration may be a source of pathogen colonisation.[20]
