Don’t let infections get literally under your skin

SKIN infections are extremely common and, most of the time, not serious.

But that can change quite rapidly if the infection spreads to the deeper skin layers, known as cellulitis.

Stephen Fry was struck with the infection while filming scenes as the British Prime Minister in 24: Live Another Day two years ago. He was sent to hospital with a swollen ankle, which turned out to be cellulitis.

The infection can come on suddenly and — as Fry’s tweets to fans indicated (“Being pumped & dripped with antibiotics...”) — it’s usually easily treatable.

But a speedy diagnosis and treatment is crucial, as the infection can prove deadly if not picked up early, and sometimes hospitalisation is required.

Cellulitis occurs when bacteria that normally live on the skin without causing problems get inside the skin through a break in the surface, such as an insect bite, cut or scratch.

You’re more at risk of cellulitis if you are obese, have diabetes that’s poorly managed, a weakened immune system, poor circulation or lymphoedema, which causes fluid to build up under your skin.

Cellulitis develops quickly and can affect any part of the body, but it’s most common on the lower legs, feet, hands and arms. Your skin may become hot, swollen, painful or tender and you may notice additional symptoms before or along with those above, such as feeling sick, shivering, chills or feeling unwell.

If the infection spreads to deeper tissue layers, other symptoms may include fever, rapid heartbeat, confusion or disorientation, cold, clammy, pale skin. Call 999 or go to A&E immediately.
