The number of scarlet fever cases in Cumbria this winter has now reached 40.

All parts of the county have been hit - with the latest confirmed infections in Allerdale, Barrow, Carlisle and Copeland.

Scarlet fever is an infectious disease spread through close contact, and is most common between December and April.

As it is so contagious, particularly among children, parents are being warned to be on high alert for the signs.

These include a characteristic pinkish or red sandpapery rash.

Public Health England (PHE) has issued the latest figures - for the seven days up to Sunday.

Scarlet fever is a notifiable disease, meaning doctors must inform PHE of all suspected cases.

More tests will then be carried out and all confirmed cases are published weekly.

What is scarlet fever?

Symptoms of scarlet fever develop within a week of being infected.

Early signs include a sore throat, a headache, a high temperature (38.3C/101F or above), swollen glands in the neck and being sick.

This may be followed by a rash on the body, a red face and a white or red tongue.

It usually starts on the chest or tummy, before spreading to other areas.

It is made up of pink-red blotches that may join up.

It feels like sandpaper (this may be the most obvious sign in someone with dark skin).

It may be brightest red in body folds, such as the armpits or elbows.

It turns white if you press a glass on it.

Your GP will prescribe antibiotic tablets (or liquid for young children) to take for five or 10 days.

You or your child should start feeling better after a day or two but make sure you finish the whole course of treatment.

Scarlet fever usually clears up within a week, although the skin may peel for a few weeks after the other symptoms have passed.

The infection is contagious from before the symptoms appear until 24 hours after starting antibiotic treatment - or up to two or three weeks later if you don't take antibiotics.

There's no evidence to suggest that getting scarlet fever during pregnancy will harm your baby.

But it can make you feel unwell, so it's best to avoid close contact with anyone who has it.

If you do get symptoms of scarlet fever, see your GP for treatment.

The antibiotics used for scarlet fever are usually safe to take during pregnancy.

Keep your child away from nursery or school for at least 24 hours after starting antibiotic treatment – adults should stay off work for at least 24 hours after starting treatment.

Cover your mouth and nose with a tissue when you cough or sneeze – throw away used tissues immediately.

Wash your hands with soap and water often, especially after using or disposing of tissues.

Avoid sharing utensils, cups and glasses, clothes, baths, bed linen, towels or toys.
