The hand, foot and mouth disease is a common viral infection, mainly in young children
The disease is contagious and may affect adults or older children – albeit much less often.
Schools have reported the virus across the UK, including Somerset, Gloucester and Manchester.
Parents were asked to look for signs of the virus and leave their children at home in the event of an infection.
Janine Parry, Pediatric Nursing Practice, Pennine Care NHS Foundation Trust, said, "Over the last few weeks, we've seen an increase in the number of children who had cases of hand, foot and mouth in our clinics.
"Hand, foot and mouth are a common viral infection in children under the age of 10, which is usually mild and resolves by itself within a week to 10 days.
"The best advice is to keep your child at home and keep him hydrated until he feels better. Soft foods and acetaminophen can also help if your child has sore throat and sore throat.
"If the symptoms do not improve after one week to 10 days, you should consult a suitable doctor.
"You should also seek advice if your child shows signs of dehydration, has seizures, has very high temperatures, is unusually tired or unbearable, or if his skin becomes painful, red, swollen, or hot," she told the Manchester Evening News ,
The earliest symptoms of hand, mouth and mouth disease include sore throats, high fever and not eating, the NHS said.
After a few days, patients usually develop painful mouth ulcers that make eating or drinking difficult.
In other parts of the body, red spots may appear on the hands and feet. They can also develop into painful blisters.
The patches that can turn into a rash could also appear on the knees, elbows, buttocks, or genitals.
The symptoms are usually similar in children and adults, but more serious in the elderly.
If you become infected with a disease of the foot, hand, and mouth, it is best to let the infection go.
Currently, there is no treatment for the disease, so drugs work to reduce the symptoms.
Drink plenty of fluids to prevent dehydration and drink sour fruit juices.
The painkillers, including acetaminophen and ibuprofenites, can help with sore throats, the NHS added.
If you are concerned about the signs and symptoms of the disease, talk to a pharmacist.
However, you should consult a doctor if the symptoms do not improve within 10 days or if you are pregnant.
