If you're going to be technical, you can use full set-builder notation to express the above mathematical set. In set-builder notation, the previous set looks like this: The above is pronounced as the set of all x, such that x is an element of the natural numbers and x is less than 10. The vertical bar is usually pronounced as such that, and it comes between the name of the variable you're using to stand for the elements and the rule that tells you what those elements actually are.
Hand-dermatitis?: Red sores all over the palm of hands are more often caused by a contact allergy, hand-dermatitis (eczema), or infections such as scabies. The diagnosis is needed as the treatment will differ based on the cause. A certain virus can cause sores on the hands as a part of hand-foot-mouth disease.
A fever and sore throat are usually the first symptoms of hand, foot, and mouth disease. The characteristic blisters and rashes show up later, usually one or two days after the fever begins. Hand, foot, and mouth disease is often caused by a strain of coxsackievirus, most commonly coxsackievirus A16. The coxsackievirus is part of a group of viruses called Enteroviruses. In some cases, other types of Enteroviruses can cause hand, foot, and mouth disease. Viruses can be easily spread from person-to-person.
