Ringworm, also known as dermatophytosis, dermatophyte infection, or tinea, is a fungal infection of the skin.

“Ringworm” is a misnomer, since a fungus, not a worm, causes the infection. The lesion caused by this infection resembles a worm in the shape of a ring — hence the name.

Ringworm is usually specifically used to describe tinea corporis (ringworm of the body), although it can sometimes be used to describe tinea infection in other locations, such as tinea cruris (ringworm of the groin).

Ringworm infection can affect both humans and animals. The infection initially appears as red patches on affected areas of the skin and later may spread to other parts of the body. It may affect the scalp, feet, nails, groin, beard, or other areas.

A fungal infection rarely spreads below the surface of the skin to cause serious illness. But people with weak immune systems, such as those with HIV/AIDS, may find it difficult to get rid of the infection.

Sunburn is caused by too much exposure to ultraviolet (UV) light. UV light may be from sunlight or artificial sources, such as sunlamps and tanning beds.

Intense, repeated sun exposure that results in sunburn increases your risk of other skin damage and certain diseases. These include premature aging of skin (photoaging), precancerous skin lesions and skin cancer.

Despite health warnings about sun damage, many of us still subject our skin to the sun's burning rays.

More than one-third of adults and nearly 70% of children admit they've gotten sunburned within the past year, according to the CDC.

When you get a sunburn, your skin turns red and hurts. If the burn is severe, you can develop swelling and sunburn blisters. You may even feel like you have the flu -- feverish, with chills, nausea, headache, and weakness.

Have you ever noticed how quickly your feelings can change? One day you might feel happy because you made a new friend. The next day you might feel sad because your friend seems to like someone else better.

Understanding how and why your feelings change is part of growing up. Sometimes feelings can be very confusing.

Not all feelings are good, but it is still okay to have them. It is also okay to let people know how are you feel – and why you feel that way. But it is not okay to do whatever your feelings make you feel like doing. It is not okay to hit someone or call someone a name because you are angry.

You tell people how you are feeling in many ways. You tell them with your words, your face, and what you do with your body. When you are angry you might want to frown, make a fist, or yell. But you might find it more helpful to talk.

If your feelings upset you, talk to someone you trust. You will learn that everyone feels the same way you do, at some time or another.

As you grow, you think and wonder. You think of questions, and you try to find the answers. You might wonder why it does not hurt to cut your hair. Why do you yawn? What, exactly, do your fingerprints look like?

You search for the answers to these questions by using your eyes, reading books, using the computer, or asking people. Believe it or not, when you do this searching, you are doing what scientists do.

You find out from looking through a magnifying glass what your fingerprints look like. You find out from reading an encyclopedia that cutting your hair does not hurt because there are no nerves in your hair. You feel pain only where there are nerves. You find out from asking your dad that you yawn because you are tired. The gulps of air you take in as you yawn bring extra oxygen into your body and make you feel more awake.

Some things are fun to think about. Some are confusing. You might wonder why you were born. What does being alive mean, and why do people die? You might ask your parents, teacher, or a friend. Try to find answers together.

The more you learn, the more you will want to know!

The first time you went to school, you did not know what to expect. There were so many new faces. You may have been a little scared. Soon you learned things and made friends.

The first day of any new school year is sometimes like that very first day. It’s exciting. You wake up early in the morning. You eat breakfast quickly. You gather up your new school supplies. You do not want to be late.

Lots of questions race through your mind. What will your new teacher and classroom be like? Where will you sit? What new things will you learn?

Maybe you have not seen your school friends all summer. There will be a lot to talk about. There might be new children in the classroom-new friends. Maybe you will be the new child in the classroom. If so, you might be a little scared or shy. Will the other children like the things you like? What if you get lost in the school? These are normal feelings.

A new school year is always a little strange at first. Soon everything will become friendly and familiar. In time, you will feel right at home.
