A group of viral infections that cause sores on the mouth (oral herpes) or genitals (genital herpes). There are two types of Herpes Simplex Virus:
Herpes Simplex Virus Type 1 is the most common form of herpes that affects most people at least once during childhood.
Herpes Simplex Virus Type 2 is sexually transmitted either to the genital area or mouth. About one in five adults in the U.S. has this form of the herpes virus, although many people don't know they have it.
Chicken pox is a common illness, particularly among children. It is characterized by itchy red spots or blisters all over the body. Chicken pox is caused by Herpes Varicella Zoster virus. It is highly contagious, but most cases are not dangerous.
Chicken pox can be passed on from two to three days before the rash appears until the blisters are crusted over. It spreads from exposure to infected people who cough, sneeze, share food or drinks or by touching the blisters. It is often accompanied by a headache, sore throat and possibly a fever. The incubation period (from exposure to the first appearance of symptoms) is 14 to 16 days. When the blisters crust over, they are no longer contagious and the child can return to normal activity. This normally takes about 10 days after the initial appearance of symptoms.
Cellulitis is a common bacterial skin infection that is caused by either Staphylococcus or Streptococcus bacteria. Both of these bacteria occur naturally on the skin. A break or cut in the skin causes the bacteria to enter the body, which leads to an active infection. Cellulitis most often occurs from:
- cracking or peeling skin between the toes,
- insect bites or stings, and
- a skin cut, break or trauma
Cellulitis appears as a swollen red area of skin that is tender and hot to the touch. Symptoms include chills, fever, muscle ache, fatigue, pain or tenderness in an area with a skin rash or sore. The redness increases in size as the infection spreads. It typically comes on suddenly and spreads quickly. Cellulitis can arise anywhere on the body but usually appears on the face or legs. Be sure to contact your dermatologist as soon as you observe these symptoms to start an effective treatment.
Also known as skin abscesses, boils form as a result of a cut or break in the skin, which leads to a bacterial infection. They are characterized as a red, tender area with a painful, pus-filled center that can open spontaneously or by surgical incision. Some boils are caused by ingrown hair. Others are caused by blocked sweat glands, which occurs with some types of cystic acne.
Anyone can get a boil. They grow quickly and are usually painful until they drain. However, left alone a boil will naturally come to a head and burst open, allowing the pus to drain and the skin to heal. People with weakened immune systems are more susceptible to boils than the general population.
Shingles is a painful rash that is caused by the varicella zoster virus. It usually appears as a band or strip of blisters on one side of the body that goes from the spine around the front to the breastbone. Shingles derives from the same virus that causes chicken pox. After having chicken pox, the virus lies dormant in nerve tissue underneath the skin. Years later, and with no known reason, it reactivates and causes shingles.
Shingles is contagious and can easily pass through touching from one person to another. The virus develops into shingles for people who have had chicken pox and develops into chicken pox for those who have not had it. Shingles appear most frequently among older adults (age 60+) and in people with compromised immune systems.
Scabies is a harmless but very itchy and highly contagious skin condition caused by mites that burrow into the skin and lay eggs. Symptoms include a severe itch, often worse at nighttime, and thin burrow tracks made of tiny bumps or blisters on the skin. Humans are allergic to the mites, which is what causes the itching.
Typically, scabies appear in the folds of the skin, such as the armpits, around the waist, inside the wrists, between the fingers, on the soles of feet, on the back of knees or on inner elbows. In children, they more commonly appear on the face, scalp, neck, palms and soles. Scabies is spread through direct contact with an infected person or by sharing clothing and linens. It is so contagious that frequently when one person in a family is diagnosed with scabies, all family members are treated.
