Acne. Acne is the most common skin condition in the United States, affecting up to 50 million Americans annually. Acne usually begins in puberty and affects many adolescents and young adults.
Skin diseases are very common, and affect as many as one in three Americans at any given time. Common skin conditions include acne, contact dermatitis, benign tumors, cancers, atopic dermatitis (also called eczema), and psoriasis.
Common skin infections include cellulitis, erysipelas, impetigo, folliculitis, and furuncles and carbuncles. Cellulitis is an infection of the dermis and subcutaneous tissue that has poorly demarcated borders and is usually caused by Streptococcus or Staphylococcus species.
Is your skin itchy, oozing, or breaking out? Moles, psoriasis, hives, eczema, and recently associated Covid-19 coronavirus rashes are just a few of the more than 3,000 skin disorders known to dermatology. Changes in color or texture can result from inflammation, infection, or allergic reactions anywhere on the body.
The most prevalent of these conditions in 2004 were herpes simplex (based on seroprevalence), effects of sun exposure, contact dermatitis, hair and nail disorders, and human papillomavirus. To capture the wide range of skin diseases, this study also included diseases with low prevalence but often with severe burden.
A commonly spread skin disease that is a virus, is herpes simplex. This is generally found on the face, scalp, arms, neck, and upper chest. It's usually indicated by small round blisters when broken and they can secrete a clear or yellowish fluid.

Atopic dermatitis (eczema) is a condition that makes your skin red and itchy. It's common in children but can occur at any age. Atopic dermatitis is long lasting (chronic) and tends to flare periodically. It may be accompanied by asthma or hay fever.
Common causes of skin diseases include: Bacteria trapped in your pores or hair follicles. Conditions that affect your thyroid, kidneys or immune system. Contact with environmental triggers, such as allergens or another person's skin.
MRSA infections can appear as a small red bump, pimple, or boil. The area may be tender, swollen, or warm to the touch. Most of these infections are mild, but they can change, becoming deeper and more serious.
Atopic dermatitis, also known as eczema, is a non-contagious inflammatory skin condition. It is a chronic disease characterized by dry, itchy skin that can weep clear fluid when scratched. People with eczema also may be particularly susceptible to bacterial, viral, and fungal skin infections.
"Another common rash form we are seeing with COVID-19 infection is a varicelliform rash or chickenpoxlike rash. The rash will be small round ovals on the skin with a center that shows a bit of fluid, like a bubble or small blister. It's similar to what we call a 'dewdrop on a rose petal' seen in chickenpox.
Impetigo: A Skin Rash Caused by Bacteria
Scratching the rash and then touching other areas of the body, or other people, will cause it to spread.
Impetigo starts as a red, itchy sore. As it heals, a crusty, yellow or “honey-colored” scab forms over the sore. In general, impetigo is a mild infection that can occur anywhere on the body. It most often affects exposed skin, such as around the nose and mouth or on the arms or legs.
The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. FUN FACT: The skin is the largest organ of the human body! It accounts for about 15% of your body weight, and the average person has about 300 million skin cells.
Normally as the body sheds skin cells, the keratinocytes rise to the surface of the skin. When someone has acne, the hair, sebum, and keratinocytes stick together inside the pore. This prevents the keratinocytes from shedding and keeps the sebum from reaching the surface of the skin.
