Skin diseases, disorders and conditions include persons with boils, infected wounds, open sores, abrasions, or weeping dermatological lesions. We should avoid working where there is a likelihood they could contaminate healthcare supplies, body art equipment, or working surfaces. Workers skin should be free of rash or an infection and health care workers, tattoo artists, and caregivers should cover any sores with bandages to avoid the potential spread of disease. Let's talk a little bit about the skin anatomy. See, the skin is the largest organ of the body. And it contains blood vessels, sentry receptors, nerves, and sweat glands. It's made about the epidermis and the dermis. And it varies in thickness from one and a half to about four millimeters or more. Skin as the first-line defense against infection as long as it's intact. It's made up of the epidermis, the thick outer layer of the tissue that's strong and tough as long as it's intact. The dermis, which is the strong flexible second layer of connective tissue. That dermis is filled with blood vessels and any unclean tattoo or body art is it a high-risk activity for blood borne pathogens, because it involves multiple punctures of the skin to instill that pigment into the dermis. The hypo-dermis is just below the skin. And it's the fatty layer, also called the subcutaneous layer. Let's take a look at some commonly spread skin diseases. They include several types, but the first was going to be in the bacteria group. The first one is staphylococcus aureus, Otherwise known as staph. It's a bacterium commonly found on the skin and in the nose of some individuals. Most the time staph really doesn't cause any harm. The infections can look like little tiny pimples or boils or other skin conditions, and most are able to be treated. MRSA, the methicillin-resistant Staphylococcus aureus infection can look a lot like ordinary skin wounds or a boil or an infected sore. However the sore doesn't really seem to ever heal, and in fact sometimes it even looks like it gets worse. People contract MRSA by touching infected mucous membranes, skin, or other contaminated objects. And in the community most MRSA infections are limited to skin. More severe or potentially life-threatening MRSA infections occur most frequently among patients in health care settings. Now let's look at viruses. The most common is herpes simplex. It's generally found in the face, especially the lips, but it can also be seen on the scalp, or the arms, the neck, and upper chest Small round blisters when broken may secrete a little clear or yellowish fluid, and that fluid is highly contagious. People contracted herpes by touching infected saliva and those other mucous membranes or the skin. And then fungus the most common of these has several different names for about the same type of fungus. And that's athletes foot, jock itch, and ringworm. It causes red, patchy, flaky, itchy areas. It's contagious and is easily spread from one person to another. It spreads when infected area on another person or contaminated surface, like a shower or the floor of the shower is touched. Affected areas need to be kept clean and dry and there can be medications to help get rid of that infection once and for all. Some people with the following conditions are more prone to skin disorders. Healing may especially adversely be affected by receiving tattoos or body art. A history of hepatitis B or hepatitis C, HIV and AIDS, diabetes, history of hemophilia, or any other blood disorder, history of skin diseases or skin lesions, a history of allergies or adverse reactions to pigments, dyes, latex, etc., or an immune disorder.
