Here are some infectious diseases caused by microorganisms in the skin and eyes:
Acne is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty; the only exception being members of a few primitive Neolithic isolated tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
Trachoma is a condition occurs worldwide, mostly in rural settings in developing countries. It frequently affects children, although the effects of scarring may not be seen until later in life. While trachoma is rare in the United States, certain populations marked by poverty, crowded living conditions, or poor hygiene are at higher risk for this illness. It is spread through direct contact with infected eye, nose, or throat secretions or by contact with contaminated objects, such as towels or clothes. Certain flies can also spread the bacteria.
Conjunctivitis, also known as pinkeye, is an inflammation of the conjunctiva. The conjunctiva is the thin clear tissue that lies over the white part of the eye and lines the inside of the eyelid.
River blindness, also known as onchocerciasis, is a parasitic infection that can cause intense itching, skin discoloration, rashes, and eye disease that often leads to permanent blindness. It is spread by the bites of small black flies that breed in rapidly flowing rivers
Cellulitis is a common, potentially serious bacterial skin infection. Cellulitis appears as a swollen, red area of skin that feels hot and tender, and it may spread rapidly.
Gas gangrene develops suddenly. It usually occurs at the site of trauma or a recent surgical wound. About 1 in 5 cases occur without an irritating event. Patients most at risk for this usually have underlying blood vessel disease (atherosclerosis or hardening of the arteries), diabetes, or colon cancer.
Impetigo is a highly contagious skin infection that mainly affects infants and children. Impetigo usually appears as red sores on the face, especially around a child's nose and mouth. The sores burst and develop honey-colored crusts.
Keratitis is an inflammation of the cornea — the clear, dome-shaped tissue on the front of your eye that covers the pupil and iris. Keratitis may or may not be associated with an infection. Noninfectious keratitis can be caused by a relatively minor injury, wearing your contact lenses too long or other diseases. Infectious keratitis can be caused by bacteria, viruses, fungi and parasites.
