Acne – Definition

Acne occurs when the pores of the skin become clogged, inflamed, and sometimes infected. These clogged pores can result in blackheads, whiteheads, or pimples. Acne tends to occur in teenagers, but can also occur in adults.

Acne – Causes

Acne starts in the skin’s sebaceous glands. These glands secrete an oily substance called sebum. The sebum normally travels through a tiny hair follicle from the gland to the skin’s surface. Sometimes the sebum becomes trapped, mixing with dead skin cells and bacteria. This causes clogged pores called comedones.

HIV and AIDS – Definition

HIV is a virus that attacks white blood cells called helper T cells (CD4). These cells are part of the immune system. They fight off infections and disease. As a result, an HIV infection can leave you vulnerable to severe illnesses.

AIDS is a late stage of HIV infection. It reflects severe damage to the immune system. One or more opportunistic infections will also likely exist. This is a type of infection that only occurs in people with compromised immune systems.
