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.

Cystic Fibrosis – Definition

Cystic fibrosis (CF) is an inherited disease. The defect occurs in epithelial (lining) cells. These cells normally create a mucus. The mucus is a vital tool for many organs. CF causes the cells to produce a very thick and rubbery mucus. This most commonly causes:

  • Obstructions and infections of the lungs and airways
  • Malabsorption in the gastrointestinal system (stomach and intestines)
  • Failure to thrive (growth problems)
