| | Basic Immunology
Arthritis and asthma are diseases of the immune system caused by the body's hypersensitivity to certain substances. A variety of drug therapies today can strengthen the immune system and prolong the life of the AIDS patient, but there is currently no cure.
AIDS leaves the body susceptible to infections that a healthy patient would easily combat with his or her own antibodies. The treatment of disorders as simple as common allergies and as complex as AIDS all fall under the immunology category.
. Since the immune system protects the entire body, AIDS leaves the entire body vulnerable and opportunistic infections can attack multiple body organs, severely weakening the patient. If the WHO guesses wrong, and we are invaded by flus for which we have not received artificially induced immunities, a lot of people will come down with the flu. One of the most intractable of immunology's problems today is a disease that attacks the immune system itself, AIDS, or Acquired Immunodeficiency Syndrome, caused by the Human Immunodeficiency Virus (HIV). Immunology dates back to ancient civilizations, as it has long been known that certain individuals are naturally immune to some diseases, and that survivors of certain diseases are immune to the disease they survived.
Immunology is both the study of the human immune system and the field of medicine that treats diseases of the immune system.
