198 1 AIDS was first discovered and diagnosed in the United States. The full name is "acquired immune deficiency syndrome", which is a transliteration of the English abbreviation Aids and has been translated into "AIDS" and "AIDS". There are two types: H Ⅳ-1and H Ⅳ-2, and each has subtypes. Different subtypes are prevalent in different regions, and the same subtype has certain differences in different regions. It is the human body infected with "human immunodeficiency virus".
Organisms are born with immune function. When bacteria and viruses invade the human body, even if they are sick, they can be cured under the condition of normal immune function. However, H Ⅳ attacks T4 lymphocytes, the central cell of the human immune system, making the human body lose its resistance.
