HIV
Tuberculosis
Candidiasis
MRSA
The Correct Answer is A
HIV stands for human immunodeficiency virus, a virus that infects and destroys CD4+ T cells, which are a type of white blood cell that coordinates the immune response against foreign invaders. HIV can cause acquired immunodeficiency syndrome (AIDS), which is a condition where the immune system becomes severely weakened and unable to fight off common infections and cancers. HIV can be transmitted through sexual contact, blood transfusion, needle sharing, or mother-to-child transmission.
