HIV causes AIDS by progressively destroying helper T lymphocytes, critically impairing the immune system and leaving the individual vulnerable to fatal opportunistic infections.
HIV leads to AIDS by destroying helper T lymphocytes, severely weakening the immune system. This makes the body susceptible to opportunistic infections like pneumonia, which are the ultimate cause of death.
| Front | How does HIV lead to AIDS |
|---|---|
| Back | HIV attaches helper T lymphocytes, an uninfected person has 800-1200 helper T cells per mm³ but a person suffering with aids has as lower as 200. Without sufficient number of helper T cells, the immune system cannot stimulate production of cytotoxic cells or B cells to produce antibodies. Patients dont die from HIV they die due to their weakened immune system that leads to diseases such as pneumonia |
