Question

6. How does AIDS virus enter the
human body?
Why does a person suffering from
AIDS have a very weak immune
system?​

Answer 1

Explanation:

HIV infects and destroys certain white blood cells called CD4+ cells. If too many CD4+ cells are destroyed, the body can no longer defend itself against infection. The last stage of HIV infection is AIDS (acquired immunodeficiency syndrome).

Answer 2

The Virus enters from blood as it is the main medium for it
It can be spread through sexual contact, blood transfusion or from infected mother to child ( in womb )
The person has a weak immunity system as the virus attacks mainly the immune system and the virus reproduces more, the immune system gets outnumbered. It is a fatal disease which cant be cured.
