Question

When learning about hiv/aids, the student should be able to differentiate the two subtypes of virus by which characteristic?

Answer 1

There are two types of HIV viruses, HIV1 and HIV2.

HIV1 is most commonly found (HIV2 is located in Wes America).

HIV1 is usually more likely to progress and get worsen, so the level of immune system activation of the host is higher.  

HIV1 has lower CD4 counts and plasma viral loads are higher.
