diffrence between HIV1 & HIV2

Question

I want to understand the difference between HIv1 and HIV2 as my friend has been tested positive for HIV1. does this mean the complications are less?

Answer

Although in the same family, these viruses are genetically distinct. In addition, people with HIV-2 infection progress much slower than patients with HIV-1. If required most HIV-1 drugs will work against HIV-2 infection.
