Boreoeutheria

Boreoeutheria (also Boreotheria) are mammals that are the third superorder of placental mammals.^[1] The other two groups are Afrotheria and Xenarthra.

They evolved on the northern supercontinent Laurasia after it split from Gondwana when Pangaea broke up.

Lentivirus, or Retrovirus can affect these mammals, as well as humans which are part of this magnorder.
