Good news, my dad doesn't have leukemia. Turns out is something called megalovirus. About 95% of the people in the country have it. You get it as a child, common cold like symptoms, then goes dormant. Something triggered it in my dad. He just has to wait it out. Should be all gone in a few more weeks. It does mimic most of the signs of leukemia.

glad your dad is ok.
