Everitt, 19, was struck down by the viral infection the week before Christmas and was ordered to spend three weeks "doing absolutely nothing".
He has since returned to training but is restricted to running and non-contact work, with doctors keen to protect his spleen, which can become enlarged during the infection.
"I'm still not allowed to do contact for a couple of weeks, but I get another blood test in early February to see if everything is back to normal," he said on Thursday, just over two weeks before the Dogs' opening NAB Cup game against Essendon in Darwin.
"I had one about two weeks ago and all signs are good.
"Hopefully I'll be right for round two in the NAB and be up for selection."
Everitt said the debilitating illness took control of his life over the festive period and forced him to spend most of his days resting.
"I found out just before Christmas, probably the week before we left for our break," he said.
"I got back to training after Arizona and I had these massive lumps on my neck, so I thought I better go and figure out why.
"It was pretty flattening at the time and it knocked me around a bit. I was sleeping about 17 hours a day in the first week.
"I got onto it early though and I'm getting over it pretty quickly."
Everitt is confident the fitness base he worked so keenly on before the Dogs' pre-season officially resumed will remain intact.
"It didn't do much to my fitness at all. I'm running now and I feel pretty fit," he said.
"I haven't lost too much strength, and I'm pretty surprised and so are the coaches, so hopefully it all comes back pretty quickly."
