Dark bee and viruses.

[Antipodes]

NSW DPI Bee Biosecurity Officers visited New Zealand where varroa mites are established and I was looking at the video below. At around the 1:20 minute to 1:35 minute mark a couple of dark bees appear. One of the biosecurity officers can be heard saying that the dark bee is "a virus affected bee".
I presume that there are a number of viruses that can cause bees to be dark and hairless like that and I'm after some views and advice please about which ones and the most likely suspects.

Chronic bee paralysis virus springs to mind but old bees lose their hair and look shiny too.

Thanks Dani.
So with those couple of bees in the video, could you say one way or the other with any certainty? I think the one he sees has almost no apparent "colour" segmentation in the abdomen.

I’m no expert but I wouldn’t worry about two bees but obviously keep an eye open. They say there are two types of CBPV. Shaking ataxic bees. Shiny black bees. I think most infections are both. It’s easy enough to spot shaking bees on the top bars that often don’t go down when you smoke them.
