Kasper, the lucky guy, managed to catch some skin virus. I do not know where he caught it from, but I do not think it was very common.
It is a huge hassle to take care of, and if left to run its coarse, takes three years to clear up.
So we got some help from the dermatologist, who put a poison on each spot. This turns them all into blisters, then they turn into scabs.
This is why Kasper is covered in bandages here.
Do not worry, it does not hurt him at all, but it does take more then one treatment, so the good times have just started!
