The main risk from the dreaded virus when playing golf I see as handling the ball after it has been in the hole. Slight, I know, but a risk nevertheless. I carry with me a plastic bag with three antibacterial wipes inside, liberally squirted with antibacterial fluid. I pick my ball carefully out of the hole, put hand & ball into the bag & give it a good twirl. Hopefully this does the trick. It also gets the ball really clean.
