It's not going to blow over any time soon, so if you really want to wait for it to blow over, you're probably not going to be getting any new cubes for many months.
Alternatively, if you're worried but still want to get new cubes, all you have to do is to wash your new cubes with soap and water. Alcohol of sufficiently high concentration works too, if you have that. (Depending on your level of paranoia, you can wash the core too, but make sure to dry it promptly to prevent it from rusting.)
Also, wash your hands regularly, etc. etc. Not observing proper hygiene is a way bigger risk factor than imported products from China carrying the virus. (Looks like you're American and it doesn't quite seem like the US of A is doing very well at containing the disease!)
