Oh no! I hope you and your wife recover soon, Richard.
Pretty much what bcr229 said on the reptiles-and-covid front: while covid-19 has produced symptomatic cases in other mammals, it doesn't seem to impact reptiles and amphibians. From what I've heard, it's not common for viruses to jump between ectotherms (ie. cold-blooded animals) and endotherms (ie. warm-blooded animals) in general. Thankfully covid-19 doesn't seem to be an exception on this front.
