Ah so you survived the plague. Your problems are just beginning. I’d recommend the old British tv series Survivors for a start.
A frozen dead body will be just as contagious as a freshly dead one when it thaws out. In Breaking Bad they put the bodies in barrels labeled toxic waste and poured acid on them. In the Black Death they just dumped the bodies into mass graves and shoveled lime on them. Not to close to their wells I hope. I wouldn’t ever let a dog or cat lick my face or hands or clean up the waste from one. Step in doggy human poo immerse your boots in bleach or at least 70% Al. Time to get out the chem warfare manual I guess. No handshakes and eye mask not glasses.
