So, voted today, though in lieu of the poll worker sticker I would usually have with this, I have the medication that is my reason for not being a poll worker today.
"But how do you vote on election day (as opposed to absentee) and not walk into a building with people you would be infecting," you ask? Well, Ohio actually has this covered - it's called curbside voting.
First, drive to your polling location. OHIO IS A STICKLER ON HAVING YOU VOTE AT THE PRECINCT ASSIGNED FOR YOUR CURRENT ADDRESS. Next, you need to get the attention of the Precinct Election Officials (PEO's) inside; they may have a person or two assigned to keep an eye out, but it probably works better to ask another voter going inside to let them know they have a "curbside voter".
They will send two people out to help you, from differing parties, because auditing is important (and really more than half of a voting process, tbqh). They will then start by doing what they'd do at a roster table - ask for acceptable ID (Good news, US Passports are acceptable in Ohio now! Bad news, utility bills are no longer acceptable), ask you to state your name and current address, and write stuff down on a pink envelope. They will hand this pink envelope for you to look at and sign. They'll then head back inside for a bit.
After the PEO's verify you're in the poll book and haven't voted (or asked for an absentee ballot), you're in the right location, find and log the paper ballot they're bringing out to you, and hopefully sterilize things, they'll both come back out with the envelope and a paper ballot. Fill in the circles (completely, as instructed) as you wish, then fold the ballot loosely in half and stick it in the pink envelope. At this point, you seal the envelope, which you can lick but, as neither I nor the voting location manager felt like offering COVID-19 samples, a spare vote sticker was used in my case.
They then take the envelope back inside, and you're done! They both sign at the bottom as well, and do any further logging as necessary. If there are issues, such as "you moved or changed your name", you may end up voting provisionally, and may have some follow-up on a later day.
Remember that polls in Ohio close at 7:30 P.M. Also, note that this is a method where you are not in a line, so you will want to let them know you're out there before 7:30. But, if you didn't get an absentee ballot and you can't walk into the polling location, this is an option and I encourage you to vote however it has to happen.
