Hey, I had COVID in September and sore throat/hoarse voice were the main symptoms I had - weird considering they aren’t listed as official symptoms. Definitely try and get a PCR test if you can, when I got mine I ordered it to my house, it came the next day, then got the results like 2 days after I sent it back. Also keep doing lateral flows every day with the kind of work you do, I had symptoms for about 4 days while testing negative
