My own grandmother passed away earlier in the year, she was 95 and had many issues but also only tested negative.  She got her wish to die in her sleep.  The following day, the home she was living in listed her and the 2 others that died that day as having covid.    Again, she was 95 and not exactly running around, but she definitively was not infected, not sick, but still she counted.  When a relative confronted them, they said that because the other 2 had tested positive hers was an 'assumed positive'.
