That's very likely - also actually, I was very sick in January 2020 and so was everyone around me, except my son who was 9 at the time. There is a good chance that was covid, but I never lost my smell or taste so it could have also just been a flu. I just don't have a positive test result to show anyone. But yeah, I don't get sick very often at all, and around Christmas 2019 I had caught strep so I was on antibiotics, which will weaken your natural immune system to a certain degree. That was quite a 1-2 punch - I get over strep only to catch a virus. But the black elderberry syrup was a big help!
