>What the PCR test was doing was taking a bit of the corona virus and amplifying it over and over to get a positive. Yes. 80% of swabs that tested positive at 30 cycles were culturable for covid. 3% of swabs that only tested positive at 35 cycles were culturable. Low numbers of virus = improble to develop infection. > Just about everyone has bits of corona virus because it's just versions of the common cold we've all had in our life time. No. OC-43 is a common betacorona virus that infects humans. Relative of sars cov 2. It is not likely to carry all of the sequences that the pcr test looks for, and presumably pcr test manufacturers are checking the database to see that those sequences are unique to sars cov 2. But there are multiple brands being used and I certainly havent verified them all personally. So lets say that the covid pcr tests positive when it encounters OC-43. People are only likely to get infected with it 1or 2 times in their lives. It accounts for approx. 15% of common cold cases. So it is far less common to catch than covid. The viral rna might survive a month or so in your body after infection. Maybe. So unless you had an active infection or a very recent infection, oc-43 rna would not just show up on a nasal swab. Do you see how increasingly hypothetical your explanation is becoming? I mean maybe its just covid,
