TTV and ReDoV prevalence and load in the saliva samples, grouped by SARS-CoV-2 RNA status.
| Parameter | SARS-CoV-2 Negative |
SARS-CoV-2 Positive |
Total |
|---|---|---|---|
| Saliva samples examined (No.) | 326 | 122 | 448 |
| TTV DNA positive (%) | 238 (73) | 87 (71) | 325 (72) |
| ReDoV DNA positive (%) | 167 (65) a,b | 63 (52) c | 230 (61) d,e |
| TTV DNA load (Log copies/mL ± 95% CI) | 4.6 (4.4–4.8) | 4.7 (4.3–4.8) | 4.6 (4.4–4.7) |
| ReDoV DNA load (Log copies/mL ± 95% CI) | 4.4 (4.1–4.6) | 4.5 (4.0–4.7) | 4.4 (4.2–4.5) |
CI, confidence limit. a Value calculated on 255 of 326 (78%) SARS-CoV-2-negative saliva samples. b Statistically significant to 63 ReDoV DNA positive in SARS-CoV-2-positive group at p = 0.0098 (Chi-Square test). c Statistically significant to 87 TTV DNA positive in SARS-CoV-2-positive group at p = 0.0099 (Chi-Square test). d Value calculated on 377 of 448 (84%) saliva samples. e Statistically significant to 325 TTV DNA positive in the Total group at p = 0.0004 (Chi-Square test).
