Results of the logistic regression models for the effects of different parameters on the presence of SARS-CoV-2 RNA in environmental samples. Independent variables “environment—indoor” and “sampling site—transportation” are significantly associated with positivity rates in our sampling.
| Independent Variables | Levels * | Odds Ratio (95% CI) | p-Value |
|---|---|---|---|
| Neighborhood | Iñaquito | 1.81 (0.53, 7.09) | 0.36 |
| Surface material | Metal | 2.09 (0.57, 13.54) | 0.34 |
| Plastic | 1.95 (0.46, 13.33) | 0.41 | |
| Environment | Indoor | 3.36 (1.40, 9.35) | 0.01 ** |
| Sampling site | Parks | 0.21 (−4.72, 1.49) | 0.30 |
| Restaurants/Minimarkets | 1.29 (−1.26, 1.58) | 0.70 | |
| Shops/Business Premises | 0.96 (−1.47, 1.49) | 0.95 | |
| Transportation | 3.31 (0.06, 2.29) | 0.04 ** |
* Reference levels for each parameter are as follows: neighborhood (Belisario Quevedo), surface material (others), environment (outdoor), sampling site (other public places). ** represents parameters that are significantly associated with positivity rates in our sampling.
