Table 1.
Comparison of positive rates of 11 respiratory pathogens in 2019 and 2020, the detection rate of InfA was 5.6% in 2019, but none in 2020
| Pathogens | 2019 N = 2298 |
2020 N = 3398 |
X2 | P |

| Influenza B virus (InfB) | 3 (0.1%) | 1 (< 0.1%) | 0.8164 | 0.3662 |
In contrast, the detection rates of RSV, HPIV, and HMPV in 2020 increased compared with those in 2019, other pathogens, such as HBoV, InfB, and HCoV, showed similar detection rates between 2019 and 2020
