Saliva for molecular detection of SARS-CoV-2 in pre-school and school-age children.

However, in children under 12, saliva sensitivity showed a trend towards a lower value in comparison to older subjects (80.9% vs. 89.7% in 12–17 years old and 91.4% in adults) and lower performance in comparison to NPS (80.9% vs. 94.1% for NPS), which was not the case in the other age groups (Table 2 ).

These analyses, however, did not reach statistical significance because of the limited number of subjects or the relatively poor reliability of reporting symptoms.
