They can be a good mass monitoring system” Covid- 19 “which will allow to have, if not a daily data, at least one weekly”. Massimo Andreoni, scientific director of the Italian Society of Infectious and Tropical Diseases (Simit) and head of Infectious Diseases at the Tor Vergata Polyclinic in Rome, underlines this to Adnkronos Health, commenting on a possible extension of salivary tests at school, even beyond the ‘sentinel’ institutes .

“This type of” salivary “screening will be able to give us the real impact of the epidemic on the school and also allow us to discover outbreaks and quota them quickly”, adds Andreoni. In terms of effectiveness, salivary tests “have a good efficacy – says the infectious disease specialist – Of course they are second level tests compared to the PCR swab which remains the reference one. They have a lower sensitivity, but they are the right tool to apply in health monitoring. of a population as large as the school population can be “.
