Universal testing of all students and staff in K-12 schools is not being recommended by the US Centers for Disease Control and Prevention.
But the CDC said schools should test everyone who has had close contact with someone positively tested for Covid-19, as well as those showing symptoms.
“It is not known if testing in school settings provides any additional reduction in person-to-person transmission of the virus beyond what would be expected with implementation of other infection preventive measures (e.g., social distancing, cloth face covering, hand washing, enhanced cleaning and disinfecting),” the CDC said in the guidance. “Therefore, CDC does not recommend universal testing of all students and staff.”
Anyway, schools may lack infrastructure to support the testing and follow up, students, parents and staff may balk at getting tested, and testing could cause disruptions, the CDC said.
If schools do decide to implement a testing plan, the CDC said that they should work alongside other agencies, such as state and local health authorities, to work out what would be the best strategy for them.
