The CDC has changed the definition of a close contact. It is defined as a cumulative total of 15 minutes or more over a 24 hour period.
"Someone who was within 6 feet of an infected person for a cumulative total of 15 minutes or more over a 24-hour period* starting from 2 days before illness onset (or, for asymptomatic patients, 2 days prior to test specimen collection) until the time the patient is isolated." The full definition can be viewed here: www.cdc.gov/coronavirus/2019-ncov/php/contact-tracing/contact-tracing-plan/appendix.html#contact Please contact your school nurse with any questions. |
