Following the Texas Education Agency recommended protocols, contact tracing is conducted by HISD staff any time a positive case is reported. Anyone with symptoms and/or a positive test is quarantined. . All students and staff  identified as exposed through qualified close contact are quarantined. Exposed does not mean that the person has COVID-19 infection. it means that they have been exposed to someone who has  reported symptoms and/or positive test. Following the HISD Protocol, the exposed person is then quarantined. See the documents linked below to see what qualifies as close contact warranting a quarantine status for anyone exposed.
