Do hospitals release severe patients back to home and family including kids with large replicating viral loads still very likely to be infectious without ordering strict isolation from even family for certain number of days when first returning home? I wouldn’t think so, but even if out of abundance of caution any defined contact within what’s listed on discharge info you posted is what school’s policy should follow (14 days from whatever is most recent contact meeting defined criteria your kids had with her within the 3 days after discharge and/or within of the 10 days first positive test or after start of symptoms whichever discharge papers actual lists). I don’t remember time frame of wife’s hospitalization and discharge in relation to the 3 days after discharge and the 10 days after positive test listed on her discharge paperwork you mentioned.

From CDC severely ill patients only might need to stay home longer than 10 days. It’s up to doctor which i assume is what’s on discharge papers.

People who are severely ill with COVID-19 might need to stay home longer than 10 days and up to 20 days after symptoms first appeared. Persons who are severely immunocompromised may require testing to determine when they can be around others. Talk to your healthcare provider for more information. If testing is available in your community, it may be recommended by your healthcare provider. Your healthcare provider will let you know if you can resume being around other people based on the results of your testing.

Also from CDC footnotes - in one study 95% of severe and sometimes also immunocompromised patients’ specimens didn’t have replicating virus after 15 days. That’s just from specimens tested not actual infections caused. Another study listed by CDC found no actual infections developed from high risk household and hospital contacts 6 or more days from start of symptoms (i assume some precautions were still followed even in households but don’t know how high risk defined).

quote:
Recovery of replication-competent virus between 10 and 20 days after symptom onset has been documented in some persons with severe COVID-19 that, in some cases, was complicated by immunocompromised state (van Kampen et al., 2020).

However, in this series of patients, it was estimated that 88% and 95% of their specimens no longer yielded replication-competent virus after 10 and 15 days, respectively, following symptom onset.

A large contact tracing study demonstrated that high-risk household and hospital contacts did not develop infection if their exposure to a case patient started 6 days or more after the case patient’s illness onset (Cheng et al., 2020).
