My whole family tested positive for covid, some ends the isolation today and others in 2 days, can we who left get covid from those who are still in isolation? in the case generating a reinfection??

If you all had COVID at the same time (or within a few days of each other), and some are done with their isolation period and the others have more time, you cannot get COVID from those same people. However, as you will not likely know for sure which variant you had, it is possible to get COVID from someone with a different variant. Hopefully, you are also all vaccinated and boosted if eligible!

The rate of re infection is low. If some members are symptom free, they should obtain a negative test prior to exposing outside individuals. If symptoms develop, please re test and obtain vaccination for all eligible members. Rest, stay well hydrated.
