Update and further question.
Mom and Dad fully vaccinated. 4 kids: 9(A),6(B),6(C),4(D), unvaccinated, of course.
9/24-9/26: Mom out of town
9/27: Mom returns. Mild symptoms at night.
9/28: Mom loses sense of smell, complete isolation from the rest of us begins, family quarantine begins
9/30: Mom gets test results back confirming COVID, other 5 all get rapid tested - negative. Isolation continues
10/2: Kid B and kid D test positive (A, C and Dad negative). Mom isolation is ended, entire family is now quarantining together. Mild symptoms start for Kids B and D.
10/3: Mild symptoms start for Kids A and C, Kid B has more severe symptoms. Kid A tests negative again, Kid C tests positive. Dad still negative and asymptomatic.
10/6: Mild symptoms start for Dad.
10/7: More serious symptoms start for Dad. Kid A tests positive.
10/10: Dad still feeling symptoms, Kid A still feeling symptoms. Everyone else feels fine.
So summarizing by individual:
Mom:
Vaccinated. First symptoms 9/27; positive test on 9/28 (rec’d 9/30); most symptoms done by 10/2; 10/10 is 14th day since first symptoms.
Dad: Vaccinated. Mild exposure on 9/27. Extreme exposure starting 10/2. Negative tests on 9/30, 10/2, 10/3, 10/7. Asymptomatic 9/27-10/6. Mild symptoms starting 10/6.
Kid A(9): Unvaccinated. Mild exposure on 9/27. Extreme exposure starting 10/2. Negative tests on 9/30, 10/2, 10/3. Very mild symptoms start on 10/3. Still symptomatic on 10/10. Positive test on 10/7.
Kid B(6): Unvaccinated. Mild exposure on 9/27. Extreme exposure starting 10/2. Negative test on 9/30. Positive test on 10/2. Symptoms gone after 36-48 hours.
Kid C(6): Unvaccinated. Mild exposure on 9/27. Extreme exposure starting 10/2. Negative tests on 9/30, 10/2. Symptoms start on 10/3, persist for 24-36 hours. Positive test on 10/3.
Kid D(4): Unvaccinated. Mild exposure on 9/27. Extreme exposure starting 10/2. Negative test on 9/30. Positive test on 10/2. Mild symptoms gone after 24-36.
So here is my interpretation of the CDC recommendations:
Mom: Fully done with quarantine. First symptoms were 14 days ago. Fever has been gone for more than a week.
Dad: Trickiest one. Still has not tested positive. I would say 10 days from 10/6, or 7 days from 10/6 if another negative test on 10/12.
Kids B and D: Quarantine ends 10 days from 10/2 (10/12 off quarantine) assuming no fever in past 24 hours.
Kids A and C: Quarantine ends 10 days from 10/3 (10/13 off quarantine) assuming no fever in past 24 hours.
Does continued exposure to others (e.g., Dad) change any of this?
