Vaccinated students are often excluded from close contact definitions, and we are seeing an increasing number of cases where a student who has had Covid 19 in the previous 90 days is also excluded from close contact rules.    4. In our [October 11th report](https://t.sidekickopen87.com/s3t/c/5/f18dQhb0S7kF8cN1-lW4Z38YH2zGCwVN8Jbw_8QsRtKMp0zlYQBvXjW16gGyW4Fjgc_101?te=W3R5hFj4cm2zwW3T1k3k1Jx5_0W3C9qYl3Fbt5SW4cHc2L43SH72W49HR8w3K8JY_W45M-pK3JD_xdF1G93dkmFDR1&si=8000000005008834&pi=32ce0ad5-788e-4b4e-a54c-00faa1521d5b) we outlined some test-to-stay programs in the Northeast.  Here are examples from other parts of the US: - In California, [Long Beach](https://t.sidekickopen87.com/s3t/c/5/f18dQhb0S7kF8cN1-lW4Z38YH2zGCwVN8Jbw_8QsRtKMp0zlYQBvXjW16gGyW4Fjgc_101?te=W3R5hFj4cm2zwW4mKLS-3ZS_0LW3R3bRn4cg8qDW4ff2Kk45LMtqW3_SNwq4cgx4yW4mJ3xZ43T4NQW49RLJN3ZV6nwW3M5bF_49RLJNW3ZV8LY2dMF812123&si=8000000005008834&pi=32ce0ad5-788e-4b4e-a54c-00faa1521d5b) is implementing a modified quarantine plan where exposed, asymptomatic students attend school, are tested twice weekly, and must refrain from extracurriculars. [Alameda County, CA](https://t.sidekickopen87.com/s3t/c/5/f18dQhb0S7kF8cN1-lW4Z38YH2zGCwVN8Jbw_8QsRtKMp0zlYQBvXjW16gGyW4Fjgc_101?te=W3R5hFj4cm2zwW4mKLS-3z8nCpW1JDwVN1Lm79Sw3JFRzg4M-2&si=8000000005008834&pi=32ce0ad5-788e-4b4e-a54c-00faa1521d5b) outlines both modified quarantine and "shortened" quarantine, an option where at-home quarantine can be reduced to 8 days if a student is tested by Day 5. [Stanislaus, CA](https://t.sidekickopen87.com/s3t/c/5/f18dQhb0S7kF8cN1-lW4Z38YH2zGCwVN8Jbw_8QsRtKMp0zlYQBvXjW16gGyW4Fjgc_101?te=W3R5hFj4cm2zwW4mKLS-4cQgwdW4hJVmN41pqDwW1S0DLm1JH0QfW2v_2c249M7ZKW1Lm8qq4fDXYrW3FbtXB3GGyXGn4cQhc81X3&si=8000000005008834&pi=32ce0ad5-788e-4b4e-a54c-00faa1521d5b) outlines modified quarantines and also references California rules that vaccinated individuals are not subject to quarantines after exposure. - In [Fargo, ND schools](https://t.sidekickopen87.com/s3t/c/5/f18dQhb0S7kF8cN1-lW4Z38YH2zGCwVN8Jbw_8QsRtKMp0zlYQBvXjW16gGyW4Fjgc_101?te=W3R5hFj4cm2zwW4mKLS-3M0hrkW43m-6J1S0FJzW1JH0Qf2YCfp3n1L6BdT113&si=8000000005008834&pi=32ce0ad5-788e-4b4e-a54c-00faa1521d5b) masked asymptomatic close contacts don't need to quarantine (or test) at all, and neither do vaccinated close contacts.  Contacts that weren't wearing masks can attend school if they agree to test every other day. - In Maricopa County, AZ both [Gilbert Schools, AZ,](https://t.sidekickopen87.com/s3t/c/5/f18dQhb0S7kF8cN1-lW4Z38YH2zGCwVN8Jbw_8QsRtKMp0zlYQBvXjW16gGyW4Fjgc_101?te=W3R5hFj4cm2zwW4mKLS-3P28c0W3K8R9y3F7y_5W3Z-Z1x3K9y3JW3T3QQ92vZm8yW4hJ3ms3zh2hzW2jXVdQ3JSHv94q7tJ1&si=8000000005008834&pi=32ce0ad5-788e-4b4e-a54c-00faa1521d5b) and [Deer Valley Unified School District](https://t.sidekickopen87.com/s3t/c/5/f18dQhb0S7kF8cN1-lW4Z38YH2zGCwVN8Jbw_8QsRtKMp0zlYQBvXjW16gGyW4Fjgc_101?te=W3R5hFj4cm2zwW4mKLS-3HcYGDW3GGZZR3NB-cLW3P0nYw1Q6Bjt0&si=8000000005008834&pi=32ce0ad5-788e-4b4e-a54c-00faa1521d5b) provide quarantine exceptions for both vaccinated students and any student who has had Covid 19 in the previous 90 days.
