Hon Dr AYESHA VERRALL: If you're fully vaccinated and catch COVID-19, by day 10 of infection you'll pose a very low risk of passing on the virus. That's because the amount of viral genetic material declines faster in fully vaccinated people. So the isolation period for fully vaccinated COVID-19 cases in the community is reducing from 14 to 10 days and must include 72 hours symptom-free. The isolation period for partially vaccinated or unvaccinated COVID-19 cases will remain 14 days, including 72 hours symptom free. For fully vaccinated close contacts, they will need to self-isolate for seven days, while partially vaccinated or unvaccinated close contacts will be required to self-isolate for 10 days. Household contacts will isolate for 10 days regardless of vaccination status because this group is at highest risk of contracting the virus. These changes reflect the different transmission dynamics of the Delta variant.
