The Countess of Wessex stepped out for her first in-person public engagement after leaving quarantine last week.
Sophie, 55, attended a special service at Westminster Abbey in London on Monday evening, where she gave a reading.
The Sung Eucharist for All Souls' Day service was held in partnership with Loss and HOPE, a coalition of organisations helping churches of all denominations across the UK to support the bereaved.
In early October, the Countess took the decision to self-isolate after coming into contact with someone who had tested positive for coronavirus.
