Starting Tuesday morning anyone arriving in the UK is required to provide a pre-booked negative PCR or lateral flow test taken no earlier than 48 hours before departure. This applies to vaccinated passengers and children aged 12 and above. The UK Health and Security Agency indicates that the window between infection and infectiousness may be shorter for the Omicron variant, which increases the efficacy of pre-departure testing.
