Development of the 13 cases and testing over time. Cases 1&2 were initial suspected index cases, confirmed by PCR on Day 2 and LAMP on Day 4. A further 4 cases were detected by universal PCR testing on Day 3, then LAMP on Day 4. On Day 4, 8 cases were confirmed by both universal RT-PCR and LAMP, with 2 new cases identified on RT-PCR only and 3 further cases on LAMP only (discrepant results in light yellow)
