Key points

Martinique

After a generally stable trend that remained at a high level for six consecutive weeks (August 2021–13), all surveillance indicators showed a marked increase last week (2021–14). Incidence rates (+45%) and positivity rates (+2 percentage points) are rising, exceeding their respective alert thresholds, despite a testing rate that also increased (+19%) compared to week 2021-13. In private practice, the number of consultations also rose (+70%). In hospitals, activity has intensified with a higher number of new hospitalizations, including those in intensive care. The UK variant (20I/50Y.V1) is actively circulating in the archipelago (>90% of screened RT-PCR tests). The new clusters involve temporary gatherings of people (religious services, private gatherings, parties) that took place during the Easter holidays. The effective reproduction number (Rt) calculated from SI-DEP data for week 2021-14 was significantly greater than 1: 1.21 [1.12–1.32].
