Key points

Guadeloupe

The spread of SARS-CoV-2 accelerated in S25. This acceleration follows several weeks of relative stability in virological indicators.

Incidence and positivity rates rose by 18% and 1.6 percentage points, respectively, against a backdrop of increased testing. The 30–39 age group recorded the highest incidence rate and the sharpest increase. Over the seven-day rolling period from June 19 to 25, the effective R value of 1.16 (95% CI [1.12–1.20]), which was significantly greater than 1, was consistent with ongoing viral circulation in the archipelago. Furthermore, this acceleration in SARS-CoV-2 circulation occurs against a backdrop of increasing prevalence of the L452R mutation (C1 screening result), which is present in several Omicron sublineages (BA.4, BA.5, BA.2.11); specifically, 69% in S25 versus 39% in S24.

In terms of hospital care, visits to emergency departments for suspected COVID-19 increased, while hospitalizations across all departments remained relatively stable.
