On 10 March 6 people are confirmed positive in the commune of Biéville-Beuville in Calvados, making appear in the commune the first cluster in Normandy, which leads the prefect of Calvados, Philippe Court, to prohibit rallies of more than 50 people and to order the closure of establishments welcoming the public.^[17][18]

Stabilization of the epidemic

During the first step of the lifting of the lockdown ( 11 May to 2 June), epidemic indicators continue to decline. Thus, the number of hospitalizations increased from 533^[30] on11 May to 330 on 2 June.^[31] The immunity rate in Normandy (2.6%) remains lower than that of other French regions, but the reproductive index (R0) remains lower than 1, allowing the region to continue the lifting.

These indicators continue to decline during the whole month of June, but 4 clusters of positive cases in south of Rouen causes an increased vigilance of the ARS.^[32]

Sustained growth of positive cases

On 4 August 2020, the ARS observed a 20% increase in the virus's reproductive rate, where the R0 went from 0.98 on 28 July^[33] to 1.19,^[34] confirming the upward dynamics of epidemic indicators with a R0 at 1.44. The latter exceeds the alert threshold on 28 August with a rate of 1.51 as well as the incidence rate (11.05 per 100,000 inhabitant).^[35]

Second lockdown

On 28 October 2020, a second lockdown is announced by Emmanuel Macron.

In the face of the outbreak in Normandy (the incidence rate rising from 11.05/100,000 inhabitants on 28 August to 269.53/100,000 inhabitants on 27 October,^[36] and the tension on hospital beds (38.09% occupancy of beds in intensive care), the ARS triggers the White Plan.^[37]

The peak of the epidemic in Normandy is reached in week 44 of 2020 with a weekly incidence rate of 352 per 100,000 inhabitants and 11,644 new positive tests.^[38]

In the following weeks, the decline of epidemic indicators shows a slowdown of the outbreak. As of 22 November, the incidence rate is 132.8 per 100,000 inhabitants and 4,482 new positive tests.^[39]

On 24 November, French President announced the start of progressive lifting of the lockdown.

Slow and continuous indicator growth

During week 50 (7 to 13 December 2020), epidemic indicators are rising again.^[40] This increase continues until week 2 of 2021, with an incidence rate of 177.5 per 100,000 inhabitants compared to 88.7 in week 50 and a reproduction rate of 1.25, above the alert threshold.^[41]

Vaccination in Normandy begins on 4 January 2021 with the first doses injected at the Rouen University Hospital on voluntary health personnel.^[42]

On 26 January 2021, the ARS announces a first detected case of the British variant in Calvados, leading to a strengthening of screening measures at the local level.^[43]
