|Table 1: Weekly Indicators in Week 22 (May 31 to June 6, 2021)|
Global mortality in nails
After several months of high mortality, the number of deaths from all causes has returned to expected values.
Incidence rates are declining rapidly and all areas have fewer than 100/100 000 inhabitants (from -30% to -44%), with a less significant decrease in Corsica, but where incidence rates remain low (21 in S22) Vs 23 and S21).
The highest incidence rates have been observed in the le-de-France (86/100,000 inhabitants) and Hauts-de-France (75) regions. At the departmental level, we see a sharp decrease in the incidence rate in all departments (over -30 per cent in 76 departments) except in Corse-du-Sud, where it was increasing slightly at low levels (29 in S22). Vs 21 and S21).
On the other hand, in some foreign departments, the incidence remains high, especially in Guyana (297/100 000 inhabitants) and Réunion (143/100 000 inhabitants).
Do you know the variants by their short names?
Screening indicators still show a predominance of the proportion of the suspected 20I/501Y.V1 (alpha, emerging in the UK) anxiety type (74.6%). The proportion of suspected 20H/501Y.V2 (beta, emerged in South Africa) or 20J/501Y.V3 (gamma, emerged in Brazil) with departmental disparities at the national level was 6.3%.

In this regard, Public Health France indicates that the investigation of positive tests looking for the three worrying variants VOC 20I/501Y.V1 (Alpha) and indiscriminately VOC 20H/501Y.V2 (Beta) and 20J/501Y.V3 (Gamma) strategy of. ) are gradually being abandoned in favor of a newer screening strategy, in which mutations of interest (E484K, E484Q and L452R) cause their effects on mutations (L452R) or their possible escape from the immune response (E484K, E484Q and L452R). Looking for.
No significant spread of the delta version
Regarding variant B.1.617.2 (Delta, emerged in India) which is already widely spreading in the United Kingdom” To date, nothing indicates a significant prevalence of this lineage on the region. However, the presence of clusters with this type of autochthonous transmission indicates that such transmissions have begun in France and should lead to the greatest caution, avoiding a potential vaccine and its transmission efficiency in comparison. Looking at the data in favor of growth, for the reference type and the 20I / 501Y.V1 version (alpha) » Notifies this epidemiological bulletin.
This delicate balance is yet to be confirmed in the coming weeks…
