The incidence rate falls below the threshold of 1,000 cases per 100,000 inhabitants

For the week of April 30 to May 6, 2022 in Reunion, the number of weekly cases stood at 7,865 against 10,931 the previous week, corresponding to an incidence rate of 919 against 1,277 last week, i.e. a down 28%. The positivity rate is also down to 33.3% (from 36.4% previously). The decrease in viral circulation is confirmed at the start of the new reference week.

Vigilance and respect for barrier gestures remain essential, however, as the virus continues to cause hospitalizations and deaths. Thus, as of May 10, 9 intensive care beds were occupied by Covid patients and 51 by patients with other pathologies (i.e. 81.1% occupancy rate).

Over the past 7 days, 6 deaths linked to Covid-19 are to be deplored.

4 people were not vaccinated or had an incomplete vaccination schedule. The other 2 people were vaccinated, but had strong comorbidities.

The vaccination effort must also be amplified, in particular with the second booster dose in people over 60 years of age. Since April 7, for people aged 60 to 79, the 2nd booster dose is indeed possible, as early as 6 months after receiving the 1st. To facilitate access to vaccination for all Reunionese, the Vaccinobus will once again visit the various municipalities on the island from May 17.

> Health situation

The prefecture and the Regional Health Agency regret to announce this Tuesday, May 10, 2022 the deaths of 6 people who have occurred in the last 6 days:

– 2 people aged 45 to 54,

– 3 people aged 55 to 64,

– 1 person aged over 75.

4 people were not vaccinated or had an incomplete vaccination schedule. The 2 vaccinated persons had comorbidities.

> Positivity rate

The positivity rate is at 33.3% for the week of April 30 to May 6, down from last week.

> Incidence rate

The weekly incidence rate fell sharply, falling below 1,000 to settle at 919/100,000 inhabitants (compared to 1,277 the previous week).

7,865 cases were confirmed from April 30 to May 6.

Given the 395,430 recoveries and 762 deaths since the start of the health crisis,
9,788 cases are still active to date.

405,980 cases have been investigated to date by the ARS, Public Health France and Health Insurance since the start of the epidemic.

> Screening:

31,064 tests were carried out over the period, a drop of nearly 22% compared to the previous week.

Search for Covid-19 mutations

From April 29 to May 6, 4,084 positive cases were screened to identify a mutation: 3,958 cases presented one of the specific mutations under surveillance, in this case the Omicron variant, i.e. 97%.

Confirmed presence of the BA.4 and BA.5 sub-lineage of the Omicron variant in La Réunion by sequencing:

– 2 cases of BA.4 sub-lineage were sequenced in 2 people returning from South Africa at the end of April;

– 1 case of BA.5 sub-lineage was sequenced in 1 person returning from Mauritius at the end of April.

Since the beginning of April, enhanced surveillance has been initiated in conjunction with Santé Publique France on the BA.4 and BA.5 sub-lines. The observations made in South Africa cannot necessarily be transposed to France and Reunion, given the different vaccination coverage and different circulation histories (BA.2 circulated widely in Reunion but little circulated in South Africa ). The joint ARS-Assurance Maladie platform carried out contact tracing with the people concerned in order to limit the risk of transmission of these sub-lineages.

At this stage, no worrying clinical element is associated with these sub-lineages with regard to their predominant circulation in South Africa.

> Hospital situation:

As of May 10, 2022, 9 intensive care beds were occupied by patients positive for Covid-19, out of the 74 beds installed in Reunion, and 51 by patients with other pathologies (81.1% occupancy rate ).
