  • The positivity rate in Nouvelle-Aquitaine went from 1.9% to 4% during the last week of 2020.

  • This is partly a return to normal screening practices, after a sharp increase just before Christmas, decrypts Public Health, but also a resumption of the circulation of the virus.

  • The increase in the positivity rate is observed in all the departments of Nouvelle-Aquitaine.

The situation is partly explained by a return to normal in screening practices.

But also by a resumption of the circulation of the virus.

If there is no need to panic yet, the latest figures from Public Health are hardly reassuring.

According to the latest epidemiological report published this Friday, most of the indicators concerning the circulation of Covid-19 are on the rise in New Aquitaine.

With 5,615 cases confirmed between December 28 and January 3, the positivity rate in the region is now 4%.

It was 1.9% a week earlier, between December 21 and 27.

“This increase is observed in all age groups, particularly among children aged 0 to 14, where the rate has risen from 2.1% to 7.4%, and is thus above the threshold of attention (5%), Public Health note.

At the same time, the screening rate fell sharply in week 53 with 2,321 tests performed per 100,000 inhabitants against 3,650 per 100,000 in week 52, i.e. a drop in the screening rate of 37%.

"

3.8% positivity rate in Gironde

The increase in the positivity rate can be observed in all the departments, particularly in Haute-Vienne (4.6%), Gironde (3.8%), Vienne (3.1%), Landes ( 5.9%) and in Dordogne (3.4%) where this rate has more than doubled.

The departments of Deux-Sèvres and Landes have the highest departmental positivity rates in the region (over 5%).

The incidence rate is also on the rise, since it now stands at 93.6 / 100,000 inhabitants, against 70.5 on December 27, an increase of 30%.

“This trend is observed in all age groups, except for those aged 75 and over, where this rate was already the highest but has remained stable.

“It is 94.7 in Gironde, against 68.8 a week earlier.

This situation is indeed the consequence of "a resumption of the circulation of SARS-CoV-2 in the region", but Public Health also notes that "this evolution of the positivity rate and the screening rate in the opposite direction is probably linked to a "return to normal" in screening practices ".

Stable activity in hospitals

Indeed, during the holidays, “an influx of people wishing to be tested so as not to risk exposing their family circle to the virus has led to an increase in screening as a precaution in asymptomatic people and thus a mechanical decrease in the positivity rate.

We are now witnessing the opposite phenomenon, with a decrease in the number of tests carried out and an increase in the positivity rate linked to a refocusing of screening on symptomatic people and contact cases of confirmed cases.

"

For the moment, activity in hospitals is stable, with 1,140 people hospitalized for Covid-19, including 141 in intensive care.

Among hospitalized patients, more than three-quarters (77.4%) are over 70 years old.

A third of patients (35.3%) are hospitalized in Gironde, 14.5% in Pyrénées-Atlantiques and 10.7% in Landes.
