Contamination is on the rise again in Europe

And it’s gone again. The resurgence of the Europe-wide Covid-19 epidemic was predictable, but everyone preferred to look elsewhere. In one week, the number of new cases in France jumped by almost 50%, with 45,700 new infections per day over the period from 12 to 18 June (they were 365,000 at the height of the epidemic in France). to me). -January).

Relaxation of barriers in business, public transport, public holidays and leisure…; low adherence to the second booster dose among eligible populations (ie, in France, people with comorbidities and those over 60 who had a first booster more than six months ago); weakening, too, over the months, the protection afforded by three doses of vaccine… The virus exploits these flaws to its advantage to sneak in and thrive there.

Especially since the latest representatives of the Omicron variant – BA.4 and BA.5 – have acquired evolutionary advantages: an increased contagiousness, compared to their predecessor BA.2 (which itself already reached record levels of transmissibility) ; and a new escape from the defenses acquired by vaccination or the previous variants – or even by Omicron itself in its first version, BA.1.

Results: In all European countries, the picture is similar. A resurgence of cases, mainly due to the spread of the sub-variants BA.4 and especially BA.5. Without, for the time being, this resurgence of naked infections translates into a marked increase in hospital admissions and deaths, but a slight increase. Only Portugal is an exception: affected earlier by the wave, he already sees it, after two months, begin to recede.

On Tuesday, June 21, the incidence rate reached 477 cases per 100,000 inhabitants, up 49% from the previous week, according to the latest data from Public Health France (SpF). This recovery, which began in early June, is observed in all metropolitan areas and for almost all age groups. One infected person contaminates another 1.39 on average.

Sub-variant BA.5 is now responsible for more than half of new contamination. From June 12 to 18, 45,697 new cases a day were confirmed, according to the SI-Dep contamination database. The screening rate was 1,993.6 per 100,000 inhabitants (+ 6.2% compared to the previous week), and the positivity rate was 23.9% (+ 4.2 points).
