Key Points

The COVID-19 outbreak continued to spread in Auvergne-Rhône-Alpes during Week 39 (September 21–27, 2020), though at a slower pace than in recent weeks. In week 39, 9,788 new cases were diagnosed (+10% compared to week 38), while the number of people tested decreased by 12%. The incidence rate (122/100,000) is therefore rising, and notably the positivity rate (8.9%), placing the region above the average rates observed in metropolitan France. The proportion of symptomatic individuals among those tested and confirmed cases increased in week 39. The trend in these indicators is consistent with the testing prioritization strategy implemented in recent weeks. Incidence rates remain very high and are rising sharply among young adults.

COVID-19-related activity in hospitals continues to rise at an alarming rate, even though this increase appears less significant than the previous week (+18% in new hospitalizations and ICU admissions). In week 39, the increase in hospital deaths was significant (+70%). A significant excess mortality from all causes was observed in week 38 at the regional level for the first time since late April. The situation remains concerning in nursing homes, even though the number of reported cases appears to be stabilizing, as the number of active clusters in nursing homes remains high. Clusters in higher education institutions remain numerous.

All indicators show that the departments of Rhône, Loire, and Isère are the hardest hit by the epidemic, while other departments (Allier, Ardèche, Cantal, and Haute-Savoie) appear less affected. The Rhône has the highest incidence rate after Paris, and Isère has the highest positivity rate in metropolitan France. Within a single department, incidence rates can vary significantly between urban and rural areas, as evidenced by the incidence rates across the region’s four metropolitan areas. Behavioral prevention measures are essential. Adherence to protective measures—wearing masks, physical distancing, and hygiene (handwashing)—must be strictly enforced, including by those who are less vulnerable, as they contribute to the spread of the virus to more vulnerable individuals (the elderly, those with comorbidities) who are at the highest risk of complications or severe forms of COVID-19.
