Gastroenteritis

COVID-19

• COVID-19 viral circulation in the BFC region is increasing for the 9th consecutive week (TI=556/100,000 inhabitants, up 14%; TP=8.0%, up 2%), mirroring the trend observed nationwide. The weekly number of people testing positive for COVID-19 continues to rise, reaching 15,462 cases in Week 49 (+1,949 cases compared to Week 48-2021, or +14%).

• All age groups are affected by this upward trend in indicators, particularly those under 15 and those of childbearing age: the under-15 age group has the highest incidence rate (890 per 100,000 inhabitants, +14%) and the highest testing activity; the 25–44 age group also has a high incidence rate (773 per 100,000 population, +20%) and a high testing rate (7,966 per 100,000 population, +13%). With a testing rate that has increased relatively little over the past 5 weeks (unlike other age groups), the rise in incidence is less pronounced among those aged 65 and older (265 per 100,000 population, +4%). The highest positivity rate is found among those aged 25–44 (9.7%) and those aged 45–64 (9.3%).

• SARS-CoV-2 is still actively circulating throughout the region, particularly in the eastern part of the region. Doubs (720/100,000 inhabitants), Jura (695/100,000 inhabitants), and Saône-et-Loire (588/100,000 inhabitants) have the highest incidence rates. The sharpest increases in incidence rates are observed in Yonne (+29%), Côte-d’Or (+21%), and Haute-Saône (+21%). In all departments, the incidence rates reached this summer have been exceeded, as have the incidence thresholds reached at the peak of the third wave (early April 2021), with the exception of Nièvre.
