Key Points

• Viral circulation is declining in Hauts-de-France, but virological indicators remain at high levels among adults (incidence rate ≈500 cases/100,000 inhabitants).

• Among those aged 65 and older, the rise in ILI and respiratory illness rates continues in the departments of Somme and Aisne.

• In urban areas, consultations for acute respiratory infections (all causes combined) continue to rise among doctors in the Sentinelles Network.

• In hospitals, the number of emergency room visits is now stable at the regional level, although it continues to rise in the Pas-de-Calais department. In critical care, the number of new admissions is rising at the regional level, particularly in the Nord department.

• The number of outbreaks in long-term care facilities and the number of cases among residents have been rising since week 49.

• Currently, the proportion of people aged 60 to 79 and those over 80 who have “up-to-date” vaccination protection against COVID-19 or protection adapted to the Omicron variants remains insufficient.
