Background: Yearly bronchiolitis and influenza-like illness epidemics in France often involve high morbidity and mortality, which severely impacts healthcare. Epidemics are declared by the French National Institute of Public Health based on syndromic surveillance of primary care and emergency departments (ED), using statistics-based alarms. Although the effective reproduction number (Rt) is used to monitor the dynamics of epidemics, it has never been used as an early warning tool for bronchiolitis or influenza-like illness epidemics in France.

- During 5,300 to 4,900 cal BP, much of Europe experienced a population decline known as the Neolithic decline, with debated causes including agricultural crisis and early plague spread.
- Researchers analyzed ancient genomes from 108 Scandinavian Neolithic individuals and found evidence of widespread plague infections in at least 17% of the population, occurring through three distinct events over roughly 120 years.
- The study also reconstructed family lineages indicating a patrilineal social structure and noted examples of female exogamy, contributing to a clearer understanding of the social dynamics and disease impact during this period.
