Public health officials are reporting a concerning rise in several types of bacterial infections across France, including those that can cause meningitis. The increase, based on data from the national Epibac network, highlights the evolving landscape of infectious diseases and underscores the importance of continued surveillance and preventative measures.
Increases in Bacterial Infection Rates
National data reveals significant increases in the incidence of infections caused by Haemophilus influenzae, Streptococcus pneumoniae, and Neisseria meningitidis – all spread through respiratory droplets. These findings signal a potential shift in infection patterns that public health experts are closely monitoring.
- Haemophilus influenzae infections have reached their highest recorded level since surveillance began, with an incidence of 2.31 per 100,000 people, a 19% increase compared to 2023. This rise is particularly pronounced among infants under one year old (+34%) and adults over 90 (+27%).
- The incidence of Streptococcus pneumoniae has climbed to 10.25 per 100,000 people, representing a 14% increase year-over-year. This bacterium accounts for the majority of invasive infections, with an estimated 6,857 cases, including 6,059 cases of bacteremia and 798 cases of meningitis. The highest rates are observed in individuals over 85 years of age.
- Neisseria meningitidis infections have reached 0.94 per 100,000 people (+9%), exceeding levels seen before the COVID-19 pandemic. Infants, young adults aged 15-24, and those over 85 are experiencing the highest rates.
- While Streptococcus pyogenes infections have decreased to 4.50 per 100,000 (-27%) after an exceptionally high level in 2023, rates remain higher than those observed before 2022.
- Listeria monocytogenes continues to show an upward trend, with an incidence of 0.99 per 100,000, an 8% increase from 2023.
- Streptococcus agalactiae infections have slightly decreased to 4.80 per 100,000, but remain the leading cause of invasive infection in infants under one year old, with an incidence of 44.9 per 100,000 in this age group.
Regional Variations in Overseas Territories
Significant differences in infection rates are being observed in France’s overseas departments and regions (DROM).
- Mayotte is experiencing the highest incidence rates of Streptococcus pyogenes.
- Martinique and Guadeloupe are reporting the highest levels of Streptococcus agalactiae.
- Guyane is recording the highest rates of Streptococcus pneumoniae.
Overall, infections caused by Streptococcus agalactiae are more common across the DROM compared to mainland France. These regional variations highlight the need for tailored public health strategies to address local infection patterns.
