Abstract An increase in pneumonia-related emergency department visits was observed in Lombardy, northern Italy, during June–October 2024. Viral causes appear insufficient to explain the increase, suggesting a bacterial cause . Mycoplasma pneumoniae and Bordetella pertussis emerged as possible causes when other surveillance systems were consulted, but the reasons behind this trend remain unknown .

Summary Background An epidemic of Mycoplasma pneumoniae infection has been observed in France since September, 2023. We aimed to describe the characteristics of adults hospitalised for M pneumoniae infection and identify factors associated with severe outcomes of infection. Methods MYCADO is a retrospective observational study including adults hospitalised for 24 h or more in 76 hospitals in France for a M pneumoniae infection between Sept 1, 2023, and Feb 29, 2024. Clinical, laboratory, and imaging data were collected from medical records. We identified factors associated with severe outcomes of infection, defined as a composite of intensive care unit (ICU) admission or in-hospital death, using multivariable logistic regression. Findings 1309 patients with M pneumoniae infection were included : 718 (54·9%) were men and 591 (45·1%) were women; median age was 43 years (IQR 31–63); 288 (22·0%) had chronic respiratory failure; 423 (32·3%) had cardiovascular comorbidities; and 105 (8·0%) h...

{Excerpt} In the 52nd week of 2024 ( December 23rd to December 29th ), respiratory samples from outpatient influenza-like cases and hospitalized severe acute respiratory infection cases collected in sentinel hospitals across the country (excluding Hong Kong, Macao and Taiwan) were tested for 10 viruses including the new coronavirus, influenza virus, respiratory syncytial virus, adenovirus, human metapneumovirus, parainfluenza virus, common coronavirus, bocavirus, rhinovirus and enterovirus , as well as multiple respiratory pathogens including Mycoplasma pneumoniae. 1. Test results The pathogens detected positive in respiratory samples of influenza-like cases in outpatient and emergency departments of sentinel hospitals were mainly influenza virus, human metapneumovirus, and rhinovirus ; the pathogens detected positive in respiratory samples of hospitalized severe acute respiratory infection cases were mainly influenza virus, Mycoplasma pneumoniae, and human metapneumovirus . The specif...
