Improving prediction of future Mycoplasma pneumoniae epidemics using data-driven transmission models

Xu-Sheng Zhang, Xu‐Sheng Zhang, Semjon Sidorov, Ursula Dalrymple et autres

Following the global re-emergence of Mycoplasma pneumoniae infections in 2023–24 after the COVID-19 pandemic,1 a key question is when, and to what extent, these infections will surge in the near future. This question is particularly relevant because the most recent epidemic placed …

Global spatiotemporal dynamics of Mycoplasma pneumoniae re-emergence after COVID-19 pandemic restrictions: an epidemiological and transmission modelling study

Patrick M. Meyer Sauteur, Xu‐Sheng Zhang, Hanne‐Dorthe Emborg, Semjon Sidorov et autres

BACKGROUND: Mycoplasma pneumoniae is a major cause of respiratory tract infections. We aimed to investigate the spatiotemporal dynamics, antimicrobial resistance, and severity of the delayed re-emergence of infections with M pneumoniae after the implementation of non-pharmaceutical interventions (NPIs) against COVID-19. METHODS: Epidemiological …

The frequency of SARS-CoV-2 in stool: A prospective study of healthy preschool children in Sweden

Anna Heydecke, Susanne Sütterlin, Åsa Melhus, Karolina Gullsby

The study investigated the frequency of SARS-CoV-2 among healthy preschool children in two Swedish municipalities, a country where preschools remained uniquely opened throughout the pandemic. Stool samples were obtained from diapers collected at preschools in November-December 2021 and analyzed for SARS-CoV-2 using …

Mycoplasma pneumoniae: delayed re-emergence after COVID-19 pandemic restrictions

Patrick M. Meyer Sauteur, Michael L. Beeton, Sabine Pereyre, Cécile Marie Bébéar et autres

Mycoplasma pneumoniae is a common cause of respiratory tract infections with community-acquired pneumonia as the major disease-related burden. Compared with other pathogens, M pneumoniae is atypical in many ways: it is one of the smallest self-replicating organisms, has a reduced and highly …

Mycoplasma pneumoniae: gone forever?

Patrick M. Meyer Sauteur, Michael L. Beeton, Sabine Pereyre, Cécile Marie Bébéar et autres

Mycoplasma pneumoniae was a common cause of respiratory tract infections before the COVID-19 pandemic, with worldwide incidence of 8·61% from 2017 to 2020, measured by direct test methods.1 However, non-pharmaceutical interventions (NPIs) against COVID-19 drastically lowered the transmission of M pneumoniae. In …

Global spatial dynamics and vaccine-induced fitness changes of Bordetella pertussis

Noémie Lefrancq, Valérie Bouchez, Nadia J. Fernandes, Alex‐Mikael Barkoff et autres

As with other pathogens, competitive interactions between Bordetella pertussis strains drive infection risk. Vaccines are thought to perturb strain diversity through shifts in immune pressures; however, this has rarely been measured because of inadequate data and analytical tools. We used 3344 sequences …
