    COVID-19 pandemic dynamics in South Africa and epidemiological characteristics of three variants of concern (Beta, Delta, and Omicron)

    Wan Yang, Jeffrey L Shaman
    Model-inference reconstructed SARS-CoV-2 transmission dynamics in South Africa during March 2020 to February 2022, and quantified the immune erosion potential and transmissibility of three major variants (Beta, Delta, and Omicron), highlighting their common characteristics and the need for more proactive preparedness.

    Re-visiting the trans insertion model for complexin clamping

    Shyam S Krishnakumar, Feng Li ... Karin M Reinisch
    Biochemical experiments provide support for the trans insertion model for clamping in the regulation of neurotransmitter release by complexin.

    Host and viral determinants of airborne transmission of SARS-CoV-2 in the Syrian hamster

    Julia R Port, Dylan H Morris ... Vincent J Munster
    An experimental animal model provides further insights into the host and viral mechanisms underlying airborne transmission of SARS-CoV-2.

    Integrating between-host transmission and within-host immunity to analyze the impact of varicella vaccination on zoster

    Benson Ogunjimi, Lander Willem ... Niel Hens
    An individual-based model estimates exogenous boosting of immunity following re-exposure to chickenpox is limited to 2 years after re-exposure, but an increase in herpes zoster incidence is still expected to occur following universal varicella vaccination.

    How competition governs whether moderate or aggressive treatment minimizes antibiotic resistance

    Caroline Colijn, Ted Cohen
    Both within and between hosts, the key factor guiding whether increasing treatment strength will increase or decrease antibiotic resistance is whether inter-strain competition is effective, not whether it is present.

    Pathogen invasion-dependent tissue reservoirs and plasmid-encoded antibiotic degradation boost plasmid spread in the gut

    Erik Bakkeren, Joana Anuschka Herter ... Wolf-Dietrich Hardt
    Bacterial gut pathogens that invade into host tissues during infection can boost the spread and accumulation of plasmids over time by forming reservoirs containing these plasmids within host tissues.

    Elevation of CpG frequencies in influenza A genome attenuates pathogenicity but enhances host response to infection

    Eleanor Gaunt, Helen M Wise ... Peter Simmonds
    Mutants of influenza A virus with increased CpG dinucleotide frequencies show restricted replication and reduced or absent pathogenicity, and powerful host innate and adaptive responses to infection that confer immunity to re-infection.

    Single-cell expression profiling reveals dynamic flux of cardiac stromal, vascular and immune cells in health and injury

    Nona Farbehi, Ralph Patrick ... Richard P Harvey
    Comprehensive scRNA-seq analysis of cardiac stromal cells in healthy and injured hearts reveals novel cell types and non-linear cell dynamics, providing new insights into cardiac inflammation, fibrosis and repair.

    Epidemiological and ecological determinants of Zika virus transmission in an urban setting

    José Lourenço, Maricelia Maia de Lima ... Mario Recker
    An ento-epidemiological model reveals that what made the Zika virus a public health problem in Feira de Santana, Brazil, was a surprisingly high attack rate coupled with a low risk of Microcephaly per challenged pregnancy.

    Phylodynamic theory of persistence, extinction and speciation of rapidly adapting pathogens

    Le Yan, Richard A Neher, Boris I Shraiman
    A model of pathogen co-evolving with host population continuously acquiring immunity is used to identify evolutionary parameters allowing pathogen population to persist without going extinct or splitting into independent lineages.
