    Reconstruction of transmission chains of SARS-CoV-2 amidst multiple outbreaks in a geriatric acute-care hospital: a combined retrospective epidemiological and genomic study

    Mohamed Abbas, Anne Cori ... Stephan Harbarth
    Nosocomial transmission of SARS-Cov-2 in geriatric settings is complex, with different patterns between patients and healthcare workers working in Covid/non-Covid wards that should be taken into account when designing infection control strategies.

    Deep-sequence phylogenetics to quantify patterns of HIV transmission in the context of a universal testing and treatment trial – BCPP/Ya Tsie trial

    Lerato E Magosi, Yinfeng Zhang ... Marc Lipsitch
    HIV transmissions into intervention communities from control communities in the Botswana/Ya Tsie trial were similar to the reverse at baseline, and 10 times more common post-baseline, concordant with a predicted benefit of a universal test-and-treat HIV prevention intervention.

    Plasmodium falciparum adapts its investment into replication versus transmission according to the host environment

    Abdirahman I Abdi, Fiona Achcar ... Matthias Marti
    We investigate how parasites adapt to environmental changes in the context of changing transmission patterns, for example by increasing investment in transmission stages at low endemicity such as elimination settings.

    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.

    Exosomes mediate horizontal transmission of viral pathogens from insect vectors to plant phloem

    Qian Chen, Yuyan Liu ... Taiyun Wei
    An important rice reovirus hijacks exosomes to traverse the apical plasmalemma into saliva-stored cavities in the salivary glands of insect vectors, facilitating viral horizontal transmission into rice phloem.

    Quantifying the impact of quarantine duration on COVID-19 transmission

    Peter Ashcroft, Sonja Lehtinen ... Sebastian Bonhoeffer
    Test-and-release quarantine strategies for traced contacts of confirmed SARS-CoV-2 cases and returning travellers can reduce average quarantine durations while remaining as effective as 10 days of quarantine without testing.

    Temperature explains broad patterns of Ross River virus transmission

    Marta Strecker Shocket, Sadie J Ryan, Erin A Mordecai
    Accounting for nonlinear responses to temperature is critical for accurately predicting how Ross River virus and other mosquito-borne diseases will respond to climate change and detecting the effects of temperature on disease transmission.

    COVID-19 cluster size and transmission rates in schools from crowdsourced case reports

    Paul Tupper, Shraddha Pai ... Caroline Colijn
    Fitting a simple model of COVID-19 transmission to crowdsourced case report data allowed the estimation of mean cluster size and transmission rates in Canadian schools, as well as determining which interventions are most likely to limit transmission.

    Evidence for transmission of COVID-19 prior to symptom onset

    Lauren C Tindale, Jessica E Stockdale ... Caroline Colijn
    Control of COVID-19 will require strong case finding and isolation of exposed individuals because transmission can occur days prior to symptom onset.

    A divergent cyclin/cyclin-dependent kinase complex controls the atypical replication of a malaria parasite during gametogony and transmission

    Aurélia C Balestra, Mohammad Zeeshan ... Mathieu Brochet
    Multiple steps of the atypical cell cycles underlying Plasmodium gametogony are controlled by a divergent cyclin/cyclin-dependent complex.
