    Evidence for transmission of COVID-19 prior to symptom onset

    Lauren C Tindale et al.
    Control of COVID-19 will require strong case finding and isolation of exposed individuals because transmission can occur days prior to symptom onset.

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

    Qian Chen et al.
    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.

    In vivo imaging of retrovirus infection reveals a role for Siglec-1/CD169 in multiple routes of transmission

    Kelsey A Haugh et al.
    Retroviruses exploit the lectin, Siglec-1/CD169, expressed on sentinel macrophages to promote infection during multiple routes of transmission.

    A transmission-virulence evolutionary trade-off explains attenuation of HIV-1 in Uganda

    François Blanquart et al.
    Analysis of epidemiological data reveals that viral loads in newly HIV-1 infected individuals in Uganda have declined for two decades, and evolutionary modelling shows that attenuation of the virus explains this decline.

    Temperature explains broad patterns of Ross River virus transmission

    Marta Strecker Shocket et al.
    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.

    Quantifying the impact of quarantine duration on COVID-19 transmission

    Peter Ashcroft et al.
    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.

    Transmission of West Nile and five other temperate mosquito-borne viruses peaks at temperatures between 23°C and 26°C

    Marta S Shocket et al.
    Mechanistic, trait-based models for transmission of West Nile virus and observed incidence of human West Nile disease cases in the US both show optimal transmission at 24-25°C.

    Synergy in anti-malarial pre-erythrocytic and transmission-blocking antibodies is achieved by reducing parasite density

    Ellie Sherrard-Smith et al.
    Combining pre-erythrocytic and transmission blocking antibodies enhances the overall control and potential elimination of malaria within both mosquito and vertebrate populations.

    Mapping residual transmission for malaria elimination

    Robert C Reiner Jr et al.
    A fine-grain map of residual transmission and importation in Swaziland shows where to target malaria elimination efforts.

    Mapping influenza transmission in the ferret model to transmission in humans

    Michael G Buhnerkempe et al.
    Influenza transmission among ferrets correlates strongly with transmission among humans, so the ferret model for influenza transmission is a valid tool for pandemic potential in humans.
