    Zika seroprevalence declines and neutralizing antibodies wane in adults following outbreaks in French Polynesia and Fiji

    Alasdair D Henderson et al.
    A combination of eight serological surveys shows a decline in seroprevalence over a two-year period following the first reports of Zika transmission in Fiji and French Polynesia.

    Estimating SARS-CoV-2 seroprevalence and epidemiological parameters with uncertainty from serological surveys

    Daniel B Larremore et al.
    Integrating over multiple forms of statistical uncertainty associated with serological surveys can improve serosurvey design while also enabling that uncertainty to be appropriately propagated through epidemiological models.

    Structure in the variability of the basic reproductive number (R0) for Zika epidemics in the Pacific islands

    Clara Champagne et al.
    Stochastic models able to reproduce both incidence and seroprevalence data for Zika outbreaks in the Pacific Islands estimate that the basic reproduction number (R0) is between 1.5 and 4.1.

    Nationally-representative serostudy of dengue in Bangladesh allows generalizable disease burden estimates

    Henrik Salje et al.
    To maximize broad insight on disease burden, seroprevalence studies should be generalizable to the wider population, both in age and location.

    Opportunities for improved surveillance and control of dengue from age-specific case data

    Isabel Rodriguez-Barraquer et al.
    Age-specific incidence data, combined with mechanistic models of immunity, provides a unique opportunity to characterize disease transmission of dengue and other immunizing diseases at high temporal and spatial resolution.

    Enteropathogen antibody dynamics and force of infection among children in low-resource settings

    Benjamin F Arnold et al.
    Among children in low-resource settings, diverse enteropathogens share common, population-level antibody dynamics, which creates a new opportunity to estimate transmission through serologic surveillance.

    Modeling the impact of racial and ethnic disparities on COVID-19 epidemic dynamics

    Kevin C Ma et al.
    Racial and ethnic disparities in SARS-CoV-2 infection rates can impact overall epidemic dynamics and herd immunity, underscoring the need to develop socially informed transmission models that account for population variability.

    The effect of climate change on yellow fever disease burden in Africa

    Katy AM Gaythorpe et al.
    Analysis of yellow fever burden in Africa illustrates the need to consider the effect of a changing climactic conditions when planning future intervention strategies.

    Efficacy profile of the CYD-TDV dengue vaccine revealed by Bayesian survival analysis of individual-level phase III data

    Daniel J Laydon et al.
    Bayesian survival analysis reveals comprehensive efficacy profile and mechanism of action for Sanofi-Pasteur’s CYD-TDV dengue vaccine, whereby vaccination acts as a silent, disease-free infection enhancing disease risk in seronegatives, but giving greater immunity in seropositives than two natural infections.

    Evidence of human infection by a new mammarenavirus endemic to Southeastern Asia

    Kim R Blasdell et al.
    New mammarenaviruses have been identified from rodents in Cambodia and Thailand, and the Cardamones variant of Wēnzhōu virus has been found in Cambodian patients presenting with fever and respiratory symptoms.
