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.
Pathogen natural history, epidemiological knowledge, human behavior and epidemic progression determine whether symptom screening and questionnaires are effective barriers to geographic spread of infection by travelers.
A multipartite virus functionally spreads its distinct genome segments in distinct individual cells of the host plant, and complementation of the viral genes across cells allows a pluricellular infection cycle.
Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.
Building on previous work (Pigott et al. 2014), estimates of areas of potential transmission of Ebola virus are revised and updated to provide a contemporary map for use by researchers and policymakers.
