host and viral traits predict zoonotic spillover from mammals. | the majority of human emerging infectious diseases are zoonotic, with viruses that originate in wild mammals of particular concern (for example, hiv, ebola and sars). understanding patterns of viral diversity in wildlife and determinants of successful cross-species transmission, or spillover, are therefore key goals for pandemic surveillance programs. however, few analytical tools exist to identify which host species are likely to harbour the next human virus, or which viruses can cross species ... | 2017 | 28636590 |
predicting the global mammalian viral sharing network using phylogeography. | understanding interspecific viral transmission is key to understanding viral ecology and evolution, disease spillover into humans, and the consequences of global change. prior studies have uncovered macroecological drivers of viral sharing, but analyses have never attempted to predict viral sharing in a pan-mammalian context. using a conservative modelling framework, we confirm that host phylogenetic similarity and geographic range overlap are strong, nonlinear predictors of viral sharing among ... | 2020 | 32385239 |
una virus: first report of human infection in argentina. | una virus (unav), togaviridae family, is widely distributed in south america, where infections have been detected in mosquitoes and vertebrate hosts (humans, birds and horses). we analyzed human sera from córdoba inhabitants aged 44 to 89 years and using a neutralization test, we found a prevalence of unav antibodies of 3.8% (3/79). the low titers detected suggest past infections probably acquired in rural areas of the province of córdoba (central argentina). none sera were found positive for ma ... | 2003 | 12754579 |
