Transmission trees describe who infected whom during outbreaks of infectious diseases (see example tree below). These data are routinely collected through resource intensive methods including…

Schistosomiasis is a parasitic disease that impairs the physical and cognitive development of more than 200 million individuals globally, as a result of physiological disruptions…

Second order statistics such as variance and autocorrelation can in principle provide early warning of disease (re-)emergence. Such statistics can detect the approach to an…

The prevalence of a pathogen emerging in a population varies in a complex manner that is difficult to model and predict, due in part to…

Effective public health efforts require an accurate understanding of which virus species are capable of spreading between humans or may develop this ability in the…

Host-parasite networks are built from a vast number of interactions, which may change seasonally or based on host densities. This combination of complexity and uncertainty…

Zika is an emerging virus whose rapid spread is of great public health concern. Knowledge about transmission remains incomplete, especially concerning potential transmission in geographic…

Bifurcation delay is a phenomenon that occurs when dynamical systems go through a critical transition. Bifurcation delay occurs because the state of the system may…

The majority of infectious diseases currently emerging in humans originated in mammals. Yet we still know very little about the global patterns of mammal-to-human pathogen transmission….

Preventing future outbreaks of ebolaviruses in humans and other vulnerable animal populations will require identifying the natural reservoirs of filoviruses. Accumulating indirect evidence points to…
