Ecological and evolutionary perspectives are critical to understand, predict, prevent, and treat malaria parasites that may spread to humans from our close primate relatives.

While flooding events may drive spillover transmission of Leptospira spp. through dispersal of the bacteria at low elevations, at higher elevations environmental risk is more localised and directly driven by the distribution of local rat reservoir populations.

Predators may amplify multiple-host parasite spreading in systems with multiple transmission routes.

The systematic field testing of excreta from Australian native possums for the bacterial pathogen Mycobacterium ulcerans can be used to build statistical models that predict the regions in southeast Australia where humans will subsequently get Buruli ulcer.

Comparative phylogenomic analyses based on a new reference-quality human Ascaris genome assembly reveals a pig/human interbred species complex with implications for Ascaris control worldwide.

Livestock abortion surveillance can capture valuable information on important livestock pathogens, including those that are zoonotic and with epidemic potential, revealing importance of timely collection of diagnostic samples for attribution.

MERS-CoV infections in the Arabian Peninsula are the result of several hundred spillover events from viruses circulating in camels into the human population.

Genome sequence data from 58 Mexican swine influenza A viruses resolves the spatial origin of the virus that originated the influenza pandemic of 2009.

The success of angiotensin-converting enzyme 2 (ACE2)-based predictions of severe acute respiratory syndrome-associated virus 2 (SARS-CoV-2) host range stems from phylogenetic correlation, allowing development of scalable models which predict susceptibility to SARS-CoV-2 and other sarbecoviruses without requiring additional ACE2 sequencing.

Understanding where future Ebola virus outbreaks may start and the changing nature of the populations living in these places is of critical importance in helping to prepare for future outbreaks.
