The study of the incidence and spread of infectious diseases in populations over time. Host, pathogen and environmental factors are monitored to determine the dynamics of infection, the ultimate goal of which is to devise intervention strategies. Molecular methods, such as phylogenomics, can be used to accurately track pathogens.
In this study, the authors detect diverse Ehrlichia and Anaplasma bacteria in samples from Amazonian wildlife, humans and ticks that are mostly distinct from pathogens detected in the Northern Hemisphere and that might indicate emerging health hazards from tick-borne diseases in the Amazon rainforests.
In this Review, Pai and colleagues examine the global landscape of drug-resistant tuberculosis, exploring its epidemiology, causes, risk factors, stigma and associated mental health burden as well as discussing the most recent developments in diagnostics, treatment and preventive regimens.
This study finds that a deadly skin disease in red squirrels is associated with a staphylococcal clone often acquired through spillover from other hosts.
A recent study reports that anthropogenic land use causes major changes in the diversity and taxonomic composition of reservoir hosts for pathogens, with implications for the emergence of zoonotic diseases.
Epidemiological modelling informs government responses to the COVID-19 pandemic, but confusion abounds about the models. What can physicists do to help?
