Social connectivity increases an individual’s likelihood of behavioural adoption if the learning rule depends on the extent of social connections to informed others, but is unrelated when learning depends on the ratio of connections to informed versus uninformed others.

Differences in patterns of social contact between settings have consequences for the spread and transmission of respiratory pathogens and the effectiveness of different measures aimed at their control.

Social interactions can have a direct effect on the composition of the gut microbiome in wild primates.

A new way of measuring sociality in human and animal contact networks reveals the link between social behavior, population density, and disease transmission.

Fitting a simple model of COVID-19 transmission to crowdsourced case report data allowed the estimation of mean cluster size and transmission rates in Canadian schools, as well as determining which interventions are most likely to limit transmission.

Analyses combining genomic and epidemiological data of Mycobacterium bovis, which causes bovine tuberculosis, revealed evidence of transmission within and between cattle and badger populations.

Beyond well-recognized individual-level risk factors, HIV and hepatitis C transmission among people who inject drugs are further impacted by social and spatial network composition, and spaces in particular may represent efficient means for disseminating interventions that diffuse through the network.

Neurexins are presynaptic adhesion molecules in the serotonin system which regulate neuron survival and serotonin neuromodulation through active zone formation and serotonin release.

Control of COVID-19 will require strong case finding and isolation of exposed individuals because transmission can occur days prior to symptom onset.

Social networks can be the primary risk factor for mumps infection and transmission, regardless of age and vaccination status.
