We investigate how parasites adapt to environmental changes in the context of changing transmission patterns, for example by increasing investment in transmission stages at low endemicity such as elimination settings.

An experimental animal model provides further insights into the host and viral mechanisms underlying airborne transmission of SARS-CoV-2.

Nosocomial transmission of SARS-Cov-2 in geriatric settings is complex, with different patterns between patients and healthcare workers working in Covid/non-Covid wards that should be taken into account when designing infection control strategies.

An important rice reovirus hijacks exosomes to traverse the apical plasmalemma into saliva-stored cavities in the salivary glands of insect vectors, facilitating viral horizontal transmission into rice phloem.

Accounting for nonlinear responses to temperature is critical for accurately predicting how Ross River virus and other mosquito-borne diseases will respond to climate change and detecting the effects of temperature on 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.

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

Multiple steps of the atypical cell cycles underlying Plasmodium gametogony are controlled by a divergent cyclin/cyclin-dependent complex.

Analysis of epidemiological data reveals that viral loads in newly HIV-1 infected individuals in Uganda have declined for two decades, and evolutionary modelling shows that attenuation of the virus explains this decline.

Retroviruses exploit the lectin, Siglec-1/CD169, expressed on sentinel macrophages to promote infection during multiple routes of transmission.
