Stochastic models able to reproduce both incidence and seroprevalence data for Zika outbreaks in the Pacific Islands estimate that the basic reproduction number (R₀) is between 1.5 and 4.1.

An analysis of publications and research grants shows that the volume of research on reproductive organs is much less than that on non-reproductive organs.

The human immunodeficiency virus HIV-1 primarily spreads between cells using a method called cell-to-cell infection, suggesting that this process may be a target for anti-viral drugs.

Evidence for a selective sensorimotor brain mechanism responsible for translating sensory numerical information into the number of actions in a sequence.

Heterogeneity in exposure to malaria vectors, including sporozoite-infected mosquitoes, contributes to the variation in human infection risk and amplifies the local transmission potential.

Countrywide agent-based simulations with building-level resolution reveal the importance of demographic repartition and population density on epidemic dynamics of respiratory infections.

Following exposure of Leishmania culture promastigotes to DNA stress, single-cell RNA sequencing reveals discrete clusters of cells associated with efficient generation of hybrids between different species and strains in vitro marked by expression of the ancestral gamete fusogen HAP2.

Nearly 75% of SARS-CoV-2 infections on the Diamond Princess were asymptomatic, half were never detected, and asymptomatic infections may have contributed substantially to transmission.

A method to assess the risk of self-sustained HIV transmission in heterosexuals from phylogenetic and epidemiological data is developed and, when applied to the Swiss HIV epidemic, shows that this risk is negligibly small for Switzerland.

Phylogenetic evidence suggests that the majority of HIV infections occurring in the UNAIDS Fast-track city Amsterdam continue to have an Amsterdam resident as source, indicating that the majority of HIV infections in Amsterdam could be prevented through city-level interventions.
