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.

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.

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.

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

Key numbers about the biology of the SARS-CoV-2 virus and the infection of a single human host by the virus have been compiled from the peer-reviewed literature.

The pattern of past Ebola outbreaks is indicative of an effective reproductive ratio of less than 1, which can lead to the generation of a range of outbreak sizes consistent with the scale of the ongoing epidemic.

The great pond snail is a multipurpose model organism and a contemporary choice for addressing a wide range of biological questions, problems and phenomena in the laboratory and the field.

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.

Oocyte maturation and ovulation in the sister group of vertebrates, Ciona intestinalis Type A, are triggered by Ci-VP, the Ciona homolog of a typical neruopeptide, vasopressin.

Secretory cells in the fruit fly reproductive tract produce secretions that control ovulation through a conserved mechanism that could provide insights into ovarian cancer.
