Reporting of sexually transmitted infections during the COVID-19 pandemic

Sexually Transmitted Infections, 2020
Social distancing guidelines and resource reallocation during the COVID-19 pandemic have led to significant disruption of sexual health clinics within the USA.1 Little is known about how this disruption has impacted STI reporting.

On the Universality of Jordan Centers for Estimating Infection Sources in Tree Networks [PDF]

, 2014
Finding the infection sources in a network when we only know the network topology and infected nodes, but not the rates of infection, is a challenging combinatorial problem, and it is even more difficult in practice where the underlying infection spreading model is usually unknown a priori. In this paper, we are interested in finding a source estimator

Working with Miraculous Mice: Mus musculus as a Model Organism

Current Protocols, Volume 4, Issue 10, October 2024.
Abstract The laboratory mouse has been described as a “miracle” model organism, providing a window by which we may gain an understanding of ourselves. Since the first recorded mouse experiment in 1664, the mouse has become the most used animal model in biomedical research.

Significance of serology testing to assist timely diagnosis of SARS-CoV-2 infections: implication from a family cluster

Emerging Microbes and Infections, 2020
Confirmative diagnosis of SARS-CoV-2 infections has been challenged due to unsatisfactory positive rate of molecular assays. Here we identified a family cluster of SARS-CoV-2 infections, with five of six family members were SARS-CoV-2-specific ...

Spatially dense stochastic epidemic models with infection-age dependent infectivity [PDF]

arXiv, 2023
We study an individual-based stochastic spatial epidemic model where the number of locations and the number of individuals at each location both grow to infinity. Each individual is associated with a random infection-age dependent infectivity function. Individuals are infected through interactions across the locations with heterogeneous effects.

Serological differentiation between COVID-19 and SARS infections

Emerging Microbes and Infections, 2020
In response to the coronavirus disease 2019 (COVID-19) outbreak, caused by SARS-CoV-2, multiple diagnostic tests are required for acute disease diagnosis, contact tracing, monitoring asymptomatic infection rates and assessing herd immunity.

A re-entrant phase transition in the survival of secondary infections on networks [PDF]

, 2018
We study the dynamics of secondary infections on networks, in which only the individuals currently carrying a certain primary infection are susceptible to the secondary infection. In the limit of large sparse networks, the model is mapped to a branching process spreading in a random time-sensitive environment, determined by the dynamics of the ...

Rapid taxonomic categorization of short, abundant virus sequences for ecological analyses

Ecology and Evolution, Volume 14, Issue 6, June 2024.
We sampled 1086 bats from two, adjacent Puerto Rican caves and tested them for infection by herpesviruses, resulting in 3131 short, viral sequences. Using percent identity of nucleotides and a machine learning algorithm (affinity propagation), we categorized herpesviruses into 43 operational taxonomic units (OTUs).

Limited availability of methods for the detection of xenotransplantation‐relevant viruses in veterinary laboratories

Xenotransplantation, Volume 31, Issue 3, May/June 2024.
Abstract Background The German Xenotransplantation Consortium is in the process to prepare a clinical trial application (CTA) on xenotransplantation of genetically modified pig hearts. In the CTA documents to the central and national regulatory authorities, that is, the European Medicines Agency (EMA) and the Paul Ehrlich Institute (PEI), respectively,
