Measurement of Plasmodium falciparum transmission intensity using serological cohort data from Indonesian schoolchildren. [PDF]

open access: yes, 2013
BACKGROUND: As malaria transmission intensity approaches zero, measuring it becomes progressively more difficult and inefficient because parasite-positive individuals are hard to detect. This situation may arise shortly before achieving local elimination,

Comparing specificity and seroconversion sensitivity among major blood screening assays for human immunodeficiency virus and viral hepatitis

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives Accurate detection of transfusion‐transmissible infections, such as human immunodeficiency virus (HIV) and hepatitis C and B viruses (HCV/HBV), is critical to ensure blood safety, and screening assays must demonstrate high specificity and sensitivity.

Viral antibody dynamics in a chiropteran host [PDF]

open access: yes, 2014
1. Bats host many viruses that are significant for human and domestic animal health, but the dynamics of these infections in their natural reservoir hosts remain poorly elucidated.<p></p> 2.

Bayesian Estimation of True Prevalence and Associated Risk Factors for Leptospira spp. Among Slaughterhouse Workers and Slaughtered Cattle in the Bahr El Ghazal Region of South Sudan

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT Introduction Leptospirosis is a major but under‐reported zoonotic disease, and epidemiological data from South Sudan remain limited. This study estimated the true prevalence of Leptospira spp. exposure and identified associated risk factors among slaughterhouse workers and slaughtered cattle in Western Bahr El Ghazal. Methods A cross‐sectional

Longitudinal Surveillance of Influenza A Virus Exposure in Wild Boars (Sus scrofa) in Spain (2015–2023): Serologic and Virologic Evidence of Subtype Infections and H5N1 Spillover Risk

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT Introduction Influenza A viruses (IAVs) are responsible for respiratory infections in a wide range of species, including birds, swine and humans. The role of wild boar (Sus scrofa) in IAV epidemiology remains underexplored. Here, we present a longitudinal serologic and virologic surveillance study of wild boars in Spain from 2015 to 2023 ...

Detection error influences both temporal seroprevalence predictions and risk factors associations in wildlife disease models

open access: yesEcology and Evolution, 2019
Understanding the prevalence of pathogens in invasive species is essential to guide efforts to prevent transmission to agricultural animals, wildlife, and humans. Pathogen prevalence can be difficult to estimate for wild species due to imperfect sampling

Genomics reveals historic and contemporary transmission dynamics of a bacterial disease among wildlife and livestock [PDF]

open access: yes, 2016
Whole-genome sequencing has provided fundamental insights into infectious disease epidemiology, but has rarely been used for examining transmission dynamics of a bacterial pathogen in wildlife.

Seroprevalence and Risk Factors for Hepatitis E Virus in a Metropolis of Northeastern Brazil: A Population‐Based Survey

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT Introduction Hepatitis E virus (HEV) is a leading cause of acute hepatitis worldwide. While traditionally linked to poor sanitation in endemic areas, evidence shows increasing circulation in developed settings. In Brazil, however, population‐based data remain limited.

Hepatitis E Virus Antibodies in Patients with Chronic Liver Disease

open access: yesEmerging Infectious Diseases, 2009
In the United States, the seroprevalence rate for hepatitis E virus (HEV) is ≈20%. This study examined HEV seroprevalence in persons with and without chronic liver disease.

A Retrospective Cross‐Sectional Study (2009–2023): Exploring Influenza A(H1N1)pdm09 Antibody Time Series in Humans and Swine and Vaccine Coverage in Two Target Groups

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT Introduction Swine may act as ‘epidemiological bridges’ and reservoirs for the emergence of novel zoonotic influenza viruses with pandemic potential. While bidirectional exchange of influenza A viruses at the swine–human interface is well recognised, data on the extent of interspecies transmission are limited.
