The existence of a viral cause of hepatitis other than hepatitis A and hepatitis B was first recognized in the early 1970s following the development of diagnostic blood tests for hepatitis A and hepatitis B. Early studies showed that appreciable proportions of people presenting with acute hepatitis following blood transfusion or community-acquired hepatitis did not have any serologic evidence o...
To the Editor: Vaccinia virus (VACV) causes exanthematous disease (bovine vaccinia) in Brazil. Outbreaks of this disease in humans have been reported since the late 1990s and have spread throughout Brazil (1). Natural human infections with VACV occur by close contact with infected cattle during milking. Lesions can spread to secondary body sites (forearms, arms, and face). Thus, personto-person...

Spillover from mink to humans highlights SARS-CoV-2 transmission routes animals
The prospect of using whole genome sequence data to investigate bacterial disease outbreaks has been keenly anticipated in many quarters, and the large-scale collection and sequencing of isolates from cases is becoming increasingly feasible. While sequence data can provide many important insights into disease spread and pathogen adaptation, it remains unclear how successfully they may be used t...
The identification of transmission routes for bluetongue virus (BTV) is essential to improve the control of the disease. Although BTV is primarily transmitted by several species of Culicoides biting midges, there has been evidence of transplacental and oral transmission. We now report that IFNAR((-/-)) mice are susceptible to oral infection by BTV-8. Viraemia, clinical manifestations and tissue...
