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...

We consider the problem of the optimal route selection in the presence of Rician fading channel. The variation in the signal strength due to fading is an overlooked fact in the wireless sensor networks. The conventional route selection strategies neglect the effect of fading and provide the low throughput routes for the data transmission. We consider the underlying dynamics of the wireless comm...

Human infections with Nipah virus in Malaysia and Bangladesh are associated with markedly different patterns of transmission and pathogenicity. To compare the 2 strains, we conducted an in vivo study in which 2 groups of ferrets were oronasally exposed to either the Malaysia or Bangladesh strain of Nipah virus. Viral shedding and tissue tropism were compared between the 2 groups. Over the cours...

Opportunistic invasive fungal infections, in particular due to Aspergillus fumigatus, are an increasing problem in hospitalized, immunocompromised patients [1-3]. Patients at risk are those with hematologic malignancies [4,5], bone marrow or solid organ transplant recipients [6,7], patients with chronic granulomatous disease [8] and AIDS patients [9]. These patient groups have in common severe ...

Hepatitis E virus (HEV) is believed to be transmitted by the fecal-oral route in pigs. To date, in experiments, HEV has been transmitted successfully only by the intravenous or intrahepatic route. To assess the route of HEV transmission, 27 pigs were separated into nine groups of three pigs. Positive-control pigs were inoculated intravenously with swine HEV and served as the source of HEV for t...

Motivated by the desire to assess nonpharmaceutical interventions for pandemic influenza, we seek in this study to quantify the routes of transmission for this disease. We construct a mathematical model of aerosol (i.e., droplet-nuclei) and contact transmission of influenza within a household containing one infected. An analysis of this model in conjunction with influenza and rhinovirus data su...

For centuries, tuberculosis has been identified as a burden to seafarers. In this study, we assessed the magnitude of tuberculosis among merchant seafarers today. Furthermore, we identified the most likely routes of M. tuberculosis transmission by the use of DNA fingerprinting. A database containing all culture-positive tuberculosis cases in Denmark in 1992-2003 was combined with a register on ...

BACKGROUND Use of emollient prior to phototherapy could enhance UV transmission through psoriasis plaques on the condition that the emollient is not photoprotective. Emollient pretreatment with narrow-band phototherapy (313 nm) has not been studied extensively. We conducted a study to assess if vaseline oil prior to UVB TL01, in chronic psoriasis plaques could accelerate psoriasis clearance. ...
