Daniel Griffin provides a clinical update on COVID-19, including analysis of the dexamethasone trial, and then we discuss two Ebolavirus outbreaks in DRC, clinical and virological aspects of asymptomatic SARS-CoV-2 infections, age-dependent effects on transmission, and answer listener email.
Vincent and Rich discuss the SARS-CoV-2 D614G amino acid change in the spike glyprotein, duration of infectious virus shedding from patients, virus transmission among hamsters infected in the laboratory, and tackle listener email.
Daniel Griffin provides a clinical update on COVID-19, then Ralph Baric joins TWiV to discuss SARS-CoV-2 transmission, vaccines, diagnostic tests, and a new animal model from his laboratory that does not use transgenic mice.
Ralph Baric joins TWiV to dissect the coronavirus pandemic caused by SARS-CoV-2, including discussion on community spread, asymptomatic infections, origin of the virus, transmission, vaccine development, and much more.
In this week’s coverage of the coronavirus epidemic, the TWiV team discusses the fatality rate, China’s initial reaction to the outbreak, conspiracy theories, how long the virus remains infectious on surfaces, and evidence for virus in the intestinal tract.
The TWiVerers continue their coverage of the new coronavirus outbreak in China, as the number of cases increase dramatically and the virus begins person-to-person transmission in other countries.
The TWiV hosts review persistence of Ebola virus after the end of the Liberian outbreak, and the potential role of two herpesviruses in the pathogenesis of Alzheimer’s disease.
Vincent, Kathy, and Alan review the ongoing outbreak of Ebola virus in the Democratic Republic of the Congo, and the finding that mutations identified in the 2015 West African outbreak do not alter pathogenesis in animals.
The TWiV Masters discuss serologic evidence of Ebolavirus infection in a population with no outbreaks, and the set of endogenous viral elements in the mosquito genome.
The TWiV hosts discuss a plant virus that infects a fungus, and whether you need to work insane hours to succeed in science.
