TWiV discusses a twice-yearly antiviral for prevention of AIDS, the WHO pandemic plan, West Nile resurgence in the US, the BANAL SARS-CoV-2 related viruses reproduce in human cells but do not transmit among animal hosts, and an amino acid change in dengue virus that enhances midgut replication in mosquitoes but reduces pathogenicity in humans.
TWiV reviews resurgence of Lassa fever in West Africa, at least 3 paralytic cases of cVDPV2 in Zimbabwe, CWD from eating prion-laden plants, measles in New Orleans and Broward County Florida, failure of Florida Surgeon General to support vaccination, a measles variant in Switzerland, SARS-CoV-2 persistent infections, leaky blood-brain-barrier for long COVID brain fog, West Nile virus transmitted among mosquitoes by the excreta, and viroid-like colonists of human microbiomes.
TWiV notes the passing of virologist Michael BA Oldstone, a study to assess the performance of rapid antigen tests to detect symptomatic and asymptomatic SARS-CoV-2 infection, and the presence of antibodies to type I interferons in ~40% of patients with West Nile virus encephalitis.
Kathryn Hanley joins TWiV to discuss her career and the research in her laboratory on the molecular biology, evolution and ecology of emerging RNA viruses and their insect vectors.
TWiV summarizes cases of arbovirus disease during 2019 in the US, and explains a study that estimates infectiousness throughout the SARS-CoV-2 course of infection.
Vincent and Rich return to the University of Texas Medical Branch at Galveston to speak with Dennis Bente, Shannan Rossi, Nikos Vasilakis, and Scott Weaver about their work on viruses transmitted by mosquitoes and ticks.
Vincent travels to the University at Albany to speak with Cara, Rachel, and Alex about their careers and their work on stress granules, epitranscriptomics, and arboviruses.
The TWiV team discuss the use of quantum dots to study uncoating of influenza virus in real time, and induction of endothelial dysfunction by flavivirus NS1 proteins in a tissue-specific manner.
The TWiV team summarizes the discovery of Sin Nombre virus, and presents evidence that neurotropic flaviviruses can cause intestinal dysmotility syndromes after systemic infection of mice.
The TWiV team reveals that recent mumps virus outbreaks in the US are due to waning vaccine efficacy, and an intranasally delivered small interfering RNA that controls West Nile infection in the brain.
