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.

From the European Society for Clinical Virology 2022 Conference in Manchester UK, Vincent speaks with Richard Knight about prion diseases and the outbreak of bovine spongiform encephalitis that led to cases of variant Creutzfeldt-Jakob disease in humans.

TWiV revisits chronic wasting disease of cervids and the ability of the prions to infect meadow voles and raccoons, and the suggestion that stochastic assembly of influenza virus particles may play a role in phenotypic diversity.

Trudy joins the the TWiVlords to discuss new tests for detecting prions in the blood, and evidence showing that foamy retroviruses originated in the seas with their jawed vertebrate hosts at least 450 million years ago.

Vincent visits the Rocky Mountain Laboratories in Hamilton, Montana and speaks with Marshall, Sonja, and Byron about their work on tick-born flaviviruses, innate immunity, and prion diseases.
