This Week in Virology

TWiV travels to Porto, Portugal for the annual meeting of the European Society for Clinical Virology, where he speaks with Catherine and Corinne about their work on the Andes virus outbreak on the MV Hondius.

In his weekly clinical update, Daniel Griffin and Vincent Racaniello discuss their continuing struggle to understand the ongoing outbreak of cyclospora, decimation of US public health including 30% or greater loss of personnel from the CDC, continuing measles outbreaks here and aboard, a mumps outbreak in San Diego and a Hib death in Montana, criminalization of pediatricians in Texas, dengue...

TWiV explains a study testing how 16 hypothesized social and environmental drivers impact disease outbreaks, concluding that infectious disease spillover and emergence are multi-causal, and that no one-size-fits-all strategy can prevent epidemics and pandemics, and an analysis of Myotis bats, which shows that their remarkable longevity and immunity are linked through pleiotropic adaptations to...

In his weekly clinical update, Daniel Griffin and Vincent Racaniello continue their ongoing exasperation over 5 deaths in Pennsylvania associated with measles infections, the absurdity of RFK Jr.’s statement that AI is better informed than physicians, the outbreak of cholera, more deaths by raw milk products, spread of dengue virus in Florida, Ebola in DRC, refusal to acknowledge the benefits of...

TWiV explains discovery of a previously unknown mechanism of RNA-guided DNA recognition for genetic control that possibly predates the emergence of CRISPR pathways, and the possibility that Alzheimer’s Disease neuropathology evolved as a host defense response to microbial infection in the brain.

In his weekly clinical update, Daniel Griffin and Vincent Racaniello frustration continues over the increasing number of measles infections, Kennedy’s undermining of vaccines, perpetuation of autism- vaccine, autism-tylenol myths, an outbreak of hepatitis A virus in the US, the Ebola outbreak in Uganda, changes in reporting of virus infection and vaccine recommendations, Legionnaires disease and...

Roberto Cattaneo and Kalpana Yadav join TWiV at the 2026 meeting of the American Society for Virology to discuss how the absence of measles virus receptors in the brain selects for hyperfusogenic variants that spread neuron-to-neuron and cause subacute sclerosing panencephalitis, a rare but fatal long-term neurological sequela of measles infection. Host: Vincent Racaniello Guests: Roberto...

In his weekly clinical update, Daniel Griffin and Vincent Racaniello are angered by the continuous reporting of measles deaths in the US and around the world, the Ebola outbreak in Uganda, changes in reporting of virus infection and vaccine recommendations, establishing an NIH research center on vaccine harms, Legionnaires at Yankee stadium and the first time in more than half a century reporting...

Paul Bieniasz joins TWiV to discuss his lab’s discovery that the coronavirus nuclease NSP15 cuts viral RNA into oligonucleotides that are reinserted elsewhere in the viral RNA, generating insertion mutations at a frequency above 10⁻³ per genome, including new furin cleavage sites at the spike S1/S2 junction.

In his weekly clinical update, Daniel Griffin and Vincent Racaniello delve into dengue virus infections in Florida, recent human rabies infections in the US, proposed changes in biomedical funding including “converting” the Department of War into NIAID, the continuing controversy over the deaths of 2 children in Pennsylvania from measles, before Dr. Griffin deep dives into recent statistics RSV,...
