Dr. Daniel Griffin, a physician specializing in infectious diseases, shares his insights on recent health concerns. He discusses the E. coli outbreak linked to McDonald’s onions and touches on the rising global measles crisis. The underutilization of influenza antivirals for youth is examined, alongside a $350 million mpox vaccination strategy. Griffin also highlights the dynamics of SARS-CoV-2 transmission and ongoing research into long COVID, emphasizing the necessity of credible health communication in the face of misinformation.

Discover a novel H5N1 reassortant virus causing concern in Cambodia, and learn about the circulation of vaccine-derived polioviruses. Explore the intriguing dynamics of infectious parvovirus B19 and its interactions with host cells. Delve into dengue virus infections and the role of B cells in disease severity. The discussion also uncovers viral cloaking mechanisms and fascinating ecological insights related to raccoon dogs. Finally, reflect on the impact of vaccination programs and the scientific community's response to recent political shifts.

Dr. Daniel Griffin, an infectious disease expert, provides crucial clinical updates on emerging viral threats. He discusses the alarming H5N1 flu case in Canada and its implications for health, alongside a tragic increase in flu-related pediatric deaths. The conversation dives into the Marburg outbreak in Rwanda and the ongoing mpox situation. Griffin also highlights the impact of mistrust on COVID-19 vaccine uptake, the efficacy of Paxlovid, and new findings on long-term cardiac effects from SARS-CoV-2. This episode is packed with vital insights for public health awareness.

TWiV notes the passing of virologist Diane Griffin, first H5N1 influenza virus in US pigs, Innate immune control of influenza virus interspecies adaptation via IFITM3, and antiviral trained innate immunity in alveolar macrophages after SARS-CoV-2 infection reduces secondary influenza A virus disease.

Dr. Daniel Griffin, an expert in infectious diseases, shares crucial insights on the mpox outbreak, reporting over 1,100 deaths this year, especially affecting young girls. He discusses the alarming Marburg virus situation in Rwanda and updates on CDC vaccine recommendations for RSV and pneumonia. As influenza season approaches, Griffin highlights COVID-19 transmission risks indoors and the importance of vaccines for older adults. He also connects the dots between Myalgic Encephalomyelitis and long COVID symptoms, urging attention to overlapping health issues.
