    #7 - ME/CFS: Causes, Symptoms and Unanswered Questions
    Mar 25 2026
    ME/CFS (myalgic encephalomyelitis / chronic fatigue syndrome) is a complex and often misunderstood disease that affects the nervous system, immune system, and energy metabolism. In this episode, Florian Krammer explains the key symptoms, including severe fatigue, post-exertional malaise, sleep disturbances, and cognitive dysfunction, as well as the different levels of disease severity.

    #6 – MPOX: What We Know About The Recent Outbreaks
    Mar 18 2026
    Mpox, formerly known as monkeypox, is a double-stranded DNA virus closely related to smallpox that has gained global attention in recent years. In this episode, Florian Krammer explains the biology of the virus, its complex life cycle, and its ability to spread both through zoonotic transmission from animal reservoirs such as rodents and through human-to-human contact, including close physical and sexual contact.

  • #5 – Epstein–Barr Virus: Why Almost Everyone Gets Infected

    #5 – Epstein–Barr Virus: Why Almost Everyone Gets Infected
    Mar 11 2026
    Epstein–Barr virus (EBV) is one of the most common human viruses, infecting around 90–95 percent of adults worldwide. In this episode, Florian Krammer explains the biology of EBV, a herpesvirus with a large DNA genome and a complex life cycle that includes both active replication and lifelong latent infection in B cells. The discussion covers how EBV spreads through saliva and close contact, why primary infection in adolescents often leads to infectious mononucleosis, and how the virus can persist silently in the body for decades.

    #4 – Human Papillomavirus: Why Vaccination Matters
    Mar 4 2026
    Human papillomaviruses are among the most common viruses infecting humans, with more than 200 known types and up to 80 percent of people exposed during their lifetime. In this episode, Florian Krammer explains how HPV infects epithelial cells and why certain high-risk types are responsible for the majority of cervical cancer cases.

    #3 – Avian Influenza: From Wild Birds to Humans
    Feb 25 2026
    Avian influenza, commonly known as bird flu, has become a global concern once again. In this episode, Florian Krammer explains the biology of influenza A viruses, how subtypes like H5N1 are defined by their hemagglutinin and neuraminidase proteins, and why segmented genomes allow these viruses to reassort and evolve. He outlines the difference between low and highly pathogenic avian influenza, the molecular basis of increased virulence, and the historical spread of H5N1 since the late 1990s.

    #0 – What Are Viruses?
    Feb 4 2026
    In the first episode of viroLOGICAL, Florian Krammer takes a fundamental look at viruses: What are viruses and why are they not considered living organisms? He explains how viruses replicate inside host cells, how they were first discovered, and why their size, shape and genetic makeup can differ so widely.
