Chapter 4 Overview - Viruses, Prions, & Nursing

Stay ahead in infectious disease! This comprehensive overview unpacks the latest on prions, viruses, and critical public health strategies that every healthcare professional needs to master. Dive deep into the unique world of prion diseases, exploring how misfolded proteins lead to fatal neurodegenerative conditions like Creutzfeldt-Jakob disease in humans and mad cow disease in animals, and why standard sterilization methods fail against them. Gain a robust understanding of viral classification, morphology, and diverse replication strategies, including lytic, lysogenic, latent, and chronic infections, distinguishing how different viruses hijack host cellular machinery. We provide essential insights into clinically significant viruses: • SARS-CoV-2 (COVID-19): Understand its crown-like structure, infection pathway targeting throat and lungs, what causes pneumonia, and the mechanisms behind vaccine development. • Influenza: Explore the concepts of antigenic drift and shift that necessitate annual vaccinations, trace the history of pandemics like the devastating 1918 H1N1 and 2009 "swine flu," and learn about its classification, surface glycoproteins (HA and NA), and treatment. • Human Immunodeficiency Virus (HIV): Delve into the retroviral life cycle, its integration into the host genome leading to lifelong infection, the role of latent reservoirs, and the impact of antiretroviral therapy (ART). • Herpesviruses, Respiratory Syncytial Virus (RSV), and Ebola: Review their unique infection dynamics, from the lytic and latent cycles of Herpes Simplex Virus to the severe respiratory illnesses caused by RSV in vulnerable populations, and the hemorrhagic fevers associated with Ebola. Master diagnostic techniques including highly sensitive Nucleic Acid Amplification Tests (NAATs) like PCR and RT-PCR, rapid antigen and antibody tests, and serology, all crucial for accurate and timely patient management. Learn about current prevention and treatment strategies, from established vaccines and targeted antivirals (polymerase, reverse transcriptase, protease, neuraminidase, and entry inhibitors) to the promising frontier of phage therapy against antibiotic-resistant bacteria. Finally, recognize the critical role of nurses and healthcare workers in infection control, outbreak response, patient education, and advocacy during pandemics.
