Virus-Cell Interactions Part 2 Multicellular Hosts

The video tutorial by Professor Dave covers the basics of viral infections, focusing on terminology, host interactions, and the immune response. It explains the host range, tropism, and virulence factors of viruses, as well as the entry and dissemination of viruses in the body. The progression of viral diseases is outlined, including acquisition, incubation, replication, and immune response. The video also discusses the resolution of infections and the potential for immunopathology.
