Key Concepts in Virology
Virology, the study of viruses, is a field of biology that examines the structure, classification, and evolution of viruses, as well as how they infect and exploit host cells for reproduction.
- Virus Structure: Made up of genetic material (DNA or RNA), a protein coat, and sometimes lipid envelopes.
- Virus Classification: Based on morphology, genetic makeup, and mode of replication.
- Viral Pathogenesis: How viruses cause disease and their interaction with the host's immune system.
- Transmission: Mechanisms of spread including direct contact, airborne, and vector-borne transmission.
- Preventive Measures: Vaccination, antiviral drugs, and public health strategies.
Viruses have a fascinating interaction with their hosts, often leading to the co-evolution of both the virus and host species.
