Virology is the scientific study of viruses, including their structure, classification, evolution, replication, and interaction with host organisms. It also encompasses the study of viral diseases and the development of antiviral treatments and vaccines.
Viruses are much smaller than bacteria and are obligate intracellular parasites, meaning they require a host cell to replicate. Bacteria are single-celled organisms that can often reproduce independently and are living cells with their own cellular machinery.
Common viral diseases include the common cold, influenza (flu), measles, chickenpox, HIV/AIDS, hepatitis, herpes, and COVID-19. These range in severity and impact on human health.
Prevention often involves vaccination, hygiene practices, and public health measures. Treatment can include antiviral medications that target viral replication, and supportive care to manage symptoms, as antibiotics are ineffective against viruses.
