  2. Viral pathogenesis - Wikipedia

    en.wikipedia.org/wiki/Viral_pathogenesis

    A viral infection does not always cause disease. A viral infection simply involves viral replication in the host, but disease is the damage caused by viral multiplication. [5] An individual who has a viral infection but does not display disease symptoms is known as a carrier. [17] Mechanisms by which viruses cause damage and disease to host cells

  3. Introduction to viruses - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_viruses

    Viruses cause different diseases depending on the types of cell that they infect. Some viruses can cause lifelong or chronic infections where the viruses continue to reproduce in the body despite the host's defence mechanisms. [52] This is common in hepatitis B virus and hepatitis C virus infections. People chronically infected with a virus are ...

  4. Virus - Wikipedia

    en.wikipedia.org/wiki/Virus

    Some viruses cause no apparent changes to the infected cell. Cells in which the virus is latent and inactive show few signs of infection and often function normally. [86] This causes persistent infections and the virus is often dormant for many months or years. This is often the case with herpes viruses. [87] [88]

  5. Outline of infectious disease concepts - Wikipedia

    en.wikipedia.org/wiki/Outline_of_infectious...

    The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.

  6. Germ theory of disease - Wikipedia

    en.wikipedia.org/wiki/Germ_theory_of_disease

    Their growth and reproduction within their hosts can cause disease. "Germ" refers to not just a bacterium but to any type of microorganism, such as protists or fungi, or other pathogens that can cause disease, such as viruses, prions, or viroids. [1] Diseases caused by pathogens are called infectious diseases. Even when a pathogen is the ...

  7. Infection - Wikipedia

    en.wikipedia.org/wiki/Infection

    As bacterial and viral infections can both cause the same kinds of symptoms, it can be difficult to distinguish which is the cause of a specific infection. [11] Distinguishing the two is important, since viral infections cannot be cured by antibiotics whereas bacterial infections can. [12]

  8. Viral disease - Wikipedia

    en.wikipedia.org/wiki/Viral_disease

    A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [ 1 ] Examples are the common cold , gastroenteritis and pneumonia .

  9. Virology - Wikipedia

    en.wikipedia.org/wiki/Virology

    Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
