Aug 21, 2018 · We’ll go over some of the main types, including how they’re spread, treated, and prevented. We’ll also list examples of each type of viral disease.
Viral diseases are mainly caused when a virus enters the human body and uses the host machinery to reproduce. If the body’s immune system fails to fight against viruses, it multiplies and spreads to other cells causing infections.
Virions of some of the most common human viruses with their relative size. Nucleic acids are not to scale. SARS stands as for SARS as for COVID-19, variola viruses for smallpox.
This is a list of infectious diseases arranged by name, along with the infectious agents that cause them, the vaccines that can prevent or cure them when they exist and their current status. Some on the list are vaccine-preventable diseases . List. See also. Infections associated with diseases. List of oncogenic bacteria.

Categorizing viral infections by the organ system most commonly affected (eg, lungs, gastrointestinal tract, skin, liver, central nervous system, mucous membranes) can be clinically useful, although certain viral disorders (eg, mumps) are hard to categorize.
Examples of retroviruses are the human immunodeficiency viruses and the human T-cell leukemia viruses. Once the provirus is integrated into the host cell DNA, it is transcribed using typical cellular mechanisms to produce viral proteins and genetic material.
Nov 20, 2020 · There are many types of viruses that cause a wide variety of viral diseases. The most common type of viral disease is the common cold, which is caused by a viral infection of the upper respiratory tract (nose and throat). Other common viral diseases include: Chickenpox.
