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 include the common cold , gastroenteritis , COVID-19 , the flu , and rabies .
Virus tropism refers to the virus' preferential site of replication in discrete cell types within an organ. In most cases, tropism is determined by the ability of the viral surface proteins to fuse or bind to surface receptors of specific target cells to establish infection.

It includes all genera and subgenera of viruses listed by the International Committee on Taxonomy of Viruses (ICTV) 2022 release.

The exact symptoms of your 24-hour flu will depend on what, exactly, caused the illness. But if you happen to have norovirus, you’ll likely experience the following symptoms, according to the ...
Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms. Viruses are classified by phenotypic characteristics, such as morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.
One means of determining whether the cells are successfully replicating the virus is to check for a change in cell morphology or for the presence of cell death using a microscope. Other viruses may require alternative methods for growth such as the inoculation of embryonated chicken eggs (e.g. avian influenza viruses [ 4 ] ) or the intracranial ...
The disease has three phases: early (prodromal), cardiopulmonary, and recovery. Prodromal symptoms last for 1–5 days [1] and include flu-like symptoms such as fever, headache, muscle pain (myalgia), nausea, vomiting, dizziness, chills, coughing, and shortness of breath (dyspnea), as well as low platelet count in the blood (thrombocytopenia).
