Mild illnesses in humans include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), [1] [2] while more lethal varieties can cause SARS, MERS and COVID-19. [3] [4] As of 2021, 45 species are registered as coronaviruses, [5] whilst 11 diseases have been identified, as listed below.
3D still showing rabies virus structure. Rhabdoviruses have helical symmetry, so their infectious particles are approximately cylindrical in shape. They are characterized by an extremely broad host spectrum ranging from plants [citation needed] to insects [citation needed] and mammals; human-infecting viruses more commonly have icosahedral symmetry and take shapes approximating regular polyhedra.

Rabies is caused by lyssaviruses, including the rabies virus and Australian bat lyssavirus. [4] It is spread when an infected animal bites or scratches a human or other animals. [1] Saliva from an infected animal can also transmit rabies if the saliva comes into contact with the eyes, mouth, or nose. [1]
Coronavirus disease 2019 (COVID-19) Yes: Coxsackie B virus: Coxsackie B virus infection Enterovirus infection is diagnosed mainly via serological tests such as ELISA and from cell culture. There is no well-accepted treatment for the Coxsackie B group of viruses. Under research [10] PRNP: Creutzfeldt–Jakob disease (CJD) No Crimean-Congo ...
Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans. The Centers for Disease ...
A wide variety of samples can be used for virological testing. The type of sample sent to the laboratory often depends on the type of viral infection being diagnosed and the test required. Proper sampling technique is essential to avoid potential pre-analytical errors.
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 , corona , flu , pneumonia .
