The two viruses known to infect all vertebrates are the rabies virus and the influenza virus. Rabies virus, a member of the Lyssavirus genus, affects the central nervous system of mammals, while influenza viruses, particularly the types A and B, can infect a wide variety of vertebrates, including birds and mammals. These viruses have adapted to exploit the cellular machinery of diverse vertebrate hosts, showcasing their broad host range.
All mammals are vertebrates. The two main sections of the animal kingdom are invertebrates and vertebrates- and mammals fall into the vertebrates section!!
The two primary types of decomposed organisms in bacteria and viruses are saprophytic bacteria and viruses that infect dead or dying organic matter. Saprophytic bacteria break down dead organic material, recycling nutrients back into the ecosystem. In contrast, viruses, particularly bacteriophages, can infect and lyse bacterial cells, contributing to the decomposition process by releasing cellular contents back into the environment. Together, these organisms play a crucial role in nutrient cycling and ecosystem dynamics.
They don't have their own metabolism and they can't reproduce on their own, two reasons for which they are obligatory parasites. They have to infect other cells with metabolisms to reproduce.

Bilateral symmetry. This means that the animal's body can be divided into two equal halves along a single plane.
There are currently 20 families of viruses that infect humans. There are two additional viruses (Hepatitis D and Hepatitis E) which have not yet been assigned to a families but are clearly distinct from the other families infecting humans. Viruses replicate inside cells by hijacking strands of RNA to duplicate themselves. See the related link for more details on viral diseases.
Hantavirus infection is caused by a group of viruses that can infect humans with two serious illnesses: hemorrhagic fever with renal syndrome (HFRS), and Hantavirus pulmonary syndrome (HPS).
Vertebrates with two pairs of limbs are known as tetrapods.
Strand A flu refers to influenza viruses that belong to one of the two main types of influenza viruses (A and B). Influenza A viruses can infect both humans and animals, leading to seasonal flu outbreaks and occasional pandemics. These viruses can mutate and evolve rapidly, making them a significant public health concern.
Proteins,carbohydrates,nucleic acid and some have Lipids.Virus are also made up of those as other animals. Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment. Some naked viruses include poliomyelitis, warts, the common cold, chickenpox, shingles, mononucleosis, herpes simplex (cold sores), influenza, herpes viruses and HIV (AIDS). Some enveloped viruses include norovirus (stomach bug), rotavirus and human papillomavirus (HPV). The envelope can be damaged by freezing temperatures, chlorine, and phenol. If damaged the virus cannot infect. Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own. They are very small and can be considered ultramicroscopic. We were not able to see them with the best light microscopes as we could bacteria (prokaryotes). We have to use an electron microscope to see them as they are that small. This was not available until recently.
