No, poliomyelitis is not a prokaryote. It is a virus that belongs to the Picornaviridae family and infects humans, causing the disease polio. Viruses are not classified as prokaryotes or eukaryotes as they are considered acellular infectious agents.

I believe your question is about Polio. Yes, Polio is caused by a virus, named after the disease itself - Poliovirus. Poliovirus is a positive sense single stranded RNA virus of the genus Enterovirus and family Picornaviridae.

Hepatitis A is a type of RNA virus belonging to the Picornaviridae family. It primarily infects the liver and is transmitted through oral-fecal route, contaminated food or water, or close personal contact with an infected person.

Polio is a word that can mean one of two things, the virus or the disease The Polio disease which you are referring to is called poliomyelitis. The organism that causes it is a viral organism (virus). The name of the virus that causes poliomyelitis (polio disease) is called Poliovirus. The virus is a normal RNA virus from the Picornaviridae and genus enterovirus family.

Hepatitis A virus (HAV) is classified with the enterovirus group of the Picornaviridae family. HAV has a single molecule of RNA surrounded by a small (27 nm diameter) protein capsid and a buoyant density in CsCl of 1.33 g/ml. Many other picornaviruses cause human disease, including polioviruses, coxsackieviruses, echoviruses, and rhinoviruses (cold viruses).

The hepatitis A virus (HAV or also Hepatovirus A) is a picornavirus species from the family of Picornaviridae, genus Hepatovirus. It contains no capsid, leaving it unenveloped with a single-strand RNA in a protein shell. In humans, HAV can cause an acute infection of the liver also known as Hepatitis A.

The disease polio is more specifically poliomyelitis, an infection by the virus called, logically, poliovirus, a species of enterovirus.
Another common name for polio in young children is infantile paralysis.

Rhinoviruses store their genetic information in RNA.
They belong to the Picornaviridae family, which is in Class IV of the Baltimore classification, that is, the viruses with positive-sense single-stranded RNA.

Many different viruses have been shown to cause the common cold. Wikipedia says that 99 varieties of rhinovirus have been identified as causes of the cold. Rhinovirus is a species in the genus Enterovirus of the Picornaviridae family of viruses, also according to Wikipedia.

It is a VIRUS. Poliovirus, the causative agent of poliomyelitis, is a human enterovirus and member of the family of Picornaviridae.
Poliovirus is composed of an RNA genome and a protein capsid. The genome is a single-stranded positive-sense RNA genome that is about 7500 nucleotides long.[3] The viral particle is about 30 nanometres in diameter with icosahedral symmetry. Because of its short genome and its simple composition-only RNA and a non-enveloped icosahedral protein coat that encapsulates it-poliovirus is widely regarded as the simplest significant virus.[4]
Poliovirus was first isolated in 1909 by Karl Landsteiner and Erwin Popper.[5] In 1981, the poliovirus genome was published by two different teams of researchers- by Vincent Racaniello and David Baltimore at MIT[6] and by Naomi Kitamura and others at the State University of New York, Stony Brook.[7] Poliovirus is one of the most well-characterized viruses, and has become a useful model system for understanding the biology of RNA viruses.
Poliomyelitis, often called polio or infantile paralysis, is an acute viral infectious disease spread from person to person, primarily via the fecal-oral route.[1] The term derives from the Greek poliós (πολιός), meaning "grey", myelós (µυελός), referring to the "spinal cord", and the suffix -itis, which denotes inflammation.[2]
Although around 90% of polio infections cause no symptoms at all, affected individuals can exhibit a range of symptoms if the virus enters the blood stream.[3] In about 1% of cases the virus enters the central nervous system, preferentially infecting and destroying motor neurons, leading to muscle weakness and acute flaccid paralysis. Different types of paralysis may occur, depending on the nerves involved. Spinal polio is the most common form, characterized by asymmetric paralysis that most often involves the legs. Bulbar polio leads to weakness of muscles innervated by cranial nerves. Bulbospinal polio is a combination of bulbar and spinal paralysis.[4]
