Is aseptic meningitis polio?

Aseptic meningitis from HIV occurs mostly at the time of seroconversion. HIV spreads to the meninges hematogenously, while rabies, polio, and herpesviruses are neurotrophic (i.e., spread through neurons).

What is Nonparalytic polio?

Nonparalytic polio (NPP) is commonly thought to be synonymous with “abortive polio,” in which the poliovirus neither entered the central nervous system nor damaged neurons. Described are two epidemic illness-“The Summer Grippe” and Iceland disease-apparently caused by a low virulence but neuropathic type 2 poliovirus.

What are the three types of poliomyelitis?

There are three wild types of poliovirus (WPV) – type 1, type 2, and type 3.

Is polio related to meningitis?

Meningitis (infection of the covering of the spinal cord and/or brain) occurs in about 1 out of 25 people with poliovirus infection. Paralysis (can’t move parts of the body) or weakness in the arms, legs, or both, occurs in about 1 out of 200 people with poliovirus infection.

What is the most common cause of aseptic meningitis of viral etiology?

The most common cause of aseptic meningitis is a viral infection, specifically by enteroviruses. In fact, 90 percent of all meningitis cases that are viral are caused by enteroviruses. Other viruses that may cause aseptic meningitis are varicella zoster virus, herpes, and mumps.

How does poliovirus cause paralysis?

Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. In about 0.5 percent of cases, it moves from the gut to affect the central nervous system, and there is muscle weakness resulting in a flaccid paralysis. This can occur over a few hours to a few days.

What kind of virus is poliovirus?

Poliovirus, a nonenveloped, positive-sense, single-stranded RNA virus, is a member of the Enterovirus genus within the family Picornaviridae.

What are the complication of poliomyelitis?

The most severe complication of polio is paralysis. This can lead to problems with breathing, swallowing, and bowel and bladder function. Post-polio syndrome can happen many years after the initial infection.

What is the pathophysiology of polio?

Acute poliomyelitis is a disease of the anterior horn motor neurons of the spinal cord and brain stem caused by poliovirus. Flaccid asymmetric weakness and muscle atrophy are the hallmarks of its clinical manifestations, due to loss of motor neurons and denervation of their associated skeletal muscles.
