Flaccid paralysis is an illness characterized by weakness or paralysis and reduced muscle tone The term acute flaccid paralysis (AFP) is often used to describe a sudden onset, as might be found with polio. AFP is the most common sign of. Nationwide AFP (acute flaccid paralysis) surveillance is the gold standard for often confirms wild poliovirus infections in the absence of cases of paralysis. To thoroughly describe the clinical, laboratory, and electrodiagnostic features of this paralysis syndrome, we evaluated acute flaccid paralysis that developed in.

The pathology of human West Nile virus infection.

A years surveillance of poliomyelitis and acute flaccid paralysis in Fars Province, Southern Iran. Environmental surveillance involves testing sewage or other environmental samples for the presence of poliovirus. Rapid onset of weakness or paralysis, characterized as flaccid without other obvious causes e. All patients exhibited features typical for polio, including acute flaccid paralysis without paresthesias or sensory loss, marked asymmetric weakness, diminished or absent deep tendon reflexes in the affected limbs, and weakness that developed during an acute infectious process.

Upper motor neuron lesion: Then in order zcute estimate the annual incidence rate of AFP in population aged less than 15, we used the Poisson regression. Bull World Health Organ.

Acute Flaccid Paralysis | Queensland Health

Sensation paealysis slightly diminished to vibration and proprioception in toes bilaterally but preserved to light touch, pinprick, and temperature. Stool examination was adequate in all cases and was sufficient to exclude poliomyelitis.

The patient had no headache, neck stiffness, or alteration of mental status Table 2. Nervous and musculoskeletal systems Enterovirus-associated diseases.


Physicians should suspect WNV infection in patients from areas where WNV is being transmitted and who have acute, painless, asymmetric weakness, even if unaccompanied by fever or apparent meningoencephalitis. Your health care provider will provide treatment based on the cause of acutd condition. Sensory test results were normal.

Louis encephalitis virus indicated WNV infection Systematic environmental sampling e. Rlaccid, the surveillance system was organized to identify the clinically suspected cases of poliomyelitis, and then to track them using laboratory investigations to either rule in or paralyiss out the diagnosis of poliomyelitis caused by the wild poliovirus.

Weekly Epidemiol Record ; 73 Abstract Objective The surveillance of acute flaccid paralysis AFP is a key strategy for monitoring the progress of poliomyelitis eradication and is a sensitive measure for detecting potential cases of poliomyelitis and poliovirus infection.

Acute Flaccid Paralysis and West Nile Virus Infection

Mean annual incidence rate of AFP perunder 15 year old children by age and gender using Poisson regression analysis. Search our Website Search for: A coarse bilateral upper extremity action tremor was noted.

Electrodiagnostic studies showed widespread denervation, reduced CMAP amplitudes in all nerves of the lower limbs and right upper limb, and normal SNAP responses, consistent with a severe, asymmetric process affecting anterior horn cells or motor axons.

The term acute flaccid paralysis AFP is often used to describe paealysis sudden onset, as might be found with polio.

Acute Flaccid Paralysis and West Nile Virus Infection

The initial specimen for one patient patient 5, Table 1 was tested with a slightly modified IgM antibody assay at a commercial laboratory World Health Organization; Meanwhile, the increase in notifications suggests an increased rate of enthusiasm in reporting.

Admission laboratory findings showed peripheral leukocytosis and CSF pleocytosis Table 3. Emerg Infect Dis [serial online] Jul [ date cited ]. Differential diagnosis of acute flaccid paralysis and its role in poliomyelitis acjte. This observational study was conducted from January to December at the Kurdistan Center for Disease Control and the Department patalysis Pediatrics. J Infect Dis ; Suppl 2: The assertion that WNV infection involves anterior horn cells and causes a polio-type syndrome has a pathologic basis.


Although computed tomography CT and magnetic resonance imaging MRI of the brain showed normal results, heparin was administered for suspected evolving stroke. Neurologic examination showed normal cognition, asymmetric flaccid paralysis of the left arm and leg with absent reflexes, hyporeflexic weakness of the right arm and leg, and weakness of bulbar muscles Table 2.

Flaccid paralysis

Consequently, there is a need to improve the virological culture technique of patients with AFP in our country. Journal List Emerg Aadalah Dis v.

Data were acuts out by visiting or contacting a feed-forward site. Association of Campylobacter jejuni infection and GuillainBarre syndrome: An AFP surveillance programme is conducted to increase case yield of poliomyelitis. Relationship between occurrence of Guillain-Barre syndrome and mass campaign of measles and rubella immunization in Iranian 5—14 years old children.

In WNV-infected birds, lesions adalab viral antigen were most prominent in the cerebellum and acjte gray matter of the spinal cord Case definition of what should be reported was embedded and defined clearly. WNV antigen was mainly localized within the gray matter of the spinal cord, with no lesions apparent in peripheral nerves or ganglia. The effective surveillance system in Kurdistan and its evaluation may serve as a model for the surveillance of other infectious diseases.
