Eight waterworks in The Netherlands, which use surface water as their raw water source, were sampled repeatedly between November 1978 and June 1981. At five waterworks , 30 of 45 samples of raw water contained viruses. Of 55 samples of partially purified water, 11 were virus positive, including 8 after coagulation, sedimentation, and rapid sand filtration, 2 after storage, coagulation, sediment...
bc medical journal vol. 56 no. 10, december 2014 bcmj.org ABSTRACT: Enterovirus D68 is increasingly being reported as a cause of severe respiratory illness across North America, with several children in Canada testing positive for this virus and experiencing concurrent polio-like symptoms. In one recent case in British Columbia, a 9-yearold patient presented with acute flaccid paralysis of his ...
OBJECTIVE To study the incidence, aetiology, clinical characteristics and management of paediatric aseptic meningitis in a paediatric hospital in Singapore. MATERIALS AND METHODS Patients with cerebrospinal fluid (CSF) pleocytosis, a negative Gram stain and bacterial culture were reviewed retrospectively from 1 January to 31 December 2000. Eighty-seven patients who fulfilled the criteria for ...
Enterovirus 74 (EV74) is a rarely detected viral infection of children. In 2010, EV74 was identified in New Zealand in a 2 year old child with acute flaccid paralysis (AFP) through routine polio AFP surveillance. A further three cases of EV74 were identified in children within six months. These cases are the first report of EV74 in New Zealand. In this study we describe the near complete genome...
In 2000, the island of Hispaniola, home to Haiti and the Dominican Republic, was the first place where the existence of circulating vaccine derived poliovirus (cVDPV) was demonstrated [1]. As a live product, oral polio vaccine (OPV), once excreted, could enter the environment, reassort with other enteroviruses, and produce cVDPV [2]. After the investigation of that outbreak, the first of a doze...
A single-tube, single-primer-set reverse transcription-PCR assay was developed for the rapid detection of polioviruses in infected tissue culture fluids and clinical materials. The poliovirus-specific PCR primers are located in the VP1-2A region of the poliovirus genome. They generate a 290-bp product and can be used in duplex reactions with general enterovirus primers. The primers span the reg...
Abstract : BACKGROUND: Guillain-Barrsyndrome is an autoimmune peripheral neuropathy characterized by progressive symmetrical and ascending weakness and areflexia. Non-polio enterovirus (coxsackievirus type A and B, ECHO virus and enteroviruses) infections are seen in infants and children ranging from asymptomatic infection to life-threatening serious clinical conditions. Paralysis has been repo...
In 2012 no cases of poliomyelitis were reported through clinical surveillance in Australia, and poliovirus was not detected through virological surveillance. Australia conducts surveillance for cases of acute flaccid paralysis (AFP) in children less than 15 years as the main mechanism to monitor its polio-free status in accordance with World Health Organization (WHO) recommendations. Cases of A...
We have searched, using a sensitive nested-PCR, for enterovirus RNA in cerebrospinal fluid and post mortem central nervous system (CNS) tissue from patients with previous poliomyelitis with or without late functional deterioration, patients with motor neuron disease (MND), and control patients with other neurological disease or without neurological disease. Enterovirus RNA was detected in patie...
Immunodeficiency-associated vaccine-derived polioviruses (iVDPVs) have been isolated from primary immunodeficiency (PID) patients exposed to oral poliovirus vaccine (OPV). Patients may excrete poliovirus strains for months or years; the excreted viruses are frequently highly divergent from the parental OPV and have been shown to be as neurovirulent as wild virus. Thus, these patients represent ...
