Isolating enterovirus and poliovirus isolated in patients with acute flaccid paralytic syndrome in 2005

ABSTRACT

Background: Paralysis has been eliminated in Vietnam in 2000. To maintain the achievement, Vietnam needs to have more than 90% of children under 1 age drinking 3 doses of OPV, controlling cases of acute flaccid paralysis and diagnosing for virology in laboratory to determine causes of the disease. Results of laboratory identifying Polio virus and enterovirus in patients with acute flaccid paralysis is evidence of successful in paralytic elimination annually in Vietnam.\r\n', u'Objectives: To of isolate polio virus and enterovirus in patients with acute flaccid paralysis suspected paralysis in 2005.\r\n', u'Subjects and methods: The study included 267 cases with acute flaccid paralysis from 29 provinces, cities in the North and six provinces in the Central of Vietnam during 2005.\r\n', u'Results:Results of surveillance for acute flaccid paralysis and indicators of samples tested in 2005 have reached the criteria regulated by the World Health Organization. 8 poliovirus strains and 56 other non-polio enterovirus strains were isolated from 538 stool specimens of above patients. All isolated poliovirus strains were confirmed as Sabin-like strains. 56 non-polio enterovirus strains included coxsaxkie A (3), conxsackieB (5), echoviruses (34), enterovirus 71 (1) and untyped enteroviruses (13). Wild polio virus was not isolated in 2005.\r\n', u'Conclusion: The result confirmed successfulness in maintaining of poliomyelitis free status in the North and 6 provinces of the Central of Vietnam in 2005.\r\n', u'\r\n', u'\r\n', u'
