The surveillance has revealed three independent importations of wild-type poliovirus. In addition, several vaccine-derived polioviruses have been detected in various locations in Egypt. In addition to acute flaccid paralysis (AFP) surveillance, environmental surveillance can be used to monitor the wild poliovirus and vaccine-derived poliovirus circulation in populations in support of polio eradication initiatives.<\/jats:p>","DOI":"10.1128\/aem.00491-12","type":"journal-article","created":{"date-parts":[[2012,5,12]],"date-time":"2012-05-12T05:26:50Z","timestamp":1336800410000},"page":"5406-5409","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":31,"title":["Detection of Imported Wild Polioviruses and of Vaccine-Derived Polioviruses by Environmental Surveillance in Egypt"],"prefix":"10.1128","volume":"78","author":[{"given":"Soile","family":"Blomqvist","sequence":"first","affiliation":[{"name":"National Institute for Health and Welfare (THL), Department of Infectious Disease Surveillance and Control, Virology Unit, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laila","family":"El Bassioni","sequence":"additional","affiliation":[{"name":"Holding Company for Biological and Vaccine Production (VACSERA), Department of Research and Development, World Health Organization, Regional Reference Laboratory for Polio Diagnosis, Cairo, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eman M.","family":"El Maamoon Nasr","sequence":"additional","affiliation":[{"name":"Holding Company for Biological and Vaccine Production (VACSERA), Department of Research and Development, World Health Organization, Regional Reference Laboratory for Polio Diagnosis, Cairo, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anja","family":"Paananen","sequence":"additional","affiliation":[{"name":"National Institute for Health and Welfare (THL), Department of Infectious Disease Surveillance and Control, Virology Unit, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana","family":"Kaijalainen","sequence":"additional","affiliation":[{"name":"National Institute for Health and Welfare (THL), Department of Infectious Disease Surveillance and Control, Virology Unit, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Humayun","family":"Asghar","sequence":"additional","affiliation":[{"name":"World Health Organization, Eastern Mediterranean Regional Office, Cairo, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Esther","family":"de Gourville","sequence":"additional","affiliation":[{"name":"World Health Organization, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Merja","family":"Roivainen","sequence":"additional","affiliation":[{"name":"National Institute for Health and Welfare (THL), Department of Infectious Disease Surveillance and Control, Virology Unit, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0042-6822(91)90434-D"},{"key":"e_1_3_2_3_2","first-page":"145","article-title":"Resurgence of wild poliovirus type 1 transmission and consequences of importation\u201421 countries, 2002\u20132005","volume":"55","author":"Centers for Disease Control and Prevention (CDC)","year":"2006","unstructured":"Centers for Disease Control and Prevention (CDC). 2006.
