A priority of the Global Polio Eradication Initiative (GPEI) 2013-2018 strategic plan is to evaluate the potential impact on polio eradication resulting from expanding one or more Supplementary Immunization Activities (SIAs) to children beyond age five-years in polio endemic countries. It has been hypothesized that such expanded age group (EAG) campaigns could accelerate polio eradication by el...

Objective: The objective of this study was to analyze the current strategies used for eradicating wild polio viruses (WPV) and to propose some innovative strategies that may help to accelerate the progress towards polio eradication. Methods: We assessed the current strategies proposed by the World Health Organization, and the effectiveness of the current trivalent oral polio vaccine types 1, 2 ...

OBJECTIVE To assess parent's knowledge and perceptions surrounding polio and polio vaccination, self-reported participation in polio supplementary immunization activities (SIAs) targeting children aged < 5 years, and reasons for non-participation. METHODS The mixed methods study began with a cross-sectional survey in Karachi, Pakistan. A structured questionnaire was administered to assess par...

BACKGROUND Multiple cases of paralysis, often resulting in death, occurred among young adults during a wild poliovirus (WPV) type 1 outbreak in Pointe Noire, Republic of Congo, in 2010. We conducted an investigation to identify factors associated with fatal outcomes among persons with poliomyelitis in Pointe Noire. METHODS Polio cases were defined as acute flaccid paralysis (AFP) cases report...

PROBLEM Many countries have weak disease surveillance and immunization systems. The elimination of polio creates an opportunity to use staff and assets from the polio eradication programme to control other vaccine-preventable diseases and improve disease surveillance and immunization systems. APPROACH In 2003, the active surveillance system of Nepal's polio eradication programme began to repo...

In April 2013, a case of wild polio virus (WPV) was detected in the Somalia capital Mogadishu. This inaugurated what is now referred to as the 2013-2014 Horn of Africa Polio outbreak with cases reported in Somalia, Kenya and Ethiopia. By the notification of the last polio case in August 2014, 223 cases of WPV had been reported in Somalia, Kenya and Ethiopia of which 199 in Somalia alone. The ou...

Polio eradication is on the cusp of success, with only a few regions still maintaining transmission. Improving our understanding of why some regions have been successful and others have not will help with both global eradication of polio and development of more effective vaccination strategies for other pathogens. To examine the past 25 years of eradication efforts, we constructed a transmissio...

introduction : viral meningitis is an inflammation of the leptomeninges as a manifestation of central nervous system (cns) infection, and more than 85% of viral meningitis cases are caused by non-polio enteroviruses. molecular methods such as polymerase chain reaction (pcr) are increasingly used to detect and type non-polio enteroviruses. here, we describe the impact of these viruses on aseptic...

The 2013 deadline for the worldwide goal to eradicate polio has come and gone, with a new endgame set for 2018.1,2 Although cases of polio have decreased by 99% worldwide since 1988, geopolitical conflicts have exacerbated its spread—Syria, Ethiopia, and Kenya have reported polio infections, and Afghanistan, Nigeria, and Pakistan remain endemic.3,4 The virus has resurfaced in Israel, and might ...
