سابقه و هدف: فلج شل حاد (Acute Flaccid Paralysis) توسط عوامل مختلفی ایجاد می‌شود که مهم‌ترین عامل آن پولیو ویروس می‌باشد. هدف از پژوهش ارزیابی عوامل غیر پولیویی ایجاد کننده فلج در ایران می‌باشد. مواد و روش‌ها: در این تحقیق به منظور بهبود در قدرت جداسازی انتروویروسهای احتمالی موجود در مدفوع کودکان مبتلا به فلج شل حاد، تمام نمونه‌های مدفوع این کودکان، به پنج رده سلولی L20B، RD، Hep-2، Vero و GM...
Background. Acute flaccid paralysis (AFP) is described as sudden onset of flaccid paralysis in one or more limbs in children and mainly caused by polioviruses. AFP surveillance was managed by World Health Organization (WHO) for standard progress of poliomyelitis eradication. Methods. This study aimed to investigate clinical and etiological characterization of paralysis cases through a nationwid...
Acute Flaccid Paralysis (AFP) is a clinical syndrome characterized by rapid onset of weakness, in the respiratory muscles, swallowing and limbs; death because muscles failure. AFP surveillance crucial, clinicians are required to notify AFP cases among children below 15 years old epidemiology department with completion form. In this study, researcher analyzed investigation forms determine pict...
INTRODUCTION Human enteroviruses are common in children causing asymptomatic infections ranging from mild to severe illnesses. In Ghana, information on the prevalence of non-polio enterovirus causing acute flaccid paralysis is available but data on surveillance of these viruses in school children is scanty. Here, the prevalence of human enteroviruses among apparently healthy children in selecte...
Acute flaccid paralysis (AFP) surveillance has been conducted as part of the World Health Organization (WHO) strategy on poliomyelitis eradication. Aside from poliovirus, which is the target pathogen, isolation, and identification of non-polio enteroviruses (NPEVs) is also done by neutralization test using pools of antisera which can only identify limited number of NPEVs. In the Philippines, de...
BACKGROUND Poliovirus rapidly evolves by nucleic acid substitutions and genetic recombination with other polioviruses and non-polio enteroviruses. Evolving oral poliovaccine can rapidly revert to neurovirulence and undergo antigenic alterations. OBJECTIVES To evaluate the threat of vaccine-derived poliovirus (1-15% divergence from the respective Sabin strain) for a poliomyelitis-free populati...
Background and Aim: Iran National Polio Laboratory (NPL) is a member of the World Health Organization (WHO) Polio Laboratories Network. NPL receives stool specimens from acute flaccid paralysis (AFP) cases from all the provinces throughout Iran for poliovirus detection and identification. Furthermore, the NPL also detects non-polio enteroviruses (NPEVs) in these specimens. Recently, NPEVs have...
INTRODUCTION The last case of wild polio virus transmission occurred in Akwa Ibom state in October 2001; however, combination high routine immunization coverage with OPV, high quality AFP surveillance, mass immunization campaign in which two doses of potent oral polio vaccine is administered to eligible children and mop-up campaigns in areas with identified immunization or surveillance gaps has...
After exposure to the oral poliovirus vaccine (OPV), immunocompetent persons excrete poliovirus (PV) vaccine strains for a limited period. In contrast, immunodeficient individuals remain sometimes chronically infected, and in some cases, PV excretion times as long as 10 years have been reported. During prolonged replication in the human intestine, the PV vaccine strain almost invariably reverts...
هدف از مراقبت فلج شل حاد جستجو و بررسی موارد بیماری است تا بتوان از این طریق جمعیتهای در معرض خطر، مناطق پرخطر و جاهایی که ویروس وحشی کماکان وجود دارد را شناسایی و برای مقابله با آن برنامه ریزی نمود. در شبکه های کارآمد جهت بررسی کیفیت مراقبت شاخص هایی تعیین، که نشان دهنده روند مراقبت بیماری می باشد. مشاهده این شاخص ها وضعیت هر منطقه را مشخص و در بنرامه ریزی های بهداشتی نقش موثری ایفا می نماید. ...
