afp surveillance guidelines pakistan

Acute Flaccid Paralysis (AFP) Surveillance of polio virus in Pakistan is a systematic collection, analysis and interpretation of data and the dissemination of information. The programme conducts periodic stool surveys among children from high risk populations who may be carrying the poliovirus without any signs of paralysis, or wherein circulation has been difficult to detect through regular AFP surveillance. In the years before the VPV program was introduced (ie, 2011 and 2012), the majority of AFP cases were reported through public healthcare facilities, such as hospitals and maternal and child health centers. Stool specimen adequacy rates have been consistently high, and AFP cases have been detected in a timelier manner since the program was introduced. Progress towards poliomyelitis eradication: Pakistan, January 2016–September 2017 Performance of acute flaccid paralysis (AFP) surveillance and incidence of poliomyelitis, 2017 17 November 2017, vol. Despite an expansion in the number of reporting sites by the national polio program, VPVs have accounted for the majority of AFP cases detected in Somalia over the past 3 years, that is, from 2014 to 2016. These samples are collected routinely by the Global Polio Eradication Initiative to detect transmission of wild-type poliovirus or VDPVs that rarely emerge as a result of reversion of the Sabin strains contained within the live-attenuated OPV. From 2018 to 2019, the number of WPV1 cases increased from 21 to 29 in Afghanistan (38% increase) and from 12 to 147 in Pakistan (1,125% increase). Through case search methods, such as house-to-house and healthcare facility visits, VPVs identify incident AFP cases using an active surveillance model to support routine reporting from public facilities and private healthcare providers. Wassilak SG, Oberste MS, Tangermann RH, Diop OM, Jafari HS, Armstrong GL. Similarly, the mean duration to case notification decreased from 4.8 (95% CI, 4.32–5.21) days in 2014 to 3.8 (3.3–4.34) days in 2016 among all other reporting sources. Objective: To evaluate acute flaccid paralysis (AFP) surveillance system in Khyber Pakhtunkhwa (KPK) – Pakistan.. Methods: This descriptive cross-sectional study was conducted at directorate general health services office KPK, Peshawar from 10th November – 31st December, 2012. If the cause is poliomyelitis, this may result in permanent disability, and outcomes could sometimes be fatal [4, 5]. 1), focussing on major transportation hubs, and areas with either highly mobile populations or areas associated with suboptimal AFP surveillance or vaccination coverage. Over the past couple of years, the number of sites for environmental surveillance has increased, making it the largest environmental surveillance network in the world. In Pakistan, authorities have struggled to present a cohesive national strategy to control the coronavirus. Immunization Officer, Pune Municipal Corporation Date : 20.08.2010 2. Among the 25 districts that were either partially or completely inaccessible for polio immunization activities during 2011–2012, NPAFP rates were similar to those reported nationally. Strengthening AFP surveillance systems is thus seen not just as essential to interrupting poliovirus circulation in areas with ongoing transmission but also for protecting the gains already achieved in places where the disease has been eliminated. We also reviewed and analyzed AFP surveillance data for all cases reported in Somalia from January 2011 to November 2016. Currently, Pakistan has a well-functioning and sensitive AFP surveillance system at national, provincial, and district levels. The detection of PV in some countries (e.g., Afghanistan, Nigeria, Pakistan, and Somalia) that is highly diverged from previously identified PV isolates indicates that WPV or VDPV transmission remained undetected by AFP surveillance even when AFP performance indicators were met at the state/provincial level . Building trust at the grassroots level through community-based programs is beneficial on multiple levels because programs like the VPV program often evolve to encompass other disease surveillance and prevention activities. The programme is able to identify where the polio virus is circulating through its highly sensitive surveillance activities. The establishment of the VPV program to supplement existing structures in place for AFP surveillance has proved to be of vital importance in enhancing the country’s capacity to mount an effective response to outbreaks and maintain its polio-free status. We compared the NPAFP rate in 2015, the year after the 2013–2014 polio outbreak, to the rate in 2012, the year before the outbreak, by calculating the incidence rate ratio using a Poisson regression model, adjusting for geopolitical zones. More importantly, cases are being reported faster by both VPVs and other sources, as the mean interval from paralysis onset to reporting of a case improved from 5.4 days in 2014 to 3.7 days in 2016 for VPVs and from 4.8 to 3.8 days for other sources. The success of GPEI in drastically reducing the number of polio cases reported worldwide has been well documented [22–25]. AFP surveillance performance indicators should be monitored at all levels Depth of analysis depends on the level at which it is being conducted. Using a Poisson regression model adjusting for geopolitical zone, the incidence rate ratio for NPAFP cases was 1.7 (95% CI, 1.4–2.1; P < .001) when comparing the NPAFP rate in 2015, the year after the outbreak, to that of 2012, the year before outbreak onset. Disclaimer. These activities includes testing stool samples of children suffering from acute flaccid paralysis (the clearest symptom the virus) and testing samples taken from sewage water across the country. The patterns of reporting held in 2013, the first year of the polio outbreak, with public healthcare facilities again being the main reporting source for AFP cases. Documents reviewed include program description documents outlining terms of reference for volunteers. Volunteers involved in the program, commonly referred to as VPVs, were recruited from local communities in nearly all districts of the country, with early priority given to districts designated as high risk based on predefined criteria. Along with the decline in case reporting, the national NPAFP rate decreased from 3.2 to 2.8 cases per 100000 persons aged <15 years when comparing case detection rates in 2011 to 2012 (Figure 1). AFP case-reporting in areas in Somalia with access limitations, 2011–2016. Hagan JE, Wassilak SG, Craig AS, et al. Much of this success is predicated on the ability of countries to track and detect the emergence of new polio cases in places with active circulation of WPV based on surveillance for AFP cases. The success of these programs in improving AFP case detection has been demonstrated in countries such as Niger and Tanzania [28, 29]. Efforts are a bit better in Pakistan than in Afghanistan, where polio surveillance staff are now also conducting surveillance for Covid-19. In addition to AFP surveillance, environmental surveillance helps enhance the sensitivity of surveillance for polioviruses. The Global Polio Eradication Initiative (GPEI) has made tremendous gains in the last 28 years, with over 99% reduction in wild poliovirus (WPV) [1,2,3].Poliomyelitis is characterized by sudden weakness or floppy paralysis of any of the limbs, most especially in children [4,5,6,7,8].Acute flaccid paralysis (AFP) surveillance is the gold standard for poliomyelitis control and prevention. There are currently 60 sampling sites for environmental detection in 40 towns and districts of the country. Given the increasing threat posed by insecurity to polio eradication efforts in places like Nigeria [30] and Afghanistan [9, 31], such programs will play an increasingly prominent role in bringing the goal of disease eradication within reach. Any child under 15 years of age with AFP* or any person of any age with paralytic illness if polio is suspected Once an AFP case is identified, VPVs immediately notify the district polio officer, and a case investigation is begun. In addition to poliomyelitis, AFP cases may have several other causes, including Guillain-Barré syndrome and transverse myelitis [6]. Systems for AFP surveillance are particularly crucial in countries like Somalia, where the dilapidated healthcare infrastructure makes for increased vulnerability to polio outbreaks despite the elimination of indigenous WPV transmission. During 2011–2016, there was significant variation in AFP case counts and the NPAPF rates in Somalia. Improved AFP surveillance will also serve as a key factor for certification of the country and continent as polio free when the disease is eventually eliminated from Africa. 9. Mbaeyi C, Saatcioglu A, Tangermann RH, Hadler S, Ehrhardt D. Sousa IPJr, Burlandy FM, Oliveira SS, et al. ‘Adequate’ stool specimens are two stool specimens of sufficient quantity for laboratory analysis, collected at least 24 hours apart, within 14 days after the onset of paralysis, and arriving in the laboratory by reverse cold chain and with proper documentation. We then calculated the NPAFP rates per 100000 persons aged <15 years for each of the years under review. Current scenario of Polio 3. Stool samples of children with Acute Flaccid Paralysis (AFP) were collected from Khyber Pakhtunkhwa (KP) and Federally Administered Tribal Areas (FATA) of Pakistan as per WHO guidelines within 14 days from the date of onset. In the long run, such a program could help ameliorate deficiencies in the country’s healthcare system for the prevention and control of other diseases of public health significance. Intensified surveillance activities during the outbreak led to a 132% increase in the NPAFP rate in 2013. Detection of poliovirus circulation is often predicated on the ability to identify AFP cases and test their stool specimens for poliovirus infection in a timely manner. Similarly, identification and reporting of an AFP case within 7 days of paralysis onset is an indicator of the timeliness of the surveillance system; hence, countries are required to identify and report ≥80% of AFP cases within 7 days of paralysis onset in order to meet the benchmark for timeliness [7]. Although we could not determine from our data whether AFP cases identified by VPVs could have otherwise been detected by other reporting sources, our findings strongly suggest that much of the improvement in surveillance has been driven by the activities of VPVs. Environmental surveillance involves testing sewage or other environmental samples for the presence of poliovirus. Please check for further notifications by email. AFP surveillance 1. Pogka V, Labropoulou S, Emmanouil M, et al. Your comment will be reviewed and published at the journal's discretion. •New countries have initial funding for pilots: Pakistan, India, China •Most countries with AFP surveillance do detect iVDPVsin paralyzed children as part of AFP or other surveillance on their own •Priority countries are being identified in each WHO region to roll-out systematicsurveillance utilizing these guidelines focusing on PID VPVs accounted for only 2% of reported cases in 2013, having begun their activities in September of the same year. During 2014–2016, no statistically significant difference was found between adequacy of stool specimens reported by VPVs (98.3%) and those reported by other sources (96.8%). This project was funded and supported by the US Centers for Disease Control and Prevention. We computed the mean number days from paralysis onset to case reporting and 95% confidence intervals (CIs). AFP case counts by type and nonpolio AFP (NPAF) rates in Somalia, 2011–2016. Strengthening AFP surveillance systems is thus seen not just as essential to interrupting poliovirus circulation in areas with ongoing transmission but also for protecting the gains already achieved in places where the disease has been eliminated. Stool specimen adequacy rates assess the timeliness of investigation and the quality of the reverse cold chain system used for poliovirus isolation. Kenya’s AFP surveillance system surpassed the WHO recommended minimum targets for both non-polio AFP rate and stool adequacy during the period studied. Surveillance for cases of acute flaccid paralysis (AFP) is a key strategy adopted for the eradication of polio. This work is written by (a) US Government employee(s) and is in the public domain in the US. Background More than 99% of poliovirus infections are non-paralytic and therefore, not detected by acute flaccid paralysis (AFP) surveillance. Acute flaccid paralysis (AFP) is defined as a sudden onset of paralysis/weakness in any part of the body of a child less than 15 years of age.

Since 2005 the average global child mortality rate has fallen by 3.6% per year1 and Wang et al.1 estimate that the impact of ‘secular trends’, which include technological developments such as vaccines, had the largest impact on reductions in child mortality rates. Among AFP cases reported by VPVs, the mean duration from paralysis onset to notification improved from 5.4 (95% CI, 4.84–5.97) days in 2014 to 3.7 (3.32–4.14) days in 2016 (Table 1). Surveillance for cases of acute flaccid paralysis (AFP) is a key strategy adopted by the Global Polio Eradication Initiative (GPEI) for the eradication of poliomyelitis [1–3]. Once collected, VPVs work closely with the district polio officer to ensure that the specimens are transported in a timely manner to the regional polio laboratory in Nairobi, Kenya, where testing is conducted. Cameroun WORLD - WILD POLIO VIRUS CASES - 2010 577 CASES IN 15 COUNTRIES Pakistan Afghanistan Countries Wild cases 2010 India 25 Afghanistan 12 Angola 16 Pakistan 31 Tajikistan 437 … Health worker awareness on AFP surveillance and active case search should be strengthened in all aspects … Abbreviations: AFP, acute flaccid paralysis; CI, confidence interval; SD, standard deviation; VPVs, Village Polio Volunteers. Identification of ≥2 nonpolio AFP (NPAFP) cases per 100000 persons aged <15 years is recommended by the World Health Organization (WHO) as a benchmark for surveillance activities in regions with active poliovirus transmission or places at significant risk of outbreaks [8, 9].

The aforementioned factors led to the establishment of the Village Polio Volunteers (VPV) program in September 2013. Potential conflicts of interest. Abbreviations: AFP, acute flaccid paralysis; WPV, wild poliovirus. All authors: No reported conflicts of interest. 7. AFP surveillance in Pakistan collected data on 43,301 NPAFP cases between January 2003 and June 2016, with an average annual rate increasing from 4.3 to 11.4 NPAFP per 100,000 children under the age of 5 years from 2003 to 2016.

Flanagan P, O’Lorcain P, Cotter S, et al. Of the 546 AFP cases reported in 2013, 194 (36%) were subsequently confirmed to be WPV cases. A crucial step in the investigation is the collection of 2 stool specimens from the case patients ≥24 hours apart. With extensive ES and continued circulation of polioviruses, Pakistan presents a unique opportunity to quantify the impact of … Duration from Paralysis Onset to Notification of Acute Flaccid Paralysis Cases by Year and Reporting Source, Somalia, 2014–2016. Explore the difference between the single-chamber and dual-chamber microbial electrosynthesis for biogas production performance. They again accounted for the highest proportion of AFP cases reported in 2016 when compared with other reporting sources. 701–716) They were then trained by experienced polio program staff on key strategies for polio eradication, including AFP surveillance, and assigned to work in the communities from which they were recruited. The number of cases reported each year is used as an indicator of a country's ability to detect polio, even in countries where the disease no longer occurs. Abbreviation: AFP, acute flaccid paralysis. Stool specimen adequacy rates were consistently >95% during 2011–2016 except in 2013, when the rate dropped to 86.8%.

NPAFP rates decreased from levels during the outbreak to 4.8 and 5.3 cases per 100000 persons aged <15 years during 2015 and 2016, respectively, but remained significantly above preoutbreak reporting levels. By 2014, however, VPVs were responsible for reporting approximately a quarter of all AFP cases, comparable to other major reporting sources, such as public healthcare facilities (24%) and regular polio program staff (29%). These NPAFP rates were derived from AFP cases from which neither wild nor vaccine-derived polioviruses were isolated. This article focuses on the contributions of VPVs to strengthening poliovirus surveillance in Somalia by assessing the impact of their activities on key AFP surveillance indicators. ; EIS officer, Centers for Disease Control and Prevention.
