Implementation of Acute Flaccid Paralysis Surveillance in Emilia-Romagna, Italy: 2018-2019 analysis

Abstract Problem Acute flaccid paralysis (AFP) active surveillance is the gold standard in polio eradication process. Italy was classified in 2017 at intermediate risk of poliovirus reintroduction based on suboptimal poliovirus surveillance. The aim of this study was to restore an adequate level of AFP surveillance in Emilia-Romagna Region. Description of the Problem The Emilia-Romagna's Reference Centre for AFP surveillance, in collaboration with the regional Public Health Service identified a collaborative network for AFP Surveillance by analysing the 2015-2017 Hospital Discharge Registers in all region's hospitals. The surveillance protocol was reviewed with the development of a computerized system of Active Surveillance-Zero Reporting sent by e-mail to doctors in the network every 15 days since October 2018. The goal was to restore the AFP notification system to meet WHO requirements sensitivity, completeness of case investigation, completeness of follow-up and to monitor the active surveillance program adherence. Results The active surveillance network was composed by 49 doctors from both hospital administrations and clinical wards from 4 University Hospitals and 7 Local Health Authorities throughout the region. By the end of 2019, the mean response to each e-mail was 48.5% (SD 7.5%); 7 AFP cases have been reported; 85.7% received a full clinical and virological investigation and 83.3% completed the 60 day's follow-up. The final diagnosis of the cases was: 3 Guillain-Barre, 1 transient polyneuritis after HAV vaccination, 1 neuromyopathy from chronic disease, 1 acute myelitis in patient with DADA2. In 2 cases the paralysis persisted after 60 days. Lessons In 2019, the active surveillance system reached sensitivity, completeness of case investigation and follow-up required. Intervention had no expenses, is easily reproducible, created a direct collaboration between clinical colleagues in the network and the reference center which restored adherence to AFP surveillance. Key messages This work proposes how to improve AFP surveillance in a setting with low polio risk perception due to the absence of cases. Additionally, it reinforces the importance of direct collaboration/teamwork between institutions, regional reference centres and clinicians.

Abstract Following the 2014 outbreak, active surveillance of the EV-D68 has been implemented in many countries worldwide. Despite subsequent EV-D68 outbreaks (2014 and 2016) reported in many areas, EV-D68 circulation remains largely unexplored in Africa except in Senegal, where low levels of EV-D68 circulation were first noted during the 2014 outbreak. Here we investigate subsequent epidemiology of EV-D68 in Senegal from June to September 2016 by screening respiratory specimens from ILI and stool from AFP surveillance. EV-D68 was detected in 7.4% (44/596) of patients; 40 with ILI and 4 with AFP. EV-D68 detection was significantly more common in children under 5 years (56.8%, p = 0.016). All EV-D68 strains detected belonged to the newly defined subclade B3. This study provides the first evidence of EV-D68 B3 subclade circulation in Africa from patients with ILI and AFP during a 2016 outbreak in Senegal. Enhanced surveillance of EV-D68 is needed to better understand the epidemiology of EV-D68 in Africa.

AbstractPoliomyelitis was a disease feared worldwide, striking suddenly and paralysing mainly children for life. Monitoring of suspected cases of poliomyelitis is carried out with Acute Flaccid Paralysis (AFP) surveillance in Turkey. This study examines national data of AFP surveillance and the epidemiology of enteroviruses (EV) in Turkey from 2000 to 2019 and gives an overview of the detected serotypes of EVs. A total of 13,640 samples collected from patients with 5216 AFP pre-diagnosed cases (2 samples from each patient) and 3,208 contacts, during a 20-year period (2000–2019) were investigated. All isolated polioviruses were tested for their wild or vaccine origin according to the WHO recommended protocol by PCR and sequencing analysis were performed. Enterovirus positivity was detected in a total of 915 cases, which were identified as 204 Sabin-like polio virus (SLPV) and 711 non-polio enterovirus (NPEV). Of the 204 SLPV, 141 (69.1%) AFP were detected in patients and 63 (30.9%) were detected in samples taken from their contacts. Of the 711 NPEVs, 516 (72.5%) were from AFP cases and 195 (27.5%) were detected in samples taken from their contacts. It is concluded that the reason for the higher detection rate of NPEV in samples from AFP pre-diagnosed cases is attributed to the polio vaccination rates reaching 97% between 2008 and 2019 in Turkey. The most frequently detected NPEV serotypes were Coxackie A24, B3, and Echo 30. This retrospective study is the first comprehensive study in Turkey to evaluate the results of the AFP surveillance in the last 20 years.

Abstract IntroductionGlobal Polio Eradication Initiative, GPEI led by the World Health Organization (WHO), helped to develop standard acute flaccid paralysis surveillance (AFP) system worldwide, including Bangladesh, which comprises infrastructure, knowledge, expertise, funding, technical assistance, and trained personnel. AFP surveillance can complement any disease surveillance systems, and many countries are now utilizing these polio surveillance assets for monitoring other vaccine-preventable diseases. This paper outlines how AFP surveillance has evolved in Bangladesh over time, its success and challenging factors, and its potential to accomplish other health goals.MethodologyThis mixed-method study includes a grey literature review, a survey for quantitative and qualitative information on barriers and facilitators, and Key Informant Interviews (KIIs) to gather relevant in-depth information on AFP surveillance in Bangladesh. Grey literature was collected online and paper documentation from different stakeholders. Online and in-person surveys were conducted in six divisions of Bangladesh, including Dhaka, Rajshahi, Rangpur, Chittagong, Sylhet, and Khulna, to map tacit knowledge ideas, approaches, and experiences. KIIs were conducted at global, national, and sub-national levels. Data were then combined on focused emerging themes, including history, challenges, and successes of the AFP surveillance system in Bangladesh.ResultsAFP surveillance in Bangladesh was first introduced in 1990 at the district and Upazila level major hospitals. High population growth, low performance, hard-to-reach areas, and groups of people residing in risky zones were major challenges to implementing this surveillance system. Surveillance was gradually enriched by establishing certification standards and community-based AFP surveillance and improved Surveillance Immunization Medical Officer (SIMO) network activities, laboratory activities, and proper monitoring and evaluation. In Bangladesh, a national disease surveillance system and a laboratory are now being used for multiple diseases, including polio, measles, Japanese Encephalitis, Neonatal Tetanus etc.ConclusionIn Bangladesh, it is evident that the AFP surveillance system is supporting the health system more broadly by building knowledge, experience, and assets and forming a strong platform for other health programs. In addition, its strengths can be leveraged for combating new and emerging diseases like COVID-19. However, the sustainability of the AFP surveillance in Bangladesh still needs collaborative support from partners, mainly technical assistance.

Background: The State of Azad Jammu & Kashmir (AJ&K) is polio free since October 2000.The objectives of our study is to review of existing Acute Flaccid Paralysis Surveillance System in Azad Jammu &Kashmir, identify the strong & weak points of the existing system and suggest course of action for efficient performance of the existing system. Methods: This qualitative & quantitative evaluation was conducted at Provincial Disease Surveillance &Response Unit (PDSRU) Muzaffarabad Azad Jammu & Kashmir during March -April 2019. The database of AFP cases during 2018 was reviewed and relevant stakeholder's interviews were conducted consulting guidelines formulated by the Centre for Disease Control & prevention(CDC) in 2001 for Evaluating Public Health Surveillance Systems. Results: In 2018, a total of 265 AFP cases were registered. The mean age was 65 months (range 01 - 180 months). 59 % (n=157) were male children. 58% of cases were under 05 year's age. Standardized case definition and data format with simple information flow was found. System was flexible enough to incorporate measles and neonatal tetanus cases since 2009. Data quality was excellent (100% zero and monthly reports). A close coordination was observed amongst all relevant stakeholders. Sensitivity was 200%. No polio case was identified and therefore, PPV was zero. Majority of cases were reported by public sector (93%).Sufficient financial as well as skilled human resources were available and hence system found stable. Timeliness of reporting found 90%. Conclusion: The performance of AFP surveillance system in AJ&K is up to the mark. However, there is constant threat of reintroduction of polio virus from adjacent area of Punjab & Khyber Pakhtunkhwa provinces. Highly vigilant AFP surveillance system with capacity of rapid response is the solution. Furthermore, it is vital to sustain the AFP Surveillance till the goal of global polio eradication is achieved.

Abstract Background: Nigeria and indeed, entire Africa has been certified free of Wild Polio Virus (WPV) in 2020. However, the continent is still at risk of importation of WPV, especially in states like Sokoto in Nigeria, which has an international border. Furthermore, due to low immunity in some communities in Sokoto, outbreaks of the circulating Vaccine Derived Polio Virus (cVDPV) occur. Therefore, this paper evaluates the Acute Flaccid Paralysis (AFP) surveillance indicators in Sokoto state, Nigeria. Methods: This retrospective study was an analysis of routinely collected AFP surveillance data between 2012 and 2019 by the Sokoto state surveillance network. We assessed the Sokoto state AFP surveillance system using the AFP surveillance performance indicators. We performed all analyses using Microsoft Excel 2019.Results: Cumulatively, 3001 Acute Flaccid Paralysis (AFP) cases were reported over the evaluation period, out of which 1692 (56.4%) were males, and 2478 (82.4%) were below five years. More than half, 1773 (59.1%) had a fever at the beginning of the disease, and 1911 (63.7%) had asymmetric paralysis. The non-polio AFP rate (9.1 to 23.5%) and stool adequacy rate (92.5 to 100%) indicate high sensitivity. The proportion of cases that had stool samples collected early, timely transported to the laboratory and arrived at the laboratory in optimal condition were all above the World Health Organization (WHO) minimum standard of 80%. There was inadequate profile documentation of some suspected cases.Conclusions: Sokoto State has exceeded the WHO minimum standards in most of the AFP surveillance indicators. The performance of the system is sufficient enough to detect any reintroduction of WPV into the state. However, there is a need for improvement in data quality.

Here we analyzed six years of acute flaccid paralysis (AFP) surveillance, from 2015 to 2020, of 10 countries linked to the WHO Regional Reference Laboratory, at the Istituto Superiore di Sanità, Italy. The analysis also comprises the polio vaccine coverage available (2015–2019) and enterovirus (EV) identification and typing data. Centralized Information System for Infectious Diseases and Laboratory Data Management System databases were used to obtain data on AFP indicators and laboratory performance and countries’ vaccine coverage from 2015 to 2019. EV isolation, identification, and typing were performed by each country according to WHO protocols. Overall, a general AFP underreporting was observed. Non-Polio Enterovirus (NPEV) typing showed a high heterogeneity: over the years, several genotypes of coxsackievirus and echovirus have been identified. The polio vaccine coverage, for the data available, differs among countries. This evaluation allows for the collection, for the first time, of data from the countries of the Balkan area regarding AFP surveillance and polio vaccine coverage. The need, for some countries, to enhance the surveillance systems and to promote the polio vaccine uptake, in order to maintain the polio-free status, is evident.

AbstractsRecently, a reverse transcriptase seminested polymerase chain reaction (RT-snPCR) assay was recommended by the WHO for direct detection of enteroviruses from clinical specimen. In this study, we use the assay and its modification to screen acute flaccid paralysis (AFP) samples previously confirmed negative for enteroviruses by the RD-L20B algorithm.Thirty paired stool suspensions collected in 2015 as part of the national AFP surveillance program in different states of Nigeria were analyzed in this study. The samples were previously confirmed negative for enteroviruses by the polio laboratory in accordance with the WHO recommended RD-L20B cell culture based algorithm. Two samples previously confirmed to contain enteroviruses were included as positive controls. All samples were subjected to RNA extraction, and the RT-snPCR assay and its modifications. All amplicons were sequenced and enteroviruses identified using the enterovirus genotyping tool.Overall, amplicons were recovered from the two controls and 50% (15/30) of samples screened. Fourteen were successfully typed of which, 7.1% (1/14), 21.4% (3/14), 64.3% (9/14) and 7.1% (1/14) were EV-A, EV-B, EV-C and a mixture of EV-B and C (EV-C99 and E25), respectively. The two controls were identified as EV-C99 and CV-A1, both EV-Cs. The PV-2 detected had VP1 ILE143. Hence, a vaccine strain.The results of this study showed that about 50% of enterovirus infections (including some Sabin PV2s) are being missed by the RD-L20B cell culture based algorithm. This highlights the value of the RT-snPCR assay and its modifications. The circulation and preponderance of EV-Cs in Nigeria was also confirmed.

The Impact

BACKGROUND Highly sensitive acute flaccid paralysis surveillance (AFP), which include immediate case investigation, and specimen collection are critical for reaching polio global eradication. In Yemen, the Acute Flaccid Paralysis Surveillance System (AFPSS) was launched in 1998 to achieve the polio eradication target. Although Yemen was certified as polio free country in 2009, the protracted war since 2015 put the country at risk for polio re-emergence OBJECTIVE to evaluate the performance of the Yemen AFPSS at both national and governorate levels and to assess the impact of the ongoing war on the performance METHODS Retrospective descriptive analysis was conducted on Yemen secondary AFP surveillance data for the years 2014 (before the war) and 2015-2017 (during the war). Data consisting of all children <15years reported as AFP. AFP surveillance performance was evaluated using WHO-specified AFP surveillance indicators RESULTS At the national level, all indicators were met before and after the war except for the “Lab results received ≤ 28 days” that was unmet since the war erupted. Furthermore, the “Stool specimens arriving at central level ≤3 days” was unmet after the war but only in 2017. At the governorate level, although the “Adequacy” and "Stool specimens arriving at laboratory in good condition” indicators were met before the war in all governorates, the first indicator was unmet in 9 (41%) governorates since the war erupted and the second was unmet in 9 governorates (41%) but only in 2017 CONCLUSIONS Findings showed that some of the AFP indicators was negatively impacted by eruption of the war due to closure of the Sana'a capital airport and postponement of samples during shipment to the reference laboratory under poor storage condition. To ensure rapid detection of any polio cases, improving specimens’ collection, storage, and transportation together with proper and timely specimens' shipment to the reference laboratory should be considered

The Mean

ObjectiveWe evaluated the AFP surveillance system in Oyo State to assessits attributes and determine if it was meeting its set objectives.IntroductionIn September, 2015, Nigeria was delisted from the list of polioendemic countries globally. To be certified polio free, the countrymust attain and maintain certification standard Acute Flaccid Paralysis(AFP) surveillance for additional two-years. In Oyo State, no case ofWild Polio Virus (WPV) has been reported since February, 2009.MethodsWe used the Centre for Disease Control and Prevention updatedguidelines for evaluating public health surveillance system.We conducted a retrospective review of AFP surveillance databetween 1stJanuary, 2008 and 31stDecember, 2014. We conductedin-depth interviews with identified stakeholders. Semi-structuredquestionnaires were administered to Disease Surveillance andNotification Officers (DSNOs) and AFP focal persons. Univariateanalysis was performed by calculating frequencies, means andproportions using Microsoft Excel 2010.ResultsThe case definition of AFP and the tools for reporting are simple.Of the 897 AFP cases detected during the period under review(2008-2014), 20 (2.2%) were laboratory confirmed WPV. Thesensitivity of the system between 2008 and 2014 measured by theAnnualized Non-Polio AFP (NPAFP) rate was consistently abovethe target. of≥2/100,000 population(Mean=3.96, Standard deviation(SD): 0.48). The mean NPAFP rate for underperforming LGAs duringthe review period was 1.6, SD: 0.31. The mean Stool adequacy andTimeliness were 91.43% (SD: 18.3) and 91.3% (SD: 20.3) abovethe target of≥80% respectively. The mean Data quality was 90%(target is≥90; SD: 3.8). Positive Predictive Value (PVP) was 2%(2008 -2009), and 0% in 2010-2014.ConclusionsThe Oyo State AFP surveillance system is simple, flexible,sensitive and meeting its set objectives. However, PVP was low andthe system’s operating conditions are not stable. All the LGAs, at onepoint during the period under review did not meet the NPAFP andNPENT rates. We recommended that more logistic support shouldbe provided for non-performing LGAs to improve case reporting,investigation, and response. DSNOs should be re -sensitized onreverse cold chain, so as to improve the NPENT rate

Terdapat 39 kasus AFP yang disebabkan cVDPV tipe 1 ditemukan di Pulau Madura pada tahun 2005. Virus polio liar tipe 1 hanya ditemukan di pulau Sumatera dan Jawa. Penyebaran Virus polio berhasil dihentikan pada tahun 2006 dan sudah tidak ditemukan lagi hingga tahun 2013. Kesimpulan: Surveilans AFP berbasis laboratorium yang baik berhasil memantau dan mendeteksi sirkulasi virus polio. Peningkatan kinerja surveillance AFP diperlukan untuk membuktikan terhentinya transmisi virus polio sehingga eradikasi polio secara global dapat diraih. Kata kunci: surveilans, laboratorium polio, Acute Flaccid Paralysis Abstract Background: Wild Poliovirus can cause flaccid paralysis and can be prevented by immunization. To monitor wild polio virus transmission, Acute Flaccid Paralysis (AFP) surveillance and laboratory investigations was initiated in 1995 in Indonesia. The last indigenous wild poliovirus found at 1995 in Indonesia. Indonesia still has the threat of imported wild polio viruses from endemic countries and poliovirus mutation from vaccine that can cause paralytic as well as wild poliovirus. The aim of this article is to describe the laboratory-based AFP surveillance in Indonesia from 2003-2013 so that it had led the Indonesia certified for polio free in 2014. Methods: Data analysis performed on AFP cases data from all provinces in Indonesia period of 2013-2014. Data were collected from polio laboratories network in Jakarta, Bandung, Surabaya and the Sub Directorate of Surveillance, Directorate of Surveillance and Health Quarantine, Directorate General of Disease Prevention and Control. Data were analyzed using Microsoft Excel program. Results: 305 paralysis cases were caused by imported type 1 wild poliovirus infection were found in 2005 and 2006. 39 paralysis cases caused by type 1 cVDPV infection were also found on Madura Island in 2005. Type 1 wild polioviruses only found on the Sumatra and Java island. The wild poliovirus transmission was stopped in 2006 and was no longer found until 2013. Conclusion: Good laboratory-based AFP surveillance has been successfully monitoring and detecting the circulation of the poliovirus. Improved AFP surveillance performance is needed to prove cessation of poliovirus transmission so that eradication of poliovirus can be achieved globally.
