Assessment of the impact of integrated disease surveillance and response system on surveillance management at healthcare facilities in Pakistan.

Background: Disease surveillance is very crucial especially in high vulnerability settings like Pakistan. However, surveillance and outbreak response management are still evolving in the country and research studies are needed to assess the existing system. Aim: To assess the impact of integrated disease surveillance and response system (IDSRS) implemented by the provincial government to strengthen infectious disease surveillance and reporting in 6 districts of Pakistan in 2016. Methods: A baseline cross-sectional assessment of health facilities and the healthcare workforce was conducted in 2016 to identify needs and gaps in public sector health facilities and the health system of 6 selected districts of Khyber Pakhtunkhwa Province, Pakistan. This was followed by a 2018 endline survey of the same facilities using the same variables. Results: Overall, there was improvement in district management and facility level performance (χ2 (1, 314) = 21.19, P < 0.001, V = 0.26). District level management improved significantly in areas with relatively lower Gross Domestic Product (GDP)? χ2(1, 154) = 30.41, P <0.001, V = 0.44). Facilitation domain variables improved in the lower GDP districts (χ2 (1, 74) = 5.76, P = 0.016, V = 0.28) and showed counterintuitive deterioration (χ2 (1, 74) = 4.80, P = 0.028, V = 0.25) in relatively higher GDP areas. Conclusion: IDSRS is effective in improving surveillance and response systems, however, its effectiveness appears to depend on locale-specific economies and can be enhanced by modifying the implementation approach. Better empowerment of the local workforce can contribute to such improvement.

Public management of public healthcare under the COVID-19 outbreak: experience of Ukraine.

OBJECTIVE: Aim: The research is aimed to study certain aspects and experience of functioning of the Ukrainian Public Healthcare public management mechanisms during an outbreak of the acute respiratory disease COVID19. PATIENTS AND METHODS: Materials and Methods: The studied materials include personal observations and accumulated practical material, as well as generalization of the collected data and their empirical treatment, conducted by the scientists, according to the present legislation requirements. The study was held using general scientific methods, including observation, description of results, specification and statistical data generalization. CONCLUSION: Conclusions: Generalization, arrangement and analysis of the Ukrainian experience of the Public Healthcare public management during the outbreak of the acute respiratory disease COVID19, provides exchange of experience between all subjects of the process. This helps to produce certain practical decisions, aimed at effective responding of the state healthcare system onto management of the COVID19 outbreak. Such activities are also directed at detection of flaws in the whole system, with their subsequent correction, and elimination or neutralization of possible negative outcomes. To adopt the priority activity directions within public relations, which make the subject of the study, the authors have studied a complex of activities against spread of the COVID19 in 2019-2020. These activities include issues, related to prompt responding onto the infection spread and approving quick professional decisions; fulfilling epidemiological supervision and introducing anti-epidemic activities; providing diagnostics, and accessibility of the safe and high-quality vaccine.

2022 Polio outbreak, Rockland County, NY: Cost evaluation of strategies to prevent future outbreaks of vaccine-preventable diseases.

In 1994, the World Health Organization Region of the Americas was declared polio-free. In July 2022, a confirmed case of paralytic polio in an unvaccinated adult resident of Rockland County, New York was reported by the New York State Department of Health (NYSDOH) and Rockland County Department of Health (RCDOH). While only one case was identified, a single case of paralytic polio represents a public health emergency in the United States. The patient's county of residence was identified to have low vaccination coverage indicating that the community was at risk for additional cases. Disease outbreaks are resource-intensive and incur high costs to the patient, local health departments, and to society. These costs are potentially avoidable for vaccine-preventable diseases and thus, highlight the urgency to not only interrupt transmission but to prevent future vaccine-preventable disease outbreaks by improving vaccination coverage. Following case confirmation, an investigation and response was initiated by NYSDOH, along with local health departments and the Centers for Disease Control and Prevention (CDC). After the initial investigation and response, collaborative efforts to mitigate risk and strengthen routine immunization continued, which included provider outreach and immunization record assessments of Head Start and licensed childcare facilities (primarily those with missing or incomplete required vaccination coverage reports from the previous year) in Rockland County. We estimated the costs of (1) provider outreach and (2) childcare and pre-kindergarten immunization record assessments of select licensed childcare and Head Start facilities in Rockland County. The total labor cost incurred for these activities was $138,514 with a total of 2,555 h incurred. Often there are unique opportunities in the midst of an outbreak for public health to implement activities to proactively address low vaccination and strengthen vaccination coverage and possibly prevent future outbreaks. Understanding the cost of these activities might help inform future outbreak planning.

Preparing healthcare facilities in sub-Saharan Africa for future outbreaks: insights from a multi-country digital self-assessment of COVID-19 preparedness.

BACKGROUND: Despite previous experience with epidemics, African healthcare systems were inadequately prepared and substantially impacted by the coronavirus disease 2019 (COVID-19) pandemic. Limited information about the level of COVID-19 preparedness of healthcare facilities in Africa hampers policy decision-making to fight future outbreaks in the region, while maintaining essential healthcare services running. METHODS: Between May-November 2020, we performed a survey study with SafeCare4Covid - a free digital self-assessment application - to evaluate the COVID-19 preparedness of healthcare facilities in Africa following World Health Organization guidelines. The tool assessed (i) COVID-19-related capabilities with 31 questions; and (ii) availability of essential medical supplies with a 23-supplies checklist. Tailored quality improvement plans were provided after assessments. Information about facilities' location, type, and ownership was also collected. RESULTS: Four hundred seventy-one facilities in 11 African countries completed the capability assessment; 412 also completed the supplies checklist. The average capability score on a scale of 0-100 (n=471) was 58.0 (interquartile range 40.0-76.0), and the average supplies score (n=412) was 61.6 (39.0-83.0). Both scores were significantly lower in rural (capability score, mean 53.6 [95%CI:50.3-57.0]/supplies score, 59.1 [55.5-62.8]) versus urban facilities (capability score, 65.2 [61.7-68.7]/supplies score, 70.7 [67.2-74.1]) (P<0.0001 for both comparisons). Likewise, lower scores were found for public versus private clinics, and for primary healthcare centres versus hospitals. Guidelines for triage and isolation, clinical management of COVID-19, staff mental support, and contact tracing forms were largely missing. Handwashing stations were partially equipped in 33% of facilities. The most missing medical supply was COVID-19 specimen collection material (71%), while 43% of facilities did not have N95/FFP2 respirators and 19% lacked medical masks. CONCLUSIONS: A large proportion of public and private African facilities providing basic healthcare in rural areas, lacked fundamental COVID-19-related capabilities and life-saving personal protective equipment. Decentralization of epidemic preparedness efforts in these settings is warranted to protect healthcare workers and patients alike in future epidemics. Digital tools are of great value to timely measure and improve epidemic preparedness of healthcare facilities, inform decision-making, create a more stakeholder-broad approach and increase health-system resilience for future disease outbreaks.

Cost effectiveness of preemptive school closures to mitigate pandemic influenza outbreaks of differing severity in the United States.

BACKGROUND: Nonpharmaceutical interventions (NPIs) may be considered as part of national pandemic preparedness as a first line defense against influenza pandemics. Preemptive school closures (PSCs) are an NPI reserved for severe pandemics and are highly effective in slowing influenza spread but have unintended consequences. METHODS: We used results of simulated PSC impacts for a 1957-like pandemic (i.e., an influenza pandemic with a high case fatality rate) to estimate population health impacts and quantify PSC costs at the national level using three geographical scales, four closure durations, and three dismissal decision criteria (i.e., the number of cases detected to trigger closures). At the Chicago regional level, we also used results from simulated 1957-like, 1968-like, and 2009-like pandemics. Our net estimated economic impacts resulted from educational productivity costs plus loss of income associated with providing childcare during closures after netting out productivity gains from averted influenza illness based on the number of cases and deaths for each mitigation strategy. RESULTS: For the 1957-like, national-level model, estimated net PSC costs and averted cases ranged from $7.5 billion (2016 USD) averting 14.5 million cases for two-week, community-level closures to $97 billion averting 47 million cases for 12-week, county-level closures. We found that 2-week school-by-school PSCs had the lowest cost per discounted life-year gained compared to county-wide or school district-wide closures for both the national and Chicago regional-level analyses of all pandemics. The feasibility of spatiotemporally precise triggering is questionable for most locales. Theoretically, this would be an attractive early option to allow more time to assess transmissibility and severity of a novel influenza virus. However, we also found that county-wide PSCs of longer durations (8 to 12 weeks) could avert the most cases (31-47 million) and deaths (105,000-156,000); however, the net cost would be considerably greater ($88-$103 billion net of averted illness costs) for the national-level, 1957-like analysis. CONCLUSIONS: We found that the net costs per death averted ($180,000-$4.2 million) for the national-level, 1957-like scenarios were generally less than the range of values recommended for regulatory impact analyses ($4.6 to 15.0 million). This suggests that the economic benefits of national-level PSC strategies could exceed the costs of these interventions during future pandemics with highly transmissible strains with high case fatality rates. In contrast, the PSC outcomes for regional models of the 1968-like and 2009-like pandemics were less likely to be cost effective; more targeted and shorter duration closures would be recommended for these pandemics.

Cost-effectiveness analysis of COVID-19 intervention policies using a mathematical model: an optimal control approach.

COVID-19 is an infectious disease that causes millions of deaths worldwide, and it is the principal leading cause of morbidity and mortality in all nations. Although the governments of developed and developing countries are enforcing their universal control strategies, more precise and cost-effective single or combination interventions are required to control COVID-19 outbreaks. Using proper optimal control strategies with appropriate cost-effectiveness analysis is important to simulate, examine, and forecast the COVID-19 transmission phase. In this study, we developed a COVID-19 mathematical model and considered two important features including direct link between vaccination and latently population, and practical healthcare cost by separation of infections into Mild and Critical cases. We derived basic reproduction numbers and performed mesh and contour plots to explore the impact of different parameters on COVID-19 dynamics. Our model fitted and calibrated with number of cases of the COVID-19 data in Bangladesh as a case study to determine the optimal combinations of interventions for particular scenarios. We evaluated the cost-effectiveness of varying single and combinations of three intervention strategies, including transmission control, treatment, and vaccination, all within the optimal control framework of the single-intervention policies; enhanced transmission control is the most cost-effective and prompt in declining the COVID-19 cases in Bangladesh. Our finding recommends that a three-intervention strategy that integrates transmission control, treatment, and vaccination is the most cost-effective compared to single and double intervention techniques and potentially reduce the overall infections. Other policies can be implemented to control COVID-19 depending on the accessibility of funds and policymakers' judgments.

Ebola virus disease in children: epidemiology, pathogenesis, management, and prevention.

Ebola disease is a severe disease with extremely high case-fatality rates ranging from 28-100%. Observations made during the 2013-2016 West African epidemic improved our understanding of the clinical course of Ebola disease and accelerated the study of therapeutic and preventative strategies. The epidemic also highlighted the unique challenges associated with providing optimal care for children during Ebola disease outbreaks. In this review, we outline current understanding of Ebola disease epidemiology, pathogenesis, management, and prevention, highlighting data pertinent to the care of children. IMPACT: In this review, we summarize recent advancements in our understanding of Ebola disease epidemiology, clinical presentation, and therapeutic and preventative strategies. We highlight recent data pertinent to the care of children and pregnant women and identify research gaps for this important emerging viral infection in children.

Epidemiological features of SARS-CoV-2 Omicron infection under new control strategy: a cross-sectional study of the outbreak since December 2022 in Sichuan, China.

BACKGROUND: A major shift in the "dynamic zero-COVID" policy was announced by China's National Health Commission on December 7, 2022, and the subsequent immediate large-scale outbreak of SARS-CoV-2 infections in the entire country has caused worldwide concern. This observational cross-sectional study aimed to describe the epidemiological characteristics of this outbreak in Sichuan, China. METHODS: All data were self-reported online by volunteers. We described the epidemic by characterizing the infection, symptoms, clinical duration, severity, spatiotemporal clustering, and dynamic features of the disease. Prevalence ratio (PR), Odds ratios (ORs) and adjusted ORs were calculated to analyze the associations between risk factors and infection and the associations of risk factors with clinical severity using log-binomial and multivariable logistic regression models; 95% confidence intervals (CIs) and Wald test results were reported. The prevalence rates and clinical severity among different subgroups were compared using the Chi-square and trend Chi-square tests. RESULTS: Between January 6 and 12, 2023, 138,073 volunteers were enrolled in this survey, and 102,645 were infected with COVID-19, holding a prevalence rate of 74.34%; the proportion of asymptomatic infections was 1.58%. Log-binomial regression revealed that the risk of infection increased among those living in urban areas. Multivariable logistic regression analysis showed that female sex, chronic diseases, older age and the fewer doses of vaccine received were associated with an increased risk of severe clinical outcomes after infection. We estimated the mean reproduction number during this pandemic was 1.83. The highest time-dependent reproduction number was 4.15; this number decreased below 1 after 11 days from December 7, 2022. Temporal trends revealed a single peak curve with a plateau pattern of incidence during the outbreak, whereas spatiotemporal clustering analysis showed that the onset in 21 cities in the Sichuan province had four-wave peaks. CONCLUSIONS: The peak of the first wave of Omicron infection in Sichuan Province had passed and could be considered a snapshot of China under the new control strategy. There were significant increases in the risk of severe clinical outcomes after infection among females, with chronic diseases, and the elderly. The vaccines have been effective in reducing poor clinical outcomes.

Lost in translation: the importance of addressing language inequities in global health security.

Language inequities in global health stem from colonial legacies, and global health security is no exception. The International Health Regulations (IHRs), a legally binding framework published by the WHO, lay the foundation for global health security and state the roles and responsibilities States Parties are compelled to follow to improve their capabilities to prevent, detect and respond to potential public health emergencies of international concern. It includes the submission of a mandatory status report that assesses a nation's implementation of IHRs. Known as the States Party Self-Assessment Annual Report (SPAR) tool, WHO has made its guidance document available in all six WHO official languages (Arabic, Chinese, English, French, Russian and Spanish). The Republic of Iraq (Iraq) experienced significant challenges during the completion and submission of the 2022 SPAR. This experience demonstrated that translation of English materials to other languages, such as Arabic, is not prioritised and further underscored how scoring of a country's global health security capacities can be significantly impacted by users' ability to read and comprehend the materials in English. Not only can this lead to inaccurate SPAR scoring, but it can also lead to the improper allocation of resources and prioritisation of policy developments and/or amendments. By drawing attention to this issue, we aim to inform and advocate for global health security decision-makers to consider opportunities for increasing inclusion and accessibility, especially for requirements under legally binding international instruments.

Scabies outbreak management in refugee/migrant camps in Europe 2014-2017: a retrospective qualitative interview study of healthcare staff experiences and perspectives.

OBJECTIVES: Provide insights into the experiences and perspectives of healthcare staff who treated scabies or managed outbreaks in formal and informal refugee/migrant camps in Europe 2014-2017. DESIGN: Retrospective qualitative study using semistructured telephone interviews and framework analysis. Recruitment was done primarily through online networks of healthcare staff involved in medical care in refugee/migrant settings. SETTING: Formal and informal refugee/migrant camps in Europe 2014-2017. PARTICIPANTS: Twelve participants (four doctors, four nurses, three allied health workers, one medical student) who had worked in camps (six in informal camps, nine in formal ones) across 15 locations within seven European countries (Greece, Serbia, Macedonia, Turkey, France, the Netherlands, Belgium). RESULTS: Participants reported that in camps they had worked, scabies diagnosis was primarily clinical (without dermatoscopy), and treatment and outbreak management varied highly. Seven stated scabicides were provided, while five reported that only symptomatic management was offered. They described camps as difficult places to work, with poor living standards for residents. Key perceived barriers to scabies control were (1) lack of water, sanitation and hygiene, specifically: absent/limited showers (difficult to wash off topical scabicides), and inability to wash clothes and bedding (may have increased transmission/reinfestation); (2) social factors: language, stigma, treatment non-compliance and mobility (interfering with contact tracing and follow-up treatments); (3) healthcare factors: scabicide shortages and diversity, lack of examination privacy and staff inexperience; (4) organisational factors: overcrowding, ineffective interorganisational coordination, and lack of support and maltreatment by state authorities (eg, not providing basic facilities, obstruction of self-care by camp residents and non-governmental organisation (NGO) aid). CONCLUSIONS: We recommend development of accessible scabies guidelines for camps, use of consensus diagnostic criteria and oral ivermectin mass treatments. In addition, as much of the work described was by small, volunteer-staffed NGOs, we in the wider healthcare community should reflect how to better support such initiatives and those they serve.

Socioecological systems analysis of potential factors for cholera outbreaks and assessment of health system's readiness to detect and respond in Ilemela and Nkasi districts, Tanzania.

BACKGROUND: Cholera outbreaks are a recurrent issue in Tanzania, with Ilemela and Nkasi districts being particulary affected. The objective of this study was to conduct a socio-ecological system (SES) analysis of cholera outbreaks in these districts, identifying potential factors and assessing the preparedness for cholera prevention and control. METHODS: A cross-sectional study was carried out in Ilemela and Nkasi districts of Mwanza and Rukwa regions, respectively in Tanzania between September and October 2021. A SES framework analysis was applied to identify potential factors associated with cholera outbreaks and assess the readiness of the districts to cholera prevention and control. RESULTS: Ilemela is characterised by urban and peri-urban ecosystems while Nkasi is mainly rural. Cholera was reported to disproportionately affect people living along the shores of Lake Victoria in Ilemela and Lake Tanganyika in Nkasi, particularly fishermen and women involved infish trading. The main potential factors identified for cholera outbreaks included defecation in the shallow ends and along the edges of lakes, open defecation, bathing/swimming in contaminated waters and improper waste disposal. The preparedness of both districts for cholera prevention and response was found to be inadequate due to limited laboratory capacity, insufficient human resources, and budget constraints. CONCLUSION: People of Ilemela and Nkasi districts remain at significant risk of recurrent cholera outbreaks and the capacity of the districts to detect the disease is limited. Urgent preventive measures, such as conducting considerable community awareness campaigns on personal hygiene and environmental sanitation are needed to alleviate the disease burden and reduce future cholera outbreaks.

Assessment of Knowledge, Perceptions, and Attitudes During the Global Mpox Outbreak in June 2022: A Cross-Sectional Study From the United Arab Emirates.

Objectives: To examine knowledge, worry, anxiety, and vaccine acceptance for mpox among UAE adults. Methods: An online survey, advertised on academic and social media platform in June 2022 collected data from 959 participants (aged 18 and above) on mpox beliefs, risks, knowledge, worry, anxiety, COVID-19 infection, vaccination, and willingness to receive the mpox vaccine. Bivariate and logistic regression analysis identified associations and predictors between variables. Results: 56% had optimal knowledge of mpox transmission and symptoms. 54% were worried, and 27% experienced anxiety related to the outbreak. Knowledge scores were higher among women, healthcare workers, and those with reliable information sources. High perceived infection risk, changes in precautionary measures, and belief in difficult treatment predicted more worry and anxiety. Higher worry and two or more doses of the COVID-19 vaccine predicted higher likelihood of taking the mpox vaccine. Conclusion: The UAE population showed low knowledge and high worry and anxiety during the global mpox outbreak. Increasing public awareness through targeted educational campaigns is vital. Promoting better understanding of infectious diseases, addressing concerns, and encouraging vaccine uptake can prepare for future outbreaks.

Assessment of the readiness and response toward the dengue fever outbreak (2019) in Sudan: a qualitative exploration.

BACKGROUND: Dengue fever (DF) is a mosquito-borne viral disease transmitted by Aedes mosquito species and has been considered a major public health problem in Kassala State for tens of years. This study aimed to assess the level of readiness and response toward the 2019 dengue fever outbreak in Kassala at the state and community levels. METHODS: This exploratory cross-sectional study was conducted in Kassala State, Sudan, from January to March 2020. The researcher conducted interviews with the key respondents at the state level to assess the level of readiness and response and to reflect the capacity of institutions-public health authorities, health systems, and emergency response bodies. RESULTS: The surveillance system reported 3961 DF cases in Kassala State, representing 93.5% of the total cases in Sudan between August 2019 and January 2020. This outbreak was identified by passive surveillance, 51 samples were tested during the outbreak period, and private clinics and labs were not included in the surveillance system. According to the WHO checklist of outbreak readiness and response, Kassala's surveillance system and public health laboratory received the lowest scores. CONCLUSIONS: The study concludes that outbreak readiness and response could be considered below standards, mainly in the surveillance system and laboratory diagnostic facilities, due to the absence of intersectoral collaboration with a regulatory framework in terms of financial and operational participation.

The cost of public health interventions to respond to the 10th Ebola outbreak in the Democratic Republic of the Congo.

The 10th Ebola virus disease (EVD) outbreak in the Democratic Republic of the Congo (DRC) drew substantial attention from the international community, which in turn invested more than US$1 billion in EVD control over two years (2018-2020). This is the first EVD outbreak to take place in a conflict area, which led to a shift in strategy from a pure public health response (PHR) to a multisectoral humanitarian response. A wide range of disease control and mitigation activities were implemented and were outlined in the five budgeted Strategic Response Plans used throughout the 26 months. This study used the budget/expenditure and output indicators for disease control and mitigation interventions compiled by the government of DRC and development and humanitarian partners to estimate unit costs of key Ebola control interventions. Of all the investment in EVD control, 68% was spent on PHR. The remaining 32% covered security, community support interventions for the PHR. The disbursement for the public health pillar was distributed as follows: (1) coordination (18.8%), (2), clinical management of EVD cases (18.4%), (3) surveillance and vaccination (15.9%), (4) infection prevention and control/WASH (13.8%) and (5) risk communication (13.7%). The unit costs of key EVD control interventions were as follows: US$66 182 for maintaining a rapid response team per month, US$4435 for contact tracing and surveillance per identified EVD case, US$1464 for EVD treatment per case, US$59.4 per EVD laboratory test, US$120.7 per vaccinated individual against EVD and US$175.0 for mental health and psychosocial support per beneficiary. The estimated unit costs of key EVD disease control interventions provide crucial information for future infectious disease control planning and budgeting, as well as prioritisation of disease control interventions.

Increasing Equity in the Transnational Allocation of Vaccines Against Emerging Pathogens: A Multi-Modal Approach.

This article proposes the adoption of a multi-modal system for allocating vaccine doses during large transnational outbreaks of infectious diseases. The chosen allocative criteria (public health need; country-income level; qualification through funding; and, subsidiarily, a modified lottery system) are adapted from a current embodiment of allocative multi-modality outside the context of public health: the New York City Marathon.

Health Economic Analysis of Antiviral Drugs in the Global Polio Eradication Endgame.

BACKGROUND: Polio antiviral drugs (PAVDs) may provide a critical tool in the eradication endgame by stopping poliovirus infections in immunodeficient individuals who may not clear the virus without therapeutic intervention. Although prolonged/chronic poliovirus excreters are rare, they represent a source of poliovirus reintroduction into the general population. Prior studies that assumed the successful cessation of all oral poliovirus vaccine (OPV) use estimated the potential upper bound of the incremental net benefits (INBs) of resource investments in research and development of PAVDs. However, delays in polio eradication, OPV cessation, and the development of PAVDs necessitate an updated economic analysis to reevaluate the costs and benefits of further investments in PAVDs. METHODS: Using a global integrated model of polio transmission, immunity, vaccine dynamics, risks, and economics, we explore the risks of reintroduction of polio transmission due to immunodeficiency-related vaccine-derived poliovirus (iVDPV) excreters and reevaluate the upper bound of the INBs of PAVDs. RESULTS: Under the current conditions, for which the use of OPV will likely continue for the foreseeable future, even with successful eradication of type 1 wild poliovirus by the end of 2023 and continued use of Sabin OPV for outbreak response, we estimate an upper bound INB of 60 million US$2019. With >100 million US$2019 already invested in PAVD development and with the introduction of novel OPVs that are less likely to revert to neurovirulence, our analysis suggests the expected INBs of PAVDs would not offset their costs. CONCLUSIONS: While PAVDs could play an important role in the polio endgame, their expected economic benefits drop with ongoing OPV use and poliovirus transmissions. However, stakeholders may pursue the development of PAVDs as a desired product regardless of their economic benefits.HighlightsWhile polio antiviral drugs could play an important role in the polio endgame, their expected economic benefits continue to drop with delays in polio eradication and the continued use of oral poliovirus vaccines.The incremental net benefits of investments in polio antiviral drug development and screening for immunodeficiency-related circulating polioviruses are small.Limited global resources are better spent on increasing global population immunity to polioviruses to stop and prevent poliovirus transmission.

Poliovirus outbreak in New York State, August 2022: qualitative assessment of immediate public health responses and priorities for improving vaccine coverage.

In 2022, a case of paralysis was reported in an unvaccinated adult in Rockland County (RC), New York. Genetically linked detections of vaccine-derived poliovirus type 2 (VDPV2) were reported in multiple New York counties, England, Israel, and Canada. The aims of this qualitative study were to: i) review immediate public health responses in New York to assess the challenges in addressing gaps in vaccination coverage; ii) inform a longer-term strategy to improving vaccination coverage in under-vaccinated communities, and iii) collect data to support comparative evaluations of transnational poliovirus outbreaks. Twenty-three semi-structured interviews were conducted with public health professionals, healthcare professionals, and community partners. Results indicate that i) addressing suboptimal vaccination coverage in RC remains a significant challenge after recent disease outbreaks; ii) the poliovirus outbreak was not unexpected and effort should be invested to engage mothers, the key decision-makers on childhood vaccination; iii) healthcare providers (especially paediatricians) received technical support during the outbreak, and may require resources and guidance to effectively contribute to longer-term vaccine engagement strategies; vi) data systems strengthening is required to help track under-vaccinated children. Public health departments should prioritize long-term investments in appropriate communication strategies, countering misinformation, and promoting the importance of the routine immunization schedule.
