Yemen COVID-19 Health Services Pandemic Control Epidemic Response Figures Figure 1 Contribution to the field This manuscript contributes significantly to the understanding of health and health service challenges during the COVID-19 pandemic in Yemen, a region already strained by prolonged conflict. By employing a mixed-method approach that combines data analysis from international and local sources with in-depth interviews, the study addresses critical gaps in current knowledge regarding the pandemic's impact on a fragile health system. The research specifically highlights the importance of multi-sectoral efforts in managing public health emergencies and identifies key challenges such as misinformation, inadequate healthcare infrastructure, and the necessity for specialized epidemic hospitals. In the context of existing literature, this study is among the first to provide a comprehensive analysis of Yemen's health service responses to COVID-19, offering new insights into the specific needs and vulnerabilities of conflict-affected regions during a global pandemic. The findings not only underscore the need for targeted interventions but also contribute to broader discussions on how health systems in fragile states can be strengthened to better withstand public health crises. This work thus advances the field by providing evidence-based recommendations for improving health service delivery in conflict settings, informing both policy and future research initiatives. 1. Introduction Yemen, one of the poorest countries in the Middle East, faces the worst humanitarian crises due to conflict, disease outbreaks, and on top the latest COVID-19 pandemic. More than half the population in Yemen experience poverty and lack access to essential health services [ 1 ]. Moreover, the country’s fragile health system weakened its capacity to effectively detect diseases such as cholera, dengue, and diphtheria, and manage the latest COVID-19 cases [ 2 , 3 ]. This is due to conflict which also increases migration, refugees, and internal displacement of people (IDPs) [ 4 ]. The public sector mainly manages Yemen's health system through local health offices that report to the Ministry of Public Health and Population [ 5 – 7 ]. However, due to a long conflict, the health system has severely deteriorated, and only half of the health facilities are functional [ 5 , 6 , 8 ]. Moreover, the health system is mainly financed through private, out-of-pocket, decreasing the capacity of people to seek health care thus affecting life expectancy and rising child and maternal mortality [ 9 ]. Another major challenge in the health system is the service delivery level due to a shortage of qualified health staff, with only 10 available per 10,000 people [ 3 ]. As a result, urgent improvements in facilities and human resource training are needed [ 10 ]. COVID-19 seriously affected Yemen’s health services where a decline in consultations, surgeries, and child vaccinations was significant due to lockdowns and fear of infections [ 11 ]. Yemen's already fragile health system has struggled to maintain routine primary care, especially maternal and newborn services, due to the focus on urgent food insecurity issues [ 6 ]. Humanitarian agencies face challenges in supporting healthcare delivery due to scheduling and data access [ 12 ]. The first case of COVID-19 in Yemen was confirmed in the Hadhramaut governorate on April 10, 2020 [ 13 , 14 ]. By July 20, 2020, there were 1,610 confirmed cases and 446 deaths with a mortality rate of 27%, five times the global average [ 14 ]. By June 1, 2020, Yemen had experienced four waves of COVID-19 with 11,935 reported cases and 2158 deaths [ 5 ] however, underreporting of cases is most likely due to the low capacity of detecting cases [ 15 ]. In response to the COVID-19 outbreaks in Yemen, the WHO organized early international assistance in collaboration with Yemen’s Ministry of Health and 20 partner organizations [ 11 , 16 ]. However, despite some efforts Yemen did not apply the lockdown needed to mitigate the Spread of COVID-19, mainly due to a lack of good coordination between the government and the people [ 11 ]. Additionally, the authorities in Sana’a refused to collaborate [ 11 ]. The main aim of this study is to assess the impact of COVID-19 on Yemen's already fragile health system. By evaluating the scale of health issues and service challenges linked to the pandemic in Aden City, the study aims to generate evidence that helps policymakers improve interventions and responses toward future outbreaks. 2. Methods 2.1. Study Design and Sampling This is a mixed-method cross-sectional study focused on Aden governorate that incorporated a quantitative and qualitative analysis. The first part of the study includes a review of COVID-19 reports starting from January 2022 to April 2022 from the Ministry of Public Health and Population (MOPHP), UN, WHO, and other governmental documents. The second phase involved in-depth interviews with 22 participants aimed to assess the scope and magnitude of the health and health service challenges related to the pandemic. The final phase of the study included a checklist that highlights the importance of public health measures taken to mitigate the COVID-19 outbreak. Aden was chosen as a study Area since it has a good catchment area and has many COVID-19 cases, is densely populated, diverse, and is relatively safer than other places. Sampling included a quantitative analysis of 134 daily health reports taken from the MoPHP between January 1, 2022, to April 21, 2022, involving a checklist with 32 participants from several sectors, incorporating local communities, religious leaders, governmental and non-governmental organizations, and the health and non-health sectors. Moreover, In-depth interviews were conducted with 22 individuals from governmental institutions, non-governmental organizations, health facilities, and the community, who were selected through snowball sampling based on recommendations from key informants to ensure diverse sectoral representation. 2.2.Data Collection and Analysis Data collection tools were developed, pilot-tested, and refined. Moreover, interviews were conducted in Arabic and recorded, transcribed verbatim in English, and verified for accuracy by multiple reviewers. Data were translated into English, entered in Excel sheets, and categorized using STATA 13 software. Quantitative analysis was performed using SPSS for descriptive statistics and variable associations, while checklists and reports were analyzed in Excel. Also, qualitative data were manually coded in Excel, with subsequent organization and analysis of content transferred from Excel to Word to ensure a logical structure. 3. Results 3.1. Quantitative Findings This section describes the findings of this study based on the results of the summarized reports and data records. Table 1 reflects the demographic characteristics of the reported cases from the National Surveillance System in Yemen between March 2020 - February 2022. The distribution of COVID-19 cases is represented in 8 districts of Aden governorate. The mean age of the cases was 42 years (± 19.8643) with a range (0-110 years). The COVID-19 data reveals a high concentration of cases in Khur Maksar (54%) and Dar-sad (20%), with significant numbers also reported in Ash Shaikh Outhman and Al Mansura. The most affected age group is 30–49 years (31.4%), followed by 18–29 years (20.0%) and 50–65 years (24.0%). Males are more affected than females, with a distribution of 62% and 38%, respectively. Most patients received home care (95.5%), while only a small percentage required hospitalization (4.5%).

Discussion Our results showed many challenges faced by the Yemeni health system in responding to the COVID-19 pandemic, exacerbated by ongoing conflict. Key problems include limited access to healthcare facilities, leakage of medical supplies, and closure of hospitals due to staff infections. These challenges were caused by a lack of coordination response plans and insufficient budgetary resources, which hampered the effectiveness of health authorities in managing the pandemic. Aden City faced additional difficulties; including severe floods that led to increased cholera cases and vector-borne diseases such as malaria, dengue, and chikungunya[ 17 , 18 ]. The shortage of health workers has widened during the pandemic with hospital closures due to staff injury and sickness. Yemen has only ten health staff per 10,000 people, far below the WHO benchmark, and only five physicians per 10,000, compared to 26 in Saudi Arabia and 20 in Oman. General practitioners (GPs) were depended upon as primary emergency care providers, irrespective of their experience, despite facing more obstacles than emergency physicians, negatively impacting patient care [ 19 , 20 ]. In contrast to Yemen, neighboring Gulf countries instance Saudi Arabia and Oman applied advanced technologies such as artificial intelligence, data sciences, and machine learning to understand the complexity of the COVID-19 pandemic [ 21 ]. Oman, despite challenges with a lack of public health professionals and a shortage of risk communication experts, utilized an integrated digital platform for surveillance [ 22 ], while Saudi Arabia, adopted a “whole government” strategy following WHO recommendation, leveraging its prior experience with 2012 MERS outbreak and the establishment of Saudi Center for Disease Control and Prevention (SCDC) to effectively manage the pandemic [ 23 , 24 ]. Yemen's inadequate health infrastructure and fragile health system due to conflict underscore the seriousness of the situation, with underreporting of cases further complicating the assessment of the pandemic's impact [ 21 ]. Various multi-sectorial actions were taken in Yemen to combat COVID-19, with contributions from governmental and non-governmental organizations and international agencies, including efforts in triage, referral, awareness campaigns, and provision of medical supplies. However, delays in coordinating in response and insufficient government support hindered these efforts [ 25 ]. To improve Yemen's health services and infrastructure, policymakers must adopt multi-sectoral action, as seen in Saudia Arabia. This includes rebuilding health facilities, ensuring access to essential services like water and electricity, sanitation, and strengthening primary healthcare services and inter-governorate governance [ 26 – 28 ]. The implementation of an emergency medical services (EMS) plan and multi-sectoral efforts involving the MOPHP, Ministry of Interior, military, and others are crucial for effective disaster response [ 20 , 29 ]. Yemen's laboratory services are also limited, with only six central public health laboratories capable of testing COVID-19 cases [ 30 ] and a shortage of PCR machines and reagents for further case detection [ 31 ]. Community engagement and awareness were identified as key factors in combating COVID-19, but challenges such as denial of the pandemic, vaccine hesitancy, misinformation, and rumors were significant obstacles [ 32 , 33 ]. Our study's findings show several community-related challenges, including a lack of awareness about the importance of protective instructions for COVID-19. One study confirmed our findings that many Yemenis were unaware of the disease or did not believe in it, and the community was generally resistant to lockdown measures[ 29 ]. In contrast, Oman and Saudi Arabia saw more effective community engagement and use of technology in their COVID-19 response. Oman utilized AI interventions such as chatbots for risk assessment and follow-up and maintained strong community partnerships at all levels of the response, including vaccination campaigns [ 22 ]. Saudi Arabia implemented a couple of curfews, activated massive testing, and used social media extensively for awareness campaigns, which helped flatten the epidemiological curve [ 24 , 34 , 35 ]. Studies in Saudi Arabia also highlighted differences in COVID-19 knowledge between males and females, with women showing better knowledge and practices towards COVID-19 than men [ 36 ]. Concerns among healthcare workers (HCWs) regarding COVID-19 were also noted, with studies identifying predictors of those with the highest levels of concern [ 37 ]. In our study, as emphasized in the Appendix ( Supplementary Table. 4 ), almost all participants recognized the importance of implementing containment measures. A previous study identified gaps in vaccination knowledge, that may affect vaccine uptake [ 33 ]. In low-income countries like Uganda, continuous professional education for health workers is recommended to improve knowledge, prevent negative attitudes, and promote positive preventive practices [ 38 ]. A study in Iran highlights the need to address global knowledge gaps, considering political, economic, social, and cultural factors [ 39 ]. The fragile health system in Yemen, characterized by limited capacity to detect and manage COVID-19 cases, has led to a high mortality rate, exceeding five times the global average [ 40 ]. The high mortality among those under 60 years coupled with inadequate healthcare infrastructures, suggests a high probability of misdiagnoses and underestimation of new cases. Geospatial analysis of burial activity in Aden during the pandemic indicates that the actual impact of COVID-19 may be significantly underreported [ 41 ]. On March 16, 2020, the Yemeni government founded the high intersectoral committee to coordinate the COVID-19 response, involving all related ministries and security authorities [ 31 ]. However, the lack of research on population-specific response and health system strengthening due to ongoing war has made it challenging to prepare for the pandemic. Our findings showed that lack of preparedness or a response plan, consistent with other studies that confirmed our findings: there are no clear strategies in Yemen, cause a fragile health system, and a complicated political crisis which is considered significant barriers to effective pandemic control [ 2 ]. Saudi Arabia's experience with the MERS epidemic, and its robust public health preparedness and infection control policies as an example of how early investment in health infrastructure can facilitate a more effective response to pandemics [ 24 ]. Compared to Oman, regular press conferences, community awareness campaigns, and a 24/7 MoH call centre were key elements of the pandemic response [ 22 ]. According to the findings of this study, concludes the effectiveness of the response to COVID-19, most of the critical informants informed that there is a lack of coordination between the authorities, insufficient financial budget resources, and inadequate planning have severely impacted Yemen's ability to effectively preparedness to COVID-19. 5. Conclusions In conclusion, this study is the first to assess the scope and magnitude of health and health services in Yemen during the COVID-19 pandemic, with incidence and mortality rates measured from January 2022 to June 2022. It also explains the multi-sectorial actions taken to mitigate COVID-19 in Yemen, identifying a knowledge gap among participants and emphasizing the importance of implementing containment measures. This study reveals both strengths and weaknesses in strategies and approaches within Yemen's fragile health system, particularly in Aden and other governorates. The challenges included an impractical preparedness plan, an uncommitted response, a budget deficit, unachievable policies, and limited access to healthcare facilities. Our recommendations underscore the essential need for establishing an epidemiological center in Aden for future epidemics. To improve epidemic response, it is crucial to develop Yemen's health infrastructure, and health services nationwide, rather than at the level of the governorates, especially after the resolution of the armed conflict.

by prolonged conflict. By employing a mixed-method approach that combines data analysis from international and local sources with in-depth interviews, the study addresses critical gaps in current knowledge regarding the pandemic\u0026apos;s impact on a fragile health system. The research specifically highlights the importance of multi-sectoral efforts in managing public health emergencies and identifies key challenges such as misinformation, inadequate healthcare infrastructure, and the necessity for specialized epidemic hospitals. In the context of existing literature, this study is among the first to provide a comprehensive analysis of Yemen\u0026apos;s health service responses to COVID-19, offering new insights into the specific needs and vulnerabilities of conflict-affected regions during a global pandemic. The findings not only underscore the need for targeted interventions but also contribute to broader discussions on how health systems in fragile states can be strengthened to better withstand public health crises. This work thus advances the field by providing evidence-based recommendations for improving health service delivery in conflict settings, informing both policy and future research initiatives.\u003c/p\u003e"},{"header":"1. Introduction","content":"\u003cp\u003e \u003cdiv class=\"BlockQuote\"\u003e \u003cp\u003eYemen, one of the poorest countries in the Middle East, faces the worst humanitarian crises due to conflict, disease outbreaks, and on top the latest COVID-19 pandemic. More than half the population in Yemen experience poverty and lack access to essential health services [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. Moreover, the country\u0026rsquo;s fragile health system weakened its capacity to effectively detect diseases such as cholera, dengue, and diphtheria, and manage the latest COVID-19 cases [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e, \u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. This is due to conflict which also increases migration, refugees, and internal displacement of people (IDPs) [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe public sector mainly manages Yemen's health system through local health offices that report to the Ministry of Public Health and Population [\u003cspan additionalcitationids=\"CR6\" citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]. However, due to a long conflict, the health system has severely deteriorated, and only half of the health facilities are functional [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e, \u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e, \u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e]. Moreover, the health system is mainly financed through private, out-of-pocket, decreasing the capacity of people to seek health care thus affecting life expectancy and rising child and maternal mortality [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e]. Another major challenge in the health system is the service delivery level due to a shortage of qualified health staff, with only 10 available per 10,000 people [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. As a result, urgent improvements in facilities and human resource training are needed [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eCOVID-19 seriously affected Yemen\u0026rsquo;s health services where a decline in consultations, surgeries, and child vaccinations was significant due to lockdowns and fear of infections [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]. Yemen's already fragile health system has struggled to maintain routine primary care, especially maternal and newborn services, due to the focus on urgent food insecurity issues [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. Humanitarian agencies face challenges in supporting healthcare delivery due to scheduling and data access [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe first case of COVID-19 in Yemen was confirmed in the Hadhramaut governorate on April 10, 2020 [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e, \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e]. By July 20, 2020, there were 1,610 confirmed cases and 446 deaths with a mortality rate of 27%, five times the global average [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e]. By June 1, 2020, Yemen had experienced four waves of COVID-19 with 11,935 reported cases and 2158 deaths [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e] however, underreporting of cases is most likely due to the low capacity of detecting cases [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. In response to the COVID-19 outbreaks in Yemen, the WHO organized early international assistance in collaboration with Yemen\u0026rsquo;s Ministry of Health and 20 partner organizations [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e, \u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e]. However, despite some efforts Yemen did not apply the lockdown needed to mitigate the Spread of COVID-19, mainly due to a lack of good coordination between the government and the people [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]. Additionally, the authorities in Sana\u0026rsquo;a refused to collaborate [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe main aim of this study is to assess the impact of COVID-19 on Yemen's already fragile health system.
