Key Words: Ebola virus disease Health care providers Knowledge, attitude and practice Sudan
Background: Ebola virus disease (EVD) is an infectious disease associated with a high fatality rate. Health care providers (HCPs) are frequently infected while treating patients with suspected or confirmed EVD. Knowledge of, attitudes toward, and practices of HCP toward EVD, especially in hot spots, is an essential element to control the disease. Materials and methods: In this descriptive, cross-sectional, health facilityebased study, 258 HCPs were interviewed in different health facilities in hot spots in the targeted states, including district and federal hospitals and health centers, using a self-administrated questionnaire. Results: The majority of respondents were house officers (40.7%), followed by nurses (26.4%). The remaining respondents were registrars, medical officers, and allied health professionals. All participants had heard about EVD. There were significant differences in the knowledge of doctors and allied health care providers regarding modes of transmission and clinical manifestations. Some false information, such as airborne transmission (53.1%) and insect transmission (20.2%), was reported by respondents. The majority of respondents (81.3%) claimed that they would treat patients with suspected EVD while taking a safe approach, 83.5% said they would notify health authorities about cases of suspected EVD, and 91.1% reported not attending any training sessions about EVD. Conclusion: The media plays an important role in increasing awareness about EVD. Regardless, however, researchers recommend more in-service training for HCPs to increase their knowledge about EVD.

Ebola virus disease (EVD) is a serious acute illness that is often fatal if untreated.1 It is caused by infection with a virus of the family Filoviridae, genus Ebola virus.2 The first cases of EVD were reported in 1976 in 2 simultaneous outbreaks, one in Anzara, Sudan (currently the Republic of South Sudan) and the other in Yambuku village, Democratic Republic of Congo. The virus was named after the Ebola River, which runs close to that village.1 Ebola hemorrhagic fever outbreaks constitute a major public health issue in sub-Saharan Africa.3 Multiple outbreaks occurred between 1976 and 2014. In Sudan, cases were reported in 1976 and 2004. A total of 301 people were infected in the 2 outbreaks.4

On August 8, 2014, the World Health Organization (WHO) declared an EVD outbreak in West Africa (Guinea, Liberia, Sierra Leone, and Nigeria) as an extraordinary event and a public health emergency of international importance.5 By January 29, 2015, a total of 22,101 cases and 8818 deaths had been reported.6 By August 25, 2014, more than 240 health care workers had developed the disease, of whom 120 had died.7 In Sierra Leone, the confirmed EVD incidence was 103-fold higher among health care providers (HCPs) than in the general population.8 During epidemics, the virus is transmitted through direct human-to-human contact. HCPs are frequently infected while treating patients with suspected or confirmed EVD. This occurs through close contact with patients when infection control precautions are not strictly followed.1 HCPs’ detailed knowledge of EVD is an essential preventive tool, given that multiple infectious diseases that are endemic in sub-Saharan Africa, like malaria and typhoid fevers, mimic the

initial symptoms of EVD. In addition, neither doctors nor the public are familiar with the disease. Moreover, patients infected with these diseases will often need emergency care, and treating personnel may see no reason to suspect EVD and thus might not take recommended safety precautions. Meanwhile, adherence to such precautions has been associated with a dramatic drop in cases among medical staff.7 This finding highlights the importance of assessing HCPs’ knowledge, attitude, and practice related to controlling EVD. As a result of conflicts in South Sudan, the site of a previous EVD outbreak, more than 635,000 refugees flooded into neighboring countries, including Sudan.9 This situation underscores the importance of instituting and maintaining preventive measures against EVD. The Sudan Ministry of Health has declared that the country is free of the disease. On top of that, a strategy for preventing EVD outbreaks was established, including instituting a notification system, increasing general awareness of EVD, and training HCPs in how to handle suspected cases.10

MATERIALS AND METHODS Study area This study was conducted in hospitals and health centers in hot spots located in Khartoum and White Nile States. Khartoum State is divided into 6 localities. We selected 3 hot spots in the outskirts of Khartoum: Jabl Awlia, Sharg Alnil, and Umbada. Collectively, these 3 localities contain approximately 3.5 million residents who came from different parts of Sudan because of conflicts and drought.11 In White Nile State, we selected Kosti, the largest city in the state, which represents the crossroads of the north, east, and south of Sudan and is the main portal of connection between Sudan and South Sudan,12 where the first cases were reported. Health facilities in Sudan are divided into 3 levels: primary (health centers), secondary (district hospitals), and tertiary (federal hospitals). We selected 3 health centers and 1 district hospital from each of aforementioned localities in Khartoum State. In addition, we chose a federal hospital at random. In White Nile State, we also chose3 health centers and 1 district hospital in Kosti, but no federal hospital, because these are no such hospitals in the state.

RESULTS
This cross-sectional study was conducted among HCPs, including consultants, senior specialists, specialists, registrars, medical officers, house officers, nurses, and other allied health professionals, working in the selected health facilities using convenient sampling. The single federal hospital selected for the study, Central Police Hospital, is the referral hospital for cases of suspected EVD detected at border crossing points. Each locality had a district hospital selected. Health centers were elected using simple random sampling. The study was conducted in November and December 2014. Data were collected using a pretested, self-administrated questionnaire written in Arabic comprising 44 questions divided into 6 sections. The first section solicited demographic data, the second section evaluated knowledge of the nature of the organism, and the third and fourth sections assessed knowledge regarding modes of transmission and symptoms of EVD. The fifth section concentrated on safety precautions, and the last section included questions about the respondent’s attitude toward patients with suspected EVD and on efforts of health authorities against EVD. The respondents were given sufficient time to read, comprehend, and answer all questions. They were informed that their
Of the 258 respondents (response rate, 78.3%), the majority were house officers (40.7%), followed by nurses (26.4%). The remaining respondents were registrars, medical officers, and allied health professionals (medical assistants, midwives, and laboratory technicians). The majority of the respondents were females (71.7%), and 69.8% of the respondents were under age 30 years. Characteristics of the study participants are summarized in Table 1. In multiple response questions, 68.6% of HCPs reported hearing about EVD from classical media (ie, television, radio, and newspapers), whereas 25.2% did so from new media (social networks), and 23.3% from medical websites. Only 19% gained information from medical books, and 8.5% learned about EVD from other sources, such as training sessions and other persons. The respondents’ knowledge of EVD was assessed in terms of nature of the disease, incubation period, diagnostic tests, and outcomes. The data are presented in Table 2. In terms of HCPs’ knowledge of modes of transmission, clinical manifestations, and prevention, the responses were rated as poor (<50%), average (50%-60%), good (60%-80%), or very good (>80%) for each of the aforementioned domains depending on the number of correct answers. Significant differences in knowledge of modes of

transmission and clinical manifestations were found between doctors (house officers, registrars and medical officers) and allied health care providers (nurses, laboratory technicians, and others Table 3). False information reported by respondents included airborne transmission (53.1%) and insect transmission (20.2%). In addition, 16.7% reported believing that a licensed vaccine is available (at time of data collection), and 8.5% believing that there is a specific EVD treatment. The majority of respondents (83.5%) claimed that when encountering a patient with suspected EVD, they would break patient confidentiality by informing contact personnel to take safety precautions, and inform health authorities after exclusion of other common differential diagnoses. In addition, the majority (81.3%) claimed that they would treat patients with suspected EVD taking a safe approach, 93.5% would isolate these patients from others in a special ward, and 78% would allow relatives visits. Table 4 presents details about respondents’ approach to dealing with the body of a deceased EVD patient, including to whom it should be delivered and where to prepare it in the widely practiced Islamic manner in Sudan, which involves close contact with all parts of the body. In terms of the susceptibility of Sudan to an EVD outbreak, 87.6% of respondents considered Sudan at risk, among whom 56.6% ranked it as a high-risk country. Despite this, 91.1% never attended any training sessions on EVD. Many respondents characterized health authorities’ efforts against EVD as absent (41.7%) or weak (38.1%) (Fig 1).
DISCUSSION A previous Knowledge, Attitude and Practice (KAP) study regarding EVD done among HCPs in a tertiary care referral hospital in central Karnataka, India, found that 41.2% got their knowledge about EVD from electronic media and 44.5% did so from classical media, including television, radio, and newspapers.13 In comparison, in the present study, 68.6% of respondents learned about EVD from classical media. In a recent cross-sectional KAP study on EVD conducted by the World Health Organization among 1413 individuals from multiple households in 9 districts in Sierra Leone, only 39% of respondent knew that it is a viral illness.14 In contrast, in the present study, 93.8% knew the correct answer. The Indian study used a similar grading system as ours to evaluate knowledge of EVD, and found that the majority of doctors

achieved good (38.4%) or average (30.7%) grades.13 In contrast, in the present study, doctors predominately achieved poor (27.85%) or very good (27.7%) grades. Among allied health personnel, 41.5% achieved poor grades concerning knowledge about modes of transmission, clinical manifestations, and means of prevention. We found significant differences in knowledge of modes of Ebola virus transmission and clinical features between doctors and allied health personnel. One possible explanation for this difference is that doctors are more educated in microbiology and infectious diseases because of their continuous professional development. Misconceptions regarding modes of EVD transmission were evident among respondents in the KAP study of households in Sierra Leone, with 29.7% believing that EVD is transmitted by the airborne route and 30.4% believing that transmission can occur through mosquito bites.14 In our study, nearly 50% of respondents cited airborne transmission, and approximately 20% identified insects as a mode of EVD transmission. This misinformation can be attributed to lack of training about EVD in the majority (91.1%) of respondents. Consequently, 79.8% of respondents characterized efforts by local health authorities against EVD as weak or absent. This study has several limitations. Self-reported responses might not always reflect the individual’ actual practice. In addition, it was difficult to collect data from consultants, most of whom were either busy or unavailable.

CONCLUSION Classical media and the new emerging social media play important roles in increasing awareness of EVD. Nonetheless, the present study demonstrates a lack of knowledge among HCPs, especially among allied health personnel. In addition, it is evident that the vast majority of HCPs do not receive specific training regarding EVD. Thus, we recommend more in-service training for HCPs to provide updated scientific knowledge regarding EVD and caring for patients with EVD. References 1. World Health Organization.
