Middle East respiratory syndrome coronavirus and human-camel relationships in Qatar
This article investigates camel raising as a possible cause of transmission of the Middle East Respiratory Syndrome coronavirus (MERS-CoV) on the Arabian Peninsula. Drawing on collective research among camel workers in Qatar, it shows the difficulties of asking questions about camel raising in the context of a potential zoonosis, given the secretive nature of herding practices and the values attached to camels in Arab societies. It suggests that the concentration of camels in farms and central markets after the ban of camel grazing as well as the revival of the tradition of drinking camel milk have increased the risks of the transmission of MERS-CoV from camels to humans. The recent valorisation of camels, in the context of the transformation of Qatar from a pastoral economy to a global trade centre, may appear to be an obstacle in the surveillance of MERS-CoV, since camel owners are prone to denying that their animals are infected, but it can be converted into an asset if public health becomes a key element of national pride alongside camel raising
Improving influenza vaccination rate among primary healthcareworkers in Qatar
The purpose of this study was to improve influenza vaccination, and determine factors influencing vaccine declination among health care workers (HCW) in Qatar. We launched an influenza vaccination campaign to vaccinate around 4700 HCW in 22 Primary Health Care Corporation (PHCC) centers in Qatar between 1st and 15th of November, 2015. Our target was to vaccinate 60% of all HCW. Vaccine was offered free of charge at all centers, and information about the campaign and the importance of influenza vaccination was provided to employees through direct communication, emails, and social media networks. Staff were reported as vaccinated or non-vaccinated using a declination form that included their occupation, place of work and reasons for declining the vaccine. Survey responses were summarized as proportional outcomes. We exceeded our goal, and vaccinated 77% of the target population. Only 9% declined to take the vaccine, and the remaining 14% were either on leave or had already been vaccinated. Vaccine uptake was highest among aides (98.1%), followed by technicians (95.2%), and was lowest amongst pharmacists (73.2%), preceded by physicians (84%). Of those that declined the vaccine, 34% provided no reason, 18% declined it due to behavioral issues, and 21% declined it due to medical reasons. Uptake of influenza vaccine significantly increased during the 2015 immunization campaign. This is attributed to good planning, preparation, a high level of communication, and providing awareness and training to HCW with proper supervision and monitoring. 1 2017 by the authors.

Prevalence and trends of transfusion transmissible infections among blood donors in the State of Qatar, 2013-2017.
Millions of lives around the world are being saved annually through blood transfusion. However, blood transfusion is among the essential vehicles for transmitting infections. The overall prevalence of Transfusion Transmissible Infections among blood donors differs around the world, reflecting the variation in the prevalence of these infections. This study aims to assess the prevalence and trends of Transfusion Transmissible Infections among blood donors in Qatar. This is a cross-sectional study utilizing donation records of 5 years from January 2013 to December 2017. We included in the study results for all screening and confirmatory tests for Hepatitis B Virus, Hepatitis C Virus, Human T-lymphotropic Virus-I/II, Syphilis and Malaria. Among the 190,509 donations received at the donation centre during the study period, about 91% of donations were received from males and 9% from females. The overall positivity rate for all tests was 1.87, 2.23, 1.78, 2.31, 2.67% for the years 2013 through 2017, with an increasing yearly trend by 6% each year. The overall positivity rates for Hepatitis C Virus, Human T-lymphotropic Virus-I/II, Hepatitis B Virus, Syphilis and Malaria (2013-2017) were 0.60, 0.18, 0.30, 0.43 and 0.20%, respectively. The overall positivity rate of all tests combined for the Transfusion Transmissible Infections demonstrated a gradually increasing trend from 2013 to 2017. However, the trend for each infection (Hepatitis C Virus, Hepatitis B Virus, Syphilis and Malaria) was fluctuating except for Human T-lymphotropic Virus-I/II, which was increasing. Supporting the development of effective prevention and control strategies requires further comprehensive investigations for better estimation of the burden of these infections.The authors gratefully acknowledge the Blood Donation Center at HMC for their support
Malaria Chemoprophylaxis for Travelers: The Knowledge of Physicians in the State of Qatar, 2017
Introduction: Malaria is among the most significant travel-related infections encountered by travelers to endemic countries in terms of morbidity and mortality. In Qatar, imported malaria has increased over the last 5 years; 493 travel-related cases were confirmed in 2016. In the current study, the knowledge of malaria chemoprophylaxis among physicians in the State of Qatar was assessed. Methods: This was a cross-sectional study conducted during a national travel health workshop at the Ministry of Public Health, Qatar. Physicians participating in the workshop from different national healthcare institutions providing travel medicine services were invited to voluntarily complete a self-administered, structured questionnaire. Results: Forty-two medical doctors participated in the study (92 response rate). Based on their specialty, almost two-thirds (64.3%) of the participants were family medicine physicians, and one-fifth (21.43%) were general practitioners. Furthermore, most of the doctors were untrained in travel medicine. The majority of participants demonstrated a good knowledge of the malaria parasite (100%), Plasmodium species (64.3%), incidence (83.3%), transmission (66.7%), and drug-resistance (95.2%) of malaria. Additionally, most physicians (>90) were knowledgeable about the major features of severe or complicated malaria as well as malaria prevention and chemoprophylaxis. Conclusion: This study highlights several areas of good knowledge on travel-related malaria prophylaxis and prevention among the study participants; however, there are still a few knowledge gaps that require mitigation. Continuing training programs on malaria prevention in travelers will sustain this good level of knowledge among physicians and improve the quality of pre-travel advice provided by travel medicine practitioners in Qatar
Epidemiology of respiratory infections among adults in Qatar (2012-2017).
Limited data is available about the etiology of influenza like illnesses (ILIs) in Qatar. This study aimed at providing preliminary estimates of influenza and other respiratory infections circulating among adults in Qatar. We retrospectively collected data of about 44,000 patients who visited Hamad General Hospital clinics, sentinel sites, and all primary healthcare centers in Qatar between 2012 and 2017. All samples were tested for influenza viruses, whereas about 38,000 samples were tested for influenza and a panel of respiratory viruses using Fast Track Diagnostics (FTD) RT-PCR kit. Among all ILIs cases, 20,278 (46.5%) tested positive for at least one respiratory pathogen. Influenza virus was predominating (22.6%), followed by human rhinoviruses (HRVs) (9.5%), and human coronaviruses (HCoVs) (5%). A detection rate of 2-3% was recorded for mycoplasma pneumonia, adenoviruses, human parainfluenza viruses (HPIVs), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ILIs cases were reported throughout the year, however, influenza, RSV, and HMPV exhibited strong seasonal peaks in the winter, while HRVs circulated more during fall and spring. Elderly (>50 years) had the lowest rates of influenza A (13.9%) and B (4.2%), while presenting the highest rates of RSV (3.4%) and HMPV (3.3%). While males had higher rates of HRVs (11.9%), enteroviruses (1.1%) and MERS CoV (0.2%), females had higher proportions of influenza (26.3%), HPIVs (3.2%) and RSV (3.6%) infections. This report provides a comprehensive insight about the epidemiology of ILIs among adults in the Qatar, as a representative of Gulf States. These results would help in improvement and optimization of diagnostic procedures, as well as control and prevention of the respiratory infections.This study was supported by funds from Hamad Medical Corporation (grant # 16335/16) and Qatar University (grant # QUCG-BRC-2018/2019-1)
Barriers to Practicing COVID-19 Preventive Behaviors Among Migrant Workers in Qatar: A Qualitative Study During the First Wave of the Pandemic
Objectives: Manual and Craft Workers (MACWs), who constitute more than 80% of the population, were identified to be a vulnerable group to COVID-19 in Qatar. The goal of this study is to identify the limitations face MACWs in Qatar towards practicing the COVID-19 preventive measures and thereby designing behavioral change strategies.
Methods: This is a qualitative research study in which individual interviews and focus group discussions were utilized for a deep understanding of the phenomenon from key informants. Four onlive individual interviews and four focus groups (n = 55) were conducted and transcribed verbatim. Inductive qualitative analysis was followed to discover the themes of the interviews. Data were analyzed using constant comparative techniques.
Results: Major themes elicited from the analysis revealed that the barriers to following COVID-19 preventive behaviors among migrant workers in Qatar included barriers related to knowledge and risk perception; lifestyle and habits; nature of work and living conditions, and barriers related to health communication, diversified cultures, and languages.
Conclusion: The findings would support constructing culturally sensitive health education messages and planning for effective health communication campaigns
EPIDEMIOLOGY OF MALARIA IN THE STATE OF QATAR, 2008-2015
Background and Objectives
Imported malaria poses a serious public health problem in Qatar because its population is “naïve” to such infection; where local transmission might lead to serious life-threatening infection and might even trigger epidemics.
Methods
This study is a retrospective review of the imported malaria cases in Qatar reported by the malaria surveillance program at the Ministry of Public Health (MoPH), during the period between January 2008 and December 2015. All cases were imported and underwent parasitological confirmation through microscopy.
Results
A total of 4092 malaria cases were reported during 2008-2015 in Qatar. The demographic features of the imported cases show that the majority of cases were males (93%), non-Qatari(99.6%), and aged 15 to 44 years(82.1%). Moreover, P. vivax was found to be the main etiologic agent accounting for more than three-quarters (78.7%) of the imported cases. In addition, almost a third (33.1%) of the cases were reported during the months of July, August, and September.
Conclusions
Imported malaria in Qatar has witnessed an increase during the past 7 years, despite a long period of constant reduction; where the people most affected were adult male migrants from endemic countries. Many challenges need to be overcome to prevent the reintroduction of malaria into the country
Demographics and Epidemiology of Hepatitis B in the State of Qatar: A Five-Year Surveillance-Based Incidence Study
Background: Expatriates represent >80% of Qatar’s population, mostly arriving from countries in Africa and Asia that are endemic with many diseases. This increases the risk for introducing new pathogens into the country and provides a platform for maintenance of endemic pathogen circulation. Here, we report on the incidence and epidemiological characteristics of hepatitis B in Qatar between 2010 and 2014. Methods: We performed a retrospective epidemiological data analysis using the data available at the surveillance system of the Ministry of Public Health (MOPH) in Qatar. Data were collected from distinctive public and private incorporates around the nation. Reported cases of hepatitis B patients represent those who met the stringent case definition as per World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) guidelines and eventually reported to MOPH. Results: The annual incidence rates of hepatitis B cases were 30.0, 34.2, 30.5, 39.4, and 19.8 per 100,000 population in 2010, 2011, 2012, 2013, and 2014, respectively. There was no specific trend or seasonality for the reported cases. The incidence rates were higher in females compared to males between 2010 and 2012, but similar in 2013 and 2014. The highest incidence rates were reported among individuals between 25 and 34 years of age. No cases were reported in children younger than five years in 2013 and 2014. Rates of hepatitis B cases declined dramatically in 2014, in both Qataris and non-Qataris, as compared to the previous years. Conclusion: Our results indicate a dramatic decline of hepatitis B cases in Qatar but mandate improved surveillance and vaccination efforts in expatriates in the nation. View Full-TextMOP
Pre-symptomatic and asymptomatic transmission of COVID-19: Implications for control measures in Qatar
Public health control measures for communicable diseases are often based on the identification of symptomatic cases. However, emerging epidemiological evidence demonstrates the role of presymptomatic and asymptomatic transmissions of coronavirus disease 2019 (COVID-19). Understanding high-risk settings where transmissions can occur from infected individuals without symptoms has become critical for improving the response to the pandemic. In this review, we discussed the evidence on the transmission of severe acute respiratory syndrome coronavirus-2, its effect on control strategies, and lessons that can be applied in Qatar. Although Qatar has a small population, it has a distinct setting for COVID-19 control. It has a largely young population and is mostly composed of expatriates particularly from the Middle East and Asia that reside in Qatar for work. Further key considerations for Qatar and travel include population movement during extended religious holiday periods, screening and tracing of visitors and residents at entry points into the country, and expatriates living and working in high-density settings. We also consider how its international airport serves as a major transit destination for the region, as Qatar is expected to experience a rapid expansion of visitors while preparing to host the FIFA World Cup in 2022
