Background The United Arab Emirates (UAE) was the first country in the Middle East to report severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Serosurveys are essential to understanding the extent of virus transmission. This cross-sectional study aims to assess the seroprevalence of SARS-CoV-2 infection in the Emirate of Abu Dhabi. Methods Between 19 July and 14 August 2020, 4487 households were selected using a random sample stratified by region and citizenship of the head of household (UAE citizen or non-citizen). A cluster sample of 40 labour camps was selected. Data on socio-demographic characteristics, risk factors and symptoms compatible with coronavirus disease 2019 (COVID-19) were collected. Each participant was first tested by Roche Elecsys® Anti-SARS-CoV-2 assay, followed, when reactive, by the LIAISON® SARS-CoV-2 S1/S2 IgG assay. Results Among 8831 individuals from households, seroprevalence was 10·4% [95% confidence intervals (CIs) 9·5–11·4], with higher seroprevalence in Abu Dhabi and Al Ain regions compared with those in Al Dhafra. In households, we found no sex difference and UAE citizens had lower seroprevalence compared with those of other nationalities. Among 4855 workers residing in labour camps, seroprevalence was 68·6% (95% CI 61·7–74·7), with higher seroprevalence among workers from Southeast Asia. In households, individuals with higher body mass indexes demonstrated higher seroprevalences than individuals with normal weight. Anosmia and ageusia were strongly associated with seropositivity. Conclusions The majority of household populations in the Emirate of Abu Dhabi remained unexposed to SARS-CoV-2. In labour camps, SARS-CoV-2 transmission was high. Effective public health measures should be maintained.

Background COVID-19 vaccine hesitancy among healthcare workers (HCWs) is a threat to any healthcare system. Vaccine hesitancy can increase infection risk among HCWs and patients, while also impacting the patients’ decision to accept the vaccine. Our study assessed COVID-19 vaccine acceptance among HCWs in United Arab Emirates (UAE). Methods Using purposive sampling, UAE HCWs registered in the Abu Dhabi Department of Health (DOH) email database were invited to complete an online questionnaire, between November 2020 and February 2021, to understand COVID-19 vaccine acceptance and hesitancy, and trust in sources of information. Simple logistic regression was used to assess the associations between demographic factors with COVID-19 vaccine acceptance. Results Of the 2832 HCWs who participated in the study, 1963 (69.9%) were aged between 25 and 44 years and 1748 (61.7%) were females. Overall, 2525 (89.2%) of the HCW population said they would accept a COVID-19 vaccine. HCWs who were 55+ years of age, male, and physicians/surgeons were more likely to accept a COVID-19 vaccine (OR 3.1, 95% CI 1.5–6.2, p = 0.002; OR 1.8, 95% CI 1.3–2.4, p < 0.001; and OR 1.8, 95% CI 1.1–2.9; p = 0.01, respectively). The most reliable sources for COVID-19 vaccine information were the UAE government (91.6%), healthcare providers (86.8%), health officials (86.3%), and the World Health Organization (WHO; 81.1%). Conclusions COVID-19 vaccine acceptance was high among the UAE HCW population. Several factors were identified as significant determinants of vaccine acceptance. UAE healthcare authorities can utilize these findings to develop public health messaging campaigns for HCWs to best address COVID-19 vaccine concerns — particularly when the government is vaccinating its general population.

BACKGROUND Telemedicine is a care delivery modality that has the potential to broaden the reach and flexibility of health care services. In the United Arab Emirates, telemedicine services are mainly delivered through either integrated hospital outpatient department (OPDs) or community clinics. However, it is unknown if patients’ perceptions of, and satisfaction with, telemedicine services differ between these two types of health care systems during the COVID-19 pandemic. OBJECTIVE We aimed to explore the differences in patients’ perceptions of, and satisfaction with, telemedicine between hospital OPDs and community clinics during the COVID-19 pandemic. We also aimed to identify patient- or visit-related characteristics contributing to patient satisfaction with telemedicine. METHODS In this cross-sectional study that was conducted at Abu Dhabi health care centers, we invited outpatients aged 18 years or over, who completed a telemedicine visit during the COVID-19 pandemic, to participate in our study. Patients’ perceptions of, and satisfaction with, telemedicine regarding the two system types (ie, hospital OPDs and community clinics) were assessed using an online survey that was sent as a link through the SMS system. Regression models were used to describe the association between patient- and visit-related characteristics, as well as the perception of, and satisfaction with, telemedicine services. RESULTS A total of 515 patients participated in this survey. Patients’ satisfaction with telemedicine services was equally high among the settings, with no statistically significant difference between the two setting types (hospital OPDs: 253/343, 73.8%; community clinics: 114/172, 66.3%; <i>P</i>=.19). Video consultation was significantly associated with increased patient satisfaction (odds ratio [OR] 2.57, 95% CI 1.04-6.33; <i>P</i>=.04) and patients’ support of the transition to telemedicine use during and after the pandemic (OR 2.88, 95% CI 1.18-7.07; <i>P</i>=.02). Patients who used video consultations were more likely to report that telemedicine improved access to health care services (OR 3.06, 95% CI 1.71-8.03; <i>P</i>=.02), reduced waiting times and travel costs (OR 4.94, 95% CI 1.15-21.19; <i>P</i>=.03), addressed patients’ needs (OR 2.63, 95% CI 1.13-6.11; <i>P</i>=.03), and eased expression of patients’ medical concerns during the COVID-19 pandemic (OR 2.19, 95% CI 0.89-5.38; <i>P</i>=.09). Surprisingly, middle-aged patients were two times more likely to be satisfied with telemedicine services (OR 2.12, 95% CI 1.09-4.14; <i>P</i>=.03), as compared to any other age group in this study. CONCLUSIONS These findings suggest that patient satisfaction was unaffected by the health system setting in which patients received the teleconsultations, whether they were at hospitals or community clinics. Video consultation was associated with increased patient satisfaction with telemedicine services. Efforts should be focused on strategic planning for enhanced telemedicine services, video consultation in particular, for both emergent circumstances, such as the COVID-19 pandemic, and day-to-day health care delivery.

Appropriate diagnostic testing to identify persons infected with SARS-COV-2 is a vital part of a health system&rsquo;s ability to control the global pandemic of COVID-19 disease. The primary purpose of this review is to provide an overview of the mass testing strategy implemented throughout the UAE and the overall impact it has made on containing and controlling the spread of the disease. This study describes the mass testing strategy and capacity of the UAE during the pandemic of the new coronavirus SARS-COV-2. The UAE has conducted 15 million polymerase chain reaction (PCR) tests to SARS-COV-2, as of 15 November 2020. The number of tests per day varied from 10,000 by the end of March to 120,000 tests per day in November 2020. The mass testing initiative across the entire UAE forms an integral part of a bigger strategy focusing on testing, tracing contacts and isolating positive cases.
