Epidemiology and Clinical Characteristics of the First 500 Positive Cases of COVID-19. A Multicenter Retrospective Study across the Najran Region of the Kingdom of Saudi Arabia (KSA)

Introduction: Coronavirus Disease 2019 (COVID-19) is a viral infection that was first reported in Wuhan, China on 31 December 2019. This study aimed to clarify the epidemiology and clinical characteristics of 500 first COVID-19 in the Najran region, Saudi Arabia. Material and Methods: A multi-center retrospective study design was employed to study the first 500 confirmed COVID-19 positive cases in Najran province, Kingdom of Saudi Arabia (KSA). Data were collected from 1 March 2020 until 1 July 2020 and provided by the Infection Prevention and Control (IPC) department from the hospitals. Included cases were confirmed using real-time reverse transcriptase-polymerase chain reaction (RT-PCR). Demographic, vital signs, symptoms, incubation period, travel or exposure history medical history, and comorbidities were collected. Logistic regression analysis was used to explore the association between potential risk factors associated with symptoms occurrence of COVID-19. Results: The median age of 500 COVID-19 patients was 31 years;333 (66.6%) males. A total of 34 (6.8%) were Healthcare Workers (HCWs). Out of the 500 patients, 180 (36%) had at least one comorbid disease. The most common symptoms on admission were fever 281 (56.2%), cough 266 (53.2%), shortness of breath 166 (33.2%), and malaise 113 (22.6%). Most of the patients presented with mild disease severity 310 (62%). Nationality, age, and Diabetes Miletus (DM) were independently and significantly associated with being symptomatic (P < 0.05). Compared to Saudi nationals, other nationality patients were most likely to have symptoms (β = 2.968, CI = 2.002 - 4.400, P = 0.0010). For every 1 year increase in age, the risk of being symptomatic increased by 5.8% (β = 1.045, CI = 1.033 - 1.058, P = 0.001). Compared with non-DM patients, DM patients had a 4.05 times higher risk (β = 4.05, CI = 2.188 - 7.507, P = 0.001) of getting symptoms. Conclusions: The study concluded that the majority of the COVID-19 patients were symptomatic or had mild disease severity. Age, nationality, and DM were the important risk factors in being symptomatic.

An Assessment of Healthcare Workers Knowledge about COVID-19

Introduction: Coronavirus disease 2019 (COVID-19) is caused by a viral infection and considered the third coronavirus emerging among human beings over the past two decades. Healthcare Workers (HCWs) are at high risk of acquiring this serious infection during providing care to patients. Therefore, it’s crucial to assess the knowledge of the HCWs about COVID-19. Methods: A multicenter cross-sectional study was conducted on HCWs working at public hospitals and Primary Healthcare (PHC) centers in the Najran region, KSA to evaluate the staff’s knowledge toward COVID-19. The questionnaire consisted of two parts, the first part included the demographic data, and the second part involved questions related to the COVID-19. Results: 451 HCWs participated in this study and the median of overall knowledge score was 67%. Most HCWs properly identified symptoms (82.9%), mode of transmission (78.5%), the incubation period (96.4%), the way of preventing the infection (91.5%), the COVID-19 is not same as MERS-CoV (74.3%) and availability of a vaccine against the COVID-19 (82%). However, HCWs were less likely to identify the source of COVID-19 when it was discovered in China (22.5%), the mortality rate (44.6%), and the presence of treatment (32.1%). Overall knowledge score was statistically significantly associated with profession (P = 0.034), educational level (P = 0.033), and availability of the infection control in the workplace (P = 0.006). Conclusion: The findings of this study demonstrated an intermediate level of knowledge of HCWs about COVID-19. Intervention programs are urgently needed to raise the knowledge of HCWs about this global public health issue.
