ABSTRACT
Background: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) can be transmitted through direct, indirect, or close contact with infected people by contaminated respiratory droplets or saliva. This study aimed to investigate the epidemiology of coronavirus disease 2019 (COVID-19) and the secondary attack rate (SAR) in the cases' close contact. Methods: A total of 431 confirmed COVID-19 patients were randomly selected using systematic random sampling from 15 May to 13 June 2020. The required data were extracted from the CORONALAB database of the Center for Disease Control and Prevention (CDC) at Shiraz University of Medical Sciences. Detection of COVID-19 was performed using Real-Time Polymerase Chain Reaction (RT-PCR) and nasopharyngeal swabs. SAR was also calculated for different groups. Results: Among the index cases, 64.27% were male, 24.80% were public sector employees, and 4.87% were admitted to the intensive care unit. In addition, most of them aged 30-39 years. The SAR was 11.56% (95% CI: 9.86% to 13.25%) in the close contacts. Accordingly, the highest SAR was observed among the friends, 19.05% (95% CI: 7.17% to 30.92%), followed by the spouses of COVID-19 cases, 16.67% (95% CI: 10.81% to 22.51%). Furthermore, diabetes (6.03%) and cardiovascular disease (5.1%) were the most common comorbidities among the index cases. Conclusion: The findings suggested that the SAR was relatively lower among the close contacts. Considering the familial and non-familial relationships between the index cases and their close contacts were the major causes of disease transmission. Therefore, it is crucial to conduct tracing for COVID-19 contacts in all cases with whom patients have had close contact. © 2023 Authors. All rights reserved.
ABSTRACT
Introduction: The world is currently experiencing a pandemic of COVID-19. The pandemic may affect physical and mental health. Therefore, this study aims to investigate the fear of COVID-19 and study the relationship between fear of COVID-19 and preventive behaviors against COVID-19. Material and methods: We conducted a web-based cross-sectional study to evaluate the fear of COVID-19 and preventive behaviors against COVID-19 among the volunteer population in Golestan Province, Iran in May 2020 and June 2020. The online questionnaire included the Fear of COVID-19 Scale (FCV-19S) and the prevention behaviors against COVID-19, which are used to assess the fear and prevention behaviors of the population, respectively. The data were presented by mean and frequency. Multiple linear regression analysis was performed to identify factors associated with Fear of COVID-19 at a significant level of 0.05 in Stata 14. Results: A total of 734 of the 900 individuals contacted completed the survey, with a participation rate of 81.5%. The mean age of the participants was 33.97 ± 10.68 years and 375 (51.9%) were females. The mean Fear of COVID-19 score in the participants was 19.69 ± 5.96. There was a significant positive correlation between Fear of COVID-19 and preventive behaviors (r = 0.19, p < 0.001). Multiple linear regression analysis showed participants with a higher perceived threat of COVID-19, women, married participants, health workers and people with underlying diseases had higher levels of fear of COVID-19. Conclusions: The fear of COVID-19 in Iranian society is high, which indicates the need to pay attention to the mental health in pandemic conditions. Appropriate intervention action can be designed and implemented according to the factors that affect fear. In addition, it should be noted that people with less fear are less likely to observe the COVID-19’s preventative behaviors.
