RESUMO

A multitude of demographic, health, and genetic factors are associated with the risk of developing severe COVID-19 following infection by the SARS-CoV-2. There is a need to perform studies across human societies and to investigate the full spectrum of genetic variation of the virus. Using data from 869 COVID-19 patients in Bahrain between March 2020 and March 2021, we analyzed paired viral sequencing and non-genetic host data to understand host and viral determinants of severe COVID-19. We estimated the effects of demographic variables specific to the Bahrain population and found that the impact of health factors are largely consistent with other populations. To extend beyond the common variants of concern in the Spike protein analyzed by previous studies, we used a viral burden approach and detected a protective effect of low-frequency missense viral mutations in the RNA-dependent RNA polymerase (Pol) gene on disease severity. Our results contribute to the survey of severe COVID-19 in diverse populations and highlight the benefits of studying rare viral mutations.

RESUMO

Background: Unintentional injury to children at home is a public health problem and it is a significant cause of death and disabilities. It accounts for 40% of all child deaths. To our knowledge, there have been no similar studies done on Arabic countries that show the prevalence of home injuries among children. Aim: We aimed to assess the adults' knowledge and attitude toward child safety at home in Saudi Arabia. Methods: A cross-sectional study was conducted among 1,301 participants, during August 2017, who are older than 18 years old and have at least one child in the family. Data were collected by an online questionnaire assessing the believes, knowledge, and behavior of the participants. Analysis was carried out using IBM SPSS Software version 21, using descriptive analysis, t-test, and one-way ANOVA. Results: It was found that gender, age, marital status, employment status, and the type of accommodation played key roles in the awareness of children safety at home, the study showed that females and age group above 25, married, employees, and those who lived in flats had more awareness than the other groups, respectively. Conclusion: The majority of the population had good awareness about children's safety at home. Despite the good level of awareness, more public health education is recommended to improve the awareness and the prevention methods of these injuries.
