Background: In 2020, shortly after recognizing the COVID-19 virus in China on March 11, the World Health Organization (WHO) declared the Covid-19 outbreak a pandemic. It is estimated that COVID-19 is responsible for millions of morbidities and deaths globally, causing devastating health, social and economic crises. This ecologic study aimed to define the correlation between a few key elements of a national health system (i.e., quality of health care services, rate of provided COVID-19 diagnostic tests, and coverage of flu vaccine in the preceding years of the COVID-19 pandemic) and the fatality rate of COVID-19 in countries that were affected by the Covid-19 epidemic in the early phase of the pandemic.Methods: In this ecological study, data regarding the total population, number of active cases, total cases, mortality, and time to peak of the COVID-19 epidemic for the countries with defined criteria and the required data available were collected from the Worldmeter database. Thehealth system quality of the selected countries was obtained using a report by WHO (Measuring Overall Health System Performance for 191 Countries). The Flu vaccine coverage of the selected populations was ordered and ranked using graphs provided by a joint VENICE–ECDC–WHO survey. The analysis was done by fitting meta-regression using rates and confidence intervals. A forest graph was used to show the summary of the results. R version 6.3 (package meta) was used to do the analysis.Results: The average Case fatality rate (CFR) of the 26 selected countries was 115 per 1000 for COVID-19. Testing for heterogeneity suggested that CFR was highly heterogeneous among the countries. The regression analysis results suggested that CFR for COVID-19 was inversely related to the rate of COVID-19 diagnostic tests and was directly related to the rate of flu vaccine coverage).Conclusion: The direct correlation between flu vaccine coverage and CFR of COVID-19 may suggest a positive effect of the natural circulation of flu infection on the effectiveness of the individuals’ immune response. Also, the natural flu infection may protect those who could not tolerate the respiratory complications of COVID-19 infection. The results may help NHSs to cope better with future pandemics. In addition, to provide a faster and more effective response to any future infectious pandemic, better access to diagnosis tests seems to be an effective approach in reducing morbidity and mortality.

Background: Traffic accidents are considered a major public health problem in many parts of the world. This study aimed to investigate the epidemiology of the accidents leading to pedestrians’ death in Ahvaz, Iran, in 2015-2017.Methods: This descriptive cross-sectional study was conducted in 2015-2017. The statistical population was pedestrians who died in traffic accidents in Ahvaz city. The data collection source was the Forensic Medicine Organization. The data were analyzed using the SPSS 16 software using descriptive statistics and chisquare test. Results: Among the 165 pedestrians who died in traffic accidents, 72.1% (119 people) were male and 27.9% (46) female. The mean age of the deceased subjects was 38.38±2.44. The highest frequencies of death in the age groups over 65, under 7, and 25-34 years old were 19.4% (32 people), 14.5% (24 people), and 14.5% (24 people), respectively. Most of the deceased were illiterate (34.5% (57 people)), self-employed (24.2% (40 people)). The final cause of death in more than half of the pedestrians was head trauma (64.8%) (107 people), and most of the deceased had died in hospitals (71.5%) (118 people).Conclusion: Considering that young and older people are two high-risk groups in car accidents, training safety and improving pedestrian safety by creating a safer environment can play a significant role in reducing deaths.

Introduction: Traffic accidents are considered a major public health problem in many parts of the world. The present study aimed to investigate the epidemiology of fatal traffic accidents in Yasouj city during the years 2014-2015. Methods: This descriptive-analytical study was carried out through a cross-sectional method and the study population included all individuals who had died in traffic accidents in Yasouj city during 2014-2015. The source of data collection was the Legal Medicine Organization. The data were analyzed through SPSS 16,using descriptive statistics and Chi-square test. Results: The mean age of the deceased was 35.44 ± 20.99 years. The highest death rate was observed in the age groups over 25-34 years old (21.3%), 15-24 years (17.6%) and 35-44 years (17%), respectively. Most of the deceased were male (75%), single (55.4%), illiterate (44%), self-employed (29.3%) and residents of rural areas (52.3%). The ultimate cause of death of more than half of the deceased was head trauma (30.7%) and most of the deceased had died at the accident site (55.4%). 52.7% had died of collision with a passenger car. There was a significant association between the location of death and location of accident (outside/inside)(p-value=0.004); also, the result showed no significant relationship between the cause of death and location of accident (p-value <0.001) and type of vehicle (p-value <0.001).

Introduction: Deaths from traffic accidents (RTIs) are a major public health problem in all societies, especially in the low and middle-income countries; the present study was conducted to investigate the epidemiology of fatal road traffic accidents in Ahvaz city. Methods: This is a cross-sectional study which included all deaths from RTIs in Ahvaz province (Southwest Iran) admitted to forensic medicine during 2015-2016. ICD-10 was used as diagnostic criteria. Demographic variables as well as injury circumstance) name, surname, phone number, age, sex, season, month, day, accident location, vehicle type, status of the injured person (were recorded by trained research team in forensic medicine. Descriptive data are reported. SPSS 20 software was used for analysis of data. Results: During years 2015-2016, a total of 50 deaths occurred due to road accidents in Ahvaz province. The mean age was 34.99 ± 19.98 years. The mortality rate was higher in men (79.4%), married subjects (57.4%), illiterate ones (26.2%), self-employed subjects (34.6%) and residents of urban areas (78.8%). There were statistically significant relationships between the accident location and the place of death, and between the trauma spot and the cause of death (P <0.001). Conclusion: The results of this study showed that most of the deceased were male, married and young, so preventive measures such as precise traffic surveillance and enforcement of the regulations for safe driving are considered essential.
