IntroductionIn the United States, injuries are the leading cause of death during the first four decades of life,' and are responsible for half of all visits to hospital emergency departments.2
This study measured the incidence of cause-specific trauma in the Cleveland and Lorain-Elyria Standard Metropolitan Statistical Areas (SMSAs), population 2.2 million, as reported to hospital emergency departments (ED). Cases were selected according to a stratified probability sampling plan (N = 9268). The participating hospitals accounted for 97.6 per cent of 903,346 ED
In the first six months of its deadly spread across the world, the Covid-19 incidence has exhibited interesting dichotomy between the rich and the poor countries. Surprisingly, the incidence and the Case Fatality Rate has been much higher in the richer countries compared with the poorer countries. However, the reasons behind this dichotomy have not been explained based on data or evidence, although some of the factors for the susceptibility of populations to SARS-CoV-2 infections have been proposed. We have taken into consideration all publicly available data and mined for the possible explanations in order to understand the reasons for this phenomenon. The data included many parameters including demography of nations, prevalence of communicable and non-communicable diseases, sanitation parameters etc. Results of our analyses suggest that demography, improved sanitation and hygiene, and higher incidence of autoimmune disorders as the most plausible factors to explain higher death rates in the richer countries Thus, the much debated hygiene hypothesis appears to lend credence to the Case Fatality Rate dichotomy between the rich and the poor countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
