Étude épidémiologique de coronavirus dans la wilaya de Mila

Abstract

COVID-19 is an infectious disease recently emerged in Wuhan City, Hubei Province, China. This infection was then linked to SARS-CoV-2 virus which is a non-segmented positive sense RNA virus. Typically, fever, cough and tiredness are some of the most frequent symptoms. Infected patients may also exhibit severed shortness of breath, low blood oxygen, lung damage as the infection progress. Our retrospective epidemiological study, conducted in Mila district, was based on clinical data analysis from 957 hospitalized patients that were admitted to both ‘Meghloui brother’s’ and ‘Tobal brothers’ hospitals. Our findings showed that there was a correlation between number of coronavirus-infected individuals and the population density. Men are more susceptible to COVID-19 infection than women and this seems due to the high expression level of ACE2 SARS-CoV-2 receptor. Furthermore, COVID-19 severity was generally associated with coexisting chronic diseases. Our results showed that Omicron variant infected frequently younger individuals then older ones due to development of patients immune system during the three first waves.
