The new SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2) belongs to the family of coronaviruses, and it is a new strain of coronavirus that has not been previously identified in humans. It causes a contagious disease, which affects the respiratory system and can lead to severe complications in some cases. This virus was detected in China, then rapidly spread to almost all countries. Because of their complexity and the malignancy of the symptoms, they remain a center of interest for researchers. Herein, we provide a review in terms of transmission, clinical presentation, diagnosis, and treatment options in clinical trials of COVID-19 (coronavirus disease 2019), because readers need to update themselves regularly, and there is still much more to know about it.

Glioblastoma is the most aggressive malignant type of central nervous system tumors. The literature review revealed that the most common genetic abnormalities in primary and secondary glioblastomas are IDH1 / 2 mutations, p53 mutations, and overexpression of EGFR.To our knowledge, this is the first Moroccan study to provide a global picture of genetic studies performed on Moroccan patients to describe genetic markers and their frequency in our population.An in-depth research in ScienceDirect and Pubmed on glioblastoma articles treated in Morocco, this research is based on the following keywords: glioblastoma in Morocco, primary glioblastoma in Morocco, secondary glioblastoma in Morocco.We found only three research articles on genomic alteration of IDH1 / 2, p53 and EGFR expression. The frequency of these gene mutations in our population was similar to those reported from other populations.Additional molecular studies need to be performed on other genes to describe other genetic markers in the Moroccan population.
