Abstract
Objective: describe the main information described in the literature about information related to infection by the coronavirus and aspects about the onset of the disease, pathophysiology, immunology and treatment. Literature review: Covid-19, using the SARS-CoV2 virus, despite being from a viral family known even from another pandemic in the past, has mechanisms that need to be studied to understand in detail information about its etiology, mechanisms infection and effective treatments to fight infection. Microscopic analysis of tissue samples in addition to understanding immunology applied to viral defense may be the solution for the development of vaccines that can provide effective protection against the virus and its already known mutations. The treatment and vaccines, for the most part, are still in the testing phase and their distribution to the population after the approval of efficacy, can take a long time, and until then, many people may lose their lives. Final considerations: Studies focused on pathophysiology and especially immunology of SARS-CoV2 can facilitate the development of more effective therapies and vaccines against coronavirus infection, reducing the number of deaths and infections worldwide and helping to reestablish the post-normal economy.
