Abstract
If the current rate of infection are to be better managed, and future waves of infection kept at bay, it is absolutely necessary that the conditions and mechanisms of exposure to Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) be better understood, as well as the downstream severe or lethal clinical complications. While the identification of notable comorbidities has now helped to define broad risk groups, the idiosyncratic responses of individual patients can generate unexpected clinical deterioration that is difficult to predict from initial clinical features. Thus, physicians caring for patients with COVID-19 face clinical dilemmas on a daily basis. The ability to decipher individual predispositions to SARS-CoV-2 infection or severe illness, in light of variations in host immunological and inflammatory responses, in particular as a result of genetic variations, would be of great benefit in infection management. To this end, this work associates the description of COVID-19 clinical complications, comorbidities, sequelae, and environmental and genetic factors. We also give examples of underlying genomic susceptibility to COVID-19, especially with regard to the newly reported link between the disease and the unbalanced formation of neutrophil extracellular traps. As a consequence, we propose that the host/genetic factors associated with COVID-19 call for precision medicine in its treatment. This is to our knowledge the first article describing elements towards precision medicine for patients with COVID-19.
