MEXICAN HUMAN LEUKOCYTE ANTIGEN ALLELES MIGHT PREDICT CLINICAL OUTCOME IN SARS-COV-2 INFECTED PATIENTS.

Country border lines are illusory and do not restrain the spread of pathogens. For instance, the US has now become the epicenter of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, but just South of its border, in Mexico, confirmed cases have only surpassed a thousand patients, and fatalities are less than a hundred. Such drastic differences replicate worldwide, with no merit due to health-care policies, but probably to ancestry and genetics.
