COVID 19 has placed stress on all national health systems worldwide. Recent studies of the disease have evaluated different variables; Quarantine models, mitigation efforts, damage to the mental health, mortality of the population with chronic diseases, diagnosis of the disease, use of masks and social distancing, or mortality regarding different age groups. This study focuses on the capacity of each National Health System to respond to the disease. The WHO recognizes four national health systems: (1) The Beveridge model, (2) the Bismarck model, (3) the national health insurance model, and (4) the “out of pocket” model. The capacity to respond to the pandemic is analyzed through the days where the morality doubles by comparing the medians of the doubling mortality variables using the Mood's median test method. The results obtained show similar medians between the study groups; The COIVID 19 pandemic saturates health systems regardless of their management structures and the result measured with the variable ‘days with double the mortality’ is similar among the 4 national health systems.
