Brief Summary

Since the beginning of 2020, SARS-CoV-2 outbreak spread over the world, conducting in a pandemic state declared by the world health organization in March 2020. Conflicting data have been yet published regarding to the incidence rate of COVID-19 infection in altitude. Mainly based on analysis from national Peru database, some authors argued that COVID-19 disease, as well as case fatality rate was less frequent in altitude. However, epidemiological data are lacking regarding to the prevalence of COVID-19 in altitude, and more specially in high altitude. Aim of this cross-sectional study is to assess the prevalence of seroconversion for the SARS-CoV-2 in the population of La Rinconada, a mining town at 5,100 m, the highest city in the world.
