About this study

BACKGROUND: According to previous reports, all 84 eldery residents in nuersing homes in Yespes (Toledo, Spain), had a 100% of positive serology for COVID-19 in June 2020, but none died nor hospitalized after receiving early treatment with antihistamines. Other case reports have suggested a protective role of amantadine, since infected patients showed a very mild COVID19 infection.

OBJECTIVES.Determine the role of antihistamines and amantadine in the evolution of COVID19.

METHODS. Describe the rate of hospitalization, ICU, survival, postcovid syndrome and thrombosis among COVID 19 cases having antihistamines and amantadine as chronic treatments.

The rates would be stratified by age groups and compared with the same age groups of the population assigned to the public free Access Terrassa Health Consortium.
