Luz ultravioleta lejana para inactivar superficies y aerosoles contaminados con SARS-CoV2.

Abstract

The COVID-19 pandemic, caused by a new type of coronavirus called SARS-CoV2, is an acute infection of the respiratory tract (1, 2) that has spread to more than 200 countries, leaving a fatal toll of more than 4,200 .000 infected and nearly 300,000 deaths, from their appearance in December 2019 to the beginning of May 2020. In Colombia, during that period, more than 13,000 infected and 500 deaths have been counted (3). Due to its rapid spread and high transmission rate, mitigation measures such as quarantine (social distancing), protection barriers (masks, suits, glasses) and physical distancing (keeping 2 m between person and person) have been adopted. Since there is evidence that SARSCoV2 remains active for up to 3 hours in aerosols, 4 hours on copper surfaces, 24 hours on cardboard, 48 hours on stainless steel and 72 hours on plastic (2), one of the challenges in the fight against COVID-19 is to find effective cleaning mechanisms for surfaces, structures and aerosols.
