CoEHAR researchers investigated for the first time the relationship between biochemically-verified smoking status and SARS-CoV-2 infection in a large population study. The study “The impact of laboratory-verified smoking on SARS-CoV-2 infection: Results from the Troina sero-epidemiological survey”, found that the prevalence of SARS-CoV-2 antibody positivity were reduced in smokers compared to former and never smokers (19.8% vs. 31%)
Duke University and CoEHAR- together with Istituto Oasi Maria SS di Troina and the City Council- concluded the first part of the study to assess the prevalence of coronavirus infections in the city of Troina, a previous red zone due to the high rate of infections by COVID-19
In the past few days, seroepidemiological tests on citizens have been performed to assess the impact of smoking on the Covid-19 infections on the most vulnerable part of the population. The subjects of the study were selected according to a multi-layered probabilistic sampling plan by gender and age on citizens from 5 to over 80 years old. Among them, the employees of the Oasi of Troina, many of whom were tested positive to the Covid-19 infection.
