Como avaliar o risco de infecção na COVID 19.
Estudos mostram risco elevado em trabalhos considerados de "baixo risco"
Models show big infection risks in ‘low risk’ office work
New studies from the UK and the US, modelling virus risks in offices and other indoor environments, have concluded there is a potentially substantial risk of Covid-19 infection. Matthew J Evans of the Massachusetts Institute of Technology, who modelled Covid-19 aerosol transmission and used the findings to propose “guidelines for ventilation and occupancy in the workplace,” concluded: “Avoiding infection requires good ventilation and/or short exposure times. Generally, office spaces should not be occupied by more than one person.” Evans noted “a substantial body of literature has developed over the last few decades showing that the short-range aerosol route is an important, though often neglected transmission path.” Much of the current workplace guidance on social distancing and provision of personal protective equipment is based on close range ‘droplet transmission’ alone. Professor Clive Beggs of Leeds Beckett University, who also considered this issue, noted that unlike droplets, aerosols can “be widely distributed throughout room spaces.” He said the findings of his computer modelling study, which simulated transmission in an office building, “suggest that individuals who share enclosed spaces with an infector may be at risk of contracting Covid-19 by the aerosol route, even when practising social distancing.”
