Genetic Technologies is developing a Polygenic Risk Score (PRS) test for COVID-19 which may enable an assessment of risk of an individual developing a serious disease should they contract the virus. The test is intended to predict ‘disease severity’ using a combination of genetic and clinical information (here). Modelling done by Sam Lovick Consulting using the results from the prototype shows that tailored work from home policies based on the test, when combined with precautions against infection for home-based workers, could reduce workforce hospitalisations by between 20% and 65% (depending upon the proportion of home-based workers and the extent of infection in the community); a company with 10,000 employees could potentially reduce hospitalisations by 290 resulting in 10 fewer deaths.
