NSW Health says 10 people at a Western Sydney aged care home have tested positive to COVID-19 in the wake of a staff member working six shifts there despite having symptoms of the virus. Residents at the Anglicare Newmarch House in Caddens, near Penrith, were placed in lockdown on Saturday after the female worker tested positive. Health authorities said she worked six days there and another two days at the Greystanes Disability Services in Penrith while infected. Six staff, including the woman, have now tested positive along with four residents. In a statement, Anglicare Sydney said all residents in its Caddens facility were self-isolating in its rooms and it had deployed staff specially trained in working with COVID-19 to work residents who had tested positive. It said all other staff had been directed to wear full personal protective equipment when caring for residents. The Penrith Greystanes Disability Service also quarantined residents in the house she worked and placed several of its staff in home isolation.
