A Western Sydney aged-care home is in lockdown after a staff member who tested positive to coronavirus worked six shifts while showing symptoms of the deadly bug. The female staff member worked shifts at the Anglicare Newmarch House in Caddens, and Greystanes Disability Services in Leura while infected. On Saturday, the woman tested positive to COVID-19, leaving health authorities scrambling to identify her close contacts at the Caddens facility, where one resident has subsequently returned a positive swab for the virus. NSW Health says it is waiting for test results from a second ill resident at the aged-care home.
