Contact tracing is about asking the patient where they have been in the last few weeks, identifying (tracing) every person they've been in contact with during that time, finding out where and how they caught the virus (ie the specific person they caught it from), and also finding and immediately quarantining everyone the patient has had contact with. It's not a process that necessarily needs PPE, more the ability to go through someone's Google Location History data and make lots of phone calls to people. Australia is even introducing an open source app next week (like Singapore has) to automatically collect Bluetooth IDs of nearby devices as a person walks outdoors, so people can be more easily traced & notified / quarantined if they've been in contact with someone who has been infected. Here's one of our Australian state government's explanation of contact tracing, in this case for Tuberculosis: https://www.healthywa.wa.gov.au/Articles/A_E/Contact-tracing-for-tuberculosis-TB https://www.healthywa.wa.gov.au/Articles/A_E/Contact-tracing...
