Such a tool is already provided by the NHS in the UK. When testing positive for a STI you receive the following message:"As you have an STI, you need to inform your *** partner(s). This will help to stop the spread of infections and save the NHS money.
You can do so anonymously via:
https://sxt.org.uk/". Trouble is, you need a phone number to use it and most times we don't have. To avoid the feature from being abused by some, it should only be available to users that have shared location.
