Infectious Disease Compendium
For 20 years I maintained a infectious app.
Upkeep retired when I did, so it has not been updated since 2023.
Still, there is a lot of useful information and most entries link to appropriate puswhisperer blog entries.
It can be found here: https://publish.obsidian.md/pus-an-owners-manual, renamed Pus. An Owners Manual.
