Hi there, and welcome to my page!
I have great respect for scientific method, and I get very annoyed by misinformation, particularly around disease and vaccination.
Here's what I have done recently on Wikipedia
2023 to 2024 - making sure that the pages on pandemic and potential pandemic diseases (polio, dengue, influenza etc,) are reasonably accurate and up to date. Incidentally, there are about 140 pages containing either "influenza" or "flu" in the title. I'm not sure how many of them I have edited.
2024 - 2025 updating common haemoglobinopathies like sickle cell disease and thalassaemia
2025 - reviewing and updating tuberculosis and closely related pages, many of which are poor quality and fail to reflect developments, especially in drug resistance, over the last 10 to 15 years.
Go well, my friend.
