Study notes
COVID-19 (virus), tuberculosis (bacteria), malaria (protozoan), ringworm (fungus), elephantiasis (worm) — five pathogens, five kingdoms of trouble. Smallpox was humanity's greatest victory: the last natural case was 1977, declared eradicated 1980 — the only human disease ever wiped out. Polio is next in line — 99.9% gone since 1988.
