Guess the virus from taxonomic clues. Each guess reveals how close you are across 7 properties: family, genome, envelope, vector, host, receptor, and biosafety level.

An outbreak is unfolding. Reveal epidemiological clues one by one (R₀, incubation, CFR, symptoms, transmission, geography) and identify the virus before your score runs out.

A patient presents with an infectious disease. Work through the clinical findings (history, vitals, exam, labs, imaging) and diagnose the pathogen. Covers viruses, bacteria, fungi, and parasites.
