And yes, this is a big deal. Public health emergencies of international concern are a short list consisting of, in their entirety: swine flu ('09 to '10), polio ('14 on), ebola ('13 to '16), Zika ('16), ebola ('19 to '20), Covid ('20 to '23), monkeypox ('22 to '25) and now this [1]. It's one step down from a pandemic emergency (which, to be clear, has not been declared).
