I don't see a quote from the WHO that says this person died of bird flu, just that this person who was already very very ill was tested after they died and it was found they had bird flu.

They do call it "a confirmed fatal case of human infection with avian influenza A(H5N2) virus" though the report focuses more on it being the first confirmed human case at all than the fact that the person died.
Quite. Apparently all his family have tested negative, but one wonders if the virus is circulating around the hospital and he's just the first case to be tested. Reminiscent of early covid, when that Chinese doctor noticed an uptick of viral pneumonia in his ward. As well as the exhortations to remain calm and that the risk is low.
Screw remaining calm. We need to overreact, if anything, as long as there's a hope of containment. Lock the ward down, trace contacts, ring-vaccinate the community, cull the livestock, set up wastewater surveillance. I can't do this again.
I mean, I wouldn't call that inconsistent with symptoms of acute influenza...
