I am truly alarmed and completely unqualified to say this but I'll throw it there anyways - I would vote for reducing military spending by 90% and increasing pandemic R&D, hygiene and medicine spending by 10000%. If a nation is nuclear armed, we don't need a massive military perhaps.

H5N1 doesn’t spread well it’s primarily only bodily fluids hence why we only had about 800 confirmed cases.

It also doesn’t survive long at 37c or higher temps (6 days at 37c and drops fast from there).

Birds have higher body temperatures which helps to regulate the virus so while they can be carriers they are usually asymptomatic since the virus can’t replicate fast enough to cause major issues.
