The article is interesting, but it's obvious they picked the most alarmist, misleading headline possible, where they make it sound like this is likely to explode into a hyper deadly pandemic at any moment.
Both WHO and CDC considers the public health risk from avian flu low, but not non-existent. It's obviously important that these organizations monitor and stay vigilant about diseases like this, but there isn't any reason to believe we're looking at another pandemic or major public health crisis.
Here is the WHO's most recent report, which I really recommend going through if you get anxious from headlines like this: https://www.who.int/publications/m/item/updated-joint-fao-who-woah-public-health-assessment-of-recent-influenza-a(h5)-virus-events-in-animals-and-people_apr2025
