That sort of thing sounds OK for primary/elementary school. You'd expect science at that level to be focused on soft stuff. Expecting kids of that age to do real experiments or care about the philosophy of science is too much, if you can get them out into the garden and looking at insects and flowers then that's a good start.

I think there's a subtle difference between viruses/bacteria and what government officials mean when they talk about infectious diseases. Obviously any good biology curriculum will cover viruses and bacteria at the microscopic level. But when governments talk about "infectious diseases" what they really mean is the macro scale of epidemiology and other social sciences, because they're constantly being told by rich NGOs that we now live in an age of pandemics, and they think about disease purely through the lens of social policy and enforcement. The response to COVID was widely condemned as un-scientific because link between what academics/civil servants recommended to governments and what was actually scientifically known about viruses was nearly non-existent.
