[Question] Why do EAs focus on global health over global development?

Something I’ve been wondering about is that it seems like, if your goal is to reduce preventable deaths, the best way to do so would be to help a country develop more efficiently so that, in the future, the country’s people have the necessary resources to prevent such deaths. As such, I would expect that EAs would focus on global development rather than global health since global health would temporarily fix the problem whereas global development would permanently fix it.

At the same time, EAs also seem to invest far more money into global health than global development. For instance, Coefficient Giving’s fund for global health is much larger than their one for global development.

As such, I’m wondering why do EAs focus on global health over global development?

Edit: Thanks for all the helpful responses!
