Is medicine a humanity?What does the humanity here refer to?

Yet humanity’s dramatic progress against specific infectious diseases has far outstripped the pace of investment in good health-care systems, responsive governance, dependable infrastructure, and the other more reliable guarantors of health.

This is from an article in The Atlantic, whose main point is that despite the great medical advances we are bad at handling public health crisis in many senses. Medicine is a science, not a humanity like literature or philosophy. So I think it should be "science’s dramatic progress". I’m very confused.

Solution 1:

"Humanity’s dramatic progress [...] Medicine is a science, not a humanity like literature or philosophy.

The first "humanity" is a synonym of "mankind"; "the human race" - In this sense, the noun is uncountable.

The second "humanity" in your example refers what the OED describes as

b. In plural (usually with the). The branch of learning concerned with human culture; the academic subjects collectively comprising this branch of learning, as history, literature, ancient and modern languages, law, philosophy, art, and music. Hence also in singular: any one of these subjects.The humanities are typically distinguished from the social sciences in having a significant historical element, in the use of interpretation of texts and artefacts rather than experimental and quantitative methods, [...].

[My emphasis]

NB: "medicine" = the area of study of medicine
