The poem begins with something small and physical: the warmth passing between two hands, a warmth that comes from fever. Then it widens the picture. Two "lands" are also ill, and what ails them is money. The sound of "hands" and "lands" nearly matches, which nudges us to see one illness mirroring the other, the personal body and the larger body of nations or territories.
The final lines are the trickiest. "So much seeking" could mean searching for wealth, for cures, or for closeness, and the poem says that kind of searching is "sure to come home." That could be comforting, or it could be a warning that what we chase eventually returns to us, consequences included. The speaker doesn't say which, and judging by the flat, quiet tone, they aren't shouting a message. The mood is feverish but restrained: intimate, uneasy, and a little wry, as if the speaker is simply noting how sickness travels from a touch to a whole country.
