Across Sri Lanka as a whole, dengue is at 4.7× its usual; here it is 2.1×.

Why each district against itself. A large district always has more cases than a small one. Each dot is a district against its own usual, so size drops out.

And to a larger hospital?

Not shown yet. The Ministry of Health's list of its hospitals counts 5 larger hospitals in Trincomalee, and Dooram has not yet placed 2 of them on the map. Any of them could be nearer to people here than the nearest one placed, so a distance now could be too long.
