a flood spreading toward three Bangladeshi districts, and two ledgers that will not close

Water-borne risk is the forward problem; the ledgers are the standing one. In north-east Bangladesh, four rivers above danger with the risk reaching Sylhet, Sunamganj and Habiganj within 72 hours opens a water, sanitation and disease-surveillance window before the flood peak rather than after it — which is the only version of that work that is cheap. Nigeria's 15-state advisory to September 25 carries the same shape across a far larger population. Nepal is carried at a reported 1,410 or more dead and about 6,145 missing at a September 18 vintage and Pakistan frozen at about 183 dead and 515 injured — held where they are rather than re-counted, because a moving number treated as a fresh one is its own kind of harm. On the American board the heat-illness load has effectively ended: 1 Heat Advisory, 0 in the acute tier. (Handled with care.)
